Biography
After earning my Bachelors of Science degree in Biostatistics from Emmanuel College in 2019, I earned my Masters of Science degree in Applied Statistics and Research Methods from the University of Northern Colorado in 2020. During my time as a student, I presented and completed many research works, including multiple presentations at the Biophysical Society Meeting and a Master's Thesis.
Within the Yale Center for Analytical Sciences, I now work as a Biostatistician to support both internal analytical projects, as well as clinical trial studies that often involve investigators outside of Yale.
I conduct analyses implementing statistics, biostatistics, and epidemiology on health research projects. I also provide consultation on the research design, data management, statistical programming, analysis, and reporting portions of each assignment.
A large portion of my work results in publications in peer-reviewed journals or presentations at conferences. Examples of work published in scientific journals include Blood, Menopause, Journal of Vascular Surgery, and more.
