​​​

Data Science Expertise

• Led analysis and delivery of 10+ decentralized studies commissioned by technology, healthcare, government, and academic organizations as well as internal stakeholders

• Developed advanced statistical models for analysis of multimodal time-series data to characterize physiological and behavioral changes associated with illness, recovery, and other life events.

• Built pipelines for cleaning and preparing wearable (Apple Watch, Fitbit, etc.), survey, and medical data. Tasks included harmonizing data streams, designing and applying quality-control criteria, and scaling processes for datasets exceeding billions of participant-minutes. 

• Engineered novel features and metrics for physical activity, sleep, and physiological signals to support studies on health outcomes and digital biomarkers.

• Developed novel methods for visualizing, modeling, segmenting, and characterizing health outcomes in real world data

  • Extracted, cleaned, and analyzed months of minute-level wearable device data (e.g., steps, heart rate, sleep), surveys, and lab test data from 10k+ person study populations

  • Designed models to quantify and compare the burden of respiratory viral events (COVID-19, flu, RSV) on activity, physiology, and quality of life; applied methodology at US population scale to estimate the public health impact

  • Predicted likelihood of individuals seeking medical care for illness given personal characteristics and health experiences

​​

Product Analytics & Consumer App

• Led product analytics for the Evidation consumer app, where 5+ million members connect wearables, get personalized health insights, and earn rewards for healthy behaviors

• Spearheaded the redesign of Evidation’s consumer app points program to achieve a 40% reduction in operational spend.

  • Created segmentation and forecasting models to accurately predict impacts before launch

  • Optimized behavioral incentives to encourage members to use app to its potential

  • Retained most valuable and active members after launching new program

• Built and maintained dashboards used company-wide to monitor consumer engagement, data ingest and product health, budget spend, A/B testing and campaign performance

• Designed and deployed A/B tests, new app features, content, and incentive programs directly to members to increase engagement, resurrect churned members, and promote healthy behaviors

Strategic Impact​

• Held weekly State of the Data meetings to brief company leadership on our technology and data assets and provide data-driven strategic guidance 

• Independently supported a year-long consumer research program of 100,000 Evidation app members including the delivery of 200+ customized reports over a 25 week period. Reduced time to delivery by ~75% by developing tools for automated report creation. 

• Authored and co-authored 7 peer-reviewed publications, helping to establish Evidation’s position as a leader in digital health research.

​​​​

Information Design & Data Storytelling

• Founded the Data Design initiative

• Created style guides, palettes, and best practices documentation for technical contributors

• Provided consulting for data visualization, data storytelling, and information design

• Prepared external-facing materials (slides, infographics, publication figures, technical documentation) for teams and departments across the organization

Partnerships with Industry and Government

• Owned final delivery of projects with $1M -$20M revenue 

• Partnered with teams at leading technology, pharmaceutical and government institutions, including Moderna, Roche, Genentech, Sanofi, AbbVie, and BARDA (US Dept. of HHS). 

• Guided collaborators through the remote clinical study lifecycle, to take their studies from their initial concept through study design, data collection, analysis, results delivery, and publication.

​

Collaboration and Communication

• Earned a reputation for building rapport, garnering trust, and delivering with excellence to both internal stakeholders and external collaborators

• Collaborated seamlessly across multidisciplinary teams, including engineering, executive, clinical, and regulatory stakeholders - became fluent in the vocabulary and conventions of disparate fields

• Presented findings to external stakeholders, contributing to published guidelines and academic literature.

• Developed reproducible workflows and documentation to ensure data integrity and facilitate knowledge transfer across teams
