Chaitanya Kumar

Security, Privacy, Blockchain

I am presently a Blockchain researcher at IBM Research, Singapore.
My academic interests span across distributed systems, privacy, legalities in the cyberspace and program analysis. I completed my Bachelor's in Tech from IIIT-Delhi, majoring in Computer Science.
I have always been engaged in building and discussing secure and privacy preserving systems, through my academic and professional pursuits.
Over the years, I've become more interested in the human aspect of making systems secure and/or privacy-preserving.

Interests

When I'm not working or debugging, I enjoy reading books and hiking about. I've lately taken to indoor climbing and learning to play the piano.
I also tend to write, sometimes technical, often not.
Besides my academic interests in computer science, I also dabble with reading into other domains, such as cosmology; and more recently, economics to better understand the economics of information security.
I'm always happy to catch up if any of these things get you excited! 🍻
