Mari Tye, ECEP® Project Lead
Mari Tye is a Civil Engineer, with 10 years experience in flood mitigation and sustainable drainage, highways design, ports and harbor design, construction supervision, and master planning for large-scale developments. She is currently a researcher at the National Center for Atmospheric Research specializing in the statistics of extreme and high impact weather and climate events. Before studying for her PhD related to changes in extreme rainfall over the UK at Newcastle University, she held positions at CH2M and AECOM, and briefly volunteered in Uganda as a water resource engineer. Mari holds a Master’s Degree in Civil Engineering and French from Nottingham University and has corporate membership in the UK’s Institution of Civil Engineers (PE Equivalent) and a PhD in Statistical Climatology.

Cindy Bruyère, ECEP Systems Lead
Cindy Bruyère leads the NCAR-based systems development effort for the Engineering for Climate Extremes. She plays a key role in the development of the Global Risk, Resilience, and Impacts Toolbox® (GRRIT®). In her role, Cindy directs efforts to incorporate tools as they are developed into GRRIT, spearheads related database construction, maintenance, and management, and is responsible for climate downscaling efforts conduct by the group. Cindy has an MSc in Dynamical Modeling and a PhD in Environmental Management. She started her career at the South African Weather Service, where she rose to Assistant Director of research programs, and Project Manager for operational systems. Her crrent research activities include understanding and predicting the impact of climate variability and change; dynamical model development; creating useful climate decision-making tools; and the development of statistical downscaling techniques.

James Done, ECEP Science Lead
James Done is a Willis Research Fellow and science lead for the National Center for Atmospheric Research’s Engineering for Climate Extremes Partnership, Boulder Colorado. He is engaged in an active research program on future changes in extreme weather and societal impacts. His specific research interests include; understanding the physical processes leading to  high-impact weather and climate events, predictability limits and variability of high-impact weather events across a range of temporal and spatial scales, and drivers of societal impacts, incorporating weather, climate, exposure, vulnerability and human behavioral factors. James obtained his BS and PhD in Atmospheric Science/Meteorology from Reading University.

Greg Holland, ECEP Director
Greg Holland, ECEP's Director, also leads the Regional Climate Prediction Program at the National Center for Atmospheric Research (NCAR). He was previously Director of NCAR’s Earth System Laboratory. His current research focuses on regional climate prediction, hurricanes and applications of extreme value theory. His career in tropical meteorology includes forecasting, teaching, research, and community service, including service on a number of committees and review boards for NOAA, the National Academies and NASA, and chairing the Tropical Meteorological Program of WMO. His publications include major contributions to six textbooks and forecast manuals, and more than 100 peer-reviewed research papers. Greg received his bachelors in Mathematics from the University of New South Wales, Australia, and an MS and PhD in Atmospheric Science from Colorado State University.
