I lead many efforts to improve the increasingly complex science operations and planning at Swift, and in 2010 my efforts were recognized when I was promoted to Lead the Swift Science Operations Team.

I have been a co-investigator on the proposal of future missions to NASA, including Explorer and SMEX submissions of the JANUS concept, the XTiDE SMEX concept, as well as sounding rocket and cubesat proposals. Currently I am a Co-I of the Nimble SMEX mission proposal, where I led the Ground section of the proposal.

My research interests are mainly in the area of high energy astrophysics, and I have published papers on X-rays from Symbiotic Stars, X-ray Binaries, Magnetars, and many other (mostly Galactic) topics. I lead the US Swift effort on finding EM counterparts of Gravitational Wave sources with Swift.
