Modern computing has greatly accelerated the collection of large amounts of data. Searching for important statistical patterns within this data is harder than simply finding a needle in a haystack. It is more akin to looking for a specific needle in a box of needles in a needle box factory.
My work focuses on developing statistical methodology to analyze data from the human microbiome and determine which microbial taxa are linked to common human health issues such as inflammatory bowel disease and obesity. I am interested in establishing methods that guard against common threats to non-reproducibility. Specifically, my work broadly focuses on methods that control the number of false positive taxa and methods that are explicitly robust to outliers within the data.
