Wayne Hubbell, Ph.D.

Biography

During his graduate and postdoctoral work with Harden McConnell at Stanford University, Wayne Hubbell used spin label technology to first describe the fluidity and fluidity gradient in biological membranes, landmark discoveries of broad impact in cell and membrane biology.

In 1970, he joined the faculty of the Department of Chemistry at UC Berkeley where his laboratory designed new surfactants, pioneered the molecular characterization of reconstituted membrane proteins, and developed a series of unique spin label probes to study membrane electrostatics.

In 1983, Prof. Hubbell moved his laboratory to UCLA where he became the first Jules Stein Professor of Ophthalmology and Professor of Chemistry and Biochemistry. Soon after arriving, he combined unrelated technical advancements in molecular biology and EPR spectroscopy and pioneered the powerful new technology of site-directed spin labeling (SDSL) for the determination of structure and conformational dynamics in both soluble and membrane proteins.

For his development and application of SDSL, Prof. Hubbell has received numerous honors and awards including the Gold Medal of the International EPR/ESR Society, the International Zavoisky Award from the Physical Technical Institute of the Russian Academy of Sciences, the Bruker Prize from the Royal Society of Chemistry-ESR Group, and the Elisabeth Roberts Cole from the Biophysical Society (US). He is a member of the National Academy of Sciences, American Academy of Arts and Sciences, elected to the first class of fellows of the Biophysical Society and recipient of an honorary doctorate from the University of Pécs, Hungary.

Research Interests

Dr. Piri’s research is aimed toward understanding the molecular mechanisms leading to retinal ganglion cells (RGC) death in glaucoma. It has been established that RGCs die by apoptosis in glaucoma, but the exact pathway from death stimulus to cell death is not understood. As an initial step in identifying potential factors responsible for RGC apoptosis, Dr. Piri’s laboratory is analyzing gene expression patterns that are altered in glaucomatous retinas using DNA microarrays and proteomic technologies, as well as conventional molecular biology, biochemistry and genetic methods. Another area of interest is the identification of new genes that are expressed exclusively or preferentially in RGCs. Currently, Dr. Piri is investigating the roles of several RGC-expressed novel genes in RGC differentiation and metabolism, and their possible involvement in glaucomatous or other optic neuropathies. Gene and protein expression studies may lead to a better understanding of the regulatory events involved in RGC apoptosis, and provide molecular targets for the development of new therapeutic agents with neuroprotective effects in order to prevent or delay the loss of ganglion cells in glaucoma.
