The research group is always changing as students and post-docs start and eventually finish research projects. Below you will find:
With my return from sabbatical, as of January 2019, we are in a group building phase. In February post-doc Menno Fraters (PhD, Utrecht University 2019) joined the group as a post-doctoral scholar. Menno is working on the development of Lattice-preferred orientation in simulations of subduction using the software code Aspect. Haoyuan Li and Becky Fildes joined in September as a new PhD students. Haoyuan completed his MS at Peking University with a project on the role of ilmenite in mantle convection on the moon. Becky Fildes has completed projects on caldera collapse seismicity at Kilauea (with Louise Kellogg as her advisor). I am continuing to recruit new graduate and undergraduate students to work on problems related to many different parts of the subduction dynamics problem.

Here is a recent resume with everything I’ve been up to billen_resume_prof (last updated June, 2021).
I can’t say that I always knew I’d be a geophysicist, but growing up in San Diego, I got the chance to feel a few earthquakes and wonder. I did my bachelor’s degree in physics at the University of Puget Sound and then decided geophysics would give me a chance to pursue the mechanics-type physics I really enjoyed. I did my PhD (1995-2001) at Caltech with Michael Gurnis, but I also worked with Joann Stock and Mark Simons. Following my PhD did two post-docs, first at the University of Leeds in England working with Dr. Greg Houseman (2001-2002), and then at Woods Hole Oceanographic Institute (WHOI) in Massachusetts working with Dr. Greg Hirth and Dr. Peter Kelemen (2002-2003).
I started my time at UC Davis as an assistant professor in 2003. I was promoted to associate professor in 2008 (tenure – yeah!!), and then to a full professor in 2015. I was also a visiting scholar at Northwestern University in 2009 and at LMU in Munich, Germany in 2016-2017.
I have also started three special projects outside of work:
The Lucas project started in 2011, followed by a twin project, Eliane and Sophie, starting in 2013. These on-going projects make me happy no matter which code is not working, whether I got funding for my last proposal or whether my last talk or lecture went as well as I’d hope. There’s a picture of the three little monsters below…
