Ryan Lang was an undergraduate and graduate student at MIT, earning an S.B. in electrical engineering (2002) and physics (2003), an M.Eng. in electrical engineering and computer science (2003), and a Ph.D. in physics (2009). He returned to MIT in 2019 to teach physics in the Concourse program. His research interests are in the areas of astrophysics and Einstein’s theory of general relativity. Since 2015, he has been a member of the LIGO Scientific Collaboration, an international team of researchers who search for gravitational-wave signals generated by extreme objects like neutron stars and black holes. Every January, he participates in the MIT Mystery Hunt, a weekend-long puzzle competition held on the MIT campus. During the rest of the year, he relaxes by spending time with family and friends, playing board games, following the Red Sox, and keeping up with his DVR.
