Question: Who is the synthetic organic chemist that headed up group who designed the nanocar molecule in 2005?

Context paragraphs:
Paul Grieco: Paul Grieco is an organic chemist at Montana State University.  His research focuses on the total synthesis of natural products and the study of solvent effects in various organic reactions.  He has received several awards for his work, including the American Chemical Society (ACS) Arthur C. Cope Scholar Award in 1990 and the ACS Award for Creative Work in Synthetic Organic Chemistry in 1991.  Among his contributions are two name reactions: the Grieco elimination and the Grieco three-component condensation.

The Ryoji Noyori Prize: The Ryoji Noyori Prize was established by the Society of Synthetic Organic Chemistry, Japan in 2002 to commemorate Ryōji Noyori winning the 101st Nobel Prize in Chemistry as well as the 60th anniversary of the Society of Synthetic Organic Chemistry.  The prize is given "to recognize and encourage outstanding contributions to research in asymmetric synthetic chemistry defined in its broadest sense."  The prize is sponsored by Takasago International Corporation.

Birch reduction: The Birch reduction is an organic reaction which is particularly useful in synthetic organic chemistry.  The reaction was reported in 1944 by the Australian chemist Arthur Birch (1915–1995) working in the Dyson Perrins Laboratory in the University of Oxford, building on earlier work by Wooster and Godfrey in 1937.  It converts aromatic compounds having a benzenoid ring into a product, 1,4-cyclohexadienes, in which two hydrogen atoms have been attached on opposite ends of the molecule.  It is the organic reduction of aromatic rings in liquid ammonia with sodium, lithium or potassium and an alcohol, such as ethanol and "tert"-butanol.  This reaction is quite unlike catalytic hydrogenation, which usually reduces the aromatic ring all the way to a cyclohexane.

James Tour: James M. Tour is a synthetic organic chemist, specializing in nanotechnology.  Dr. Tour is the T. T. and W. F. Chao Professor of Chemistry, Professor of Materials Science and NanoEngineering, and Professor of Computer Science at Rice University in Houston, Texas, United States.

Usha Ranjan Ghatak: Usha Ranjan Ghatak (1931–2005) was an Indian synthetic organic chemist, stereochemist and the director of the Indian Association for the Cultivation of Science (IACS).  He was known for his contributions in developing novel protocols of stereoselective synthesis of diterpenoids.  He was an elected fellow of the Indian Academy of Sciences and the Indian National Science Academy.  The Council of Scientific and Industrial Research, the apex agency of the Government of India for scientific research, awarded him the Shanti Swarup Bhatnagar Prize for Science and Technology, one of the highest Indian science awards, in 1974, for his contributions to chemical sciences.

Marie Mercury Roth: Marie Mercury Roth is an American synthetic organic chemist.  She was the first female Ph.D. candidate at the chemistry department of University of Wisconsin–Madison, where she worked with William Summer Johnson.  She received her Doctorate of Philosophy in 1951 for the "Application of the Favorskii rearrangement to the problem of angular methylation".

Mikael Bols: Mikael Bols (born July 28, 1961) is a synthetic organic chemist who is mainly known for his work on carbohydrates and artificial enzymes.

Nanocar: The nanocar is a molecule designed in 2005 at Rice University by a group headed by Professor James Tour.  Despite the name, the original nanocar does not contain a molecular motor, hence, it is not really a car.  Rather, it was designed to answer the question of how fullerenes move about on metal surfaces; specifically, whether they roll or slide (they roll).

Harry Stone Mosher: Mosher attended Willamette University in Salem, Oregon, where he received a bachelor's degree in chemistry in 1937.  He went on to Oregon State University, where he earned a master's degree in 1938.  He then returned to Willamette to teach for one year.  In 1939, he continued his graduate work at Pennsylvania State University under the mentorship of Frank C. Whitmore, a renowned organic chemist.  In 1942, Mosher completed his PhD in organic chemistry.  He remained at Pennsylvania State as an assistant professor, supervising research on synthetic anti-malarial drugs for the National Research Council and the production of DDT with the War Production Board.  In 1944, Mosher married Carol Walker, a fellow chemistry graduate student at the university.  Three years later, Mosher accepted an assistant professorship at Stanford University in the Department of Chemistry, and he and his wife moved to California for the position.  That same year his wife Carol joined the staff of the Stanford Research Institute, later becoming senior organic chemist.

Atul Kumar (chemist): Atul Kumar is a synthetic organic chemist, Sr.  Principal Scientist at Academy of Scientific and Innovative Research (AcSIR) and the Central Drug Research Institute (CSIR-CDRI) at Lucknow, India and a Dean at National Institute of Pharmaceutical Education and Research, Raebareli.
