Jason Steffen

Assistant Professor of Physics and Astronomy
Expertise: Astronomy, Exoplanets, Cosmology, Dark matter and energy, Gravitation, General physics


Jason Steffen works in the field of exoplanets — planets that orbit distant stars. He has been a member of the science team for NASA's Kepler mission.  He continues to analyze data from that mission to understand the properties of planets and planetary systems. He also worked on projects related to dark matter, dark energy, and gravity.

Steffen is originally from Utah and attended graduate school in Seattle. Before coming to UNLV, he was the Lindheimer Fellow at Northwestern University and the Brinson Fellow at Fermilab outside of Chicago.

In addition to his work in astrophysics, he is known for the Steffen Method, a procedure to efficiently board passengers on an airplane.
