Hydrology - Water Resources - Ecosystems - Environment
I look to better understand the global water cycle including its relation to human activity, the environment, and the earth system.

I have been fortunate to be involved in teaching at many levels throuhgout my academic career. Below I detail the university level courses I have been involved with. In addition to the courses I have received formal tutoring training from the Cal State System and taken a course in curiculum development and engaged learning from the University of California.
Welcome to my site. I am currently a postdoctoral scholar in the Carbon and Ecosystems Group at the NASA Jet Propulsion Laboratory.
My contact information is listed at the top my CV. Contact me if you see an oportunity to colaborate or to chat science, education, or adventures.
