My research focuses on identifying the neural mechanisms of cognitive deficits in Alzheimer’s disease and developing novel systems for tracking animal behavior using machine-learning. I am interested in applying frameworks and analysis methods from the fields of animal learning theory, behavioral neuroscience, and artificial intelligence to gain a deeper understanding of the processes underlying impairments in time perception and memory.

Research Interests:

• Understanding the neural computations underlying time perception and how these processes are disrupted in Alzheimer’s Disease.
• Developing novel technology for automated tracking and segmenting behavior of freely moving animals using thermal imaging and deep-learning techniques.
• Integrating neuroscience methods such as in vivo electrophysiology with machine-learning tools for tracking behavior and computational modeling of decision-making.
