The focus of my research is extremal graph theory and random combinatorial structures. I have also worked in a variety of other areas, including intersecting hypergraphs, the theory of positional games and Ramsey theory. Combinatorics, and particularly graph theory, has a wide variety of applications. My own research in the edit distance of graphs has applications in biology and computer scienc...

MICHAEL J. PELSMAJER Brief Research Summary (October 2007)

Mostly I study graph theory: sometimes more as mathematics (structural, extremal) and sometimes more as computer science (algorithms, complexity), although one often helps with the other, and I have interests (graph drawing, tree-width) that fall squarely in the middle of of the two fields. As for topics, I have not particularly specialized or restricted the types of problems I work on. Rather,...

HEMOSTATIC ALTERATIONS FOLLOWING SEVERE DYSBARIC STRESS by Michael J. Jacey

Hemostatic parameters were measured in the blood of mature Sprague-Dawley rats during a three day period following exposure to a compression-decompression schedule designed to produce severe dy sbaric stress. The animals were compressed on air to a pressure equivalent to 300 feet of sea water for 30 minutes and stage decompression over a 42 minute interval. Acute decompression stress produced a...
