Madeline McCarren, PhD, MPH, is a biostatistician in the Department of Veterans Affairs.

She earned a BS in Chemistry in 1978, a PhD in pharmacology in 1982, and an MPH in epidemiology in 1992. McCarren has worked with both primary and secondary data. She has designed, conducted, analyzed, and published studies based on both experimental and observational designs. Because of her diverse training and experience, her niche is to provide a bridge between subject matter experts and statisticians and design effective and efficient studies. She can often see opportunities and potential pitfalls that those separate groups miss.
