- Leonidas Bleris, a graduate student in Electrical and Computer Engineering, working under the supervision of Prof. Kothare, has been selected as recipient of the National Academies' Christine Mirzayan Science and Technology Policy Graduate Fellowship Program. This Fellowship is sponsored by the National Academy of Sciences and its constituent organizations, National Academy of Engineering, Institute of Medicine, and the National Research Council (the National Academies). Bleris will spend ten weeks as a policy fellow in Washington, D.C., with the Board on Mathematical Sciences and Their Applications in the Division of Engineering and Physical Sciences. This Fellowship program of the National Academies is designed to engage graduate students in the analysis that informs the creation of science and technology policy, and to familiarize them with the interactions of science, technology,and government. As a result, students develop essential skills different from those attained in academia and make the transition from being a graduate student to a professional.
The program is very competitive with generally less than 10% of applicants being selected in any given year.
