F. Peter Guengerich Award for Mentoring Postdoctoral Fellows or Residents in the Research Setting — Christopher V.E. Wright, D.Phil., Louise B. McGavock Professor, Department of Cell and Developmental Biology
Wright received his Bachelor of Science degree at the University of Warwick, and his doctorate in Biochemistry at the University of Oxford. From 1985 to 1990, he did postdoctoral work, first at the Medical Research Council in Cambridge, and then at UCLA. In 1990, Wright joined the faculty at Vanderbilt as an assistant professor of Cell Biology. Within seven years, he was a full professor in the renamed Department of Cell and Developmental Biology.
Wright is a member of a premier group of researchers working on pancreas organogenesis, differentiation of the insulin-producing beta cell and the potential for stem cell therapy to address pancreatic dysfunction. He published the first description of the gene pdx1, which – it has since been learned — is essential for development of the pancreas and for maintenance of the adult beta cell. In humans, certain mutations in this gene are associated with increased risk for developing a form of type 2 diabetes. Wright also discovered that pdx1 and another regulatory gene, Ptf1a, signal progenitor cells to become pancreas. Wright is an investigator in the Beta Cell Biology Consortium, an international effort to develop cell-based therapies for diabetes funded by the National Institutes of Health (NIH). He has contributed to nearly 150 scientific publications.
In 1999, Wright was appointed director of the Program in Developmental Biology, a cross-campus, multi-disciplinary group of 285 researchers that fosters innovative and interspecies approaches to studying fundamental questions in embryonic development. He is the principal investigator of a longstanding NIH training grant that is a cornerstone of the Program in Developmental Biology, and served for several years as his department’s representative to Vanderbilt’s Interdisciplinary Graduate Program. Since 1990, he has mentored 15 graduate and M.D./Ph.D. students and 12 postdoctoral fellows, and has encouraged them to gain teaching experience as course directors.
John S. Sergent Award for Teaching Medical or Graduate Students in the Small Group Setting — Amy Fleming, M.D., associate professor of Pediatrics
Fleming earned her Bachelor of Arts degree in Biology from the University of Virginia, and in 1993 enrolled in both the University of Virginia School of Medicine and the United States Air Force Reserves Health Professional Scholarship Program.

She has received several awards for her contributions to medical education at Vanderbilt, including the Shovel Award, the medical school’s highest teaching award. She is a fellow of the American Academy of Pediatrics, and plays leadership roles in the national organizations involved in medical education.
OUTSTANDING CONTRIBUTIONS TO RESEARCH
William J. Darby Award for Translational Research that has Changed the Practice of Medicine Worldwide — Jeffrey A. Sosman, M.D., Ingram Professor of Cancer Research and professor of Medicine
Sosman earned his Bachelor of Arts degree from Brandeis University. After receiving his medical degree from Albert Einstein College of Medicine, he completed a medical residency and medical oncology fellowship at the University of Wisconsin. He had faculty appointments at Loyola University and the University of Illinois before coming to Vanderbilt in 2001 as professor of Medicine in the Division of Hematology/Oncology and director of the Melanoma Program at the Vanderbilt-Ingram Cancer Center (VICC). He also is co-leader, with Albert Reynolds, Ph.D., of the Signal Transduction and Cell Proliferation Program.
Sosman is committed to developing and testing new drugs and targets for the treatment of malignant melanoma, the most deadly form of skin cancer, while working closely with basic researchers to understand the underlying mechanisms of this disease. He has contributed to more than 150 peer-reviewed scientific publications, and has participated in clinical trials that have advanced the treatment of melanoma. Many of these recent advances have been made possible by the ability to screen patients for mutations in genes such as BRAF that increase their risk of developing melanoma or which affect their tumor’s response to treatment.
Sosman participates in VICC’s Personalized Cancer Therapy initiative, which offers cancer patients routine “genotyping” of their tumors to determine which treatment will be most effective. During the past three years, he has contributed to clinical trials of new “personalized medicines” that have caused significant tumor shrinkage, nearly doubled overall survival rates, and which appear to delay the development of resistance to treatment.
In 2009, he received the first American Cancer Society Mary Hendrickson-Johnson Melanoma Professorship, a five-year, $400,000 award for “landmark” contributions to melanoma research. He also is part of multi-center teams that have received major support from the Melanoma Research Alliance and the Stand Up To Cancer Initiative.
Sidney P. Colowick Award for Research that Serves as a Platform for Discovery in Diverse Areas — Craig W. Lindsley, Ph.D., William K. Warren, Jr., Professor of Medicine and professor of Pharmacology
Lindsley earned his Bachelor of Science degree from California State University, Chico, and his Ph.D. in Chemistry from the University of California, Santa Barbara, and pursued postdoctoral studies at Harvard University. In 2001, after brief stints at Parke-Davis and Eli Lilly, he joined the Medicinal Chemistry Department at Merck & Co. in West Point, Pa., where as senior research fellow/group leader of the Technology Enabled Synthesis group, he developed a streamlined approach for lead optimization, resulting in the accelerated delivery of six preclinical candidates.
A pioneer in the development of selective allosteric modulators, Lindsley came to Vanderbilt in late 2006. He is director of Medicinal Chemistry in the Vanderbilt Center for Neuroscience Drug Discovery, which is focused on development of allosteric modulators of G protein-coupled receptors for the treatment of schizophrenia, Parkinson’s disease, Alzheimer’s disease, Fragile X syndrome and depression. Lindsley also directs the Vanderbilt Specialized Chemistry Center for Accelerated Probe Development, part of the NIH-supported Molecular Libraries Probe Production Centers Network, and he has contributed to the development of the first selective inhibitors of the enzyme phospholipase D, and which could represent a new class of drugs for treating cancer.
In introducing his award, Heidi Hamm, Ph.D., chair of Pharmacology on scholarly leave of absence this year, said, “Craig’s role here at Vanderbilt has been nothing short of transformative … He led the chemistry effort in the neuroscience drug discovery program that allowed four novel programs to advance to the clinical candidate stage in 2011, and three of which will be in Phase I clinical trials this year.”
Lindsley has published more than 225 scientific papers, holds 28 issued U.S. patents, and has filed more than 238 patent applications since arriving at Vanderbilt. He has been honored nationally for his “major impact” on medicinal chemistry research.
Ernest W. Goodpasture Award for Groundbreaking Research that Addresses the Pathogenesis of Infectious Disease or Important Biological Problems in Immunity — Christopher R. Aiken, Ph.D., professor of Pathology, Microbiology and Immunology
Aiken received his Bachelor of Science degree in Chemistry from the University of California, Santa Barbara, and his Ph.D. in Biochemistry from the University of Illinois at Urbana-Champaign. After completing a postdoctoral fellowship in Molecular Virology at the Salk Institute for Biological Studies in 1995, he joined the Vanderbilt faculty as an assistant professor. In 2005, he was appointed full professor in what is now known as the Department of Pathology, Microbiology and Immunology. Since 2006, he has served as director of Graduate Studies for the department’s Graduate Program in Microbiology and Immunology.
Since the early 1990s, Aiken has studied the biological processes that control replication of HIV-1. He and his colleagues made the original discoveries that the Env glycoproteins that form the viral envelope are tightly associated with the immature HIV-1 core, and that immature HIV-1 particles are repressed for fusion to their target T lymphocytes by an activity of the gp41 cytoplasmic tail. These discoveries have implications for efforts to produce an effective HIV-1 vaccine.
Recently Aiken’s group, led by postdoctoral fellow Amanda Joyner, Ph.D., reported that immature viral particles exhibited markedly enhanced binding of several gp41-specific antibodies, including two that recognize the membrane proximal external region (MPER) epitopes and which neutralize diverse HIV-1 strains. These results suggest that masking of neutralization-sensitive epitopes during particle maturation may contribute to the ability of HIV-1 to evade the immune system.
Aiken’s group also has made significant contributions to understanding viral capsid disassembly, another key step in HIV replication. They pioneered approaches for studying capsid disassembly in vitro and, in collaboration with researchers at the University of Pittsburgh, performed detailed structural studies of the capsid program. His team is actively studying the antiviral mechanism of inhibitors targeting the HIV-1 capsid, representing a new frontier in antiretroviral therapy.
Leadership of a Multi-investigator Team Award for Two or More Faculty Working Collaboratively or in a Multidisciplinary Manner to Address Important Biological Processes and/or Diseases — Alan D. Cherrington, Ph.D., Jacquelyn A. Turner and Dr. Dorothy J. Turner Professor of Diabetes Research, and professor of Molecular Physiology & Biophysics and of Medicine; Owen P. McGuinness, Ph.D., professor of Molecular Physiology & Biophysics; Masakazu Shiota, DVM, Ph.D., associate professor of Molecular Physiology & Biophysics; David H. Wasserman, Ph.D., Annie Mary Lyle Professor, Department of Molecular Physiology & Biophysics; and Phillip E. Williams, B.S., research associate professor of Surgery
These researchers are being honored for their elegant work on the development of experimental glucose clamp techniques in dogs, rats and mice. These innovations have helped transform diabetes research around the world, not only in the field of metabolism, but in studies of genetics and drug discovery as well.
The glucose clamp technique, developed in the mid-1970s, is a method of quantifying insulin secretion and sensitivity. By measuring how much glucose must be infused into the bloodstream to maintain a constant concentration of glucose, researchers can determine how well beta cells in the pancreas are responding by secreting insulin. Another clamp technique measures how much glucose must be infused to maintain a constant glucose concentration when insulin also is infused. In this way, researchers can determine how well the muscle tissues of the body are taking up glucose. Insulin “resistance” occurs when tissues do not respond normally to the hormone.
During the past 40 years, members of this talented team helped define the interplay of glucagon and insulin in controlling levels of blood glucose. In addition to moving glucose from the bloodstream into muscle, where it can be burned for fuel, it was shown in an animal model that insulin could also slow glucose production by the liver. Glucagon, another pancreatic hormone, opposes the action of insulin on the liver. It can speed up glucose production in situations where the body’s demand for glucose has outstripped its supply.
These discoveries were facilitated by a clamp technique in which a variable insulin infusion was titrated against a fixed glucagon infusion until glucose was stable. Williams, who developed the surgical and experimental procedures, has a remarkable ability to implant catheters in small deep vessels. This allowed the creation of unique models of hormone deficiency and other experimental designs that are now known worldwide.
Wasserman extended these experiments, defining the endocrine regulation of the exercise and post-exercise state. In the early 1990s, he applied glucose clamp techniques to a rat model to define the regulation of muscle glucose uptake and insulin resistance using a novel triple isotope technique. McGuinness combined clamp and isotopic techniques with models of infection and nutrient delivery to study conditions present in patients under intensive care conditions.
As director of the Small Animal Core of the NIH-funded Vanderbilt Diabetes Research and Training Center(DRTC) in the mid-1990s, Shiota developed catheterization and clamp techniques for application to the conscious, unstressed mouse. This achievement coincided with the development of transgenic mouse models, which made it possible to study how specific genes regulate fundamental metabolic processes. During the past nine years, Wasserman, McGuinness and Shiota have taught the technique to nearly 150 scientists from 15 countries.
Cherrington earned his Bachelor of Science degree from the University of New Brunswick and his Ph.D. in Physiology at the University of Toronto. He began at Vanderbilt as a post-doctoral fellow in 1973. He was appointed assistant professor of Physiology two years later and full professor in 1982. He chaired the Department of Molecular Physiology & Biophysics from 1998 to 2007. He has received numerous awards for his research accomplishments, including the Lilly and Banting Awards from the American Diabetes Association, which he served as president in 2004-2005.
McGuinness earned his Bachelor of Science degree in Biology from the State University of New York at Stony Brook and his Ph.D. in Physiology at Louisiana State University. His career at Vanderbilt began in 1984 as a post-doctoral fellow in the Department of Molecular Physiology & Biophysics, led to an assistant professorship in the department in 1989 and full professorship in 2006. McGuinness directs the Metabolic Pathophysiology Core in the Mouse Metabolic Phenotyping Center(MMPC) and the Hormone Assay and Analytical Services Core in the DRTC.
Shiota earned his Bachelor of Science degree at Rakuno Gakuen University in Hokkaido, Japan, his doctorate in Veterinary Medicine from the Japanese Ministry of Agriculture and Forestry, and his Ph.D. in Veterinary Physiology from the University of Osaka Prefecture. He was a member of the faculty there before coming to Vanderbilt in 1994 for a postdoctoral fellowship in Metabolism. That led to a faculty position and by 2011, he was associate professor in the Department of Molecular Physiology & Biophysics.
Wasserman, who directs the MMPC, earned his Bachelor of Science degree from UCLA and his Ph.D. in Physiology from the University of Toronto. Upon graduation in 1985, he came to Vanderbilt as a research associate in the Department of Molecular Physiology & Biophysics, and was appointed full professor in 1997. He has received several national research awards.
Williams received his Bachelor of Science degree from Middle Tennessee State University. Upon graduation, he was hired by Vanderbilt as a diabetes research assistant. He currently directs the S.R. Light Laboratory and the Division of Surgical Research in the Section of Surgical Sciences, and the MMPC Animal Resources Core.
Research Enhancement Award for Development, Implementation, and/or Creation of Technology that Elevates the Research and Science of Multiple Investigators — K. Sam Wells, Ph.D., research professor of Molecular Physiology and Biophysics
Wells received his Bachelor of Science degree in Chemistry from the University of Utah, and his master’s degree and Ph.D. in Physical Chemistry from the University of New Mexico. As a postdoctoral fellow at Cornell University, he participated in the initial feasibility experiments leading to the invention of two-photon-excited fluorescence imaging. In the early 1990s, Wells developed fluorescent reagents, imaging calibration, flow cytometry standards and other applications and techniques that resulted in several commercial products and patents. Later, as a staff scientist for Bio-Rad Laboratories, he taught researchers around the country how to use non-linear-excited fluorescence imaging equipment.
In 2000, Wells was recruited by Vanderbilt as research associate professor in the Department of Molecular Physiology and Biophysics and as managing director of the Vanderbilt Cell Imaging Shared Resource (CISR). In 2009, he took over direct management of Electron Microscopy. During the past decade, Wells has managed a tenfold expansion of capital assets distributed in eight imaging labs, a better than sevenfold increase in service hours and a greater than threefold increase in the user base. Today the CISR is used by about 650 individuals from 250 different funded principal investigator labs, and provides service for NIH grants with a combined value in excess of $682 million.
In addition, Wells has provided guidance in basic and advanced imaging techniques, including rigorous analytical methodology, for hundreds of scientists at all career levels. He has conducted optical microscopy mini-courses for faculty and students. He supervises several research assistants, lab managers and research specialists and, for the past six years, has served as instructor of the microscopy module of the Vanderbilt Masters of Laboratory Investigation Degree Program. Finally, Wells is an effective research collaborator, suggesting project implementation, experimental parameters and imaging modes that have aided the success of numerous grant proposals.
