John Heuser

John E. Heuser (born August 29, 1942) is an American Professor of Biophysics in the department of Cell Biology and Physiology at the Washington University School of Medicine as well as a Professor at the Institute for Integrated Cell-Material Sciences (iCeMS) at Kyoto University.

Heuser created quick-freeze deep-etch electron microscopy (a variant of cell unroofing), a pioneering technique that lets biologists take detailed pictures of fleeting events inside living cells. For decades, Heuser has used this technique to capture details of the molecular mechanisms that underlie many basic biological activities, including nerve cell signal transmission, muscle contraction, and most recently, the fusion of viruses with cells during the spread of infection. He compares quick-freeze deep-etch electron microscopy to using a stroboscopic flash to freeze the action in a photograph. To make it possible to image the frozen sample with an electron microscope, Heuser adds an ultra-thin film of metallic platinum that molds snugly against the sample's frozen surface contours. He and others in his lab have worked to make the equipment and procedures necessary for this process available to researchers around the world. Currently Heuser has patents pending on Washington University's behalf for even more advanced versions of his quick-freezing machines.

Heuser graduated magna cum laude from Harvard Medical School in 1969 and joined the Washington University faculty as a professor of biophysics in 1980. He is currently associate editor of the ''Journal of Neurocytology'' and previously served as associate editor of the ''Journal of Cell Biology''. His curriculum vitae lists over 200 scientific publications. He was elected as a fellow of the American Academy of Arts and Sciences class of 2005 and of the American Association for the Advancement of Science in 2007. Heuser was also elected as a member of the National Academy of Sciences in 2011. Provided by Wikipedia
