Bruce G. Elmegreen
Dr. Bruce Elmegreen works in the Physical
Sciences Department of the Research Division of
IBM. His main interests in astrophysics include
star formation, interstellar matter, and galactic
structure. Through a combination of observations,
analysis, and computer modeling, he has proposed
and developed models for triggered and spontaneous
star formation processes in normal galaxy disks.
With Debra Elmegreen
and Magnus Thomasson,
he demonstrated the existence of standing spiral
wave patterns in galaxies, and was among the first
to measure their speeds. His recent work on hierarchical
structure in turbulent gas has applications to long-standing
problems on the mass distributions and spatial arrangements
of interstellar clouds and the stars they form.
Bruce Elmegreen joined IBM in 1984 after holding
a faculty position at Columbia University. He received
his Ph.D. at Princeton University under the guidance
of the late Lyman Spitzer, Jr., and then spent three
years as a Junior Fellow at Harvard. He was raised
in Milwaukee, and attended the University of Wisconsin
as an undergraduate.
