D. Larry Eng-Wilmot , Ph.D. Professor of Chemistry |
I received my B.S. degree in Chemistry from Eckerd College in 1969, and earned a Ph.D. in Inorganic Chemistry from the University of South Florida in 1978, working with the Distinguished Professor of Chemistry, Dean F. Martin. I was awarded a postdoctoral research fellowship in the laboratory of George Lynn Cross Professor of Chemistry, Dr. Dick van der Helm at the University of Oklahoma from 1978 to 1980. In 1980, I joined the faculty at Rollins College, and in 1986 was awarded an Arthur Vining Davis Fellowship. In 1990, I was named Archibald Granville Bush Professor of Natural Science, holding this chair until 1997. I have been awarded grants from NSF, FIPSE, Research Corporation, and have authored or coauthored 22 research publications. I am an Eagle Scout and a veteran, serving in the U.S. Navy from 1971 to 1975, with two personal commendations.
Teaching Interests:
My teaching interests are in physical inorganic chemistry and the coordination chemistry of transition metals, solution equilibria, and analytical chemistry. The courses I have taught include:
Chemistry I and II (CHM 120 / CHM 121)
Analytical Chemistry (CHM 320)
Inorganic Chemistry (CHM 401)
Advanced Analytical Chemistry (CHM 400)
Chemical Investigations I, II, and IV (CHM 388 / 389 / 489)
August 12, 2005 and Society (CHM 105)
Chemistry and Environment (CHM 110)
Chemical Synthesis and Analysis (CHM 219)
Chemistry in the Marketplace (CHM 108)
Research Interests:My research are in the areas of natural products and molecular structure determination by spectroscopic methods and single crystal X-ray diffraction, coordination chemistry, bioinorganic chemistry, and microbial iron transport. Current research with my students focuses on the role of molecular structure and stereochemistry in the biological activities of iron (III) selective membrane transport compounds, or siderophores, and their involvement in organism-organism interactions. I have recently been involved in the studies of these compounds and their effect on fungi producing edible mushrooms, analysis of aluminum ion in the Winter Park Chain of Lakes, and the isolation and purification of light tracking compounds in higher plants, in collaboration with Dr. Judy Schmalstig in the Department of Biology at Rollins.
I am also interested in research relating to chemical education, curriculum development, problem-based learning, and the factors involved in how students develop conceptual understanding of chemical principles and the role of molecular visualization in this process.
