He then attended Princeton University where he received a National Science Foundation Graduate Fellowship and Princeton's Dodson Fellowship, completing his PhD in 1999 .
He then took a position as an Assistant Professor at the University of Texas at El Paso. In 2005 he moved to a position at Cornell University where he was a member of the Institute for the Study of the Continents, and a member of the faculty in the Department of Earth and Atmospheric Sciences and the American Indian Program. In 2012, Dr. Andronicos accepted a position as an Associate Professor at Purdue University in the Department of Earth, Atmospheric, and Planetary Sciences.
His research is focused on understanding high temperature deformation in the deep crust and upper mantle. He has focused his work on continental orogenic belts in the southwestern United States, western Canada, and the Tibetan plateau. He has recently begun work on the Oman Ophiolite complex which provides access to rocks which once made up the Oceanic crust and upper mantle. He has published in journals including Nature, Tectonics, Terra Nova, and Earth and Planetary Science Letters and has received funding from the National Science Foundation for his research. His work in western Canada has been influential in both understanding magmatic arcs and the paleogeography of North America.
