Meet Our Team
We are a diverse, friendly, and collaborative group of curious minds and critical thinkers, passionate about rigorous, open, and impactful science. We value mutual respect, open dialogue, and the joy of discovery. Whether in the lab or over coffee, we believe science should be fun, transparent, and impactful. We are always excited to meet new colleagues, collaborators, and students who share these values.
Dr. Rotem Botvinik-Nezer

Principal Investigator
I am a cognitive neuroscientist interested in how beliefs are formed, updated, and influence behavior, perception, and health, at the individual and social levels. My academic journey started with a B.Sc. in psychology and biology with emphasis on neuroscience at Tel Aviv University. I then completed a direct Ph.D. program at the Sagol School of Neuroscience, also at Tel Aviv University, where I studied behavior change, brain plasticity, decision making, and analytical variability in neuroimaging.
After my Ph.D., I moved to Dartmouth College for a postdoc, focusing on belief updating, placebo effects, and expectation mechanisms, combining computational modeling, pain experiments, and neuroimaging.
Since the fall of 2024, I’ve been a senior lecturer (Assistant Prof.) at the Psychology Department of the Hebrew University of Jerusalem, where I lead the RBN Lab. I am excited about better understanding belief updating and placebo effects, and translating this understanding into practical interventions that would make a real change in the world. I’m also passionate about open, reproducible science.

Devora Newman
Postdoctoral Researcher
I'm Devora, a post-doctoral research fellow having recently completed my PhD in the Department of Psychology at the Hebrew University of Jerusalem, under the guidance of Prof. Ruth Mayo. In my doctoral work, I focused on the ability to discern truths from falsehoods and the individual traits correlated with lessened discernment. Additionally, I examined the crucial role of the "I don't know" response when measuring reliance on misinformation, showing that including it allows for a more accurate expression of individuals' knowledge. I am currently interested in better understanding how people sample their social surroundings when determining the veracity of information, specifically how the perceived frequency of true and false information influences inferences and consequent belief updating.
I believe that science is a team effort, and I love working with colleagues and students on questions that matter right now, especially how misinformation affects our everyday decisions, and why good science is essential for a healthy democracy.

Eli Adler
Postdoctoral Researcher
Hi, I’m Eli, a social psychologist and neuroscientist. I am broadly interested in how people make sense of social and political conflict, particularly how beliefs, emotions, and group identities shape the way they interpret information, evaluate other groups, and make political decisions. Much of my research has focused on the Israeli-Palestinian conflict and polarization within Israeli society, examining why people sometimes resist challenging perspectives and what can make them more open to them. I am especially interested in using technology both to deliver psychological interventions and to study the underlying mechanisms. My work takes a multimethod approach, combining various measures such as self-report, behavioral, implicit, and neural measures to reduce reliance on any single source of evidence and capture processes that people may be unable or unwilling to report accurately. Ultimately, I hope to understand what changes people’s minds, for whom such change occurs, and when it persists and influences real-world behavior. I am especially interested in how beliefs and emotions form and update, and in developing psychological interventions that foster empathy, flexible thinking, and more constructive intergroup and intragroup relations.

Roee Kaplun
Ph.D. Student (Direct Track)
I’m Roee, a Ph.D. student in Psychology at the Hebrew University of Jerusalem and a recipient of the Insight Fellowship for Outstanding Doctoral Students. My research asks how placebo effects can be harnessed and enhanced to improve patient care. I study how the information patients receive about a treatment shapes the relief they experience, and how this framing can be tailored to the individual patient. Alongside my lab work, I collaborate with Sheba Medical Center on research into chronic pain, studying how patients’ illness perceptions, broader beliefs, and past trauma shape the way they experience pain.
I hold a B.A. from Tel Aviv University’s Philosophy, Politics, and Economics (PPE) Excellence Program, with a minor in Law. Outside the lab, I have a deep interest in meditation and in how contemplative practice can change the way we relate to physical and emotional suffering.

Sapir Zamir
Master's Student
Hi! I’m Sapir, a Master's student in Rehabilitation Neuropsychology. I completed my undergraduate studies in Law and Psychology at the Hebrew University. My research will examine how people update their beliefs about treatments and natural recovery, and whether they consider alternative explanations rationally. I am also interested in individual differences and how these effects may vary across different contexts or over time.
Outside the lab, I am interested in the intersections between psychology and law.

Hadas Erenfeld
Master's Student
Hi, I’m Hadas, a master’s student in clinical psychology
Before that, I studied computer science and mathematics and also completed an M.Sc. in computer science. Over the past two years, I’ve been studying in the Completion Program for a Master's Degree in psychology, here at the Hebrew University.
In my research, I hope to combine the computational world with the field of psychology, where I’m just taking my first steps. Besides that, I’m also a mom to a sweet little girl (objectively speaking :)

Yehuda Myers
Master's Student
I’m Yehuda, currently pursuing an M.A. in Adult Clinical Psychology. I hold a B.A. in Psychology and Economics from the Open University of Israel. My research focuses on the placebo effect and the psychological mechanisms that shape a patient’s trust and belief in their prescribed treatment. Specifically, I examine how tailoring treatment descriptions to match an individual’s characteristics and prior beliefs can enhance treatment-related expectations. Beyond my research, I am deeply interested in psychopathology and the diverse therapeutic approaches developed to alleviate psychological distress and promote well-being.

Rivka Hagma
Master's Student
I am Rivka, a Master's student in Psychology. I completed my undergraduate studies in Psychology at Bar-Ilan University, magna cum laude. My research focuses on how the placebo effect manifests in daily life, with particular interest in its neurobiological aspects, perceived immunity, as well as the dynamics of belief updating, expectations, and attributions over time. I believe in a personalized approach and an integrative perspective, utilizing computational models.

Mika Sagi
Research Assistant
I'm Mika, a Computer Science and Cognitive Science student at the Hebrew University. I'm fascinated by the interplay between human and artificial cognition. I aim to contribute to a deeper understanding of cognitive processes through computational modelling, and explore how those findings can inform and advance the field of machine intelligence. My current research focuses on dynamics of belief systems.
