Richard Schatz is research director of cardiovascular interventions at the Scripps Heart, Lung, and Vascular Center and director of gene and stem cell therapy. He is a recognized international expert in interventional cardiology and has published and lectured extensively. His seminal work in coronary stents spurred a revolution in the treatment of coronary artery disease—over 2 million of them are placed annually worldwide, with an immeasurable impact on relieving mortality and morbidity, improving patients’ lives, and reducing healthcare costs.  

Dr. Schatz served his internship and residency at Letterman Army Medical Center in San Francisco, forward by a fellowship at Brooke Army Medical Center at Fort Sam Houston, where he was, successively, director of the Cardiovascular Technologist School, Cardiology Clinic, Coronary Angioplasty, and Cardiac Catheterization Labs, before becoming assistant chief and then acting chief of cardiology.

He was also a clinical associate professor of medicine at the University of Texas Health Sciences Center in San Antonio, where he collaborated with Dr. Julio Palmaz to develop a novel approach to angioplasty, pioneering the field of vascular stents. In 1988 they received FDA approval to proceed with the first US protocol to study stents in the coronary circulation and in 1994 the FDA approved the Palmaz-Schatz stent, the first stent to reduce restenosis, heralding a new era in the treatment of coronary disease. With nearly 100 million patients treated worldwide the Palmaz-Schatz Stent is one of the top 10 medical device patents of the last 50 years.

His collaboration with the late Jeffrey Isner in angiogenesis, gene transfer, and stem cell therapy launched a new approach to relieving angina in patients with atherosclerosis and improving heart function after heart attacks.

Dr. Schatz has been honored with both the distinguished alumnus award and the Lifetime Scholar Award by Duke University Medical Center, and he is a distinguished fellow of the Hong Kong Cardiology Society as well as an elected fellow of the American College of Cardiology.

Adolf Fercher chaired the Institute of Medical Physics at the Medical University of Vienna (1986–2008) and is now professor emeritus.

He pioneered ophthalmic interferometry, demonstrating the first measurement of the axial length of a human eye using low-coherence interferometry (LCI; 1986) and one of the first retinal OCT images of the living human eye (1993), and he is the intellectual father of the first commercial LCI ocular biometry system. In 1995 Dr. Fercher demonstrated, together with Christoph K. Hitzenberger, the first application of spectral domain (SD) LCI to intraocular ranging, enabling rapid 3D OCT imaging and modern OCT technology.

Dr. Fercher is the author or coauthor of some 125 scientific publications in peer-reviewed journals. He studied physics at Vienna University of Technology and received his PhD in 1972. In 1968–1975 he was junior scientist at Carl Zeiss AG, where he worked on optical testing with computer holograms and in holographic interferometry. In 1975–1986 he was professor at the University of Essen, where he conducted research on laser speckle and biomedical applications of interferometry.

James Fujimoto is Elihu Thomson Professor of Electrical Engineering and Computer Science at the Massachusetts Institute of Technology, a visiting professor of ophthalmology at Tufts University School of Medicine, and an adjunct professor at the Medical University of Vienna. His group and collaborators were responsible for the invention and development of optical coherence tomography (OCT). Their paper, “Optical Coherence Tomography,” published in Science in 1991, remains one of the most cited papers in the biophotonics field. Working with Carmen Puliafito and Eric Swanson, he was a cofounder of the startup company Advanced Ophthalmic Devices, which developed OCT for ophthalmic imaging and was acquired by Carl Zeiss. He also cofounded, with Eric Swanson and Mark Brezinski, LightLab Imaging, which developed cardiovascular OCT and was acquired by Goodman, Ltd. and St. Jude Medical.

In addition to publishing over 450 peer-reviewed journal articles and coediting 13 books, Dr. Fujimoto is an influential educator—numerous researchers who trained in his group are now leaders in photonics and biophotonics. He is also active in scientific service. He is a director of the International Society for Optics and Photonics (SPIE), has been general cochair of the SPIE BIOS symposium since 2003, and was program and general cochair for the 2002 and 2004 Conferences on Lasers and Electro Optics (CLEO), cochair of the 2005 European Conferences on Biomedical Optics, and director of the Optical Society of America from 2000 to 2003.

Christoph Hitzenberger is vice chair of the Center for Medical Physics and Biomedical Engineering at the Medical University of Vienna. He joined the Institute of Medical Physics at the University of Vienna in 1987 as an assistant professor and, with the new head of the department, Adolf F. Fercher, founded the biomedical optics research group. During their pioneering work on low-coherence intraocular ranging, Dr. Hitzenberger developed the first heterodyne low-coherence interferometry (LCI) system for measuring intraocular distances (axial eye length, retinal thickness), presented in 1990. This work led to the development of the first commercial LCI ocular biometry system that is now standard technology in eye clinics worldwide and has been successfully used for intraocular lens adaptation in millions of cataract patients. The technology was expanded to record optical coherence tomography (OCT) images, yielding one of the first in vivo retinal OCT images of the human eye.

In 1995 Dr. Hitzenberger demonstrated, in cooperation with Dr. Fercher, the first application of spectral domain (SD) LCI to intraocular ranging. The huge sensitivity advantage of SD LCI/OCT over the earlier time domain technology led to a paradigm shift in OCT technology and enabled rapid 3D imaging. SD OCT has revolutionized retinal diagnostics and is now the industry standard for retinal OCT, with tens of thousands of SD OCT retinal scanners in use worldwide.

Dr. Hitzenberger received the award of the Hoechst Foundation for Advancement of Medical Research in Austria and is a fellow of the International Society for Optics and Photonics (SPIE) and the Optical Society (OSA). In addition to serving as editor in chief of the OSA journal Biomedical Optics Express, he is the author or coauthor of some 150 scientific publications in peer-reviewed journals, with a total of nearly 20,000 citations (Google Scholar).

He studied physics and mathematics at the University of Vienna and received his PhD in 1983. He earned his habilitation in medical physics 1993.

David Huang is the Peterson Professor of Ophthalmology, professor of biomedical engineering, and director of the Center for Ophthalmic Optics and Lasers in the Casey Eye Institute at the Oregon Health and Science University in Portland.

He co-invented optical coherence tomography (OCT) in 1991 when he was an MD/PhD student at Harvard Medical School and the Massachusetts Institute of Technology. This novel imaging technology has micron-level resolution in all 3 dimensions and is able to resolve cell-sized microstructures in the retina and other fine layered structures of the eye. It is indispensable in the diagnosis and management of many eye diseases and has become the most commonly used imaging modality in ophthalmology, with an estimated 30 million people scanned every year worldwide. He has made further contributions to various aspects of OCT technology, including polarization-sensitive OCT, swept-source OCT, anterior eye OCT, OCT angiography, and spectroscopic OCT of nanoparticle-labeled cells.

Dr. Huang leads the Center for Ophthalmic Optic and Lasers (), which conducts NIH-supported basic, translational, and clinical research on OCT and OCT angiography in retinal diseases, anterior eye disease, glaucoma, and other optic nerve diseases. He is also an inventor of laser therapeutic devices and mobile diagnostic technology, and a founder of Gobiquity Mobile Health (), a maker of mobile diagnostic apps for both professional and home use.

For his research and teaching on OCT, Dr. Huang shared the 2012 António Champalimaud Vision Award and received the Association for Research in Vision and Ophthalmology’s Jonas Friedenwald Award (2013) and the American Academy of Ophthalmology’s Senior Achievement Award (2011). He is a fellow of the National Academy of Inventors.

Michael M. Merzenich is the Francis Sooy Professor (emeritus) at the University of California, San Francisco, and a founding scientist at Scientific Learning, Posit Science, and the Brain Plasticity Institute.

Merzenich led a research team that conducted extensive, original research important for the development and application of multiple-channel cochlear implants, which ultimately provided the bases for a commercial cochlear implant (Advanced Bionics’ Symbion). In 1996 he cofounded Scientific Learning, a company dedicated to delivering remedial therapies to address language, reading, attention, and cognitive impairments in school-age children. Its programs have been applied to help more than 5 million children. In 2002 he cofounded Posit Science, which produces and delivers computer-based programs to help aging, psychiatrically impaired, and brain-injured populations.

In 2009 Merzenich and his colleagues founded the Brain Plasticity Institute, a research company (later integrated back into Posit Science) that has focused on developing new treatment strategies for children and adults with severe neurological impairments. Current targets are schizophrenia prevention/treatment; major depressive and bipolar disorders; resilience training to delay the onset of schizophrenia, Alzheimer’s, Huntington’s, and Parkinson’s; “chemobrain”; brain infections; autistic spectrum disorders; ADHD and conduct disorders; childhood abuse syndromes; substance abuse disorders; hemispatial neglect syndrome; aphasias; and acquired movement disorders.

His research interests have included the functional organization of the somatosensory and auditory nervous systems; the neurological bases of—and rules governing—learning-induced cortical plasticity; and the neurological origins of and remediation of developmental and acquired impairments in language, reading, memory, attention, cognitive control, and movement. His research teams have extensively modeled changes induced in the brain (a) following brain injury and stroke; (b) resulting from distorted experiential history leading to acquired impairments, psychotic illness, and addiction; and (c) contributing to pathological neurological regression in aging. All have been studied as platforms for developing brain plasticity–based medical therapeutics to treat those conditions in human populations.

Merzenich earned his bachelor’s degree at the University of Portland and his PhD at Johns Hopkins. He was elected to the National Academy of Sciences in 1999 and the Institute of Medicine in 2010.

R. Srinivasan came to the United States from India in 1953 for his graduate work in Chemistry. He got his Ph. D. under Sidney Benson, the well-known chemical kineticist. His thesis was on protein chemistry which served him well thirty years later in the work that has resulted in the Russ prize.

After several years of post-doctoral work at Caltech and at the University of Rochester, Srinivasan joined the IBM Watson Research Center in Yorktown Heights, NY in 1961. For the next thirty years he investigated the action of ultraviolet photons on organic molecules. His research extended from the photochemistry of small organic molecules such as 1,3 –butadiene to synthetic organic polymers which were used as photoresists in the manufacture of computer chips. In 1980, when pulsed, ultraviolet(UV) lasers became commercially available, he switched his studies to the action of nanosecond UV pulses on organic solids. He discovered the phenomenon of â€śAblative Photodecomposition (APD)” in synthetic organic polymers in 1979 and extended it to biological tissue in 1981. APD is currently used in the packaging of electronic chips and in the manufacture of ink-jet printers.

Srinivasan and his co-worker, James Wynne, collaborated extensively with surgeons from 1983 to 1991 to find potential applications of APD in surgery. The one field where the invention has succeeded impressively is in the re-shaping of the human cornea in the eye to correct for problems in vision such as myopia (short-sight), hyperopia (long-sight) and astigmatism. This discovery has led to the award of the Russ Prize for 2013 to Srinivasan, Wynne and Samuel Blum.

Srinivasan retired from IBM in 1990. He is currently the President of UVTech Associates, a consulting company.

Leroy E. Hood received an M.D. from Johns Hopkins University and a Ph.D. from California Institute of Technology, where he was a faculty member for 22 years. Dr. Hood’s research initially focused on fundamental biology (immunity, evolution, genomics, and neurobiology) and on bringing engineering and biology together through the development of five instruments—a DNA sequencer, a DNA synthesizer, a protein sequencer, a peptide synthesizer, and an ink jet printer for DNA arrays—all of which have since been commercialized (Applied Biosystems and Agilent).
