His work focuses on developing statistical technology that “wraps around” learning systems and ensures their reliability, accuracy, and stability. The tools Dr. Romano developed for prediction interval estimation were used by The Washington Post for reliable election outcome predictions in the 2020 U.S. elections.

 

Since 2005, the Krill Prize for Excellence in Scientific Research has been awarded annually by the Wolf Foundation and the Krill family, in memory and honor of Benjamin and Gittela Krill-Mansbach Schlanger. It is given to outstanding academic faculty members and promising researchers from research universities in Israel who have led significant research breakthroughs and are expected to lead research and academia in Israel in the future in the exact sciences, life sciences and medicine, engineering, and agriculture. The prize is funded by the estate of Avraham Hirsch Krill Schlanger, who was born in 1912 in Chemnitz, Germany. A year before the outbreak of World War II, Avraham Krill married Deborah Kertzic and emigrated to South America, where he established a successful textile factory. Avraham Krill was active in the community of Jews from Germany in South America and was an enthusiastic supporter of the State of Israel from its establishment. The prizes awarded in memory and honor of his parents symbolize the Krill family’s connection to Israel and their belief in the close relationship between science and vision.

 

The prizes will be awarded to the winners at a ceremony to be held in Ramat Hasharon on Tuesday, June 18, 2024, at 19:00.

Khalifa Award for Education

Dozens of candidates from UAE and the Arab world were awarded prizes in various categories, but there were only four international winners, including Prof. Horowitz-Kraus, head of the Technion’s group for brain imaging in children. She received the award in the category of outstanding research in the field of early childhood learning.

 

“It is hard to describe the warm embrace I received, not only from the international judges and hosts, but also from the Emirati royal family, who sponsored the event,” said Prof. Horowitz-Kraus. “I believe this is the beginning of a wonderful friendship and the start of fruitful and exciting collaboration. The award supports the importance and uniqueness of our research, which includes integrating tools from brain research to understand the basic processes supporting language and reading acquisition and examining the impact of intervention programs on these processes. The Emirati award shares our aspiration for a better future for children, based on quality education from an early age. This aspiration transcends cultures and fills me with hope for a better future and for building a bridge between countries, based in part on joint research.”

The Khalifa Award for Education aims to promote the development of education fields, create local and international interactions in the world of education, and foster new dynamics in the educational process, adapting it to current developments in scientific knowledge and information technologies. It was established by the late president of the UAE, Sheikh Khalifa bin Zayed, and continues under the current president, Sheikh Mohammed bin Zayed, under the sponsorship of Sheikh Mansour bin Zayed, vice president and deputy prime minister of the UAE.

 

The awards were presented at a special conference in education held in Abu Dhabi from May 14-15, and were personally awarded by Sheikh Mansour bin Zayed Al Nahyan. The ceremony was also attended by the wife of the Israeli ambassador to the UAE, Dr. Yifat Turbiner, who is responsible for cooperation in innovation and academic relations.

 

Prof. Horowitz-Kraus’s research focuses on the characterization of the neural networks underlying language and reading acquisition in children with language and reading difficulties due to neurobiological factors (e.g. dyslexia, ADHD, epilepsy, auditory processing difficulties, psychiatric disorders, etc.) and environmental deficits (e.g. lack of exposure to literacy or overexposure to screens). She also works on adapting intervention programs for each of these disorders, along with preventing language and reading difficulties using brain imaging tools such as MRI and EEG. In June, she will receive the Diane Sherman Prize for Medical Innovation for a Better World.

 

Prof. Horowitz-Kraus earned a bachelor’s degree in biology and a master’s degree in neurobiology and neurochemistry from Tel Aviv University. Additionally, she received a second master’s degree with honors in a clinical program for diagnosing and treating learning disabilities during her doctoral studies in the field of brain research of learning disabilities at the Edmond J. Safra Brain Research Center at the University of Haifa.

 

After completing her PhD, Prof. Horowitz-Kraus began her postdoctoral studies at the University of Haifa, searching for electrophysiological markers of the impact of intervention programs in children with learning disabilities, along with developing objective measures to evaluate the intervention programs that treat reading difficulties.

 

In 2011, Prof. Horowitz-Kraus received a Fulbright Scholarship for postdoctoral researchers and joined a research group in Cincinnati, USA, to use advanced imaging tools to characterize brain development in children, focusing on language and reading acquisition. Together with her partners in Cincinnati, she established the Literacy and Reading Research Center at Cincinnati Children’s Hospital and served as the program director and scientific director of the center from 2013 to 2021 and as a faculty member at the University of Cincinnati Medical School. Since 2021, she has been a part-time Associate Professor at Kennedy Krieger Institute and Johns Hopkins University, where she established and leads the Reading Research group.

Association of University Heads, Israel (VERA)

To the Governing Board of the Conference of Rectors of Spanish Universities,

We, the leaders of Israel’s universities and research institutions, are writing to express concern over your “CRUE statement on the violent situation in Gaza” and to offer our response. Let us be clear: we share your commitment to peace and justice in the region and thank you for your condemnation of antisemitism, Islamophobia, and other forms of hatred. We agree with you that the situation in Gaza is tragic.

We appreciated finding in your list of demands the cessation of “any action of a terrorist nature” and “freedom for the people kidnapped by Hamas.” We know that you are well-aware of the horrific events of October 7th, that included the brutal massacre of over 1200 Israelis and foreign civilians and the kidnapping of 240 people, among them toddlers, children, and young and elderly men and women. We ask that you keep in mind also what Israel has been experiencing in the weeks and months since October 7th. The Hamas has fired since then more than 10,000 rockets from Gaza and Hezbollah more than 5,000 rockets and drones from Lebanon, causing a massive evacuation and hundreds of thousands of internally displaced citizens. This situation, together with the mobilization of tens of thousands of young men and women for reserve duty, meant that for months Israeli universities could not open the academic year and researchers could not engage in research. Students and faculty were forced to leave their homes and many lost close family members – siblings, parents, children. Students were killed. Others were badly injured and forced to stop their studies. No one’s life or work has returned to normalcy. The grave weight of the war continues to take its unbearable toll and upend all areas of academic life.

It is with this context in mind that we are deeply concerned by your decision to “review suspending agreements with Israeli universities and research centers that have not expressed a firm commitment to peace and compliance with international humanitarian law.” This stance not only implies that the blame for the current situation rests on one side, but also presupposes the possibility that Israeli academic institutions are not dedicated to peace and to international humanitarian law. Nothing could be further than the truth.

We are compelled, therefore, to correct this misunderstanding by drawing attention to our policies and values.

 

1. We Stand for Democracy, Freedom of Speech, and Human Rights in Israel

 Against the backdrop of our country’s long history of political polarization, violent regional conflicts, and ethnic and religious tensions, universities in Israel have always been bastions of democracy, freedom of speech, liberal values, and human rights, including for Palestinians.

As you may know, last year it was from our campuses that the clearest voices emerged against the attempted judicial overhaul in Israel, which many feared would have weakened democracy and minority rights. Our leadership, faculty, and students took a leading role in opposing measures and legislation that would compromise the basic foundations of Israeli democracy.

Contrary to false allegations, we do not punish our students or staff members for expressing pro-Palestinian views. We are institutions that prioritize freedom of expression and we protect the rights of our faculty, staff, and students to express ideas that challenge the prevailing consensus even during these difficult and sensitive times.

 

2. Israeli Universities Are Independent Institutions

Lately, Israeli universities have been vilified for any link to the Israel Defense Forces, the supposition being that we are either directly culpable for our government’s actions or an agency of the military. We need to be clear: Israeli academia is independent of the government and military, and it operates autonomously in all academic matters. According to the 2024 Academic Freedom Index, which measures the state of academic freedom worldwide, Israeli universities are on par with universities in Norway, Canada, and Switzerland in upholding academic freedoms; moreover, we are ahead of countries such as the United Kingdom, the Netherlands, and the United States.

Faculty at Israeli Institutions make their own decisions on what to study and how to do so. While there are researchers at our universities who, in accordance with their academic freedom and rights, do research on subjects related to Israel’s security, there are academics in just about every other country who conduct research related to national security. Such projects, of course, represent only a small percentage of the research conducted at each of our universities and certainly do not turn our universities into military agencies.

This does not mean, however, that our academic community speaks with one voice when it comes to the current war. While there are faculty members at our universities researching on topics related to national security, we also have others who raise incisive questions and hold critical perspectives about Israel’s governmental and military policies in the current conflict. Our campuses are places where contentious issues are debated based on reason and fact, including all aspects of the war in Gaza.

Others suggest that our universities are guilty parties since our students are soldiers. As you must know, Israel is a small country; most young people here are required by law to enlist in the army when they are 18, and they later serve in the reserves. Since October 7th, many in our communities were enlisted. At the height of the war, approximately 25% of our students were called up for duty. These students (and some faculty members) risked their lives to protect their families, communities, and country. We all have students who haven’t returned alive. For those students who have returned, we have a duty to support their reintegration and their mental health. We are proud of the way we perform this duty, as we are sure every university in the world would be.

 

3. We are Dedicated to Bettering the Lives of Palestinians and to Promoting Peace

All Israeli universities are actively and extensively engaged in projects aiming to promote equality between Jews and Palestinians. 18% of our students are Muslim and Christian Palestinians, a figure that closely reflects their percentage in Israel’s population. Many of the Palestinian students study in our most competitive programs including medicine, computer science, engineering, and law. This reality is the result of extensive efforts and demonstrates the commitment of each one of our universities to equality and diversity and to promoting social mobility.

These efforts include providing extensive program of financial aid and fellowships for Arab students in all degree levels, including programs specifically encouraging and supporting promising candidates in advanced degree and post-doctoral programs.

The universities work hard to nurture multi-cultural campuses, taking seriously their responsibility to do so given that the period of study at the university is sometimes the first opportunity for meaningful positive interaction between Jews and Arabs. This requires not only recruiting diverse faculty members and students, but also creating a welcoming atmosphere and fostering meaningful learning opportunities across campus.

For decades, all our universities have spearheaded hundreds of projects and initiatives aimed at promoting peaceful relations in the region. Scholars in engineering, environmental studies, medicine, life science, and more collaborate regularly with counterparts in neighboring countries on projects designed to drive innovation on regional challenges in climate change, agriculture, sustainable development, public health and other areas (including collaborations with students in Gaza on water research). Other scholars work on promoting equity and social justice for Palestinian communities within Israel, including through our law clinics, educational initiatives, and community work. Our affiliated hospitals have regularly treated patients from Gaza and have also provided care for refugees from the Civil War in Syria. The space here is insufficient to even begin to enumerate all such projects.

 

4. The Danger of Academic Boycotts

 We understand that those calling for academic boycotts against Israeli universities aim to protect and improve Palestinian lives and to end the crisis in Gaza. The truth is that we too mourn the loss of innocent life in this horrific conflict and want a better future for Palestinians and Israelis both. However, academic boycotts are dangerous and may very well cause more harm than good.

Weakening Israeli academia would only undermine Israel’s democratic foundations, as well as the very community fighting to protect human rights and establish a more inclusive society. While many like to think the result of these boycotts would drive the type of change we saw in South Africa, tragically the result could be instead an increasingly militant and illiberal state, one less likely to promote regional peace, prosperity, and democracy.

In Israel, there is a high correlation between one’s level of education and one’s commitment to liberal democratic values, the rule of law, and support for a just solution to the conflict; teaching democracy and human rights is part of our educational mission. Our higher education system has helped Palestinian Israelis to achieve important positions in areas like law, medicine, the arts and high tech. Furthermore, our researchers are among some of the leading voices in Israel and globally for finding solutions for this crisis. Our academics remain steadfastly committed to peace, coexistence and international humanitarian law in the face of current challenges. Do Spanish universities want to weaken this force for good in the region rather than support it?

It is imperative that we reinforce academic collaborations to ensure that we live up to our shared global aspirations for a better collective future, and for the pursuit of knowledge and truth.

Respectfully,

The Dream is to Study at the Technion

About 400 excellent high school girls from across the country, from Paran in the south to Yanuh-Jat near the northern border, participated in the TechWomen2024 event at the Technion on Wednesday, May 8. At the event, now in its ninth year, the students were introduced to studies at the Technion and the opportunities available with an academic degree in science and engineering.

Rosalyn August generously supports the annual TechWomen events at the Technion. In a recorded greeting, she said, “I support this special program with my heart and money because I want to empower brilliant women like you. There is so much darkness in this world, and the Technion and the education you can acquire there represent the light. I have seen how women at the Technion are changing the world and I have no doubt that you have the power to change the world and bring the light.”

TechWomen events, sponsored by the Rosalyn August Girls Empowerment Initiative (GEM), have already led many high school girls to focus on science and technology studies and to choose to study at the Technion. Yarden Flash from Kiryat Motzkin, a student who recently returned to campus after three months of reserve duty, was a high school student when she came to the TechWomen2017 event seven years ago. Following the visit, she chose to study at the Technion and was accepted into the prestigious “Crystals” program in the Faculty of Materials Science and Engineering. After completing her bachelor’s degree, she continued to a master’s degree in the faculty and recently returned from a scientific conference in Austria.

Hila Litbak, who studied at Elon High School in Holon, came as a student to TechWomen2018. According to her, “the conversations with students in the faculties especially influenced me, and I decided to study at the Technion. I chose the data engineering track in the Faculty of Data and Decision Sciences  – the studies are challenging but also very interesting.”

Prof. Aylet Fishman, dean of students, who completed all her degrees at the Technion, talked about her personal and academic career. “I chose to study engineering so I would have a practical and challenging profession and so that I would always be independent. When I started studying, I didn’t think about an academic career, but life led me there,” she said, noting that “the world is currently flooded with fake news, for example in the food industry where I work, false claims that monosodium glutamate is poison and that frying with olive oil is forbidden. It is very important to always learn the facts and make decisions based on them.” She emphasized the most important message: “Believe in yourselves and your abilities, and you are invited to continue your studies at the Technion –  studies here will open many doors for you in academia and industry. Good luck.”

The special day began with breakfast, followed by an opening session led by Dr. Efrat Sabach from the Faculty of Physics. Dr. Sabach, an astrophysicist who also completed all her degrees at the Technion, said, “In such difficult times, when we are exposed to pain and mourning, and hoping for the return of the hostages, it is very heartening to see you, hundreds of outstanding students, arriving at this event from the Arava, from Sderot, from Ashdod, from Baka al-Gharbiyye, from Ma’alot, from Pardes Hanna, and beyond.” She noted that the Technion is celebrating its centennial year, introduced the various faculties, and shared a bit about herself. “As a child, I was curious,” she said, “and at age 12 I decided I would be a physicist. Physics is a science that explains everything – from the smallest things to the entire universe. That’s how I got to the Faculty of Physics at the Technion, where I did my doctorate in astrophysics under Prof. Noam Soker.”

Doctoral students Daniela Bar-Lev from the Taub Faculty of Computer Science and Yael Hershkovitz-Pollak from the Wolfson Faculty of Chemical Engineering talked about their academic paths and their current research. Daniela’s research deals with DNA-based data storage systems under the guidance of Prof. Tuvi Etzion and Prof. Eitan Yaakobi and she recently won the Schmidt Postdoctoral Award. Yael, under the guidance of Prof. Hossam Haick, is working on intercellular communication in the context of programmed cell death using diffusive organic molecules, aiming to develop targeted cancer treatments.

Limor Scheich, a grade coordinator, and Raya Attias, a teacher from the Gutwirth Comprehensive School in Sderot, came with 27 students and said, “We were received here with open arms. The hospitality was great, and the students had an excellent experience, especially in the faculty laboratories.”

Mai Almog, Ariel Abuhasira, Noam Medina, and Lianne Gabbai came in a group of 34 students from Mekif Zayn Comprehensive School in Ashdod. This was their first visit to the Technion. They are studying biology, biotechnology, physics, biology, and industrial engineering and management in various combinations, and according to them, “the dream is to study at the Technion.”

 

A Project in his Memory

Captain (res.) Denis Krokhmalov Veksler z"l
Captain (res.) Denis Krokhmalov Veksler z”l

Captain Krokhmalov Veksler was due to begin his studies this year in the Faculty of Aerospace Engineering at the Technion but fell in battle in the Gaza Strip on January 8, 2024.

The project to develop a communications satellite is led by Dr. Hillel Rubinstein from IAI, and Dr. Oded Golan, academic supervisor of student projects in the Faculty of Aerospace Engineering. The development of the satellite is the final project of a group of students from the faculty. The satellite will carry a detector for measuring gamma radiation, developed at the Technion’s Faculty of Physics. The satellite is called NOVA-SAT, in commemoration of the events of October 7th.

The satellite will perform measurements using the GALI (Gamma-ray Burst Localizing Instrument) detector developed at the Technion’s Faculty of Physics. This device is designed to detect bursts of gamma radiation, a product of the explosion of stars at the end of their lives, supernovae, and mergers of neutron star pairs. Since such astronomical events are difficult to locate, there is a worldwide effort to develop innovative detectors that will identify them and their locations. The GALI detector allows for precise identification of the direction of the burst, a feature characteristic of only of giant satellites rather than small systems. The detections it provides will enable astronomers worldwide to point telescopes at the event, study the burst, and link it to other events such as gravitational waves. The model that NOVA-SAT will carry was built by PhD student Julia Saleh-Natur.

Captain Krokhmalov Veksler was a respected athlete who immigrated to Israel at the age of 17. He lived in Be’er Sheva and served as an officer in the elite Yahalom (Diamond) engineering unit of the IDF Combat Engineering Corps. Despite being injured during triathlon training after his military service, Denis insisted on continuing to serve in the reserves while simultaneously pursuing his dream of studying aerospace engineering at the Technion.

 

The NOVA-SAT project embodies the vital connection between industry, education, and national memory.

 

Waves of Migration?

Dr. Naama Lang-Yona is studying the transport of microorganisms in the atmosphere and their effects on nature and humans.

We’re all aware of the bacteria in our bodies, how there are links between diseases and bacteria and viruses, and how pandemics spread. Those tiny organisms, found everywhere on the Earth’s surface, are also important in influencing various processes including soil health, pollutant decomposition, agricultural growth, and carbon sequestration. Dr. Naama Lang-Yona from the Faculty of Civil and Environmental Engineering is addressing a lesser-known aspect related to those microorganisms – their distribution mechanisms, survival, and activity in the atmosphere.

Dr. Lang-Yona’s research focuses, among other things, on the mutual influence (bio-exchanges) of the oceans and the atmosphere on the transportation of bacteria over the oceans. Bacteria constitute about 70% of marine biomass and play a very significant role in biogeochemical processes. Although they impact carbon, nitrogen, and sulfur cycles, little is known about their distribution and role in the environment.

Dr. Naama Lang-Yona
Dr. Naama Lang-Yona

In an article published this year, Dr. Lang-Yona and her colleagues at the Weizmann Institute of Science, Dr. J. Michel Flores, Prof. Ilan Koren, and Prof. Assaf Vardi, describe active bacteria found above the oceans. One of these bacteria, Roseovarius nubinhibens, is capable of killing algae. The research found that this bacterium is released into the atmosphere with the aerosol rising from ocean waters during the blooming of Emiliania huxleyi algae. While in the air, it managed to survive, retaining its ability to infect algae. These capabilities allow such pathogenic bacteria to expand their infection range and impact algal blooms spreading over thousands of square kilometers in the ocean.

Dr. Lang-Yona has published articles focusing on genomic mapping of airborne microbial populations (also termed bioaerosols) which traverse common thousands of kilometers above oceans, the dissemination of antibiotic-resistant genes through the air, the impact of climate change and air pollution on respiratory allergens (known as aero-allergens), the airborne transport of endotoxins, the characterization of different microorganisms in the environment, such as allergenic cyanobacteria, and the spread of airborne plant pathogens, and more.

Currently, Dr. Lang-Yona and her team are conducting research on the distribution of bacteria via dust storms reaching Israel all the way from the Sahara and Arabian deserts. Their aims are to elucidate the survival mechanisms and distinctive traits of these bacteria. In addition, they examine the idea that along with the bacteria carried and dispersed in the air, antibiotic resistance may also disperse and propagate across continents.

These studies have dramatic implications for understanding the transmission of diseases and pandemics, as well as for devising strategies to impede their dissemination.
