Career Highlights:

Dr. Ajayan has been a member of the Rensselaer materials science and engineering department since 1997. He previously spent two years at the Max-Planck-Institute for Metallforschung in Stuttgart. He left there in 1997 to join the Universite of Paris-Orsay for two years, then spent three years in Tsukuba, Japan as a post-doctoral researcher for the company's fundamental research laboratory. Ajayan is an editorial board member for the following publications: Advanced Materials, Zeitschrift fur Metallkunde, TIP Revista Especialzada en Ciencias Quimco-Biologicas and Journal of Science and Nanotechnology. He won the National Science Foundation CAREER Award in 1998, the Burton Award from the Microscopy Society of America in 1997, and the Alexander von Humboldt Research Fellowship in 1995. Ajayan also was awarded the Presidential Student Award from the Electron Microscopy Society of America in 1989; the Hadfield Medal for Outstanding Metallurgist in Calcutta, India in 1985; and the Bachelor of Technology Gold Medal from Banaras Hindu University in 1985.

Research Areas:
Professor Ajayan's research interests are mainly focused on the synthesis of nanostructures, the study of their structure and properties in relation to size and confinement. He is one of the pioneers in the field of carbon nanotubes and has demonstrated several possibilities for using these quasi-one-dimensional structures as templates and molds for fabricating nanowires, composites, and novel ceramic fibers. Major goals of his research include producing macro-assemblies made of nanostructures for applications, understanding growth mechanisms of nanostructures and designing new structures and multifunctional nanocomposites. Other research interests are phase stability in metal clusters, the graphite-diamond phase transition, and growth of nanostructures under electron irradiation. He has expertise in different electron microscopy techniques.
