Research Interest & Projects

My research interests are focused on methods to study the mechanisms and associations that underlie processes which unfold through time. Such methods include both aspects of the design of experiments and of the analysis of data from experiments and surveys. I am particularly interested in methods that help to disentangle complex sequences of information related to the natural history of specific disease processes and their treatment.
My recent collaborative work includes: (1) comparison of treatment modalities for patients with end stage renal disease, and (2) evaluation of variability in hospital admission rates among communities.
