  • Dr. Beitle joined the Department of Chemical Engineering at the UA in August 1993. In 1998 he was awarded tenure and promoted to Associate Professor, and in 2006 he achieved the rank of Full Professor. His primary research interests are in the field of biochemical engineering, with an emphasis on bioseparation and fermentation, and adaptive technology for the disabled. 

Dr. Beitle teaches upper level and graduate level courses in chemical engineering, and enjoys challenging students to apply their fundamental learning in a variety of settings. He has received teaching awards both as a graduate student (1988) and as a faculty member (1998, 2003, and 2007), and has been recognized as an outstanding mentor at the University of Arkansas three times. He is a member of the American Institute of Chemical Engineers, the American Chemical Society, and various other technical and honorary societies. He has served on the Executive Committee for the Biochemical Technology Division within ACS, and is a longstanding member of the Cell and Molecular Biology Program Advisory Committee at the University of Arkansas.
