X-ray and Neutron Techniques for Nanomaterials Characterization

Dr. Challa S.S.R. Kumar is currently with Harvard University as a Managing Director. He was previously the Director of Nanofabrication and Nanomaterials at the Center for Advanced Microstructures and Devices at Louisiana State University in Baton Rouge, USA. He is also President and CEO of Magnano Technologies and has some years of industrial R&D experience working for Imperial Chemical Industries and United Breweries. His main research interests are the development of novel synthetic methods, including those based on microfluidic reactors, for the synthesis of multifunctional nanomaterials. Dr. Kumar is the winner of the 2006 Nano 50 Technology Award for his work in magnetic-based nanoparticles for cancer imaging and treatment. He is currently the Editor-in-Chief of the international journal “Nanotechnology Reviews”. He has been editor and author of several books and journal articles, and the founding editor of the Journal of Biomedical Nanotechnology.
