I am a Director of Data Science in payment integrity for commercial clients at Optum, a part of UnitedHealth Group. This means that I help create models to detect and help prevent fraud, waste, abuse, and error in medical billing for large healthcare clients. Since labeled data can be limited, I am interested in combining unsupervised, semi-supervised, and supervised methods to achieve the best possible results. More generally, I am interested in solving urgent, real world problems by applying state-of-the-art machine learning algorithms, inventing them when needed... One recent project was the creation of a supervised model that led to tens of millions of dollars in savings. In other work, I modernized a large legacy code base consisting of tens of thousands of lines of PL/SQL code by creating a modern Python and PySpark implementation. I also created a real-time version of the model by breaking out the computation into periodic computations and real-time look-ups. I have planned and..
