What I'm looking for

I seek roles leveraging my physics background and UX-quality expertise, focusing on data-driven product improvements, collaborative teams, and opportunities to influence user experience.

I am a physicist with decades of applied research and freelance work, focused on UX quality assurance, acceptance testing, and ideation. I have contributed to large engineering projects, taught and collaborated with academic peers, and produced content as an author and influencer.

My technical strengths include simulation and analysis tools, vehicle/aircraft systems familiarity, and statistical software; I deliver actionable customer-satisfaction measurements, search-engine judging, and clear, evidence-based recommendations to improve product experience.
