Bio

Dr. Patrick Durrell is a Distinguished Professor of Physics and Astronomy at Youngstown State University and was recently (2021) named the first Warren M. Young Chair of Physics and Astronomy through his work as Director of YSU’s Ward Beecher Planetarium. Dr. Durrell actively conducts research (as part of numerous international scientific collaborations) on stars and star clusters in nearby galaxies using data from some of the largest telescopes in the world, including the Hubble Space Telescope. Dr. Durrell has been at YSU since 2004, and has been Director of the Ward Beecher Planetarium for most of the 18 years after his arrival.

Research Interests

A varied number of topics in observational astronomy, using data from both large ground-based telescopes and the Hubble Space Telescope. My interests include
- photometric studies of globular clusters, both in our own Milky Way galaxy and in other galaxies.
- photometric studies/surveys of dwarf galaxies, including dwarf elliptical, ultra-compact-dwarfs, and ultra-diffuse galaxies.
- resolved stellar populations in nearby galaxies, including using the Tip of the Red-Giant Branch (TRGB) as both a distance indicator and as a way to study the stellar populations in dwarf galaxies and galactic halos.
- intracluster red giant stars and globular clusters
- photometric studies of interacting/merging galaxies

Teaching Interests

Astronomy/Astrophysics at all levels (undergraduate, general public, graduate level). Including introductory astronomy, introductory planetary science, undergraduate astrophysics, observational techniques and data reduction methods.

Patrick Durrell Professor of Astronomy

Patrick Durrell is an astronomer and Distinguished Professor in the Department of Physics & Astronomy, and is also the Director of the Ward Beecher Planetarium.

Dr. Durrell’s research involves studies of the formation of galaxies through photometric studies of stars and globular clusters both within and outside of galaxies, making use of imaging data from the Hubble Space Telescope and other large ground-based telescopes, including the Canada-France-Hawaii Telescope. Specific research includes:

  • The distribution and chemical composition of globular clusters surrounding galaxies, as well as searching for globular clusters that lie in the space between the galaxies.
  • Intracluster stars – stars that formed within galaxies, but have since been gravitationally extracted from galaxies, and are now part of intergalactic space.
  • Photometric studies of stars and star clusters of colliding galaxies and in dwarf galaxies in nearby galaxy groups and clusters.
  • Stellar populations of nearby galaxies (eg. M81, M101, M31), specifically the luminous red-giant populations in these galaxies, in order to look at the formation and subsequent evolution of these galaxies.
  • Searching for dwarf galaxies and extremely low-surface-brightness (LSB) galaxies in nearby galaxy clusters. Dr. Durrell has been a part of the massive NGVS (Next Generation Virgo Cluster Survey) project since 2009, and the MATLAS project since 2012.

He is also actively involved in science outreach through YSU’s Ward Beecher Planetarium, and through CosmoQuest. He is also interested in incorporating recent astronomical data into the fulldome, immersive environment of planetariums.

Dr. Durrell received his PhD in Physics in 1996 from McMaster University, in Hamilton, Ontario. He held postdoctoral and teaching positions at the University of Waterloo, Case Western Reserve University, the University of British Columbia, and Penn State University, before coming to YSU in 2004.
