Sajal K. Das received the BS degree in 1983 from Calcutta University, the MS degree in 1984 from Indian Institute of Science, Bangalore, and the PhD degree in 1988 from the University of Central Florida, Orlando, all in computer science. He is a professor of computer science and engineering and also the founding director of the Center for Research in Wireless Mobility and Networking (CReWMaN) at the University of Texas at Arlington. His current research interests include wireless mobile and sensor networks, mobile and pervasive computing, and grid computing. He has published more than 300 research papers in international journals and conferences. He is a recipent of Best Paper Awards in ACM MobiCom '99, ICOIN '01, ACM MSWiM '00, and ACM/IEEE PADS '97; UTA's Outstanding Faculty Research Award in computer science in 2001 and 2003; UTA's College of Engineering Research Excellence Award in 2003; and the University Award for Distinguished Record of Research in 2005. He is the coauthor of the book Smart Environments: Technology, Protocols and Applications (John Wiley, 2005). Dr. Das serves as the Editor-in-Chief of the Pervasive and Mobile Computing Journal ( PMC) and is also an associate editor of IEEE Transactions on Mobile Computing, ACM/Springer Wireless Networks, and the International Journal on Parallel and Emergent Distributed Systems ( IPEDS).

Timothy Davis received the PhD degree from the University of Illinois in 1989, in the Center for Supercomputing Research and Development (CSRD). Following a postdoctoral year at the European Center for Research and Advanced Training in Scientific Computing (CERFACS) in Toulouse, France, he held a faculty position at the University of Florida, where he is currently an associate professor in the Department of Computer and Information Science and Engineering. His research interests are in combinatorial scientific computing, numerical linear algebra, graph algorithms, and parallel computing. His core expertise is in sparse matrix algorithms, from theory to algorithms to library-quality code. His sparse solver (UMFPACK) is at the core of x = A\b in MATLAB when A is sparse and unsymmetric, and is the core sparse solver in Mathematica, and many other commercial and open-source packages. He is currently working on sequential and parallel direct sparse matrix solvers for circuit simulation problems and linear programming, including a high-performance sparse Cholesky factorization paackage that will become x = A\b when Ais symmetric.
