Dr. McDowell received a Ph. D from Columbia University in 1966. Following a two and one-half year post-doctoral appointment at the Swiss Federal Institute of Technology, he came to the University of Texas at Austin in 1969. Here he established a potassium-argon dating facility that has been in operation for about 30 years. This facility has been utilized extensively in collaborative geologic studies conducted both within and outside of the Department of Geological Sciences. It has also been critical to Dr. McDowell's long-term interest in the magmatic history of western Mexico and adjacent areas of the southwestern United States. In recent years, Dr. McDowell has expanded his interest to include utilizing U-Pb geochronology and isotope geochemistry to examine older magmatic arcs and the basement domains of northern Mexico, as described below. Dr. McDowell is currently retired.
