Theresa McKim, Ph.D.

Overview: I am interested in the neural mechanisms underlying goal-directed sequential behavior, and the role of the prefrontal cortex in exerting cognitive control to flexibly adapt sequential actions. Understanding the neural circuitry of sequential tasks will enable future investigation into how deficits in regulating sequential decisions may contribute to disorders such as addiction.

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 do day life. 

Undergraduate Students




Eojin Choi
Position: Undergraduate Research Assistant
Overview: I am a junior studying neuroscience and STS (science, technology, and society). In addition to gaining more experience with research methods like fMRI and TMS, I am interested in studying the effects of OCD on sequential control and behavior.




Juliana Trach
Position: Undergraduate Research Assistant 

Overview: I am a senior studying cognitive neuroscience. Currently, my main project is working on writing my thesis. I am studying how motor and abstract sequence processing interact during sequence acquisition and execution. After Brown, I want to continue studying the brain in graduate school, particularly focusing on studying the relationship between cognitive development and language acquisition.




Meghan Hershkowitz

Position: Undergraduate Research Assistant 


Overview: Meghan is currently a junior concentrating in Biology. During her time in Dr. Desrochers lab, she is looking forward to learning more about the neural bases of sequential processing. When she's not in the lab, she's busy working as an EMT and volunteering at The Miriam Hospital. 



Victoria Flagg

Position: Undergraduate Research Assistant 


Overview: Victoria is a senior at Brown studying Neuroscience. During her time in the Desrochers lab, she has enjoyed learning about and helping with studies utilizing cognitive computer tasks, TMS, and fMRI. 



Gabriela Batista

Position: Undergraduate Research Assistant


Overview: Gabby is a sophomore at Brown studying Neuroscience. During her time in the Desrochers lab, she aims to to elucidate the neural mechanisms underlying sequential processing and think about how these findings may be applied to the psychiatric field.
