I am an Assistant Professor in the Computer Science and Engineering Department at Michigan State University (MSU). Prior to MSU, I was a Post-doc in the Computer Science Department at UMASS Amherst, working with Prof. Deepak Ganesan. I received my Ph.D. in the Computer Science Department at Dartmouth College in 2020. My Ph.D advisor was Prof. Xia Zhou. I earned my M.S. at Dartmouth College in 2014 and B.E. with honor from Australian National University in 2012.

My research interests are in wireless communication, sensing, and low-power systems. Specifically, my Ph.D. work focuses on designing novel human sensing systems using light. My vision is that light can be a primary modality for fine-grained human sensing. Using small, cheap, and low-powered photodiodes around us, we can sense the light intensity change caused by the human blockage, reflection, and absorption and then infer fine-grained human behaviors and some biomarkers. My work on light-based sensing won MobiCom Best Video Award in 2015, and was selected as a Best Paper Nominee at SenSys 2017, SIGMOBILE Research Highlights in 2016 and 2018, and CACM Research Highlights in 2018. I have also received MobiSys Best Demo Award in 2015, VLCS Best Paper Award in 2014, and UbiComp Best Paper Nominee Award in 2014.

I have multiple fully-funded Ph.D. student positions (Spring'22 and Fall'22) in the areas of mobile health, mobile systems, AI-related sensing technologies, and ubiquitous computing. Please send your CV and transcripts to me via litianx2@msu.edu if you are interested.
