Ty Ferre, Ph.D.
University of Arizona
tyferre@gmail.com

Ty Ferre, Ph.D., is a distinguished professor in the department of hydrology and atmospheric sciences at the University of Arizona.

He teaches courses in subsurface hydrology, hydrogeologic field methods, groundwater modeling, and decision-making. His research interests include improved extraction of information from indirect (geophysical) observations for hydrogeologic applications, the design of monitoring networks, and the development of groundwater models to improve water-resources decision-making.

He was the 2016 Darcy Lecturer, delivering a talk entitled “Seeing Things Differently: Rethinking the Relationships Between Data, Models, and Decision-Making.”

He received his B.Eng. in geophysical engineering from the Colorado School of Mines and his Ph.D. in Earth sciences from the University of Waterloo.

His current research interests include groundwater and surface water interactions, hydrogeological effects on geothermal exchange, environmental impacts associated with geologic carbon sequestration, and numerical modeling for groundwater flow systems.

He is a licensed professional geoscientist and certified geographic information systems professional. He is also a clinical professor in the department of civil and environmental engineering and a research professor in the department of natural resources and environmental sciences at the University of Illinois at Urbana-Champaign.

Lin received his B.S. in water resources and environmental engineering from Tamkang University in Taiwan, his M.S. in civil and environmental engineering from the University of Connecticut, and his Ph.D. in geological engineering from the University of Wisconsin-Madison.

Tim Grundl, Ph.D.
University of Wisconsin-Milwaukee
grundl@uwm.edu

Tim Grundl, Ph.D., was a professor for more than 35 years in the department of geosciences and was associate dean at the School of Freshwater Sciences at the University of Wisconsin - Milwaukee. His teaching included courses in aqueous geochemistry, contaminant fate and transport, and hydrogeologic field methods.

His research interests include the chemical dynamics of groundwater systems with particular interest in contaminant degradation, the use of isotopic and noble gas tracers to deduce aquifer recharge history. and the development of in-situ sensing devices for the detection of heavy metals and PAHs.

Grundl is a Fellow of the Geological Society of America. He received his B.S. in geology from the University of Delaware, his M.S. in geology from Northern Illinois University, and his Ph.D. in geochemistry from the Colorado School of Mines.
