Advisory Board


Dr. Sanjeev Mukerjee, Chairman of the Advisory Board
Dr. Sanjeev Mukerjee is a Professor in the Department of Chemistry and Chemical Biology (Northeastern University); where he has been since September of 1998. He also heads the newly created center for Renewable Energy Technology at Northeastern University and its subset the Laboratory for Electrochemical Advanced Power (LEAP). His research on charge transfer dynamics at both two and three dimensional electrochemical interfaces encompasses materials development, in situ synchrotron spectroscopy and electro-analytical methods. In addition, new computational initiatives are in progress involving both molecular modeling and simulation of multiple electron scattering in the context of in situ synchrotron XANES method. Peer reviewed publication currently number 106, with an H-factor of 45. The current projects in the group include materials development for new electrocatalysts, polymer electrolyte membranes and high energy density (and capacity) cathode materials for aqueous and non-aqueous storage cells. Fundamental understanding of structure property relationships are in concert with applications. In this context two startup companies which the group helped found, Encite Corp, Burlington, MA and Protonex Corp., Westboro, MA are notable. In addition partnership with De Nora, and BASF, Proton Onsite, Ford Motor Co., Advent North America and Automotive Fuel Cell Corporation (Canada) are ongoing for developing a number of fuel cell and electrolyzer technologies. Federal funding comes from the Army Research Office, Department of Energy, National Science Foundation, Air Force Office of Scientific Research and National Institute of Technology-Advanced Technology Program.
