Soumendra Lahiri is a Professor of Statistics at the North Carolina State University. His research interests include Nonparametric Statistics, Time Series, Spatial Statistics, and Statistical inference for high dimensional data. He served as an Editor of Sankhya, Series A (2007-2009) and currently, he is on the editorial boards of the Annals of Statistics and the Journal of Statistical Planning and Inference. He is a fellow of the ASA and the IMS, and an elected member of the International Statistical Institute.Anton Schick is Professor and Chair of the Department of Mathematical Sciences at Binghamton University. His research interests include semiparametric efficiency, U-statistics, empirical likelihood, residual-based inference, incomplete data, curve estimation, and inference for stochastic processes. He currently serves on the editorial boards of Statistics and Probability Letters, Statistical Inference for Stochastic Processes, and the Journal of the Indian Statistical Association.Ashis SenGupta is Professor (HAG), at Indian Statistical Institute, Kolkata. His research interests are in Multivariate Analysis and Inference, Probability distributions on manifolds, Directional Statistics, Reliability and Environmental Statistics. He has been a frequent vistor to several universities in USA as a visiting faculty including Stanford University; University of Wisconsin - Madison; University of California - Santa Barabara and Riverside; and Michigan State University-East Lansing. He is an Editor-in-Chief of Environmental & Ecological Statistics, Springer, USA, and an Editor of Scientiae Mathematicae Japonicae, Japan. He has been President of International Indian Statistical Association (India Chapter) for several successive terms. He is a Member of the Project Advisory Committee - Math. Sciences, DST, Government of India; a Fellow of National Academy of Sciences, India and a Fellow of American StatisticalAssociation, USAT. N. Sriram is currently a Professor at the Department of Statistics, University of Georgia (UGA). He is a Fellow of the American Statistical Association and the winner of Special Sandy Beaver Teaching Award at UGA. His research interests focus on theory and applications for a variety of statistical scenarios, such as sequential analysis for independent & dependent data; bootstrap methods for linear & non-linear time series, and branching processes; robust estimation methods for mixture models; dimension reduction methods and its robust modifications in time series and in association studies; and sample size determination for classifiers arising in biological studies. His research has been funded by federal agencies such as National Science Foundation, National Security Agency, and the Bureau of Labor Statistics. He has directed eleven doctoral dissertations, served as an editorial board member of three statistics journals, organized three international conferences, and served on NSF panels.
