Highlights
Five talks on different parts of my work. All talks follow, newest first.
Mar 2026 · contributed talk, RAPID Response, Caltech
Fast images for real-time discovery
How Effortless, then called Fast IMCOM, can reconstruct Roman's undersampled images fast enough for time-domain science.
Apr 2026 · seminar, University of Michigan
Weak lensing cosmology with Roman
What Roman's High Latitude Imaging Survey can measure about the Universe, and the image reconstruction it depends on.
Oct 2025 · invited seminar, University of Pittsburgh
Testing stellar theory with red giants
Thousands of red giants from APOKASC-3 as tests of stellar models: the first dredge-up, the red giant branch bump, and the masses of luminous giants.
Oct 2025 · invited talk (online), Galactic Genesis Working Group, SDSS-V
More reliable masses for luminous giants
A new correction to the asteroseismic masses of luminous red giants, and how it changes their ages and the predicted first dredge-up.
