Young Transiting Planets
While thousands of exoplanets are known, most orbit field stars with poorly measured ages between 1 and 10 billion years. I have been using TESS to find and characterize planets around stars in open clusters and moving groups younger than 1 billion years. Related articles include:

Long-term Fates of Hot Jupiters
Tides are expected to cause hot Jupiters to inspiral into their stars and be torn apart, but it is not clear how long this takes. Beyond determining the lifespan of hot Jupiters, the answer also has implications for whether the Earth will be consumed by the Sun in the distant future. Related contributions:

Design and Analysis of Transit Surveys
I’m broadly interested in the design, execution, and analysis of planet-hunting surveys, particularly using the transit method. Related studies include:
