About
I am a PhD student in the joint Neural Computation and Machine Learning program at Carnegie Mellon University (CMU). I am co-advised by Matthew Smith and Byron Yu.
Previously, I was a Research Scientist Intern in the CTRL Labs division at Meta Reality Labs (Summer 2024).
I graduated from UC Berkeley (Go Bears!) in Fall 2018 and received a BA in both Computer Science & Molecular Cell Biology: Neurobiology.
Research Interests
- brain-machine interfaces
- dimensionality reduction
- dynamical systems
