About Me

I am a PhD student at Computer Science and Automation department at IISc, Bangalore. Prior to this, I obtained my M.Tech and B.Tech degree from NIT Goa. Post M.Tech, I worked as a Software Engineer at Ruckus Wireless, Bangalore for a couple of months before joining IISc. Cryptography forms my broad area of research. In my spare time, I enjoy preparing desserts and watching movies.
