Prof. Uzdensky leads the Theoretical Plasma Astrophysics Group at CU. His current research focuses on 3 main areas: (1) Dynamics, nonthermal particle acceleration, and radiation signatures of relativistic collisionless magnetic reconnection and turbulence, with applications to pulsar magnetospheres and pulsar wind nebulae, and to blackhole accretion disks, coronae, and jets. (2) Plasmoiddominated regime of magnetic reconnection in large systems and its onset , in both resistive MHD and collisionless plasmas. (3) Magnetic reconnection and other plasma processes in astrophysical radiationdominated environments, a new frontier pioneered by D. Uzdensky, important for understanding magnetar flares and gammaray bursts. He also works on fundamental aspects of magnetic reconnection, on intermittency of energy dissipation in plasma turbulence, and on waves and instabilities in quantum plasmas.
