The LEAD Mission

1. To develop a unique and innovative climate science research and education program with a national and international reputation.
2. To carry out climate research that balances basic theoretical and modeling work with impacts assessment and societal applications.
3. To help reduce vulnerability to and possibly take advantage of the impacts of climatic variability and climatic change on local, regional, and global scales.

LEAD receives tremendous federal support from the EPA, KAUST, NASA, NOAA and NSF as well as support from the Geology Foundation.

What Dr. Yang Has Accomplished

What I have done at UT-Austin in the past eight years is to build the LEAD program in the Department of Geological Sciences that quantitatively addresses the impacts of climate variability and climate change on environmental issues of societal importance, such as the conditions of freshwater resources, ecosystems, and air quality. My publications include more than 80 peer-reviewed articles (well over 40 in the past 8 years at UT-Austin), in addition to about 80 conference proceedings papers, research reports and presentations abstracts, with a total citation of 2500 and a current “Hirsch Index” of 29. I have won just over $4.5M total as the PI in external funding. My graduate students have received prestigious federal fellowships from the National Science Foundation, NASA, NOAA, Department of Homeland Security, and the AGU Hydrology Section’s Horton Research Grant. I have received the Joseph C. Walter Jr. Excellence Award, the most prestigious award at the Jackson School of Geosciences.

At UT-Austin, I have collaborated with Jackson School of Geosciences colleagues in the Department of Geological Sciences (DGS), the Bureau of Economic Geology (BEG) and the Institute for Geophysics (UTIG), as well with scientists in other academic units and institutions. These include, but are not limited to:

• Hydrogeology and water resources (Bridget Scanlon at BEG and Jack Sharp at DGS);
• Speleothem and paeloclimate (Jay Banner at DGS, Charles Jackson at UTIG, and MaryLynn Musgrove at DGS and USGS);
• Gravity Recovery and Climate Experiment (GRACE) satellite hydrology and Geophysics (Clark Wilson at DGS and Jianli Chen at the Center for Space Research);
• Optimization and calibration (Mrinal Sen and Paul Stoffa at UTIG);
• Urban development (Barbara Parmenter at the School of Architecture);
• Biogenic emissions, atmospheric pollution and air quality (David Allen at the Dept of Chemical Engineering and Keith Hutchison at the Center for Space Research);
• River flow and flood inundation modeling (David Maidment, Ben Hodges  at the Dept of Civil, Architectural and Environmental Engineering);
• Biosphere–atmosphere interactions (Camille Parmesan, Tim Keitt, Marcy Litvak, and Christine Hawkes in the Section of Integrative Biology);
• Riverine nutrient export and coastal environmental studies (Paul Montagna, Jim McClelland, Marine Science Institute); and
• Decision making under uncertainties (Eric Bickel, Mechanical Engineering)

In teaching, I have developed three new courses at UT-Austin, an introductive undergraduate course “Climate: Past, Present and Future” to a big class of 120 non-majors, and courses “Hydroclimatology” and “Physical Climatology” to graduate students. In addition, I have taught two undergraduate courses “Living with a Planet” and “Earth, Wind and Fire” to 250 to 300 non-science major students. I lectured “climate change” as part of “Modern Geological Sciences” to incoming graduate students who do not have a solid background in geology. I received in 2004 a Teaching Excellence Award from the UT-Austin College of Natural Sciences.

My research program has not only attracted top students to come to my LEAD program to pursue their graduate degrees, but also attracted acclaimed climatologists and hydrometeorologists and top researchers to visit (e.g., Roger Pielke Sr. of Univ of Colorado, Robert E. Dickinson of Georgia Tech, Soroosh Sorooshian of UC Irvine, Alan Robock of Rutgers University, Roy Rasmussen of NCAR, Ken Mitchell of NCEP, Fei Chen of NCAR, and Paul Dirmeyer of COLA). My program has benefitted from the recent arrival of Drs. Robert E. Dickinson, Rong Fu, Kerry Cook and several other climate scientists who joined, as faculty members, the Department of Geological Sciences at the Jackson School of Geosciences in 2008. Together, we have emerged as a strong climate system science program.
