lasers.llnl.gov Part of the senior management team overseeing and supporting NIF&PS programs and the workforce to produce transformational capabilities and results for the NNSA and US national security, including the historic achievement of fusion ignition on the NIF for NNSA's Stockpile Stewardship Program. Part of LLNL's institutional team on the development and implementation of new business practices Laboratory wide, such as for performance and salary management. Senior Advisor to LLNL's Inertial Fusion Energy Institutional Initiative which is building on ignition for enduring energy and climate security.

Oversaw and supported the ramp up of multiple programs in the NIF&PS Directorate centered on advanced laser development merged with LLNL’s experimental High Energy Density Science (HEDS) expertise to create new capabilities for NNSA and US national security, including new petawatt lasers for extreme materials science and inertial fusion energy R&D. Oversaw the development and sustainment of NIF&PS' HEDS and Advanced Photon Technologies (APT) workforce.

Led and supported the MagNIF effort to add magnetic field capability to NIF experiments, culminating in first NIF implosion experiments with embedded magnetic fields demonstrating signficant fusion yield enhancement. Although current NIF fusion ignition shots do not require magnetic fields, implosions augmented with magnetic fields could provide more advanced target options for future ignition designs.

Led, managed, and supported the 500 engineers, scientists, and technicians of the Laser Systems Engineering and Operations Division, in support of programs under the National Ignition Facility and Photon Science Directorate.

Recipient of the DARPA Superior Public Service Medal in 2019, finalist for the 2017 Samuel J. Heyman Service to America Medal, and DARPA's Program Manager of the Year in 2016 for creating and leading high-impact programs and teams in the Defense Sciences Office:SIGMA: Cost-effective, practical, continuous city- and region-scale nuclear threat monitoring via automated and intelligent sensor networks. System demonstrated more than an order of magnitude increase in performance compared with state-of-the-art, as well as scalability to many 1000's spectroscopic sensors. The system has been tested, deployed, and made operational in multiple areas:https://www.darpa.mil/news-events/2016-08-23https://www.darpa.mil/news-events/2016-10-11https://www.darpa.mil/news-events/2017-03-01https://www.darpa.mil/news-events/2020-09-04SIGMA+: Led a team of DARPA program managers to expand SIGMA and demonstrate that automated, distributed networks of sensors, combined with automated analytics and insights from social science, can be deployed and practically scaled to detect the full spectrum of Chemical, Biological, Radiological, Nuclear, and Explosives (CBRNE) threats:https://www.darpa.mil/news-events/2018-02-20https://www.darpa.mil/news-events/2019-04-30ICONS (Intense and Compact Neutron Sources): Highly portable, intense neutron sources for in-the-field, high-resolution neutron and x-ray imaging ACCESS (Accelerated Computation for Efficient Scientific Simulation): Foundational technologies and approaches for scientific computing beyond Moore's law

Developed and led multiple efforts as principal investigator in the area of compact accelerators, pulsed plasma radiation sources, and their associated national security applications. Hired, assembled and led multidisciplinary teams to achieve project objectives. Delivered leading results and innovations resulting in more than 30 refereed publications as well as multiple patents.

Proposed and executed RF heating studies on Alcator C-Mod, a DOE magnetic fusion tokamak experiment. Achieved first direct core measurements of the ICRF heated proton energy distribution in fusion reactor relevant C-Mod plasmas via a novel multichannel compact neutral particle analyzer. Revealed off-axis peaking of these fast protons and provided physical understanding of this phenomenon via detailed comparisons of data with leading full-wave/Fokker-Planck solvers.Conducted neutronics, thermal, and fuel cycle design studies of tokamak based fusion-fission reactors.
