I have been studying planetary science since 1978. For my dissertation research, I analyzed the ultraviolet spectra of comets obtained with the NASA/ESA International Ultraviolet Expllorer (IUE) satellite. In the 1980s, I started observing comets using high resolution infrared spectroscopy, and discovered water emission from Comet Halley in 1985 using the Kuiper Airborne Observatory. I've led many investigations of comets using the NASA/ESA Hubble Space Telescope (HST). I was the Principal Investigator on the first HST spectroscopic observations of a comet in September 1991, and on the main HST program to study Comet D/Shoemaker-Levy 9, which plunged into Jupiter’s atmosphere in July 1994. I led several programs to observe comets using the Far Ultraviolet Spectroscopic Explorer (FUSE), another Earth-orbiting astronomical facility. In 2007, I became a Co-Investigator on the Alice Ultraviolet Spectrograph, which is one of the principal NASA contributions to the ESA-led Rosetta comet mission. Currently I'm a Co-Investigator and Project Scientist on the New Horizons Mission, the first spacecraft mission to Pluto and the Kuiper belt. In 2005 my team and I discovered two new satellites around Pluto, Nix and Hydra. In summer 2015 New Horizons passed by Pluto, turning it from a pixelated blob into a complex and diverse world with water ice mountains, nitrogen glaciers, and multiple layers of atmospheric haze. Asteroid 5720 Halweaver was named after me in 1996.
