Tim C. Johnson
INSITE Technical and Programmatic Lead

Tim C. Johnson is a computational scientist in subsurface geophysical imaging and interpretation related to complex environmental challenges and energy applications.

He is nationally and internationally recognized for his work in electrical resistivity tomography (ERT) as a characterization and monitoring technology. He pioneered the development of E4D-RT, a real-time, four-dimensional subsurface imaging software that allows scientists to “see” subsurface processes and solutions in real-time. Johnson and his team received a prestigious R&D 100 Award in 2016 for this tool.
