ORG Dartmouth College Title BIO David M. Nicol, Professor of Computer Science at Dartmouth, is one of the Technical Program Coordinators at the Institute for Security Technology Studies. His research interests have focused on high performance computing, on performance analysis, and on simulation of large-scale computing networks. He is co-architect of a networking simulation system capable of simulating in near-real time very large communication networks. His recent work uses this system to explore the performance and ramification of technologies used to make networks secure from hostile attack. His simulation work is a key enabling technology for research in secure networking. Nicol received his B.A. in mathematics from Carleton College in 1979 and his Ph.D. in computer science from the University of Virginia in 1985. After working as a staff scientist at the Institute for Computer Applications in Science and Engineering at NASA Langley Research Center, he joined the faculty at the College of William and Mary, where he was awarded the William and Mary Alumni Fellowship for Excellence in Teaching. He joined Dartmouth in 1995. He has published over 120 articles in leading journals and conferences and has served as consultant to NASA, IBM, AT&T Bell Labs, and Sandia National Laboratories. Editor-in-Chief of the ACM journal Transactions on Modeling and Computer Simulation, he has also served on the editorial board of the INFORMS Journal on Computing.
