What I'm looking for

I seek data science roles where I can apply rigorous statistical methods, lead small teams, and translate analyses into actionable decisions within collaborative, compliance-aware environments.

I am a mid-level data scientist and statistician with over a decade applying advanced statistical methods, machine learning, and information theory across healthcare, transportation, AI, and academic research. I translate complex analyses into clear, actionable insights for technical and non-technical stakeholders.

I have led small teams and served as lead statistician on NIH-funded projects, integrating multi-source medical datasets and navigating government research regulations. My work for public-sector clients included transportation optimization that informed leadership decisions and cost-saving measures.

I bring deep experience in R, Python, SQL, entropy-based feature selection, predictive modeling, and statistical consulting, and I am open to applying data science skills across industries where rigorous, data-first decision-making is valued.
