I am the George Ellery Hale Distinguished Scholar (= “tenure-track” Research Scientist) at Carnegie Observatories. My research broadly focuses on understanding the life stories of exoplanets. Currently, the major efforts I am leading include:

• The WINERED Helium Consortium (PI), a group of researchers from Carnegie, Harvard, MIT, Chicago, and STScI trying to understand atmospheric loss in sub-Neptune-sized exoplanets using Magellan/WINERED observations of the metastable helium triplet (He*).

• STELa (the Search for Transiting Exoplanets in Lyman-alpha; Co-PI), an HST multi-cycle treasury program (625 orbits over 3 years) that aims to constrain atmospheric loss in the nearest transiting exoplanets using the Lyman-alpha line of neutral hydrogen.

• TUNES (The Unintentional NIRISS Escape Survey; PI), an archival JWST/NIRISS program which will constrain planetary outflow structures in dozens of planets using He*.

• The Hot Neptune Initiative (Co-PI), which aims to discover and measure the masses of some of the best Neptune-sized exoplanets for atmospheric characterization using a wide array of high-resolution spectrographs.

There are a number of other projects I am also excited about, including the studies of tidal decay, studies of the Neptune desert (from both atmospheric escape and demographics angles), lower and upper atmospheric constraints in temperate planets, instrumentation for ultra-high-resolution spectroscopy, automated methods for exoplanet atmosphere detection, constraints on atmospheric isotope ratios, and others.

I am actively looking to grow my research group. If any of the above sounds interesting and you are interested in joining, please send me an email.
