PhD, 1983, University of Maryland
Dr. Dave Schleicher’s major research interests include the physical properties, chemical composition, and behavior of comets. He uses a variety of observational tools plus theoretical modeling in his studies. In 1986, Schleicher discovered with Dr. Robert Millis the periodic variability of Comet Halley — a discovery that profoundly affected the interpretation of all observations of the comet including those from the Giotto and Vega craft. Dr. Schleicher is also an accomplished photographer.
