Katherine J Evans
Acting Division Director, Computational Sciences and Engineering Division
Katherine J. Evans is the Group Leader for the Computational Earth Sciences group and a member of the Earth Systems Modeling Group in the Climate Change Science Institute at ORNL. She develops high-resolution global Earth system models as a member of the DOE Accelerated Climate Modeling for Energy (ACME) project. She investigates global and regional model accuracy and climate variability as part of ACME and evaluates the model characterization of extreme events within global climate. Evans does research on developing and implementing scalable numerical algorithms to improve coupled model efficiency and accuracy for multi-scale configurations as part of the DOE BER SciDAC (Scientific Discovery through Advanced Computing) project, "Multiscale Methods for Accurate, Efficient, and Scale-Aware Models of the Earth System." As the ORNL site-PI and Validation and Verification task lead for the SciDAC project, "Predicting Ice Sheet and Climate Evolution at Extreme Scales (PISCEES)," she leads a team to develop advanced evaluation metrics and software for the Community Ice Sheet Model within the DOE Accelerated Climate Model for Energy (ACME) and the Community Earth System Model (CESM).
Evans earned her PhD in atmospheric science with an emphasis in math from the Georgia Institute of Technology in 2000. She joined ORNL in 2007 after a stint as a post-doctoral researcher and staff member at Los Alamos National Laboratory in the Decision Applications and Theoretical Division. She is a member of the American Meteorological Society, American Geophysical Union, and the Society of Industrial and Applied Mathematicians.
