I am a PhD student in the ECEE department at Arizona State University (ASU). Here, I am part of the Geometric Media Lab and I am advised by Pavan Turaga.

I received my MS degree from ASU, during which I worked as a computer vision algorithm developer under Pavan Turaga. I've spent time as an intern at Mayo Clinic, Lawrence Livermore National Laboratory and Roche.

My research interests lie in computer vision, computational topology, differential geometry, dynamical system analysis, machine learning and deep learning. My research centers around analyzing and modeling time-series data collected from different sensing devices, for the following applications - human activity recognition, movement quality assessment, Parkinson's disease severity assessment, electrocardiogram (ECG) signal analysis.
