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).
