Research Interests

Asteroid (near-Earth, main belt, Trojan) surface properties; shapes, sizes, spin states. Find out more on my research page. In short, I really like rocks: now that I get to zap space potatoes with 20 terawatts of 2.38 gigahertz radar my life is pretty swell. I have a tiny meteorite collection as well.
Polarization ratio versus absolute magnitude, as well as taxonomic class, of 299 near-Earth asteroids observed with planetary radar.

... though in the past I've worked on ices and the process of icing; asteroid-comet crossover objects; potentially-hazardous asteroid spectra; Pluto and its posse of Kuiper Belt objects; in situ exploration via spacecraft; mission design and management; rings; and moons in the outer solar system. There was a brief period where I even worked on extragalactic radio jets. I even like isotope geochemistry on alternate Tuesdays. And I'd be pleased as punch to get into atmospheric work.

Quotes Astronomical

"No one in his proper senses can ascribe the slightest use to the existence of comets. For ages they have served no other conceivable "purpose" than to frighten people out of their wits." --Woolsey Teller

Night Vnto Night Showeth Knowledge

"Astronomy compels the soul to look upwards and leads us from this world to another." --Plato

"I know nothing of any certainty, but the sight of stars makes me dream." --Vincent van Gogh

"Research is formalized curiosity. It is poking and prying with a purpose. --Zora Neale Hurston
