Lab Director

Michael T Treadway, PhD

Dr. Treadway is a clinical psychologist and neuroscientist focused on understanding the molecular and circuit-level mechanisms of psychiatric symptoms related to mood, anxiety, and decision-making. He received his PhD in clinical psychology from Vanderbilt University in 2012, and completed his clinical internship and post-doc at McLean Hospital/Harvard Medical School. As Director of the Translational Research in Affective Disorders Laboratory (TReADLab) in the Department of Psychology at Emory University, Dr. Treadway’s research employs a variety of methods, including multimodal neuroimaging techniques (fMRI, MRS, and PET), behavioral paradigms, computational modeling, and clinical/personality assessment. A particular interest has been the assessment of reward motivation in psychiatric populations, for which Dr. Treadway has developed several laboratory tasks, including the Effort-Expenditure for Rewards Task (EEfRT).

Assistant Director

Jessica A Cooper, PhD

Dr. Jessica Cooper is an Assistant Professor in the Department of Psychiatry and Behavioral Sciences at Emory University with research interests in motivation and decision making. She received her PhD from the University of Texas in 2016, where she primarily studied decision making and reinforcement learning in healthy aging. Her work in the TReAD lab focuses on characterizing neurobiological and computational mechanisms of motivation and effort-based decision making in both healthy and clinical populations. She employs a variety of methods, including computational modeling, behavioral paradigms, functional magnetic resonance imaging (fMRI), and ecological momentary assessment (EMA). Jess has been funded by a Ruth L. Kirschstein Postdoctoral Individual National Research Service Award (NRSA) as well as K01 award from the National Institute of Mental Health.

Post Doctoral Research Fellows

Jon Ryan, PhD

Dr. Ryan graduated from Florida State University with a Ph.D. in Neuroscience prior to joining the TReaDLab. His primary research interests lie in utilizing neuroimaging and neuromodulatory techniques to parse underlying mechanisms associated with depressive symptomatology. He hopes to work towards the development of novel clinical interventions for treatment-resistant depression.

Wenwu Sun, PhD

Dr. Wenwu Sun holds a Ph.D. in Physics from the University of Georgia, specializing in brain connectivity analysis using neuroimaging and machine learning in procine model. His research focuses on integrating structural and functional brain data to improve understanding of neurodevelopment and brain injury recovery, particularly in porcine models. He aims to improve understanding of brain function and contribute to the development of clinical applications


Graduate Students

Shosuke Sosuki, MA

Shosuke graduated from UCLA with a B.S. in Neuroscience. Before joining the TReAD lab, he spent 3 years working as a research assistant at Yale University, where he gained experience running multi-session clinical trials with fMRI and EEG components in Substance Use Disorders. He is primarily interested in using ecological paradigms to examine the interface between motivation and action. He is an NRSA fellow and currently on internship at Dartmouth. Outside of lab, he enjoys cooking, bouldering, and meditating.

Summer Frandsen, MA

Summer graduated with a B.S. in Psychology and minors in Statistics and Ancient Near Eastern Studies from Brigham Young University and an M.A. in Psychology from Brandeis University. During this time, she also worked as a research assistant in multiple labs including the MEND2 Lab at the University of Utah and the Center for Brain Circuit Therapeutics at Brigham and Women’s Hospital/Harvard Medical School. Summer is interested in harnessing multimodal and causal methods to understand the underlying transdiagnostic mechanisms of psychiatric disorders and their treatments. She has a particular interest in brain stimulation as both a treatment modality and a research tool. She is currently an NSF Graduate Research Fellow.

Sarah Etuk, MA

Sarah graduated with a BA in neuroscience from Pomona college, and then completed the NIH PREP program at Northwestern University. Her work in the lab has focused on examining the role of inflammation and immunometabolism in context of motivational impairments in mood disorders. She is also interested in the neurobiological consequences of early life adversity and their role in the development of mental illness. Her work is currently funded by an NIMH supplement award.

Marta Migo, MA

Marta graduated from New York University with a B.A. in Psychology, a B.F.A. in Drama, and minors in Computer Science and Philosophy. She then worked as a Clinical Research Coordinator at Harvard Medical School/Massachusetts General Hospital for two years, in the Division of Neurotherapeutics. Currently, Marta is interested in using neuroimaging and computational psychiatry techniques to study free and perseverative thought patterns, such as worry and rumination, in mood and anxiety-related disorders.


Research Staff

Srinidhi Jayakumar, MA

Srinidhi Jayakumar graduated with a B.Sc. in Psychology from Virginia Tech in 2021, and a M.A. in Psychology from Stony Brook University. She is primarily interested in identifying psychophysiological predictors for the development and trajectory of depression and suicidality in adolescents and young adults employing a multi-method approach (e.g., incorporation of fMRI, EEG, and neuroimmunology). She aspires to complete a PhD in Clinical Psychology in the near future.

Tatiana Pillsburry, BA

Tatiana graduated from New College Florida with a degree in Neuroscience.

Oluwagbohunmi Aje, MA

Oluwagbohunmi graduated from Stony Brook University with an MA in Psychology before joining the TReaDLab. His primary interest lies in using neurobiological and neurocomputational techniques to understand the association between affective deficits and disinhibited behaviors across various psychopathologies. 

Jessica Kubert, BA

Jessica Kubert graduated from Emory University where she majored in psychology.

Samantha Betters, MS

Samantha (“Sammie”) graduated with a degree in biomedical engineering from the University of Florida and an MS in healthcare engineering from Johns Hopkins University


Caroline Conway, BA

Caroline Conway graduated from Dartmouth College in 2024 with a B.A. in Cognitive Science and minors in Psychology and Hispanic Studies. She is interested in interventions for treatment-resistant depression, with a particular focus on neuromodulation and methods that are non-invasive and accessible. She is also passionate about leveraging neuroimaging to identify biomarkers of major depressive disorder and other psychiatric conditions.
