About Me
I’m Alex, a PhD student in the Statistical Science department at Duke University, supervised by David Dunson and Amy Herring. Previously, I obtained my undergraduate and master’s degrees from McGill University.
I work on statistical methods for complex data with a strong mathematical foundation. Recently, I have focused on decision theory, Bayesian nonparametrics, and categorical data analysis. I am also an active member of the Sepsis Characterization in Kilimanjaro (SICK) team, a research group focused on identifying subtypes of sepsis in sub-Saharan Africa.
Outside of statistics, I like running, the NYT crossword, playing guitar, and watching the Premier League.
