Dr. Guirgis, University Professor of Sciences and Mathematics at the College of Charleston, has had a long and distinguished career in both industry and academia. He received in 1962 his B.Sc. Chemistry from Cairo University, Cairo, Egypt, and in 1969 his M.Sc. Organic Chemistry from Ain-Shames University, Egypt. He emigrated to the United States that same year and began work with Bayer Corporation, first in New Jersey, and since 1970 at its Bushy Park Facility near Charleston, rising through the ranks to become a Senior Research Fellow. During this time he completed his Ph.D in 1979 in Physical/Analytical Chemistry from the University of South Carolina, Columbia, SC. He became a long time collaborator with his Ph.D. mentor, Dr. James R. Durig. In 1992 he was named a Research Professor in the College of Science and Mathematics at the University of South Carolina. In 1994 he was appointed to the same position at the University of Missouri- Kansas City. Since retirement in 2001 he has been an adjunct professor at the College of Charleston and was recently named a University Professor in recognition of his work with undergraduate research students. Dr. Guirgis is the author of over 240 referred publications and has world-wide scientific connections and collaborations and is a Fellow of the Royal Society of Chemistry
