                Interview with Prof. Kevin A. Schug




            We interviewed with Dr. Kevin A. Schug, Associate Professor and Shimadzu Distinguished Professor of Analytical
            Chemistry in the Department of Chemistry and Biochemistry at the University of Texas at Arlington (UT Arlington). His
            research is mainly on the separation of bioactive chemical compounds with mass spectrometry techniques. Also, he is
            currently undertaking one of the most extensive investigations of the potential impact of industrial processes, such as
            unconventional drilling and hydraulic fracturing, on our environment. He and Shimadzu started collaborative work in
            2012 when the Shimadzu Center for Advanced Analytical Chemistry was established.
