Hello! I'm Krithik Ranjan

I'm a first-year Ph.D. student in Creative Technology and Design (CTD) at the ATLAS Institute, University of Colorado Boulder, where I am advised by Prof. Ellen Do and Prof. Michael Rivera.

I am working towards the goal of enabling students from any economic background to tinker with technology and engage with computational thinking, even if they do not have access to computing devices. I explore and design low-cost technological solutions that not only teach children about computing but also enable them to create with technology and learn computational skills and practices.

I received my B.Sc. in Electrical and Computer Engineering from Cornell University in May 2022, where I worked with Prof. Cindy Hsin-Liu Kao, Prof. Jay Yoon, and Prof. Christopher Batten.
