Jonathan Thomle is a staff scientist that supports various PNNL projects by coordinating and leading lab- and field-scale tasks that require expertise in subsurface monitoring, environmental chemistry, and soil physics. Since he started at PNNL in 2011, he has been very versatile in providing valuable support for geophysical investigation and monitoring, subsurface modeling, aquifer sampling and analysis, subsurface gas sampling, remediation technology development, optical gas imaging, and cementitious material design. He received his M.S. in Civil and Environmental Engineering from WSU in 2010 where he researched cement chemistry and carbon sequestration. However, at WSU his main focus was on water treatment.
