Arnold Appointed To Green Chair In Laser-Chemistry
Mark A. Arnold, professor of chemistry in the University of Iowa College of Liberal Arts and Sciences (CLAS) and director of the UI Optical Science and Technology Center (OSTC), has been appointed to the Edwin B. Green Chair in Laser-Chemistry through June 2010.
In making the announcement, Linda Maxson, CLAS dean said: "Through this appointment we demonstrate our pride in Professor Arnold's scholarly work and professional contributions and the distinction he brings to the Department of Chemistry, the college, and the university."
Arnold started at the UI in 1982 as an assistant professor in the Department of Chemistry. He has more than 150 publications in peer-reviewed journals, more than 300 scientific presentations and seven issued U.S. patents. His research interests center on the development, characterization and implementation of chemical sensing technology. His career at Iowa includes pioneering developments in the fields of fiber-optic chemical sensors, biosensors for monitoring the release and uptake of amino acid neurotransmitters, and unique sensors designed for the selective measurement of gaseous species dissolved in aqueous media. His contributions are notable in an array of areas, including analytical sciences, neurochemistry, bioreactor monitoring and clinical chemistry.
In recent years, Arnold's research efforts have focused on the development of near infrared spectroscopy for noninvasive chemical analysis, with a particular emphasis on the noninvasive measurement of blood glucose in people with diabetes. Arnold is recognized internationally for his contributions and leadership role in the development of noninvasive blood glucose sensing technology. Other applications of near infrared spectroscopy under development in the Arnold Research Group include noninvasive measurements of glucose and other metabolites in bioreactor growth media, blood and tissue lactate levels for critically ill patients, as well as systemic urea concentrations to optimize hemodialysis treatments and to monitor the success of kidney transplants.
Arnold currently is the principle investigator on four separate multi-year grants from the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) and the National Aeronautics and Space Administration (NASA). The objective of these grants is to develop novel noninvasive sensing technology for glucose and other targeted biomolecules. One grant is a $2.5 million multi-investigator effort to develop a novel blood glucose sensor for the management of diabetes. The goal is to develop a glucose monitor that examines a small volume of interstitial fluid continuously extracted from under the skin. The glucose concentration of the fluid is measured noninvasively with a chip-based, near-infrared spectrometer.
The Green Chair is named for Edwin B. Green, former Iowa City Press-Citizen editor. "I am proud and honored to be selected to hold this prestigious chair, and I'm very grateful to the Green family for their support of optical sciences at the University of Iowa," Arnold said.
The Green Chair is a five-year, renewable appointment that includes a salary supplement and an annual discretionary fund for enhancing scholarly work. Arnold plans to use these funds to explore exciting new research ideas, such as the use of laser traps to characterize interactions and communication mechanisms between living cells.`
