I received my Ph.D. in elementary particle physics, but have since moved into astrophysics (anisotropy of the cosmic microwave background; supernovae for cosmology) and geophysics (origin of the earth's magnetic flips, Nemesis theory, glacial cycles, astrophysical effects on evolution) . Some of the most fascinating questions of science lie not on the extremes of our ability to probe, but in the cracks between well-studied disciplines. I prefer experimental work, but will do theory when it is needed.

Current Projects

Gordon MacDonald and I published a technical book titled "The Ice Ages and their Astronomical Origins" in 2000. The origin of the 100 kyr cycle of glaciation is not understood.

In March 2005, graduate student Robert Rohde and I published an article in Nature reporting the discovery of an unexplained 62 million-year cycle in the diversity of fossil genera.

We are currently working on a paper that explores the linkage between solar activity and Earth cloud cover.

We have also submitted a paper describing our measurements of the ages of over 100 lunar craters, done in collaboration with the Berkeley Geochronology Center.
