Oveview: I have 24 years of U.S. and international experience leading and participating on teams that characterize, monitor, and model the ecological, geophysical, and water-resource response to natural and anthropogenic stresses. Because of limited information and nonuniqueness in these systems, I personally develop and apply methods to better conceptualize, parameterize, and calibrate models. I also investigate and quantify the associated model and prediction uncertainty in analytical and numerical models. In addition to collaborative problem solving, I enjoy writing technical articles, teaching university courses, providing workshops, and mentoring students.    Curriculum Vitae
