<h3>I'm an astrophysicist studying supermassive black holes by watching how they change over time. </h3>
<p>Using massive time-domain surveys, I search for supermassive black hole binaries and characterize AGN and quasar variability. I have a particular fondness for hypervariable targets, where the weirder the light curve, the better. Much of my work involves building fast, computationally inexpensive analysis pipelines to find them.</p>
