Dr. Modrick Hansen became HRC’s Chief Operating Officer in October 2023. As such, she leads the team of HRC scientists, engineers and developers on projects leading to the implementation of HRC-developed operational systems, including the Flash Flood Guidance Systems with Global Coverage (FFGS/WGC) program, a partnership with USAID, US NOAA, and WMO. Dr. Modrick Hansen brings to the position her experience in scientific research, hydrologic modeling, NWP modeling, data analysis, and system development for programs such as FFGS, the California Integrated Forecast and Reservoir Management (INFORM,) and others over 25+ years at HRC, and the U.S. Army Corps of Engineers prior to HRC.

Dr. Modrick Hansen primary interests have been in hydrologic modeling, characterization of the impacts of uncertainty in hydrologic simulations and forecasts (particular on small spatial scales), climate change impacts on hydrologic processes and local/regional climatologies, and precipitation modeling and forecast uncertainty. Her interests also includes implementing effective training and education programs as part of HRC’s operational system implementations. She has been highly involved in HRC’s training activities as co-coordinator and instructor in various trainings.

Dr. Modrick Hansen received her B.S.E. (1991) and M.S. (1993) degrees in Civil Engineering from the University of Iowa, and her Ph.D. in 2011 from the Scripps Institute of Oceanography at the University of California San Diego. Her doctoral research focused on climatic variability of small-scale flooding and potential changes to flash flood occurrence in Southern California under future climate.
