Principal Investigator 

Theresa M. Desrochers, Ph.D.
Position: Rosenberg Family Assistant Professor of Brain Science,
Departments of Neuroscience; Psychiatry and Human Behavior (courtesy),
and Carney Institute for Brain Science

Post-Doctoral Fellows 

Katherine Conen, Ph.D.

Overview:I am interested in understanding how neural circuits represent the structure of behavior across time. Using approaches from systems neuroscience, I study how neurons in prefrontal areas encode information about sequence progression, focusing in particular on transition points in the task structure. Ultimately, this work will provide insight into the hierarchical and sequential relationships the primate brain uses to link percepts and behaviors into complex actions and predictive models.

Matthew Maestri

Overview: Prior to managing the Desrochers Lab, Matthew was a Research Assistant in a neuroscience lab at Augusta State University, formerly the Medical College of Georgia.

Graduate Students 

Nadira Yusif Rodriguez
Position: Neuroscience Graduate Student 

Overview: I am interested in identifying how and which brain areas support abstract sequence processing, focusing mainly on the role of the PFC during these sequential processes. Through the use of fMRI, statistical and instrumental behavioral tasks, I aim to determine the neural mechanisms involved, to understand these necessary abstract sequences that we use in day to day life. 

Aarit Ahuja
Position: Neuroscience Graduate Student

Overview: I am a shared student working in both the Sheinberg lab and the Desrochers lab. My main research interests include the neural basis of mental simulation/dynamic mental imagery, as well as comparative primate + human fMRI in general.

Hannah Doyle
Position: Neuroscience Graduate Student

Overview: I am broadly interested in using primate and human fMRI to study cognitive control mechanisms that dictate our day to day lives. In particular I aim to better understand brain areas involved in sequential processing and how these neural mechanisms might go awry in people with obsessive-compulsive and related disorders.

Undergraduate Students 

Kyoko Leaman ’23
Position: Undergraduate Research Assistant

Overview: I am a neuroscience and English double concentrator broadly interested in fMRI research investigating higher level cognition, particularly sequential processing and neurolinguistics. As part of this lab, I am looking forward to exploring the neural mechanisms of abstract sequence processing in the brain.

Rolake Feyisetan ’24
Position: Undergraduate Research Assistant

Overview: I am a neuroscience concentrator broadly interested in learning about how developmental and/or adverse events affect the brain and behavior. I look forward to using human fMRI to study how the brain processes sequential tasks in people with obsessive compulsive disorders. 

Claire Kim ’24
Position: Undergraduate Research Assistant

Overview: I am a neuroscience concentrator with research interests in the processing of abstract visual sequences and associations with cognitive processes. In the lab, I look forward to conducting analyses of electrophysiological data from task sequences in primates.


Sebastian Nunez (University of California San Diego) ’21
Position: Post-Baccalaureate 

Overview: I am broadly interested in how people do routine tasks that are organized into sequences and how sequential control relies on executive functioning. I am interested in using fMRI to study the neural activity in the Rostrolateral Prefrontal Cortex that is responsible for sequential control. I am currently working on understanding how OCD patients may have a deficit in the neural mechanism underlying sequential control, more specifically, a disruption in the RLPFC that inhibits their ability for sequential control.
