I study near-Earth supernovae, i.e. supernovae which occur withing 10 - 300 pc of Earth (anything closer puts Earth in the "kill zone", which means we would not be around to study it). Currently, we have evidence of two near-Earth supernovae that have happened over the last 10 million years - the data for which comes from a radioactive isotope (60Fe, t1/2 = 2.6 Myr) found in ocean sediment cores!
As of Spring 2018, I am working with Professor Brian Fields on modeling interactions between supernovae-produced dust and magnetized supernovae remnants. This is of particular interest, since this dust is what delivers the 60Fe to Earth, and is therefore directly linked to the actual data.
