Data scientist & biostatistician

My work spans clinical trials, real-world evidence, claims, observational studies, and biomedical data. I lead analysis projects end to end: defining the question, carrying out the statistical work, building supporting software, and communicating the results.

What I do

Healthcare data analysis

Most of my work involves leading analysis projects end to end: deciding what questions to ask, choosing an appropriate approach, carrying out the analysis, and building tools that help teams understand the results.

01

Healthcare data

Clinical trials, real-world evidence, claims, observational cohorts, patient-reported outcomes, and biomarker data.

Data science and statistics

02

Statistics and machine learning

Survival and longitudinal analyses, causal inference, mixed-effects models, simulation, predictive modeling, and subgroup analyses.

Methods and experience

03

Analytical software

Reproducible workflows, R packages, Shiny applications, dashboards, testing, and deployment using R, Python, and related tools.

Background

Experience across healthcare data

My experience spans biopharma, contract research, and real-world data. Across these settings, I have worked cross-functionally with clinical, translational, medical affairs, biostatistics, data science, data engineering, IT, and operational teams.

In senior roles, I have led technical work, helped set standards for code quality and validation, and mentored colleagues. I care about clear communication, reproducible analysis, and tools that other people can maintain.
