Computer Science & Engineering,
The Ohio State University
My research interests span several areas such as privacy-preserving data analysis, machine learning, security, and information and coding theory. I am broadly interested in studying the tension/harmony between data analysis and machine learning on one hand and other notions of central importance to people and society such as privacy and security. In my work, I enjoy applying various tools from several areas such as information and coding theory, statistics, and optimization.
My research focuses on tackling current challenges in data analysis and machine learning especially those of direct impact on society. Much of my recent research effort has been devoted to developing practical algorithms with rigorous guarantees for privacy-preserving data analysis. The goal of this area of research is to enable conducting highly accurate analyses over private, personal data while providing rigorous guarantees of privacy for individuals whose data are collected; that is, to achieve the seemingly paradoxical goal of learning from private data without learning private data! Part of my research also addresses fundamental questions in machine learning and privacy.
Since Fall 2017, I have been an assistant professor in the Department of Computer Science and Engineering at The Ohio State University. Before joining OSU, I was a data-science postdoctoral fellow at University of California, San Diego. Prior to this, I was a postdoc in the Department of Computer Science and Engineering at The Pennsylvania State University. I completed my PhD in Electrical and Computer Engineering at University of Maryland, College Park, in 2012.

Note to Prospective Students:
I am looking for bright, self-motivated PhD students to recruit. If you are interested in working with me on one or more of the topics in the link below, feel free to send me a brief email with your background and your resume (including any relevant coursework you have done). Also, taking one of my classes (e.g., CSE 5223: Machine learning theory this Fall) and doing very well is a plus. If you are not currently admitted to OSU, you are encouraged to apply. If that is the case, you are still welcome to send me an email, but, please keep in mind that admissions are decided by the department/university committees.
