Fan Guo

Staff Scientist, Los Alamos National Lab

Fan Guo is a staff scientist in T-2. He received his PhD in the University of Arizona in 2012. He then became a postdoc in Los Alamos National Laboratory before converted to a staff position in 2016.

Fan Guo’s research focuses on theoretical understanding and computer modeling of fundamental processes relevant to astrophysical, space and laboratory plasmas including particle acceleration and plasma energization, magnetic reconnection, shocks, and turbulence. He has used fully kinetic, hybrid (kinetic ions, fluid electrons), particle transport and MHD simulations to model those processes and built analytical theories. He has published more than 110 papers as the first author or a contributed author with more than 4000 citations and H index 36. He has given more than 70 invited presentations, seminars, and colloquia in various conferences, universities and institutes. In addition, he has experience mentoring numerous postdocs and students.

Science Areas



Fan is elected to lead the APS topical group of plasma astrophysics (GPAP).

Nov. 10, 2023 Xiaohang Chen has successfully obtained his PhD at the University of Arizona. He plans to start a postdoc position at the University of Michigan. Congrats, Dr. Chen!

Fan Guo gave an invited talk in the APS-DPP meeting in Denver Colorado, titled "Are Reconnection X-points Important for Nonthermal Particle Acceleration in Relativistic Magnetic Reconnection?"  link 

A new paper discuss nonthermal particle acceleration in relativistic reconnection. It proposes a semi-analytical model for systematically investigating nonthermal particle acceleration in reconnection. The energy spectra are well determined by particle injection, acceleration, and escape processes.  link 

A new review paper on magnetic reconnection and associated particle acceleration in high-energy astrophysics link 

A white paper titled 'Advancing Theory and Modeling Efforts in Heliophysics' has been submitted to the 2024 Heliophysics Decadal Survey link
