Freelance Biostatistician & Clinical Trialist | R | 10+ Years Experience

Profile Summary

I am a PhD-trained biostatistician with over 10 years of experience supporting clinical trials, observational studies, and translational research. I work closely with investigators and industry partners on study design, statistical analysis plans, and interpretation of complex biomedical data. My expertise includes longitudinal and repeated-measures modeling, generalized estimating equations, survival analysis, and regression-based approaches, with an emphasis on methods that align with the scientific question and study design. I primarily work in R, with experience in SAS. I offer biostatistical consulting for clinical research, including power calculations, data analysis, manuscript and grant support, and independent statistical review. I value clarity, rigor, and practical guidance, and I aim to help teams produce results that are both methodologically sound and clearly communicated.
