Lead Principal Investigator, NSF Center for Nanothread Chemistry

Pennsylvania State University

Professor John Badding received his B.S. from Manhattan College in 1984 and his Ph.D. from the University of California, Berkeley in 1989. He was a Carnegie Postdoctoral Fellow at the Geophysical Laboratory in Washington DC, working with Dave Mao and Russell Hemley.  Now he is Professor of Chemistry, Physics, and Materials Science and Engineering at Pennsylvania State University, USA and the author of over 200 publications. Badding is a materials and solid-state chemist whose research focuses on using high pressures to synthesize or characterize nanomaterials. Because of their unusual properties and unprecedented chemical structures, these materials have applications in telecommunications, in photovoltaic solar technology, and in high-strength materials. His work with optical fibers synthesized at high pressure has the potential for technological impact by creating tunable infrared lasers with unprecedented power, fiber-based electronic devises, and solar fabrics. In 2014 Badding and his research team reported the discovery of carbon nanothreads, a new type of tetrahedrally bonded one-dimensional carbon nanomaterial. He has received awards from the Packard Foundation, the US National Science Foundation, and Pennsylvania State University.

His name appears on a blackboard in the movie Fat Man and Little Boy, if you know where to look.

Elizabeth A. Elacqua

Assistant Professor of Chemistry

Pennsylvania State University

Professor Elizabeth Elacqua was born and raised in upstate New York, and received her B.S. Degree in Chemistry and Biology from LeMoyne College (Syracuse, NY) in 2006.  There, she conducted research focused on the synthesis of porphyrins as nitrogenase mimics, as well as on the total synthesis of natural products such as polyphenolic stilbenoids.  After spending a year at SUNY College of Environmental Science and Forestry working in the lab of Dr. Israel Cabasso at the Michael Szwarc Polymer Research Institute, she ventured to the University of Iowa for graduate school.  At Iowa, Beth worked at the interface of solid-state chemistry, supramolecular chemistry, organic synthesis, and crystal engineering in the research group of Leonard R. MacGillivray, and received her Ph.D. in 2012.  After graduation, Beth headed back to the great state of New York where she started as a Postdoctoral Research Associate at New York University working alongside Marcus Weck.  At NYU, Beth utilized her background in supramolecular chemistry and crystal engineering to work on developing β-sheet-mimicking telechelic polymers for self-assembly, as well as designing reversibly-assembling colloidal matter. 

Roald Hoffmann

Frank H.T. Rhodes Professor of Humane Letters

Cornell University

“Applied theoretical chemistry” is the way Professor Roald Hoffmann likes to characterize the particular blend of computations stimulated by experiment and the construction of generalized models, of frameworks for understanding, that is his contribution to chemistry. The pedagogical perspective is very strong in his work.

Notable at the same time is his reaching out to the general public; he participated, for example, in the production of a television course in introductory chemistry titled “The World of Chemistry,” shown widely since 1990. And, as a writer, Hoffmann has carved out a land between science, poetry, and philosophy, through many essays and three books, Chemistry Imagined with artist Vivian Torrence, The Same and Not the Same and Old Wine (translated into six languages), New Flasks: Reflections on Science and Jewish Tradition, with Shira Leibowitz Schmidt.

Hoffmann is also an accomplished poet and playwright. He began writing poetry in the mid-1970s, eventually publishing the first of a number of collections, The Metamict State, in 1987, followed three years later by Gaps and Verges, then Memory Effects (1999), Soliton (2002), and most recently, in Spanish, Catalista. He has also co-written a play with fellow chemist Carl Djerassi, entitled Oxygen, which has been performed worldwide, translated into ten languages. A second play by Roald Hoffmann, Should’ve, had its initial workshop production in Edmonton, Canada in 2006.

Unadvertised, a monthly cabaret Roald runs at the Cornelia Street Caf in Greenwich Vilage, “Entertaining Science,” has become the hot cheap ticket in NYC.

Klaus Schmidt-Rohr

Prof. of Chemistry

Brandeis University

Professor Klaus Schmidt-Rohr's group studies the composition and nanoscale structure of polymer materials, nanocomposites, carbon materials, natural organic matter, and thermoelectric tellurides, using a variety of selective or two-dimensional nuclear magnetic resonance (NMR) experiments, many of which were developed by us. We have also introduced new methods for quantitative analysis of scattering data of nanostructured materials.  This dual approach has enabled us to “solve” important aspects of the structure of the Nafion fuel-cell membrane and of the nanocomposite in bone. Based on these structural insights, we strive to understand the materials properties and sometimes propose improved synthesis conditions.

Dirk Trauner

Janice Cutler Professor of Chemistry

New York University

Professor Dirk Trauner was born and raised in Linz, Austria, studied biology and chemistry at the University of Vienna, and received his undergraduate degree in chemistry from the Free University, Berlin. He then pursued a PhD in chemistry under the direction of Prof. Johann Mulzer, with whom he moved to the University of Frankfurt and then back to Vienna. Following a stint in the Austrian Army, he became a postdoctoral fellow with Prof. Samuel J. Danishefsky at the Memorial Sloan-Kettering Cancer Center. After two great years in New York City, Dr. Trauner joined the Department of Chemistry at the University of California, Berkeley, where he rose through the ranks to become an Associate Professor of chemistry (with tenure). He was also appointed as a member of the Lawrence Berkeley National Laboratory. In the summer of 2008, he moved to the University of Munich and in March of 2017 to New York University.

The broad objective of Prof. Trauner’s research is to demonstrate the awesome power of chemical synthesis with challenging target molecules and to use it toward the establishment of synthetic biological pathways. He is well known for his pioneering contributions to Optogenetics and Photopharmacology, using synthetic photoswitches to confer light-sensitivity to a broad range of targets. The chemical tools he developed are particularly useful in neuroscience and cell biology but also hold promise as precision therapeutics. Despite his extensive forays into biology and physiology Dr. Trauner remains an organic chemist at heart, as evidenced by the synthesis (and anticipation) of more than one hundred natural products.

Dirk Trauner has been awarded the 2016 Emil Fischer Medal and the 2016 Otto Bayer Award and is a Corresponding Member of the Austrian Academy of Sciences and a Fellow of the Royal Society of Chemistry. He is also the recipient of the Kitasato Medal, the Alfred P. Sloan Fellowship, an ERC Advanced Grant, and the Austrian Chemical Society Award for the best thesis in 1997. He sits on the editorial advisory board of ACS Central Science, ACS Chemical Neuroscience, Cell Chemical Biology and Chem. His students have taken positions at many leading pharmaceutical companies and universities.
