My scientific training was with Dr. Michael A. Savageau (Member, Institute of Medicine of the US National Academies and Distinguished Professor) (PhD thesis work), Dr. Alan S. Perelson (Fellow, American Academy of Arts and Sciences and Senior Laboratory Fellow) (postdoctoral work), and Dr. Byron Goldstein (Laboratory Fellow) (postdoctoral work), who introduced me to the cell signaling problem, which I have worked on since. My primary appointment is in the Theoretical Biology and Biophysics Group of the Theoretical Division at Los Alamos National Laboratory. I am also affiliated with the Department of Biology and the Cancer Center at the University of New Mexico. My research interests relate to modeling biological systems, especially cellular regulatory networks involved in cancer and/or immunity. I am also interested in developing advanced methods and software to support modeling in cell and molecular biology and uses of multivariate statistics and machine learning to analyze biological data.
