Summary
My methodological research interests include statistical machine learning, data mining, and nonparametric methods for complex, high-dimensional data. I currently am working on developing novel methods to identify and validate clusters in high-dimensional, low-sample size data sets. My applied research interests include chronic pain conditions, specifically temporomandibular disorders and canine osteoarthritis.
