What I'm looking for

I seek a role that allows me to leverage data science for impactful decision-making and process optimization.

I am a data scientist with a Ph.D. in Biostatistics and over eight years of experience applying machine learning, statistical modeling, and data engineering to drive evidence-based decisions across education, health, and public policy.

My work has led to the automation of large-scale data pipelines (e.g., web scraping from Google Flights using Python), the development of predictive models (AUC > 0.80) to identify financial risk, and the creation of dashboards for 40+ institutions using Power BI. I have also designed complex sampling strategies and implemented A/B testing to evaluate educational interventions.

I am proficient in Python, R, SQL, Power BI, and AWS, and have published 15+ peer-reviewed papers. I’m passionate about transforming complex data into actionable insights and enjoy working on projects that have a measurable impact on people and organizations.

I’m currently looking to collaborate on impactful data science projects that require a blend of statistical expertise, machine learning, and scalable data solutions.
