Sherilyn Williams-Stroud is an American Research Scientist and Structural Geologist, at the Illinois State Geological Survey/ University of Illinois Urbana-Champaign. Sherilyn is also president and CEO of her own company Confractus Inc. and is an expert on the topics of structural and fracture analysis and modelling for oil, gas, and geothermal production specializing in microseismic data interpretation and induced seismicity.

Education
She received her BA in Ohio from Oberlin College (1974-1981), and her MA and PHD from John Hopkins University (1983-1988) in Baltimore, Maryland.

Work
Williams-Stroud has published and contributed to over 30 publications and has over 25 years of work experience in government and industry. She previously taught Industry short courses in structural modeling, fracture modeling and microseismic mapping; and has also been employed at multiple accredited Universities like the University of Houston, California state University (Los Angeles and Northridge), and a full time faculty member at Whittier College. As an active member of numerous professional organizations and 4 year member of the NASEM committee on Seismology and Geodynamics, she continues to pursue the work of integrating scientific knowledge related to induced and natural earthquakes with translating that knowledge for the general public.

Another important aspect of Williams-Stroud's work is her position as the president and CEO of Confractus Inc. which provides technical support, training, and tech transfer to client sin the oil and gas industry. The company includes numerous areas of expertise including geological analysis, interpretation and remodeling related to fracturing and fractured rock. The type of projects that their team works on includes structural restoration, fault and fracture prediction and analysis, microseismic data interpretation, and fractured reservoir characterization.
