My research interests are astrophysical cosmology and applications of quantum field theory to the physics of elementary particles. Cosmology is now a well established branch of science thanks in great part to the astounding diversification of Astronomy in the last three decades into observations covering a very broad range of the electromagnetic spectrum. It is also a very exciting field of research due to its inherent intellectual appeal, the rapid progress allowed by a steady flow of observational data, and the promise of much more to come thanks to many new telescopes being built. My most recent work has been on clusters of galaxies (see ApJ 532(2000)206 and ApJ 538(2000)92) and gravitational lensing (see ApJ 533(2000)194 and ApJ 535(2000)555). On the particle physics side, my most recent research has been on some of the phenomenology expected in supersymmetric quantum field theories (see Phys. Lett. B377 (1996) 83). My work has been funded by the National Science Foundation, the University of Missouri System Research Board , and by Research Awards here at UM - St. Louis. Over the years, I have collaborated on a long-term basis with scientists from around the world to carry out my research. Most recently: John Ellis @ CERN (Geneva, Switzerland), Joel Primack @ UCSC (Santa Cruz, USA), and Leopoldo Infante & Hernán Quintana @ Universidad Católica (Santiago, Chile).
