Associate Research Professor of Geological Sciences and Quaternary Studies

Evolutionary Biology, siliceous micropaleontology


Background:

Ph.D.1973Columbia University


Current Research:

My interests are in three fields of study:

1. Evolutionary Biology, particularly the tempo and mode of evolution. I pursue the long continuous records of siliceous microfossils in deep-sea sediment cores to test hypotheses about the rate and timing of morphologic change - is it continual, continuous, or episodic; what does that tell us about the nature of evolution at and above the species level? I am also interested in the more purely philosophical questions of species individuality, and the ethical implications of evolutionary biology.

2. Siliceous Micropaleontology. The spatial and temporal distribution of siliceous microfossils (diatoms and radiolaria) in polar marine and nonmarine sediments and/or glacial ice is an independent indicator of paleo-oceanic and atmospheric circulation for the reconstruction of paleoclimatic conditions. My particular interest is in Greenland and Antarctica through the last glacial cycle.

3. Paleoclimatology. The spatial and temporal distribution of silicious microfossils in cores from polar ice sheets may be used as independent tests of hypotheses concerning paleo wind strength and direction.
