Attempt at a depiction of gravitoelectromagnetism from a 2015 article in a special issue of Classical and Quantum Gravity devoted to the Gravity Probe B experiment. (Many thanks to computer artist and game designer Pancho Eekels for his help in creating this image)

My research focuses on the interface between gravitation, cosmology, astro- and particle physics. These are developing fields where we do not yet know all the answers. They are places in which theoretical speculation used to run rampant, but is now increasingly checked by experiment and observation. And the questions could not be more important. Some recent investigations:

Much of this research involves students. If you are an undergraduate student or potential high school intern, and interested in learning about subjects like the above, you are welcome to look at my list of ongoing opportunities for new research projects and talk to me, ideally in person.
