About me

I am Heejin Park, a Ph.D. student at Purdue University, working in XSEL advised by Prof. Felix Xiaozhu Lin. My general research interests cover Operating and Distributed Systems. Currently, my research focuses on the Internet of Things (IoT) and edge computing. In particular, I am working on building a stream analytics engine at the edge regarding its performance, security, and reliability.
