Research Experience

2018 - present Dartmouth College

Graduate Research Assistant

  • Developed statistical and machine learning methods to study the role of hippocampal neural representations in supporting generalization, including the cross-subject similarity in encoding related experiences and the representational geometry underlying fear generalization.
  • Investigated the role of replay in reshaping task representation and maintaining robust task performance in the brain and neural networks.
  • Established data collection and signal processing pipeline for simultaneous recordings of in vivo electrophysiology and fiber photometry.

summer 2022 Center for Computational Neuroscience, Simons Foundation

Summer Research Associate (PI: Alex Williams)

  • Optimized methods for aligning neural data and investigated necessary conditions to derive identifiable Procrustes transformations across neural representations.

2016 - 2018 New York University Shanghai

Research Assistant (PI: Jeffery Erlich)

  • Designed a sequential decision-making task and developed computational modeling of (hierarchical) reinforcement learning to study how sequences of goal-directed actions are coordinated in rodents.
