I study the Milky Way galaxy to find out how and why it evolved to its present state.
I research the violent and capricious nature of the universe. I use computer simulations to explore transient phenomena such as collisions, mergers, and disruptions of stars—especially those involving compact objects.
My research examines the nature of gas both within and outside of galaxies, primarily during the first few billion years of the universe.
My current research interests have focused on theoretical cosmology and the high-redshift universe, especially on the physics of the intergalactic medium and the history of star formation in galaxies.
The core of my research focuses on understanding the co-evolution between dark matter and galaxy formation.
My research is focused on the formation and evolution of galaxies—specifically, their accretion/cannibalism history, dark matter content, chemical enrichment, and star formation history.
I use telescopes to discover and characterize astrophysical transients such as supernovae, gravitational wave events, and other exploding stars.
I conduct research in theoretical physics, especially elementary particle physics, astrophysics and cosmology. Work includes studies of the Standard Model and Physics Beyond, cosmic inflation, dark matter and dark energy.
I study the formation, nature, and evolution of the universe, focusing primarily on the model of eternal inflation and what it means for the beginning of the universe and time.
My research focuses on observational cosmology and particle astrophysics, including constraints on the nature of dark matter and dark energy and studies of the evolution of galaxies.
I investigate new physics beyond the Standard Model with a focus on dark matter, baryogenesis, and new particles and their interactions.
My current interests include dark energy studies using weak lensing and searches for signatures of dark matter.
