Tristan's primary area of statistical research is in methodology for the design and analysis of biomarker discovery and validation studies. He has presented reserach at several conferences including the EDRN, Joint Statistical Meetings, UCLA Department of Medicine Research Day, and the SCASA Applied Statistics Workshop. His statistical interests include statistical education, running interrupted time series analyses, survival analyses, and CART models (classification and regression trees). His primary clinical applications have come from the departments/divisions of Anesthesiology, Dentistry, Oncology (primarily in lung, prostate, gastric), Pediatrics, Urology, and Cardiology.
