I am a Senior Research Scientist with McDonald Observatory specializing in stellar astronomy. I have a B.Sc. (with distinction) from the University of Rochester and a M.S. and Ph.D from the University of Toronto. In 1970 I arrived at UT Austin as a McDonald Postdoctoral Fellow and never left. My interests in planetary science are more avocation than vocation. I have used that interest in teaching Introductory Astronomy and in teaching a course in Extraterrestrial Life.
