As a data scientist at Endgame, Phil develops data products that help security analysts find and respond to threats. This work has ranged from tuning a machine learning algorithm to best identify malware to building a data exploration platform for HTTP request data. Previously, he developed image processing algorithms for a small defense contractor. While earning a PhD in physics, Phil used a machine learning algorithm and the IceCube detector at the south pole to search for neutrinos from other galaxies.
