Research Interests

Gamma-ray Bursts and Counterparts, X-Ray Astronomy, Gamma-Ray Astronomy
Analysis of data from and operations of the Swift MIDEX mission.
Development of InFOCuS balloon instrument.

Current Projects

Analysis 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.
