My Scientific Interests:
Climate variability from inter-annual to centennial time scales, the water and energy cycle in a changing world are my main interests in science. I pioneered research on global dimming and work on climate implications of natural and anthropogenic forcings as detected in observations and indicated in climate models. Taking measurements of aerosols and solar radiation and investigating climate effects on ecosystems are also part of my research interests. More recently I started applying my knowledge to solar energy and alternative energy usage.
