Justin Crepp


Justin Crepp, an astrophysicist and the Frank M. Freimann Professor of Physics, joined Notre Dame after receiving his Ph.D. at the University of Florida in 2008. Crepp is the recipient of the 2013 NASA Early Career Award and was recently named by NASA as a member of the Transiting Exoplanet Survey Satellite (TESS) science team, which discovers exoplanets orbiting the stars across the known universe.

Crepp’s research is specifically interested in the detection of faint substellar companions that orbit nearby stars. To this end, he currently leads an observing program called “TRENDS” that is able to combine state-of-the-art techniques to measure the mass of those objects. Additionally, he is also working on a new instrument called “iLocator.” iLocator, an ultra-precise planet-finding spectrometer, will search for planets that have those characteristics that might enable them to foster life, and will study what those characteristics are.

This professorship was established with earnings from a gift of the Freimann Charitable Trust, made in honor of Frank Freimann, a pioneer of the electronics industry and former chief executive officer of Magnavox. There are 11 Freimann professors at Notre Dame, all in engineering and physics.
