Overview Welcome to our group's home page. We work on a broad range of problems, primarily involving transport processes by electrons, phonons, photons, and fluids. We seek to solve problems with high importance to applications in energy transport, conversion, and storage, that are relevant to major industrial segments (aerospace, micro/nanoelectronics, sensors).Some topics and methods of our research are summarized in the following graphic. - Tim Fisher   James G.

Information for Prospective Students

Our research group is characterized by a passion for discovering, explaining, and developing new knowledge through persistent effort intelligently applied. Students seeking a research position with us are encouraged to review the admission guidelines provided by Purdue’s Mechanical Engineering Graduate Program. Qualified students should then review the other pages of this website to identify specific research topics of mutual interest. These topics should be highlighted in any correspondence and in application materials. Interested students would also benefit from studying the materials contained in my online nanoHUB-U course, Thermal Energy at the Nanoscale, which can be taken in self-paced mode without a registration fee (i.e., free).

India-US Joint Networked Centre

I also serve as an Adjunct Professor at the International Centre for Materials Science (ICMS), a companion organization to the Jawaharlal Nehru Centre for Advanced Scientific Research (JNCASR) in Bangalore, India. A new Joint Networked Centre on Nanomaterials for Energy established among partners JNCASR, Purdue, and GE Global Research (Bangalore) fosters ongoing collaborative research and exchanges of students and postdocs between ICMS/JNCASR, GE and the Birck Nanotechnology Center. The Joint Centre is sponsored by the Indo-US Science and Technology Forum. This effort seeks to harness the promising potential ofnanomaterials to address global energy challenges. For examples of the types of activities involved, please refer to a recent review paper, a workshop report posted on nanoHUB, and the Joint Centre's website.
