As a Staff Data Scientist, I exercise my advanced data science expertise designing, developing, and deploying models and analysis for approximately 70% of the time on specific high impact projects, and perform technical project management and consulting for of data-driven initiatives about 30% of the time. Sometimes this split is 50%-50% if the group has lots of new modeling and analysis tasks for a new initiative that need to be technically planned out and verified. Job Responsibilities:- Advanced Implementation Responsibilities: * Actively researching, developing, implementing, and inventing the most advanced algorithms/models/analysis on a select few projects * Participating in design reviews and recommend improvements * Assisting in risk assessment and mitigation activities * Working with other data scientists in planning, prioritizing and executing assigned tasks within deadlines- Leadership Responsibilities: * Leading a team of 8 data scientists on technical aspects of data science initiatives * Conducting strategic technical data science planning * Recommending new technologies to ensure quality and productivity- Communication Responsibilities: * Sharing expertise and insight with other data scientists * Motivating data science staff and fostering collaboration * Writing technical papers on data science work being done * Writing technical and non-technical blogs on work being done

I was previously researching machine learning for irregular time series data sets, with particular validation against electronic health record data. Irregular time series can also be thought of "event based" systems, where events are occurring over time at different intervals. Examples of problems that fit this domain include log based event analysis, social media events (think tweets), operating system events, health record events, market trading events, and many others.Overall I'm interested in machine learning, but have picked up a fancy for trying to develop new methods for reasoning about data that is generated over time. I am currently working with Dr David Page's research group located in the Wisconsin Institute of Discovery.

I developed many statistical prediction models for the analysis of health events, statistical analysis of latent data patterns, and designed pipelined machine learning systems that scale for large numbers of simultaneous users. My work included both the practical application of machine learning that dealt with model selection, feature engineering, model evaluation, and algorithmic efficiency, as well as the development of novel theoretical machine learning methods for increasing performance considering specialized domain centric constraints.I also worked on various software, hardware, and firmware projects. Most of these dealt with aspects of health monitoring, and new health tracking technology. This includes developing new software algorithms for quantifying health, development of wearable embedded systems, and development of Android applications for interfacing with health devices.

Research Project Results:***Custom Deep CNN and optimization method, Keras/Theano, Bloodless Blood-Glucose prediction model with 98% prediction accuracy***Feature importance analysis using random forests, LASSO, and other feature selection based methods for better insight into the problem domain.***Unsupervised analysis such as meal information clustering, and time series similarity analysis***Scalable, AWS based deep net model that could be trained with AWS based graphics card clusters***Android mobile phone and smart watch application for gathering data, communicating with Deep CNN model, and displaying user glucose level status.***Scalable AWS based micro services for managing user data, and predictive computations.My research work for the Trustworthy Data Engineering Lab centered around mining meaningful health metrics from wearable health platforms, and developing models to relate them to clinical health metrics. During my time with the lab, I developed a glucose peak prediction system using advanced machine learning methods, which makes predictions using only common wearable sensors. The system is an end to end solution, including services running in the cloud for data manipulation and ml model access, a mobile front end for displaying and gathering data, and a smart watch for displaying prediction updates.My work in general included the use of various clustering, statistical modeling, feature learning, data mining techniques, and the development of scalable machine learning algorithms. Most of the code was implemented using python, and includes the use of Scipy, Pandas, Scikit-Learn, Theano, and Spark.

As a student at UC, I studied the field of computer engineering. This includes not only taking classes and participating in clubs, but actively researching new fields of technology. Much of my research focused on sweat sensing devices, mobile health software applications, and mobile health analysis algorithms.Note that UC's engineering program is 5 years instead of 4 due to the required 5 semesters of COOPs. The extra year to graduate in exchange for so much industry experience is well worth it, and in my opinion puts UC's engineering program light-years ahead of most academic institutions which rely on student internships for exposure to industry.
