Cross-USA lecture Tour 2022-2023

Timothy D Stark

Timothy D. Stark is a Professor of Civil and Environmental Engineering at the University of Illinois at Urbana-Champaign with an expertise in Geotechnical Engineering. Dr. Stark has been conducting interdisciplinary research and teaching on the static and seismic stability of natural and manmade slopes, such as dams, levees, floodwalls, embankments, and waste containment facilities, geosynthetics and geomembranes, soil liquefied strength, and railroad geotechnics.

Dr. Stark has been involved in a number of projects on these topics, which has facilitated the transfer of his research results to practice. He is currently researching two and three-dimensional slope stability, soil shear strengths, heating events in waste containment facilities, and drilled shaft integrity testing. Dr. Stark has received a number of awards for his research, teaching, and service activities including: 2022 T.H. Wu Lecture at The Ohio State University; 2019 George H. Norman Medal from the American Society of Civil Engineers (ASCE); Best Paper in Geosynthetics International Journal, 2016; Thomas A. Middlebrooks Award, ASCE, 2013 and 1998; Associate Editor Award, Journal of Geotechnical and Geoenvironmental Engineering, ASCE, 2012; R.M. Quigley Award from the Canadian Geotechnical Society, 2003, Walter L. Huber Research Prize, ASCE, 1999, and Arthur Casagrande Professional Development Award, ASCE, 1992.
