Professor Derek Elsworth is G. Albert Shoemaker Chair and Professor of Energy and Mineral Engineering and Geosciences at Pennsylvania State University in USA. His research interests are in the areas of computational mechanics, geomechanics and geophysics with application to induced seismicity and the related evolution in the mechanical and transport characteristics of fractured rocks, with application to geothermal energy, the deep geological sequestration of radioactive wastes and of CO2, and the storage and production of hydrogen and unconventional hydrocarbons including coal-gas, tight-gas-shales and hydrates, and instability and eruption dynamics of volcanoes.
