Background

 

I was a student at Saddleback College in the early 1980s. I started out as an Art major and considered studying Philosophy, Political Science, and Environmental Studies before discovering and falling in love with Geology.

 

I earned an AB in Geology from UC Berkeley in 1991, then moved on to graduate school at UC Santa Cruz. My dissertation was a study of the effects of cyclic changes in past climate on landscape evolution in southern Utah.

 

In addition to field work, this project required a detailed understanding of climate forcing mechanisms and buffers and how they interact with one another. I also had to understand and apply radiometric dating techniques.

 

Teaching

 

I teach courses that interest me. I don't know everything about every topic covered, but I try to stay current on everything by reading a lot. I find that, if I'm doing my job well, students come up with fascinating and challenging questions.

 

Although many of the courses I teach cover general topics, I don't recycle lectures -- every semester I spend a significant amount of time sorting through and rewriting all of my notes to keep things current and interesting.

 

In addition to geology, I teach a couple of astronomy classes each term, one general astronomy and one class on the geology of the planets. I also co-teach a Humanities class about the co-evolution of science and modern culture.
