Research Interests

Prof. Lauren M. Weiss is a member of the Astrophysics group. She uses observational techniques to discover planets around other stars (exoplanets) and characterize their fundamental properties, with the goals of (1) understanding the origin and evolution of planetary systems, and (2) assessing exoplanet habitability. 

Professor Weiss’ research highlights include:

  • Discovered the distinction between planets with rocky surfaces and gas envelopes at 1.5 Earth radii
  • Discovered the similar sizes and regular spacings of planets in coplanar multi-planet systems (the "peas in a pod" pattern)
  • Principal Investigator of a NASA/U. Hawaii Key Strategic Mission Support program at Keck Observatory to study the diversity of planet interiors in multi-planet systems
  • A senior member of the Keck Planet Hunters/California Planet Search collaboration.
