I grew up just outside of Boulder, CO with two great parents, 9 brothers and sisters, and an outdated New World Book of Knowledge set of encyclopedias. Somewhere between skateboarding and making drugs at a local pharmaceutical company, I developed a deep appreciation for chemistry, and for the sciences in general. I am particularly fascinated by the interesting things that happen at interfaces in really small (submicron) systems. Interfacial issues are critical to developing useful nanotechnologies. In order to put synthetic molecular machines to work, we need to develop ways of incorporating them into devices and then making sure they are doing what we think they are doing. Currently, I’m developing strategies for efficient attachment of molecular machines to solid surfaces and the means to characterize the action of these exotic molecules at interfaces.

In my spare time, I enjoy hanging out with my wife and three kids. If there's any time left after that, I try and spend it in some of the nearby forest preserves on a mountain bike.
