Bispectrum
The bispectrum is a time series analysis technique that was originally developed to study ocean waves. We can now apply this novel technique to X-ray time series to probe regions close to black holes!

Research Interests
My primary research is focused on X-ray binaries, where a compact object
such as a neutron star or black hole accretes material from a nearby companion star.
I work on applying a higher order time series analysis technique called the bispectrum
to Quasi Periodic Oscillations (QPOs) from X-ray binaries. By using this new (to astronomy!)
technique, we can learn a lot about the geometry of the regions close to the black hole
where the high energy X-rays originate.
Polarimetry
After nearly 40 years, we have a window into the world of X-ray polarimetry thanks to IXPE, and I am very excited to be leading their General Observer Facility.

Better Presenting
Being able to effectively communicate to a wide range of audiences is an important skill to have! I co-lead workshops at the annual meetings of the American Astronomical Society to help researchers of all levels improve their presenting skills.
