Carlos Paz-Soldan’s research interests are motivated by the desire to solve the scientific and technological challenges standing in the way of harnessing controlled fusion energy on earth.

Research Interests

plasma physics, magnetically confined plasmas, plasma stability and control, fusion energy technologies

Prof. Carlos Paz-Soldan’s work focuses on controlling the transient off-normal events that can prevent the safe and reliable operation of the tokamak magnetic fusion reactor configuration. He is interested in advancing the physical basis of various instability phenomena as well as developing the fusion technologies necessary to deploy feasible actuators to achieve control.

Paz-Soldan joined the Columbia Applied Physics and Applied Mathematics Department in 2021. Prior he was a staff scientist in the Magnetic Fusion Energy Division at General Atomics, where he advanced the research program of the DIII-D National Fusion Facility as well as other experiments worldwide.  Paz-Soldan has contributed to a broad range of problems in tokamak operation, stability, and control. These include: understanding the interaction of tokamak plasmas with non-axisymmetric fields used to control core and edge instabilities; the measurement and control of relativistic electron populations; and the conceptualization and design of novel actuators for transient control. He earned his B.Sc.E. from Queen’s University at Kingston, Canada in 2007 and his Ph.D. from the University of Wisconsin-Madison in 2012. For his work at Wisconsin, Dr. Paz-Soldan was awarded the Marshall N. Rosenbluth Outstanding Doctoral Thesis Prize of the American Physical Society in 2013.
