The U.S.-Israel Binational Science Foundation (BSF) has recently revealed the distinguished recipients of its competitive research grants for the years 2024–2025, reaffirming its mission to foster innovative scientific collaboration between researchers in the United States and Israel. Among the successful awardees are two leading academics from Reichman University who have secured grants for pioneering projects that blend profound theoretical insights with real-world applicability. Their research promises to push the boundaries of knowledge in psychology and computer science, areas vital to understanding human behavior and advancing computational capabilities.
Professor Gurit Birnbaum, a prominent figure at the Baruch Ivcher School of Psychology, embarks on an ambitious investigation concerning sexual desire within intimate relationships. Sexual desire is widely recognized to diminish over time, a phenomenon often attributed to the fading novelty and the gradual erosion of the fantasies that sustain attraction between partners. This universal dynamic can lead to critical relationship challenges, including the temptation to seek alternative partners and the consideration of relationship dissolution. However, existing studies present conflicting narratives on whether sharing sexual fantasies between partners acts as a bridge to rekindling desire or inadvertently undermines relational cohesion.
Professor Birnbaum’s project aims to delve deeply into the psychological mechanisms underlying the sharing of sexual fantasies and their relational consequences. By adopting methodologically rigorous approaches—encompassing experimental designs, observational data, and longitudinal analyses—her research seeks to determine the circumstances under which fantasy sharing may fortify the emotional bond between partners. A central hypothesis is that empathetic and warm responses to disclosed sexual fantasies critically influence whether the interaction will enhance relationship satisfaction and diminish susceptibility to extradyadic attractions.
The interdisciplinary nature of this inquiry necessitates carefully controlled experiments that simulate the intimate dynamics between couples, measuring intricate emotional and cognitive responses. Furthermore, longitudinal tracking over extended periods will enable the identification of causal pathways and developmental trends, elucidating how fantasy sharing impacts relationship stability and resilience to external temptations in real-life contexts. This nuanced investigation stands to resolve longstanding controversies in relationship science by integrating affective empathy as a pivotal moderating factor.
In collaboration with Professor Harry Reis from the University of Rochester, Professor Birnbaum’s work embodies a fusion of psychological theory and empirical innovation. Their joint efforts will likely yield theoretical frameworks and evidence-based insights that not only advance academic understanding but also inform clinical interventions and couples therapy strategies aimed at sustaining sexual desire and relational satisfaction over time. This research acknowledges the complex emotional landscape of intimate relationships and endeavors to translate scientific knowledge into practical applications for enhancing human well-being.
Concurrently, Professor Gil Kalai from the Efi Arazi School of Computer Science at Reichman University has been awarded a BSF grant for an ambitious project in collaboration with scholars from MIT, Bar-Ilan University, and the Hebrew University. This team of esteemed mathematicians and computer scientists focuses on expanding the frontiers of discrete Fourier analysis, a foundational mathematical tool with far-reaching implications across diverse scientific disciplines. Discrete Fourier analysis facilitates the decomposition of functions defined on finite domains, enabling profound insights into the structure and behavior of complex discrete systems.
A particular area of emphasis in this collaborative research is the development and refinement of hypercontractive inequalities. These mathematical inequalities play a critical role in quantifying how functions on discrete spaces behave under noise and transformations, offering essential instruments for understanding concentration of measure phenomena and measure stability. Enhancements in this area promise to unlock new theoretical and computational capabilities applicable across discrete mathematics, where analysis of combinatorial structures is paramount.
The implications of this work resonate deeply within computational complexity theory, where discrete Fourier analysis is harnessed to investigate the hardness of computational problems and design efficient algorithms. The research aims to construct novel analytical tools that can facilitate breakthroughs in classifying problem complexity and elucidating the limitations of computational models. By integrating representation theory—the study of abstract algebraic structures—and probability theory, the team endeavors to craft a sophisticated mathematical apparatus capable of addressing some of the most pressing open questions in theoretical computing.
Moreover, this research carries significant potential for advances in quantum computing, an emerging paradigm promising revolutionary computational speedups by exploiting quantum mechanical phenomena. The extension of discrete Fourier methods to quantum contexts could yield crucial insights into quantum algorithms, error correction, and information processing. The collaborative interdisciplinary approach blends deep theoretical mathematics with practical aspirations to catalyze progress in an area at the forefront of contemporary science and technology.
The BSF grants awarded to Professors Birnbaum and Kalai underscore the critical importance of supporting high-caliber research that bridges international scientific communities and amplifies intellectual exchange. These projects epitomize the transformative power of transnational collaboration, combining diverse expertise and perspectives to tackle complex challenges in both social sciences and mathematical foundations. The outcomes of such research will not only enhance academic disciplines but also generate applications that touch on human relationships and fundamental technological innovation.
Beyond their individual academic merits, the investigations funded by these grants vividly illustrate how cross-disciplinary collaborations can enrich scientific understanding and spur practical advancements. Professor Birnbaum’s work integrates psychological insights with behavioral methodologies to address intimate human dynamics, while Professor Kalai’s project leverages advanced mathematical theories to solve fundamental theoretical problems with broad computational impact. Together, they exemplify the diverse scope and ambition that the BSF aims to cultivate.
In a world increasingly shaped by complex human interactions and sophisticated technology, the research supported by the BSF represents a vital investment in intellectual capacity and innovation. By fostering collaborative links between U.S. and Israeli scientists, these grants contribute to a global scientific ecosystem that can respond dynamically to emerging challenges and opportunities.
