Academic Appointments

Adjunct Associate Professor and Senior Lecturer
Senior Scientist, SETI Institute

I am a materials engineer and a professor in Dartmouth’s Institute of Writing and Rhetoric, where I teach Writing 5 (Expository Writing), Writing 7 (First Year Seminar) and Writing 44 (Science and Technology Writing).

I have always been interested in pedagogy and have taught secondary school mathematics as well as undergraduate and graduate engineering. My scholarly research in the area of writing and rhetoric is in student use of digital portfolios to develop and communicate a sense of the self in the academic sphere.

My first year writing courses examine the intersection of sport, technology, and culture. The introduction of new technology and scientific understanding change sports, often threatening the ideals attributed to them—purity and the natural body, fairness or a level playing field, and success as the result of hard work. Students in The Machine in the Game examine how the resulting ethical dilemmas play out for athletes, regulatory bodies, the media, and fans.

My NSF and NASA funded research for the SETI Institute lies in the characterization of planetary ice and the development of instruments for the exploration of frozen environments. I have worked in both the Arctic and Antarctic, and am currently leading a team to develop a portable micro computed tomography system to be used on Mars’ north polar caps.

My experience in grant funded science and engineering informs my work with WRIT 44 students, who come from all scientific majors and work on communicating their science to funders, peers, and the public. I enjoy mentoring students and the opportunity to work with those at all stages of their college career.

In my spare time I am working on a graphic novel set two hundred years in the future.
