Scientist. Builder. Physics PhD; eight years as a lead applied scientist at Amazon. I work on hard problems with messy data and ship something useful at the end.
About
Physics PhD (Maryland), trained at Chicago. Started in gravitational-wave data analysis for LIGO — post-Newtonian theory, matched-filter search pipelines, co-leading one of the flagship searches.
Pivoted to cybersecurity at Sqrrl, a Boston startup spun out of NSA threat-hunting work, where I built detection and analytics on real customer data at enterprise scale. Sqrrl was acquired by Amazon, and I stayed on for eight years as an applied scientist — one of four scientists who launched Amazon Detective, then working in the Security Analytics and AI Research (SAAR) team as lead scientist on major Detective feature additions and the relaunch of AWS Security Hub.
I like problems where the data is messy, the answer matters, and the work has to actually run in production.
Currently searching for my next problem to tackle.
