Biography
Dr. Frank Giblin received his Ph.D. in biochemistry from the State University of New York at Buffalo in 1974. He has conducted NIH-funded metabolic and biochemical studies on the lens and cataract for over 35 years. He is particularly interested in the possible role of oxidative and free radical processes in the formation of nuclear cataract, a common type of maturity-onset human cataract that affects the center of the lens, resulting in blindness. He also investigates unusually active antioxidant mechanisms present in the epithelium of the lens that help to keep the tissue transparent.
Assisting Giblin in his studies is Research Technician Victor Leverenz. A number of students have also helped Giblin including, most recently, Dan Feldmann. Experimental animal models used by the group to study mechanisms of cataract include hyperbaric oxygen, UVA light), X-irradiation and the thioredoxin reductase-1 heterozygous knockout mouse. He also studies retinal photoreceptor damage in O2-treated mice and collaborates with retinal surgeons (William Beaumont Hospital) on an enzymatic replacement for vitrectomy surgery. Techniques that are employed include gel electrophoresis, immunoblotting, autoradiography, tissue culture, HPLC, enzyme analysis, microarray analysis, RT-PCR, Real-Time PCR and Northern Blotting.
In addition to his research activities, Giblin serves as a Lens Section Editor for Experimental Eye Research and was a member of the NIH VIS-A Study section from 1995-99. He co-organized a session for the 2010 ICER meeting in Montreal. Here at Oakland University he is a former chair of the Institutional Animal Care and Use Committee. In 2007, Giblin received the Kinoshita Lectureshhip Award for his studies on cataract. In 2011, he presented the keynote lecture at the 50th annual meeting of the Japanese Cataract Research Society in Fukuoka, Japan.
