How I Got Here
I did not know that I was going to be a planetary scientist until halfway through
graduate school. As a kid I was pretty good at math and science, but also liked to run
around and play softball. I grew up in Colorado, first in Littleton (near Denver) then in
Douglas County, which in the late '70s was still mostly ranch land. I had a great physics
teacher in high school but also was very active in drama classes and school plays. When I
got to college at the University of Denver, I didn't know whether I should major in physics
or theater, but in the end I figured I'd get a better job as a physics major. I ended up
with a minor in geology because I thought field trips were loads of fun. I still remember
the first fossil I found: I was in sixth grade when we went on a class trip to a place
that had lots of shale (clay that has been compressed into rock) and I came home with a
shark tooth! I still have that tooth, and later found out the shark's name, tychodys, a
creature that ate shells millions of years ago.
In addition to enjoying being outside whenever possible, I also really liked
my physics lab classes. After I earned my Bachelor's degree I needed some time
off so I went to work for Ball Aerospace. There I did lab tests on silicon chips
(called CCDs) that take pictures from space, characterizing how well they
measured light in different colors. After working for two years I was ready to go
back to school and the Univ. of Colorado was right there in Boulder so I started
taking physics classes. After a year I knew physics was not for me and switched
to geophysics. Eventually, I started research in remote sensing, looking at other
planets from far away. I've been doing that for 10 years, gradually refining my
"specialty" and getting a Ph.D. in 1991. I had a research fellowship and spent a
year in northern Germany, which was too rainy and flat. I jumped at the chance to
come back to the western United States and have been in Flagstaff for four years.
