Three Stanford scholars tapped as AAAS fellows

Three Stanford scientists have been named fellows of the American Association for the Advancement of Science (AAAS), an honor bestowed upon members of the association by their peers.

The Stanford scholars join 500 other newly elected fellows of the world's largest general scientific organization.

Fellows are chosen on the basis of efforts that are scientifically or socially distinguished. The new fellows will be honored Feb. 19 during the AAAS Annual Meeting in Washington, D.C.

The fellows are:

Hongjie Dai, the J.G. Jackson and C.J. Wood Professor of Chemistry. Dai was selected for "pioneering contributions to the field of carbon nanotubes and graphene-based nanomaterials." Dai's research focuses on solid-state and soft biological materials. Dai has explored using single-walled carbon nanotubes as delivery vehicles for cancer chemotherapy, successfully increasing the proportion of medication entering tumor cells. That makes a given dose of medication both more effective at killing tumor cells and less likely to cause side effects in normal tissue. He has published work on producing large quantities of uniform graphene nanoribbons more quickly and easily than could be done previously, by slicing open carbon nanotubes. Graphene is a form of carbon derived from graphite. Dai also has explored using graphene nanoribbons in "field effect transistors" – a critical component of computer chips – that can operate at room temperature rather than at extremely cold temperatures, as other graphene transistors require.

David Relman,professor of infectious diseases and of microbiology and immunology at the School of Medicine. Relman was selected for his "distinguished contributions in the areas of human-microbe interactions and human microbial ecology." He has developed methods that have enabled him to detect thousands of species of bacteria that live inside all of us. He is also working with colleagues to understand the various functions of these microbes. His experiments and ideas were key to establishing the Human Microbiome Project, a $115 million, five-year government-funded effort launched in 2007 to explore the microbial communities occupying different parts of the body. Relman is the Thomas C. and Joan M. Merigan Professor and is also chief of the infectious diseases division at the Veterans Affairs Palo Alto Health Care System.

Jon Krosnick, professor of communication, political science and psychology, by courtesy. Krosnick was selected for his "outstanding research in political psychology, leadership of the American National Election Studies, and innovative contributions to survey methodology, including assessment of alternative modes of survey administration." Krosnick was a principal ANES investigator from 2005 to 2009. In addition to his work on survey research and polling methods, Krosnick focuses on attitude formation, change and effects, and the psychology of political behavior. Krosnick is the Frederic O. Glover Professor in Humanities and Social Sciences and is also a senior fellow at the Woods Institute for the Environment, by courtesy.
