Research

Applying modern computational algorithms and statistical inference methods to accelerate astrophysical discovery - across three primary research areas (the Sun, stars, and exoplanets) and one minor area in terrestrial geophysics.

Transit photometry & RV

Characterization of planetary candidates

Characterizing planetary candidates them from transit light curves and radial-velocity signals

Asteroseismology

Stars

Measuring stellar structure, rotation, and evolution from photometric variability in Kepler and TESS data.

Helioseismology

The Sun

Imaging flows, magnetic fields, and convection in the solar interior using acoustic oscillations.

A minor research area

Earth

· Geophysics

Applying seismic-inversion techniques developed for the Sun to terrestrial geophysics — a secondary research area.
