Thushara Perera


Associate Professor of Physics

B.A., Ohio Wesleyan University; M.Sc., Ph.D., Case Western University

Professor Perera's research is focused on cryogenic instrumentation for detectig and studying light at teratertz frequencies (or millimeter wavelengths).   He uses those technologies to study how grains of cosmic dust--or analogs to them--interact with light.  Results from his lab investigations can then aid with the interpretation astronomical data on dusty objects/environments in space such as stellar "nurseries," newly formed planetary systems (i.e. new solar systems), and distant "starburst" galaxies.

As a graduate student, Perera worked on detecting dark matter using novel supercondcting and semiconductor-based detectors.  As a postdoctoral researcher, first at the University of Chicago and then at the University of Massachusetts Amherst, Perera developed and used superconducting and semiconductor technologies for mm-wave observations of the oldest structures in the universe, such as massive early galaxies and the primordial glow from the big bang, known as the cosmic microwave background (CMB).
