I am a micrometeorologist with interests in wind energy and land surface-atmosphere flux exchange. My experience in wind energy research ranges from deploying lidar and in situ instrumentation to evaluating turbine power performance response. Currently I work on DOE funded projects in wind resource characterization. These include measurement studies to better understand flow over complex terrain, flow within wind farms, and plant-scale plant response to atmospheric conditions. I am also the PI of the Diablo Grassland AmeriFlux tower at Site 300 (Altamont, California) and co-PI of the Wind River Old-Growth Forest AmeriFlux tower in Washington State. At these sites we are measuring net carbon, water and energy exchange between natural ecosystems and the atmosphere. These measurements quantify whether these systems are a net carbon sink or source to the atmosphere.
