About me
My name is John Muschelli (pronounced Moo-shell-e), and I am an Associate Research Professor in the Department of Biostatistics at the Johns Hopkins Bloomberg School of Public Health (JHSPH). I received my ScM in Biostatistics under the advising of Brian Caffo and my PhD under Ciprian Crainiceanu, both from JHSPH, and a BS in Biomathematics and Neuroscience from the University of Scranton.
I work on wearable and accelerometry data (step counts, sleep, physical activity in studies like NHANES and UK Biobank) and on processing and analyzing medical images, usually of the brain (more on my research). I write a lot of R software to make that easier, teach data science, and co-host the podcast The Corresponding Author.
My blog, A HopStat and a Jump Away, is updated much more often than this site.
