I am an Assistant Professor of Electrical and Computer Engineering at Purdue University.

My research is at the intersection of data science and networking. My group develops data-driven optimization methodologies for communication and social networks, with a particular emphasis on distributed edge intelligence. Contemporary network architectures we investigate include Fog computing systems, the Internet of Things (IoT), and social learning networks (SLN), and our foundational techniques include convex and non-convex optimization, machine learning, and signal processing.

Prior to joining Purdue, I was the Associate Director of the EDGE Lab and a Lecturer of Electrical Engineering at Princeton University, where I received my PhD. My PhD thesis won the 2016 Bede Liu Best Dissertation Award in Electrical Engineering. I also co-founded the big data startup company Zoomi Inc based on my research, which has provided employee performance optimization to more than one million users worldwide.

I am also active in teaching. In addition to lecturing, I co-authored the book The Power of Networks: Six Principles That Connect Our Lives and have taught three Massive Open Online Courses (MOOCs) on networking. Together, these MOOCs have reached over 400,000 students around the world since 2012.

Note to prospective graduate students: I am not actively recruiting, but I am always on the lookout for highly motivated students who want to conduct research in my area. If you fit this description, feel free to send me an email that contains at least (i) your CV and (ii) something which demonstrates to me that you have read one of my recent papers. I apologize in advance that I cannot respond to every email.
