Technical Staff Member, Computational Earth Sciences Group at Oak Ridge National Laboratory . Research interests: fully implicit solution methods for climate modeling, high resolution climate model development, ice sheet model development.


Current projects:

High Resolution Atmospheric Modeling
LDRD: Prediction of the Earth System after major volcanoes
Ice Sheet Modeling
SEACISM Project which is part of a new initiative from DOE's office of science, ISICLES.
Climate Model Development
Modeling the Earth System

Recently I have been implementing a fully implicit solver capability within a global atmospheric model, CAM-HOMME using Trilinos . Right now, this option is only applied to the shallow water test cases. HOMME is a spectral element discretization dycore option in the community atmosphere model (CAM), which is part of the CCSM. Among other things, this capability will provide a basis for parameter continuation calculations. There is still lots of work to do, so stay tuned.

My background explains my current interests; I got a B.S. in Physics from Haverford College performing fracture mechanics experiments under Jerry Gollub. I have a Ph.D. from Georgia Tech in Atmospheric Science performing diagnostics of persistent large scale weather systems using potential vorticity under Rob Black, and I did a postdoc at Los Alamos National Laboratory in the Theoretical Division under Dana Knoll developing fully implicit methods for convection models with phase transition.

There is no relation between me and the Kate Evans on the other side of the pond who has written a cartoon book about climate. Isn't it neat there are two 'Kate Evans' with an interest in the complex Earth system?
