Lorenzo Sironi

Lorenzo Sironi is an Associate Professor in the Department of Astronomy at Columbia University and Director of Graduate Studies in Astronomy. His research focuses on high-energy astrophysics and plasma processes in extreme environments, such as relativistic shocks, magnetic reconnection, and turbulence. He holds a PhD from Princeton University (2011) and has held postdoctoral positions at Harvard and Columbia. He leads a dynamic research group investigating plasma astrophysics, with notable awards including the 2019 Sloan Fellowship in Physics and the 2020 Cottrell Scholar Award.

His work bridges theory, simulations, and observation, addressing topics like particle acceleration in astrophysical shocks, neutrino production in black hole coronae, and the dynamics of relativistic jets. Recent studies include machine learning applications to plasma turbulence and the role of magnetic reconnection in nonthermal emission. His group's research has implications for understanding cosmic rays, gamma-ray bursts, and AGN activity.

• Education: PhD in Astrophysical Sciences, Princeton University (2011)
• Research Highlights: Relativistic plasma turbulence, magnetic reconnection in black hole systems, and particle acceleration mechanisms.

Notable collaborations include studies of intrabinary shocks in spider pulsars and the development of advanced particle-in-cell simulations for modeling multimessenger emission. His work has been supported by grants such as the NSF Multimessenger Plasma Physics Center (MPPC).

Labs/Teams: Leads a research group specializing in computational astrophysics and plasma simulations, fostering interdisciplinary approaches to high-energy astrophysical phenomena.
