Kevin A. Schug is a Full Professor and Shimadzu Distinguished Professor of Analytical Chemistry in the Department of Chemistry & Biochemistry at The University of Texas (UT) at Arlington. He joined the faculty at UT Arlington in 2005 after completing a Ph.D. in Chemistry at Virginia Tech under the direction of Prof. Harold M. McNair and a post-doctoral fellowship at the University of Vienna under Prof. Wolfgang Lindner. Research in the Schug group spans fundamental and applied areas of separation science and mass spectrometry. Schug was named the LCGC Emerging Leader in Chromatography in 2009, and the American Chemical Society Division of Analytical Chemistry Young Investigator in Separation Science awardee in 2012. More recently, he has been honored with the Silver Jubilee Medal from The Chromatographic Society (UK) in 2024.

I have had enough conversations with experts in the field of high performance liquid chromatography (HPLC) stationary-phase supports to know that there is more to the increased efficiency provided by the use of superficially porous particles (SPP) compared to fully porous particles (FPP) than simply mass transfer effects. Yet, I would argue that this is still one of the biggest misconceptions propagated by some members of the chromatography community.
