• Radiation Protection project lead for CUIR (Critical Utilities Infrastructure Revitalization), a multi-year, multi-contractor infrastructure project — coordinating project readiness, work planning, dose forecasting, staffing, scheduling, and cost estimating, contractor training requirements, work controls, field communications, and four-week lookahead planning.
• Program owner for four site-level programs — Radiation Generating Devices (RGDs), Radiological Training, Radiological Work Permits (RWPs), and Search & Survey — covering program operations, recurring deliverables, stakeholder coordination, compliance, and process improvement.
• Leading modernization of SLAC's electronic Radiological Work Permit system, migrating from an internally developed database to the Mirion eRWP platform and translating technical requirements, existing workflows, user roles, permissions, and operational needs into the new system.
• Leads end-to-end planning and field execution for contractor-performed industrial radiography projects — coordinating documentation, job-specific work authorization, personnel, equipment, work locations, road closures, boundaries, and field controls — with on-site oversight and authority to authorize work, pause operations, and approve removal of radiological boundaries at completion.
• Manages RWP program operations for 60+ active permits under quarterly renewal — coordinating review, approval, issuance, closeout, and retirement — while personally supporting higher-complexity, job-specific permits from planning through field execution.
• Oversees compliance and operational readiness for 100+ Radiation Generating Devices (≈85 active at any time); built and deployed a SharePoint/Power Automate compliance tracker for 100+ records, automating reminders for leak tests and operator training expirations.
• Built and deployed a CUIR project dashboard used in daily leadership meetings, consolidating dose, survey, workforce, and control data into daily and weekly metrics across 1,000+ personnel-day entries and 60+ active project days.
• Presents CUIR dose forecasts, work controls, training plans, and project readiness to ALARA Committee stakeholders and department leadership, supporting approval and execution of major project work.
• Maintains radiation worker training compliance for approximately 750 SLAC personnel site-wide; trained and onboarded roughly 160 workers for CUIR during peak project periods.
• Serves as Area Health Physicist for accelerator sectors 0–10 and 20–30, reviewing radiological surveys and postings, monitoring accelerator operations and maintenance activities, and reporting area readiness and outstanding work to leadership.

• Prepared dose investigation reports and performed audits, technical peer reviews, and analytical assessments in a highly regulated naval nuclear environment.
• Led implementation of Varskin+ skin-dose calculation software across Naval Nuclear Laboratory Radiation Health departments, coordinating adoption of a standardized technical tool and workflow.
• Supported environmental radiation monitoring, medical qualification checks, whole-body counting, gamma spectroscopy, dose assessment, and emergency response activities.

• Analyzed P&IDs, equipment data, drawings, and vendor documentation to support facility calculations.
• Evaluated overpressure scenarios, developed process flow diagrams, and supported Process Hazard Analyses using PHA Pro.
