I build robots that see, decide, and act — transforming multimodal sensing into precise autonomous action.

Final year PhD Candidate at Duke University working with Patrick Codd and Boyuan Chen, working across multimodal perception, surgical autonomy, and machine learning. My systems close the loop from raw sensory data to real-world intervention.

About

Background & Vision

I am a doctoral candidate in the Brain Tool Lab at Duke, advised by Patrick Codd, M.D. and Boyuan Chen, Ph.D. My work sits at the intersection of robotics, multimodal perception, and surgical systems.

I build closed-loop platforms that transform rich sensory data into precise autonomous action — from autonomous laser surgery (OCT + fluorescence + cutting lasers) to neural implicit representations for surgical navigation, acoustic sensing for multi-drone coordination, and multimodal tactile sensing for tissue assessment.

Before Duke, I co-led Futures+ across four countries and founded TEDxNITW. These experiences inform how I think about technology design for communities that need it most.

I serve as Lab Manager at the Brain Tool Lab and am Instructor of Record for a Bass Connections course developing teleoperated surgical systems for rural clinics.

I am on the academic job market seeking faculty, postdoc, and research positions in robotics.
