Lawrence Margerum

Professor

Dr. Margerum graduated from Dartmouth in 1980 with a BA in chemistry and a senior thesis for Dr. Russ Hughes in organometallic chemistry. He was also a quarterback on the Dartmouth Football team, earning All-Ivy honors as a senior punter. During the next 5 years, he was a graduate student under Dr. Tom Meyer and Dr. Royce Murray at the University of North Carolina. He completed the PhD in inorganic photochemistry and electrochemistry in 1985 and moved to UCLA for post-doctoral work under Dr. Joan Valentine (bio-inorganic chemistry).

Dr. Margerum started his professional career in 1987 at the Clorox Technical Center investigating such areas as bleach stable metal chelates. In 1991, he moved to Nycomed Salutar Imaging in Sunnyvale, CA, leading a team of scientists developing a Gd(III) contrast agent for blood imaging. In 1995, he joined USF as assistant professor of analytical and inorganic chemistry. He currently has undergraduate and masters students exploring the following research areas:
- The Effect of Dendrimer Size and pH on the Binding of Metal Complexes using electrochemistry.
- Immobilized Dendrimers as Platforms for Multivalent Binding of Metal Ions using spectroscopy techniques and solid-phase synthesis.
- Implementing technology-based learning tools for chemical education (OWL, CPR, clickers in the classroom, POGIL).

He teaches courses in general, analytical and inorganic chemistry.
