Aaron Fisher is an Associate Professor of Psychology and the director of the Idiographic Dynamics Laboratory at the University of California, Berkeley. He received his PhD from the Pennsylvania State University in 2012 and joined the Department of Psychology at UC Berkeley in 2013 after a postdoctoral fellowship at Stanford University.
Dr. Fisher’s research seeks to measure, model, and understand dynamic processes in individual behavior and health.

Hannah Bosley is a PhD candidate in Clinical Psychology at UC Berkeley. Her research aims to quantify and predict emotional experience at the level of the individual. Understanding individual patterns in emotional experiences and how these may relate to mental illness will ultimately yield answers to questions like: what emotions does an individual most need to regulate? How do we know when a particular emotion state will occur? What leads to change in these emotion states over time? Hannah's dissertation work seeks to understand the timescale of emotions as measured through experience-sampling, with an eye toward how findings might help us optimize the sampling of emotion in ecological momentary assessment designs.
Less related to her current research, Hannah also gets a kick out of thinking about synesthesia, free will, linguistics, the ocean, true crime, and dogs.

Jonathan Reeves is a PhD candidate in Clinical Science at UC Berkeley. His research aims to better measure, model, and predict self- and other-directed violence. He is particularly interested in building personalized models that can predict these behaviors before an individual engages in them and understanding how the day-to-day experiences of survivors can help us identify and assist those most at-risk. To do this, Jon’s work leverages smartphone technology to track individuals' thoughts, feelings, and behaviors over time to understand how these experiences interact for each individual. He hopes to eventually use this work for data-driven real-time intervention applications. Finally, while much of his work focuses on helping one individual at a time, Jon is interested in the efficacy of large-scale public health interventions for these problems.

Allison Diamond Altman is a PhD candidate in Clinical Science at UC Berkeley. Broadly speaking, Allison is interested in affective science and in employing idiographic approaches to research and treatment. While in graduate school, her masters' thesis investigated affective forecasting differences in dysphoric and healthy individuals, using an idiographic approach. She plans to continue using such personalized methodology on her dissertation, which will look at specific mechanisms underlying social media use and mood changes in healthy and clinical samples. She feels passionate about disseminating science to the public, and in her free time likes to run, do yoga, and play with her Doberman.

Peter Soyster is a third year graduate student in the Clinical Science Program. He received his BA in Psychology from UC Berkeley in 2015. Is it possible to accurately predict when someone will use a drug, hours before they use it? If so, could such knowledge be used to improve treatments for substance use disorders? Peter’s research employs idiographic methods to understand substance use dynamics and predict future use at an individual level. Specifically, he is interested in understanding how biological, psychological, and social factors contribute to momentary decisions to use tobacco and alcohol. In his free time, Peter enjoys playing bass guitar and wrestling with his cat.

Stefan Westernmann is a visiting scholar at UC Berkeley and was previously a postdoctorla scholar at the University of Bern, Switzerland. He obtained his PhD in clinical psychology in 2011 from the Philipps-University of Marburg, Germany and is a licensed psychotherapist in Germany and Switzerland. Dr. Westermann models the dynamic interplay of motives, interpersonal relationships, and learning to answer questions such as, “How does a client learn from novel experiences within the therapeutic relationship?” (Please see http://syntopics.com). Besides that, he is interested in internet-based interventions and psychological therapies for people with psychosis.
