2011: Prof. Ken Jacobson

Prof. Ken Jacobson The winner of the Weber Award was announced during the Annual Meeting of the Biophysical Society in Baltimore, Maryland. The award has been consigned to Prof. Ken Jacobson.

Ken Jacobson is a Kenan Professor of Cell & Developmental Biology at the University of North Carolina (UNC) at Chapel Hill. He has done research in cell membrane biophysics and in cell migration for over 35 years resulting in over 170 publications in leading journals. Ken was educated at the University of Wisconsin in Physics (BS & MS) and obtained a PhD from the State University of New York at Buffalo in Biophysical Sciences in 1972. He has worked for Dow Corning Corporation, Roswell Park Memorial Institute and, since 1980, for the UNC School of Medicine.

Beginning in the early 1970s, Ken has contributed to our thinking on how the cell membrane is organized by developing methods to measure lateral mobility in the plasma membrane, primarily using technologies based on the fluorescence microscope. Such measurements tell us that the membrane is certainly not homogeneous, and they begin to tell us about the domains that exist in the membrane and their function.

Shortly after joining the UNC faculty in 1980, Ken was one of the earliest developers of digitized fluorescence microscopy and its applications to cell biology. Shortly thereafter, he and his laboratory began their study of the physical principles of how cells migrate using simple-shaped cells as a model. This work has involved developing tools to measure the traction forces the cell must apply to the surface on which it crawls. In addition, methods have been developed to perturb the molecular machinery of cell migration using laser beams to illuminate small regions of single, moving cells. Working with theoreticians, the goal is to approach a major challenge for cell biology: how to integrate myriad molecular pieces into a global understanding of motile phenomena.

For the past 20 years, Ken has also been interested in renewable energy and has been involved in a joint effort with the Research Triangle Institute, the UNC Center for Global Health and North Carolina State University to develop a small solar-powered vaccine cooler based on semiconductor thermoelectric principles to significantly reduce vaccine wastage at the end stage of the "cold chain" in the developing world.

2010: Prof. Daniel Axelrod

Prof. Daniel Axelrod The winner of the Weber Award was announced during the Annual Meeting of the Biophysical Society in Long Beach, California. The award has been consigned to Prof. Daniel Axelrod.

Professor Daniel Axelrod specializes in the development and application of novel fluorescence microscopy techniques useful to cell biologists and biochemists. He is currently a Professor Emeritus in the Dept. of Physics and Biophysics at the University of Michigan (UM Ann Arbor).

While at Michigan in 1981, he introduced total internal reflection fluorescence (TIRF) microscopy, now a popular method to view cell dynamics and single molecules at surfaces, because of its greatly reduced out-of-focus background. Subsequently, in collaboration with many excellent graduate students and other researchers, he combined TIRF with a variety of other techniques including fluorescence polarization, energy transfer, spatial and temporal correlation, and photobleaching recovery to explore a variety of problems in surface biochemical kinetics and membrane and receptor dynamics. He currently collaborates with Prof. Ron Holz in the UM Pharmacology Dept. using these combinations to help understand the dynamics of cellular secretion. Before coming to Michigan, he was a postdoc in the lab of Prof. Watt Webb at Cornell, where, in collaboration with Prof. Eliot Elson and with other researchers, he helped put fluorescence recovery after photobleaching (FRAP) on a mathematically quantitative basis and apply it to studies of cell surface receptor mobility.

Prof. Axelrod received a B.S. in Physics and in Mathematics from Brooklyn College, and a Ph.D. in Physics from the University of California at Berkeley. He is the author or coauthor of more than 100 publications, and has taught a diverse range of college courses ranging from standard physics and biophysics to graduate-level optical microscopy, the history and science of nuclear strategy, and the physics of music.

2009: Prof. Robert M. Clegg

Prof. Robert Clegg Prof. Clegg graduated from Kansas State University in 1968 and conducted his doctorial studies at Cornell University where he was awarded the Ph.D. in 1974, under the supervision of Prof. Elson; his dissertation was titled Relaxation Kinetics Applying Repetitive Pressure Perturbations. Following graduation, Professor Clegg moved to Göttingen, Germany, where he started work as a postdoctoral research associate in the Max Planck Institute for Biophysical Chemistry. In 1976, he was promoted to Senior Staff Research Associate in the Department of Molecular Biology. Dr. Clegg remained at the Max Planck Institute until he accepted a position as Professor of Physics at the University of Illinois at Urbana-Champaign in 1998. Presently, Dr. Clegg is a Professor in the Departments of Physics and Bioengineering and is on the faculty of the Biophysics Program at the University of Illinois.

Prof. Clegg research is multifaceted, though it is centered on the elucidation of multifarious molecular structures, conformational changes, thermodynamic stabilities and functions of nucleic acids and protein/nucleic acid complexes. He employs a variety of techniques, such as fluorescence spectroscopy, rapid kinetic methods and physical perturbations in order to probe the intra- and intermolecular interactions of these macromolecular structures and to understand the physical basis of their biological functions. Fluorescence resonance energy transfer (FRET) is used for mapping the three-dimensional structures of biological macromolecules. Conformational changes are followed by employing steady-state and time-resolved fluorescence techniques. Thermodynamic conditions and molecular-context features influence which structures are preferred by macromolecules.

Prof. Clegg is a pioneer in the development of full-field fluorescence lifetime-resolved microscopy (FLIM) and its applications to endoscopy for medical applications (e.g. in tumor diagnosis). These new imaging methods are applied to a variety of biological problems, such as the detection of tumor cells and their discrimination from healthy cells by identifying specific fluorescence lifetimes. These techniques introduce new opportunities for quantifying and improving the discrimination of images of fluorescence molecules in biological systems. The technology has been applied to fast kinetics studies (microsecond mixing of two fluids) and the study of photosynthesis.
