Dr. Morris studies air quality using weather balloons. His Houston project includes more than 500 flights since 2004 involving over 40 students, mostly undergraduates. His air quality work has taken him to Panama, Costa Rica, and Japan. Dr. Morris arrived at St. Ed's in July 2014 as Dean of NSCI.

Dr. Morris teaches physics, astronomy, meteorology & earth science. He held a Dept. of Energy Global Change Graduate Fellowship and a National Research Council Post-Doctoral Fellowship at NASA studying the ozone layer before becoming a research faculty member at UMBC. He began studying ozone pollution while a Weiss Instructor of Physics at Rice (2000 - 2004), where he started his weather balloon project, then taught at Valparaiso U. from 2004 - 2010 before becoming Associate Dean there. During 2008 and 2009 he was a Fulbright Scholar in Japan studying the influence of Chinese pollution before, during, and after the Olympics. Dr. Morris served two terms as Dean of Natural Sciences at SEU from 2014 - 2020 before returning to the faculty in Fall 2020.

Research

Research

My research focuses on measurements and modeling of air quality (particularly ozone) and physics education research.  My air quality research has centered on Houston, Texas since 2004, resulting in the largest megacity ozonesonde profile dataset in the world (>500 profiles).  My air quality project website can be found at http://physics.valpo.edu/ozone.  I also had the chance to pursue a Fulbright Scholar research project in Japan (2008 - 2009, blog at http://polympics.wordpress.com.)
