haitemaHendrik M. Haitjema, Ph.D.
Indiana University

Hendrik M. Haitjema, Ph.D.,  joined Indiana University in 1984 where he served as a professor at the School of Public and Environmental Affairs until August 2012.  He taught, among other subjects, groundwater flow modeling and applied mathematics.

Haitjema has a specialization in groundwater hydrology.  His research interests include both the development and application of mathematical models for regional groundwater flow systems, three-dimensional groundwater flow embedded in two-dimensional flow models (Dupuit-Forchheimer models), fresh and salt water interface flow, transit time distributions in watersheds, and the conjunctive modeling of surface water and groundwater flow.  The emphasis in his research is on the application of analytic functions in modeling groundwater flow, the Analytic Element Method (AEM).

He published the analytic element model “GFLOW” in 1994 and the book Analytic Element Modeling of Groundwater Flow in 1995.  He also published on the performance of the finite difference code MODFLOW and developed a hybrid GFLOW-MODFLOW modeling approach.

Haitjema received his master’s degree in civil engineering from the Technical University of Delft, The Netherlands in 1976 and his Ph.D. in civil engineering from the University of Minnesota in 1982.  He regularly serves as a consultant to professionals and the public.

Executive Editors

Thomas M. Missimer, Ph.D.
Florida Gulf Coast University


Thomas M. Missimer, Ph.D., is a visiting professor of environmental science and engineering at the Florida Golf Coast University and president of Missimer Inc., a groundwater consulting firm.

He has 40 years of experience in hydrogeology, beginning his career as a hydrologist with the U.S. Geological Survey.  He spent a year at the Rosenstiel School of Marine and Atmospheric Science, University of Miami, and then worked as a consultant for the next 34 years.  He founded three consulting firms and merged or sold each company.  He has been in academia for the past three years.

His current research includes development of wastewater aquifer storage and recovery (ASR) projects using wadi aquifers, the use of natural filtration for water treatment, development of strategic storage ASR projects to mitigate global climate change and for emergency water use, subsurface intakes systems for seawater desalination facilities, the development of geothermal energy resources in the Middle East region using hot-dry rock heat harvesting and combining it with seawater desalination, development of new empirical methods for estimating hydraulic conductivity from grains size distribution, and the effects of dust deposition on soil hydraulic properties.

He is the author of eight books.  He has a master’s degree in geology from Florida State University and a Ph.D. in marine geology and geophysics from the University of Miami.


Robert Schincariol
University of Western Ontario

schincariol-webRobert A. Schincariol, Ph.D., is a professor of hydrogeology, cross-appointed to the departments of earth sciences and civil and environmental engineering at the University of Western Ontario.

Schincariol previously served as editor and discussions editor for Groundwater® (2011-2013) and associate editor for the Canadian Geotechnical Journal (2002-2007).

His research interests are in physical hydrogeology with a focus on heat transport, low-temperature geothermal energy, permafrost hydrogeology, and variable-density flow.  Typically, projects involve the coupling of laboratory, field, and numerical modeling studies.  He teaches courses in watershed hydrology, physical and chemical hydrogeology, and groundwater flow modeling.

He received his master’s of science degree in geology from the University of Alberta and a Ph.D. in geological sciences from The Ohio State University.  He regularly serves as a consultant to government and industry.


Yu-Feng Forrest Lin, Ph.D.
University of Illinois at Urbana-Champaign

linYu-Feng Forrest Lin, Ph.D. is a hydrogeologist at the Illinois State Geological Survey, Prairie Research Institute, University of Illinois at Urbana-Champaign and previously served as Associate Editor (2011-2016) and Technology Editor (2014-2016) for Groundwater®. 

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.
