Our goal is to find and study exoplanets, which are planets orbiting nearby stars. As astronomers, we have come up with clever ways to study their properties. This allows us to explore nearby worlds from the comfort of our home planet! One of my group’s long-term goals is to characterize more small rocky planets like the Earth. This information will help us to determine whether or not a given planet might be able to support life, and (eventually) to look for evidence of life on those planets.

I’m working on the Planet Nine Hypothesis, a proposed world lurking on the fringes of our solar system. Since antiquity, humanity has only discovered two true planets beyond those known to the ancients: Uranus and Neptune. If Planet Nine exists, it will expand our census of worlds in the solar system and, with its immense orbit, hold a fossil record of the solar system’s earliest days. Understanding it would not only reshape our map of the nearby cosmos but also reveal how planets form and migrate. The Vera Rubin Observatory comes online later this year. Its sweeping sky survey will put decades of theory to the test. It may confirm or refute our predictions, uncover new patterns, or even detect Planet Nine directly. Either way, we stand at the threshold of discovery.

We are researching people’s responses to the phone alerts sent out during the 2025 LA wildfires to improve earthquake early warning alerts. We want to find out if people ignore alerts or want more as time passes. We hope to understand decision making and how people respond during emergencies. Millions of people have already been alerted during smaller "one-off" earthquakes, but a large earthquake will have many aftershocks over many days. This research will inform how earthquake alerting happens during aftershocks.
