Christopher Kochanek

Christopher Kochanek is a Professor and Ohio Eminent Scholar in the Department of Astronomy at The Ohio State University, affiliated with the College of Arts and Sciences. His expertise lies in cosmology, gravitational lensing, and supernovae. He earned his Ph.D. from the California Institute of Technology (1989) and a B.A. from Cornell University (1985). His research focuses on using gravitational lensing to study dark energy, dark matter substructures, and quasar accretion disks. He pioneered time-domain astronomy, exploring variability in massive stars and quasars, and co-led the ASAS-SN project for all-sky supernova detection.

Key achievements include the Dannie Heineman Prize for Astrophysics (2020) and the AAS Beatrice M. Tinsley Prize (shared 2020). His work spans binary neutron star mergers, Milky Way mass estimation, and dust-obscured stellar explosions. Recent studies analyze supernova progenitors and long-term variability trends in transient events.

• Awards: Heineman Prize (2020), Tinsley Prize (2020)
• Grants & Projects: ASAS-SN collaboration with Prof. Stanek, dark energy constraints via lensing, and Milky Way dynamics.
• Labs/Teams: Active in the Ohio State Astronomy Instrumentation Group and ASAS-SN observatory network.
