This research investigates how exoplanets form by analyzing the chemical fingerprints of their host stars. Using stellar abundances and galactic archaeology, the work explores how rocky material shapes planetary systems, whether stars consume planets, and how common Earth-like worlds may be throughout the Milky Way.

This research investigates the origins of cosmic dust, a critical ingredient for stars, planets, and life. Using infrared observations of massive stellar explosions through the Red Astronomical Transient Survey, the study shows that massive stars produce significant amounts of both silicate and carbon-rich dust, shaping galaxy evolution and early planet formation.

This research investigates whether dark energy, responsible for the universe’s accelerating expansion, evolves over time rather than remaining constant. Using galaxy distributions, supernovae, and cosmic microwave data, new statistical methods suggest evolving models may better fit observations, potentially reshaping our understanding of cosmology and the universe’s long-term fate.

This research investigates “zombie stars” — reanimated white dwarf systems formed through stellar interactions in binary star systems. By analyzing large-scale brightness variations across the Milky Way, the work identified hundreds of these rare objects, providing new insights into stellar evolution, galactic history, and the future lifecycle of stars in our universe.
