Gail E. Potter, PhD

Mathematical Statistician 

Biostatistics Research Branch

National Institute for Allergy and Infectious Diseases

National Institutes of Health

I am the Deputy Section Chief of the Clinical Trials Research Section of NIAID's Biostatistics Research Branch.  Prior to joining NIH, I was a principal biostatistician at the Emmes Company for 5 years and an Assistant Professor of Statistics at California Polytechnic State University for three years.  I completed my PhD in statistics at the University of Washington and a postdoctoral research fellowship at the Fred Hutch in Seattle. 

My research involves development and application of statistical methodology to improve global health.  I have provided statistical leadership to more than 20 clinical trials and have developed statistical models for social contact networks to better understand epidemic transmission in a variety of countries and contexts.

I am a returned Peace Corps Volunteer (Guinea, Nepal).  My experience in Peace Corps continues to inform my passionate perspective on social justice.

Web Applications created with Shiny and R

Maximum Likelihood Estimation.  This app illustrates the concept of maximum likelihood estimation through the example of estimating a binomial proportion.  

Robustness of ANOVA.   This app allows the user to explore robustness of ANOVA to violation of the constant variance assumption and derive a rule of thumb for practitioners of statistics.

Sampling distributions.  This app uses simulation to illustrate the concept of sampling distributions.  Various population shapes and statistics (min, max, mean, median, quartiles, etc.) can be selected by the user. 

These apps are part of the Cal Poly Shiny Series.

        Multiple Regression Visualization, in which various regression surfaces are visualized in three dimensions; and 

        Probability Distribution Viewer, which displays various probability distributions, p-values, and quantiles.
