Office Hours:
by appointment

I was born and raised outside of Munich, Germany and moved to the US in 2005. Since then I've studied geology at three different institutions and I'm currently in my third year of the PhD program in the Department of Geology. I've always loved to teach (since my undergraduate days) and I am pursuing a academic career. Currently, I am a research assistant for Dr. Klimczak and I am looking forward to teaching in the Fall of 2018.

Research Interests:

I'm interested in tectonic geomorphology and structure pertaining (but not limited to) the evolution of faults. I am interested how faults propagate and what type of structures result from fault interaction and linkage. I've been exploring displacement-length relationships for graben-bounding normal faults on the Moon and am preparing to do the same for faults in the graben of Canyonlands National Park. I'm also interested in the use of Unmanned Aircraft Systems (UAS) as an additional method to collect data and present results in new and innovative 3D models.
