Prof. Berry’s research covers resource allocation problems that arise in networked systems ranging from communication networks to social networks. This work uses mathematical models to gain insights into such systems and draws on tools from stochastic modeling, optimization, economics and algorithms. Specific topics of current interest include developing distributed resource allocation technicques for wireless networks, dynamic spectrum sharing and wireless spectrum policy, understanding the role of incentives in network security and modeling learning and adoption in social networks.
Ivan Canay’s research is in econometric theory, with specific interests in developing tests for assessing models that are partially identified. His most recent work includes methods for inference on individual components of parameters defined by moment inequalities, inference in models with few clusters via randomization tests, and inference under covariate adaptive randomization. He is currently an associate editor of the Journal of Econometrics, the Journal of Business and Economic Statistics, and the Econometrics Journal.

Ozan Candogan is an Associate Professor of Operations Management at Chicago Booth. Prior to joining Booth, he was an Assistant Professor at the Fuqua School of Business where he was a member of the Decision Sciences area. He received his Ph.D. and M.S. degrees in Electrical Engineering and Computer Science from the Massachusetts Institute of Technology.
Professor Candogan’s research is primarily motivated by the role that social and economic networks play in different operational settings. It has three complementary branches:
(i) Impact of networks on operational decisions.
(ii) Complex social and economic systems and new methodologies.
(iii) Pricing and revenue management problems in service systems.
Ozan Candogan was a finalist in the 2013 George Nicholson Student Paper Competition. He is also a recipient of the 2012 Microsoft Research Ph.D. Fellowship, and 2009 Siebel Scholarship. He teaches Operations Management, as well as a PhD course on Networks at Booth.

Chao Gao’s research interests are spread across nonparametric and high-dimensional statistics, network analysis, Bayes theory and robust statistics.
Dongning Guo’s research interests lie in communications, networking, information theory, and signal processing. His current projects concern next generation cellular networks, the Internet of Things, information theory of many-user systems, millimeter wave and full-duplex communication, as well as experimentation using software-defined radios. Dongning received his Master’s and Ph.D. in Electrical Engineering from Princeton University.

Prof. Hartline’s research introduces design and analysis methodologies from computer science to understand and improve outcomes of economic systems. Optimal behavior and outcomes in complex environments are complex and, therefore, should not be expected; instead, the theory of approximation can show that simple and natural behaviors are approximately optimal in complex environments. This approach is applied to auction theory and mechanism design in his graduate textbook Mechanism Design and Approximation (http://www.jasonhartline.com/MDnA/) which is under preparation.
Joel Horowitz’s research is concerned with estimation and inference under weak assumptions about the process that generates the available data. It is also concerned with improving the accuracy of inference with samples of practical size and with using shape restrictions provided by economic theory to improve estimation and inference. He is a former co-editor of Econometrica and Econometric Theory, a Fellow of the Econometric Society and of the American Statistical Association, and an elected member of the International Statistical Institute.
Samir Khuller is chair and Peter and Adrienne Barris Professor in the Department of Computer-Science at Northwestern University. Prior to joining Northwestern’s newly-established department of computer science in March 2019, Khuller spent twenty-nine years at the University of Maryland College Park where he held the Elizabeth Stevinson Iribe Chair, and spearheaded the development of the Brendan Iribe Center for Computer Science and Engineering.
Khuller’s research interests are centered on graph algorithms, discrete optimization and computational geometry. He has published over 200 journal and conference papers as well as book chapters on these topics. He is a recipient of the National Science Foundation’s Career Development Award, a Google Research Award as well as the University of Maryland’s Distinguished Scholar Teacher Award. In 2016, his work on Connected Dominating Sets (with Sudipto Guha) received the European Symposium on Algorithms inaugural Test of Time Award.
Khuller has served as editor for several journals including Algorithmica, the International Journal on Foundations of Computer Science and Networks. He has also served on numerous program committees including SODA 1997, APPROX 1999, APPROX 2000 (chair), STOC 2003, PODS 2006, SODA 2007, APPROX 2010, ESA 2010, STOC 2013, SPAA 2017. A member of the ESA Steering Committee (2012-2016), he chaired the 2019 MAPSP Scheduling Workshop and will serve as the Chair of SIGACT from 2018-2021.
Khuller received his M.S and Ph.D from Cornell University in 1989 and 1990, respectively, under the supervision of Vijay Vazirani. His completed his undergraduate degree in computer science at the Indian Institute of Technology (Kanpur) in 1986.

Yury Makarychev received his MS degree in Mathematics from Moscow State University in 2001 and his PhD degree in Computer Science from Princeton University in 2008. He spent the following two years as a Postdoctoral Researcher at Microsoft Research in Redmond, WA and Cambridge, MA.
Yury’s research interests include combinatorial optimization, approximation algorithms, semi-definite programming, and low-distortion metric embedding. He has recently worked on developing approximation algorithms for unique games, constraint satisfaction, graph partitioning, and vertex ordering problems, investigating tradeoffs between local and global properties of metric spaces, and studying lift-and-project hierarchies of mathematical relaxations.
