Clinical Associate Professor of Biostatistics

Professional overview

Alex Dahlen, PhD joins GPH as Director of the new Collaborative Statistical Core in the Department of Biostatistics. The goal of the Core is to collaborate widely throughout the School, to bring robust statistical methods and thoughtful study design to public health research, and to train the next generation of data scientists and statisticians in team science and applied statistics. Dr. Dahlen has nearly 10 years of experience working in collaborative statistics, across a variety of settings in and out of academia.

In his previous role as senior statistician in the Quantitative Sciences Unit of the Department of Medicine at Stanford University, Dr. Dahlen collaborated with physicians and clinical researchers on all aspects of research, including acting as lead statistician on grant applications and statistical author on numerous published manuscripts. He devotes a large portion of his time to mentoring junior scientists: providing hands-on coding lessons; overseeing analysis; offering study design and methodology tutorials; and lecturing about healthy research practices. Dr. Dahlen received his PhD in the physics of bubbles from Princeton University in 2011.

Abstract
Abstract
COVID-19 manifests with respiratory, systemic, and gastrointestinal (GI) symptoms. SARS-CoV-2 RNA is detected in respiratory and fecal samples, and recent reports demonstrate viral replication in both the lung and intestinal tissue.2, 3, 4 Although much is known about early fecal RNA shedding, little is known about long-term shedding, especially in those with mild COVID-19. Furthermore, most reports of fecal RNA shedding do not correlate these findings with GI symptoms..
