Dr. Crosson is a physical chemist interested in environmental problems. Previously, he spent two years as a post-doctoral researcher at Brookhaven National Lab and focused on projects related to nanoparticle/soil/microbial interactions and on bioremediation of uranium impacted soils. He came to the University of Dayton in 2007.

Dr. Crosson completed his doctoral studies at Penn State in Solid-State Nuclear Magnetic Resonance Spectroscopy with Professor Karl T. Mueller. Using NMR, and other analytical methods, alkaline dissolution of clay minerals was studied to better understand the impact of dissolution on (1) the formation of porous aluminosilicate minerals in environmental systems and (2) the environmental fate of cesium under extremely alkaline conditions.

At University of Dayton, Dr. Crosson's group focuses on developing spectroscopic and other molecular methods to interrogate environmentally complex contaminated soil systems. Students will gain experience in NMR, Fluorescence and macroscopic methods of analyzing soils (and components) and will learn about contaminant transport processes. Dr. Crosson is a member of the National Organization of Black Chemists and Chemical Engineers and the American Chemical Society (Environmental Chemistry Division).

Faculty Perspective

I believe students should be well trained in current procedures and properly educated in the theory and processes involved in order to attain future intellectual growth and professional progress. I tune in to the diverse learning methods of my students and tailor lectures and assignments to make the best connection with my students. I use real-world examples to familiarize students with issues chemists consider when faced with certain situations. I also recognize that not all students taking chemistry are interested in becoming chemists. However, I strive to give students a well-rounded experience, which will allow them to transfer skills and knowledge to a variety of job opportunities.

Research Interests

  • Environmental and Physical Chemistry
  • Spectroscopy (Solid-State NMR and Fluorescence)
  • Currently interested in molecular level environmental studies of the fate and transport of industrial chemicals, emerging contaminants, and novel materials (e.g. nanomaterials) proposed for widespread industrial or personal uses.
