Advising Statement

Research Interests:

Timescales are a fundamental concept used to analyze the duration and progression of events across various domains, from natural science to human activities and psychopathology. Recent advancements in large-scale electrophysiology and ultrahigh-field MRI have enabled us to investigate neural, behavioral, and disease progression timescales in macaque models with unprecedented spatial and temporal resolution. We operationalize this concept across three key areas: mapping baseline neural dynamics through whole-brain resting-state fMRI and large-scale electrophysiology, exploring the coordination between neural and behavioral timescales in ecologically valid settings, and examining how neural dynamics evolve over time in chronic conditions such as substance use disorders. Moreover, we are interested in mapping the effects of GLP-1 receptor agonists on the healthy brain and exploring how they may serve as therapeutic interventions for substance use disorder. Finally, we are studying the neural correlates of usefulness and decision-making using a modified version of Tetris and Neuropixel probes. Together, these efforts leverage cutting-edge techniques to deepen our understanding of neural dynamics, behavior, and disease progression, with a strong translational focus.
