I am a fifth year computer science PhD student at the University of Wisconsin-Madison. I am a member of the SCAIL research group led by Prof. Michael Swift.

Prior to pursuing my graduate studies, I spent a year as a Research Assistant at the Indian Institute of Science (IISc) advised by Prof. Arkaprava Basu and Prof. Vinod Ganapathy.

I obtained my bachelor's degree in Electronics and Communication (ECE) from PES University.

Research interests

My research interests include computer architecture and systems broadly.
During my PhD, I have focused on designing architectures for new and upcoming memory and storage technologies such as Non-Volatile Memory, low-latency SSDs and CXL technology..
I have a keen interest in hardware-software co-designs. I believe that they present significant performance and efficiency opportunities that are unavailable without crossing the boundary between the two layers.
