Greetings. Since I moved to Wisconsin in part for the cold, snowy winters it's supposed to have, perhaps it's appropriate that I'm also drawn to ice for scientific study. More specifically, ice clouds. I have experience in remote sensing of cloud properties, but currently I'm working on modeling heterogeneous ice chemistry. I'd like to know how the gunk we put in the air is affecting our climate in an insidious way--by affecting the vertical distribution of water vapor high in the atmosphere, in the upper troposphere and lower stratosphere. This could be important because water vapor is a very effective greenhouse gas, and its distribution (and phase) is important in understanding climate change.

If you'd like to hear more about my research, you're welcome to email me at

My C.V. has a little more to add, in terms of science work. Other work involves teaching here, and sometimes involves ice cream.

Join me for this year's Horribly Hilly Hundreds. Mwa ha ha.
