Short Biography:
Dr. Juarez-Colunga is an Associate Professor in the Department of Biostatistics and Informatics at Colorado School of Public Health, University of Colorado Anschutz Medical Campus. She is originally from Mexico and she received her PhD in Statistics from Simon Fraser University in Canada. Dr. Juarez-Colunga has been a collaborative biostatistician since 2012 at the University of Colorado Anschutz Medical Campus. She is currently the president of the Western North American Region (WNAR) of IBS and her research areas of interest are survival analysis, recurrent events, longitudinal data, and joint models.


Modeling event time data poses challenges in several situations; for instance, when there are several events that may repeat over time or when multiple outcomes of interest are recorded. Extensions of time-to-event analyses are needed in many areas of the sciences, social sciences, medicine and elsewhere. In this talk I will provide a brief introduction to a few extensions of time-to-event analyses, and will talk about applications of such extensions in the context of health care outcomes. An example that will be covered is the modeling of dynamic prediction of time to development of biomarker of kidney rejection in patients with kidney transplant, based on variability of a longitudinal immunosuppressant.
