[Posted:  Friday, June 8, 2002 ]
It was recently announced that Dr. Griff Elder's National Science Foundation proposal, DMS-0201080 RUI: Galois Structures in Local Number Fields, has been funded. This three year $117,224 grant provides support for his theoretical research in Algebraic Number Theory, as well as support for a few strong undergraduate students to carry out research projects of their own. This summer, three of those students will participate in The Mathematics of Cryptology, a workshop organized by Dr. Carl Pomerance (Bell Labs) at MathFest 2002 in Burlington, Vermont. At the same time, Dr. Elder will be travelling to University of Exeter in England (for the first trip of his sabbatical) where he will work with his colleague Dr. Nigel Byott.
 
pin   NIH Grant for Drs. Jim Rogers and Jack Heidel
[Posted:  Friday, June 7, 2002 ]
Dr. Jim Rogers and Dr. Jack Heidel have been awarded a three year $450,000 grant by the National Institute of Health (NIH) for the project Attractors of Complex Signal Transduction Systems. The topic of study is using mathematical analysis to understand the structure and function of complex biochemical pathways. Specifically they will be creating a new Boolean model of three large, interconnected biochemical networks and then developing new mathematical tools for the exact analysis of the Boolean model. They will be looking for chaos and mathematical complexity in the model in order to determine how these phenomena might be involved in information processing in the living cell. The project falls into the overall category of cancer research as malfunctions in the biochemical networks involved in the study are commonly associated with cancer.
