I am a researcher at the
MIT Kavli Institute, working on the
Transiting Exoplanet Survey Satellite (TESS). I am especially interested in time domain astronomy and potential uses of TESS for extragalactic astrophysics.
I earned my PhD in Astronomy from the
Ohio State University.
My thesis work was focused on the continuum emission in Active Galactic Nuclei.
I did my undergraduate work at St. John's College in Sante Fe, NM, which is known for its unique great books program.
I am working with the TESS mission to discover small exoplanets around nearby bright stars. I will also use TESS to study extragalactic transient phenomena, such as supernovae, tidal disruption events, and exceptional AGN activity.
I use the "reverberation mapping" technique to explore the interior structures of active galactic nuclei (AGN).
AGN are too distant to be resolved with direct imaging. Instead, I search for variable flux signals and their corresponding "light echoes"—the echoes encode information about the AGN interior. The videos below discuss this in more detail.
The AGN phenomenon is interpreted as actively growing (accreting) super-massive black holes. My dissertation research was devoted to understanding the black hole's environment, in particular, the accretion flow and surrounding "broad line
region."
My introduction to time-domain astronomy was a search for new Cepheid stars in NGC 4258, a mega-maser galaxy used to anchor the extra-galactic distance scale.
I am also working on a program to obtain precise Cepheid distances to the nearest AGN, which have distances uncertain by factors of 2 or more.
