Biostatistics Sc.M. – Johns Hopkins Bloomberg School of Public Health
I’m a biostatistics master’s student at Johns Hopkins Bloomberg School of Public Health, graduating in May 2027. I hold a B.S. in Statistics from the University of Georgia.
At Johns Hopkins Medicine, I work on three cystic fibrosis studies, developing R pipelines to automate study reports and performing quality control and assurance on longitudinal patient health data. I’m also a graduate research assistant studying cognitive aging in older adults using data from the National Health and Aging Trends Study. This academic year, I’m serving as a teaching assistant for four courses in the Department of Biostatistics.
Before Hopkins, I conducted research at the University of Georgia, UC Irvine, and Columbia University on stroke outcomes, Alzheimer’s disease in individuals with Down syndrome, and Medicare costs associated with lung cancer, respectively. I work primarily in R, Python, SAS, and SQL.
