Causal Inference, Bayesian, & Machine Learning Expert | Proven Track Record in Research & Production Modeling

Profile Summary

I hold a PhD in Biostatistics from the University of Minnesota and have over a decade of experience in statistical modeling, causal inference, and machine learning across academic, public health, and industry settings. My expertise lies in the development and application of advanced statistical and machine learning methodologies, including Bayesian modeling, simulation-based inference, and doubly robust estimation, to real-world problems in healthcare, economics, and decision science. As an Assistant Professor at The Ohio State University and the University of Nevada, Reno, I led NIH- and World Bank-funded research projects focused on health outcomes, methodological innovation, and interdisciplinary collaboration. My work has resulted in over 20 peer-reviewed publications in journals such as Biometrics, Statistical Methods in Medical Research, and Nicotine and Tobacco Research. In the private sector, I’ve served as a Senior Data Scientist at Swish Analytics and DraftKings, where I built, deployed, and maintained production-level models used to simulate sports outcomes and price betting markets in real time. These roles required deep integration of causal modeling, experimentation frameworks, and real-time data pipelines in high-stakes environments. I’m also the developer of two open-source methodologies—SSCE (Spike and Slab Causal Estimator) and GLiDeR (Group Lasso Doubly Robust Estimator)—used by researchers worldwide for confounder selection and causal effect estimation in observational studies. Key Skills & Tools: Causal inference, Bayesian modeling, longitudinal data analysis, A/B testing Machine learning (supervised/unsupervised), simulation modeling Python, R, SQL, MATLAB, SAS, Stan, C++ AWS, Kubernetes, Docker, GitHub, CI/CD Academic writing, peer review, and grant-funded research Whether you need support with study design, statistical analysis, model development, or research publication, I bring both methodological rigor and applied experience to deliver high-quality, actionable insights.
