Applied Scientist II @ Amazon Applied Machine Learning Scientist on the Smart Home Machine Learning team at Amazon. I design and build machine learning services that run at scale. From November 2017 to November 2019 (2 years 1 month) Greater Seattle AreaResearch Assistant @ Brown University I performed wet lab experiments in Alex Brodsky's cancer genomics lab. From 2006 to 2008 (2 years) Sr. Machine Learning Engineer @ Phyn Phyn is a startup developing sensors that are installed at a single point in plumbingsystems. My team built a Python/AWS machine learning platform to characterizewater use and identify leaks from streaming sensor data in real time.Personal Accomplishments:• Reduced the number of false positive leak alerts by 90% by developing a systemthat continuously learns building-specific usage patterns from user responses to leak alerts • Led the development of algorithms to classify water usage into fixture categories• Designed and drove implementation of the serverless software architecture for feature extraction and fixture classification• Led the code integration, testing, and deployment of algorithms to AWS cloud services From November 2016 to November 2017 (1 year 1 month) Seattle, WAPhD, Biomedical Informatics @ Stanford University Developed broad technical skills in big data computing, applied statistics, and machine learning. My primary application domain was biology and medicine.I built an open-source method for analyzing underpowered genome-wide data using a network-based approach that identifies clusters of concentrated signal in a node- and edge-weighted input graph.

From 2008 to 2010 (2 years) Senior Applied Scientist @ Amazon I manage a team of engineers, applied scientists, and data scientists in Smart Home Machine Learning. We focus on ranking, recommendation, real-time contextual embeddings, and deep insights into product data.My expertise is in big data processing (distributed computing, Spark), problem framing, experimental design, deep learning NLP techniques, and personalized behavioral models that run at scale.
