What I'm looking for

I seek a role leading technical testing and automation projects where I can standardize methodologies, mentor teams, and turn lab data into actionable insights.

I am a results-driven Senior Laboratory Engineer with over six years of experience building scalable testing methodologies and managing R&D projects in a 15,000 sq. ft. lab. I combine hands-on lab buildouts with automation and advanced analytics to produce proprietary data assets that inform editorial coverage.

At CNET Labs I directed cross-category product testing, supervised technicians, and mentored engineers while designing custom test chambers and rigs. I developed and validated automated testing frameworks for router throughput, VPN benchmarking, and robot vacuum navigation efficiency that standardized data collection across brands.

I build cross-platform software and pipelines (Linux, Windows, Mac) using Python, R, and SQL to support repeatable, shareable analyses and visualizations; I also led company-wide training on data visualization tools, increasing engagement and driving adoption. My background in chemical engineering and beverage formulation underpins rigorous QA, SOP development, and experimental design.

I am motivated by roles that let me lead technical projects, improve testing standards, and translate complex data into actionable insights that support product strategy and trusted editorial or stakeholder decision-making.
