I am the Elmore Rising Star Assistant Professor of Electrical and Computer Engineering (ECE) at Purdue University, where I lead the ION research lab.

ION conducts research at the intersection of networking, communications, and machine learning. Contemporary network architectures we investigate include Fog computing systems, the Internet of Things (IoT), NextG Wireless, and social learning networks (SLN), and our foundational techniques include convex and non-convex optimization, machine learning, and signal processing.

Since joining Purdue, I have been fortunate to receive several external early career research awards, including NSF's CAREER Award, ONR's YIP (Young Investigator Program), DARPA's YFA (Young Faculty Award), and Intel's RSA (Rising Star Faculty Award). Check out my CAREER project webpage for more details on this project too.

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. I also co-founded the big data startup company Zoomi Inc based on my research.

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.

Note to prospective postdocs: I am looking to recruit one postdoc to conduct research on fog/edge learning. If you are interested, please send me an email with (i) your CV and (ii) a brief statement of research. I apologize in advance that I cannot respond to every email.

Note to prospective graduate students: I am not actively recruiting. However, I am always interested in connecting with highly motivated students in case an opportunity arises. If you want to conduct research with me, 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.
