Jouya Jadidian has been awarded the best student paper prize at IEEE PPPS 2013, the combined 19th IEEE Pulsed Power Conference (PPC) and the 40th IEEE International Conference on Plasma Science (ICOPS) which was held June 2013 in San Francisco, CA, for the paper entitled, “Abrupt Changes in Streamer Propagation Velocity Driven by Electron Velocity Saturation and Microscopic Inhomogeneities.” [Award photo above.

The work, which was presented as an invited paper, describes a new method for characterizing the streamer propagation velocity in non-ideal liquid dielectrics to make more accurate predictions about what is likely to happen if the dielectric includes inhomogeneities of different sizes and materials, such as micro-inhomogeneities and nanoparticles.

Jouya graduated with his PhD (June 7, 2013) in LEES/RLE where he worked on reducing the size of power apparatus and medical devices by understanding the physics of electrical breakdown in liquid dielectrics. He is now a postdoctoral affiliate at MIT CSAIL.
