Biography

I am currently an associate research physicist at the Space Sciences Laboratory at UC Berkeley. I have a variety of research interests in the field of astrophysics, including the formation and evolution of magnetic fields in the convective envelope of stars like our Sun; the physics of magnetically driven eruptions in the solar corona (the principal drivers of space weatherhere at earth); the transport of radiation in solar and stellar chromospheres during strong flares; and the dynamic, magnetic, and energetic connection between the solar interior and atmosphere. Each section of this page contains brief (hopefully understandable!) descriptions of each project, along with some nice visualizations of both observed and simulated datasets. If you are interested in the details of a particular project, an abbreviated version of my Curriculum Vitae contains a list of some of my recent peer-reviewed journal articles.

Biography

I am a 3rd year physics graduate student working here at the lab in heliospheric radio physics in Prof. Stuart Bale’s group. In particular I’m interested in tracking radio bursts in the inner heliosphere. I also work on mission simulation and design for the CUbesat Radio Interferometry Experiment (CURIE).

I enjoy finding creative and interactive ways to visualize data.

RESEARCH INTERESTS

I am interested in plasma astrophysics from the experimental point of view. Much of the universe is in the plasma state and we are just coming to appreciate the role of plasma dynamics and magnetic fields in the large-scale evolution of astrophysical systems. However, many of the fundamental processes are poorly understood and can only be studied in a limited parameter regime in the laboratory. Examples are magnetic reconnection, collisionless shocks, plasma turbulence, and solar/stellar wind generation and evolution.

My research is focused on developing experiments to understand these processes and, in particular, how microscale, kinetic phenomena, affect large-scale plasma evolution.

I am also interested in low frequency (LF) radio astronomy, at frequencies below the ionospheric cutoff (~12 MHz); these observations need to be made from space. Signatures of solar flare electrons and CMEs dominate the dynamics at these frequencies, however the large-scale structure of the radio sky below 15 MHz remains mostly unexplored.

Our group at the Space Sciences Laboratory develops, builds, and operates space-borne experiments to study in situ the plasma processes active in astrophysical, heliospheric, and magnetospheric systems. These experiments are flown on NASA and ESA spacecraft missions and are often developed as balloon and sounding rocket payloads.

Current Projects

My group is involved with NASA’s STEREO mission to study the generation and evolution of Coronal Mass Ejection (CME) phenomena. CMEs are dramatic, large-scale solar eruptions whose triggering mechanism, evolution, and role in solar physics are largely unknown; however CMEs are thought to play a role in the helicity evolution of the solar dynamo. Several of the experiments on STEREO were designed and built at the Space Sciences Lab. Our experiments will remotely sense radio emission and energetic particles from these events, as well as thermalization and shock processes in the ambient solar wind. Opportunities exist for students to be involved in data analysis on STEREO.

Magnetic reconnection is a phenomenon that allows rapid, topological reorganization of magnetic fields in a plasma; it is the primary agent in solar flare and magnetospheric dynamics and is thought to play a role in solar/stellar wind acceleration, accretion disk physics, and other astrophysical phenomena. Our experiments on the Polar, Wind, and Cluster spacecraft have made important measurements of ion and electron diffusion and plasma turbulence related to reconnection evolution. Experimental studies of electron diffusion and wave physics are continuing.

An ongoing project is the study of electric fields, wave phenomena, and particle acceleration at collisionless shocks. Shocks are ubiquitous in astrophysics and are responsible for particle (cosmic ray) acceleration, plasma heating, and mediating flow at astrophysical boundaries. Dissipation physics, particle acceleration, and the energy budget at shocks are poorly understood. Experiments on the Cluster, Wind, and Polar spacecraft are used to study these problems.

Other important problems currently accessible to experimental progress include solar wind generation and evolution, plasma radio emission mechanisms, and plasma wave-particle interactions.

Professor Beckwith is a member of the American Academy of Arts and Sciences, a Fellow of the American Association for the Advancement of Science, and a Fellow of the California Academy of Sciences. He has served as Director of the Max-Planck-Institut für Astronomie (Heidelberg, Germany), the Director of the Space Telescope Science Institute (Baltimore, Maryland), and most recently as the Vice President for Research and Graduate Studies for the ten-campus University of California system (Oakland, California). He has been on the faculties of Cornell University (Professor of Astronomy) and Johns Hopkins University (Professor of Physics and Astronomy) prior to coming to Berkeley in 2008.

Specialty Areas

Origins of life, cosmology, star formation, planet formation

Research Interests

Professor Beckwith is interested in nature’s leap from chemistry to biology on the prebiotic Earth and how an understanding of that leap will let us infer the likelihood that life has developed elsewhere in the universe. He is investigating how non-equilibrium thermodynamic processes on a small scale may give rise to chemical reaction networks that will become self-sustaining and ultimately evolve into the life we see on Earth today.

The Gemini Planet Imager (GPI) is a new science instrument that exploits the latest generation of adaptive optics technology, coronagraphy, and detectors. We have successfully commissioned GPI at the Gemini South telescope in Chile and in 2014 we started a three-year science program called GPIES (GPI Exoplanet Survey) that will survey 600 stars for the presence of young giant planets.
