Dr. Leonid Nichman

Postdoctoral Research Fellow | nichman@bc.edu


Dr. Leonid Nichman has received his M.Sc. degree in chemistry and materials science from the physical-chemistry department of Tel Aviv University where he studied radicals above flat flames with laser spectroscopy and used pulsed lasers for ablation and propulsion under the supervision of Prof. Sergey Cheskis and Dr. Valery Bulatov. In his further postgraduate studies in Prof. Zeev Zalevsky's group at Bar Ilan University he used electron beam charge deposition on insulators, followed by rearrangement of deposited nanoparticles to fabricate nano-wires for devices.
Later, Dr. Nichman has been awarded a Marie Curie fellowship in the School of Earth, Atmospheric and Environmental Sciences (SEAES) at the University of Manchester, where he received his PhD in cloud-microphysics under the supervision of Prof. Thomas Choularton and Prof. Martin Gallagher. In this period Dr. Nichman took an active part in the CLOUD project at CERN.
In his career Dr. Nichman was employed in the private sector for almost 5 years as a R&D Materials Chemist at Landa Laboratories and Landa Corporation. He was involved in many projects such as Green energy research, Printing research, Graphene Oxide production and others.
Currently, Dr. Nichman is a postdoctoral research fellow at the department of chemistry in Boston College. The group, lead by Prof. Paul Davidovits, studies aerosol chemistry and physics in close collaboration with Aerodyne research Inc. and MIT.
