Working on the Swift and InFOCuS projects.Brief Bio7/05 -- present Senior Scientist, USRA and NASA Goddard Space Flight Center7/99 -- 7/05 Associate Research Scientist, USRA and NASA Goddard Space Flight Center 7/98 -- 7/99 Elliott Assistant Professor of Physics and Astronomy, Hampden-Sydney College. 7/94 -- 7/98 Assistant Professor of Physics and Astronomy, Hampden-Sydney College. 9/91 -- 7/94 Postdoctoral Associate, Massachusetts Institute of Technology. 9/84 -- 9/91 Research/Teaching Assistant, University of Chicago. 9/83 -- 9/84 Department Paraprofessional, The Colorado College. Educational BackgroundDec. 1991 Ph.D., Physics, The University of Chicago.Thesis title: "A Search for Point Sources of Ultra-High Energy Gamma Rays with an Emphasis on the Binary System Cygnus X-3" Thesis advisor: Professor James W. Cronin. June 1986 M.S., Physics, The University of Chicago. June 1983 B.A., Magna cum laude, Physics, The Colorado College. Research InterestsGamma-ray Bursts and Counterparts, X-Ray Astronomy, Gamma-Ray AstronomyAnalysis of data from and operations of the Swift MIDEX mission. Development of InFOCuS balloon instrument. Current ProjectsAnalysis of gamma-ray bursts (GRBs) and hard X-ray transient data from Swift.Maintain and improve the Swift/BAT hard X-ray transient monitor and maintain the public web site; publish the results. Participate in joint Swift GRB observations with ROTSE (as a co-investigator), Konus/WIND, Suzaku/WAM and GLAST. Participate, as an Associate Member of VERITAS, in multiwavelength blazar observing campaigns involving Swift/BAT. Work on various tasks required to prepare InFOC?S for its next balloon campaign.
