Course Instructors

Our professional instructors are experts in the use of environmental software for practical hydrogeologic analysis and modeling. Waterloo Hydrogeologic develops environmental software with a focus on groundwater and trains users in applying that software to deal with real world issues.

Kristian Doerken
MASc, PE (Virginia) Instructor

Kristian Doerken is the Product Manager for all software products at Waterloo Hydrogeologic. Before leading the development of our products, he worked as an environmental engineering consultant and has over a decade of experience providing practical water resource solutions to municipal, federal, and industrial clients across North America, including subsurface investigations, groundwater site characterization and modeling, remediation, and restoration; flood evaluations; water supply planning; watershed management and modeling; and stormwater management. He has taught a large number of training courses on groundwater modeling and hydrogeology in North America.

Nick Lyle
MSc, Instructor

Nick Lyle is the lead trainer at Waterloo Hydrogeologic. He earned an M.Sc. in Earth Science (Water) from the University of Waterloo and a B.S. in Earth Science from the University of Oregon. His graduate research focused on the statistical evaluation of numerical hydrological models and the physical and chemical hydrogeology of oxidizing mine tailings cover systems.

Nilson Guiguer

Dr. Guiguer is a specialist in the numerical modelling of groundwater. He has helped in the design of several numerical modeling packages used with his clients. He has an M.Sc. in Water Resources from the University of Sao Paulo, Brazil, and Ph.D. in Hydrogeology from the University of Waterloo, Canada. Dr. Guiguer has acted as a consultant in numerous significant projects involving mine dewatering, water resources, environmental impacts, and remediation. A recognized expert, he is a recipient of the NGWA’s John Helm Award for significant contribution to the groundwater science and has taught more than 100 professional courses around the world.

András Jakab

András Jakab has been in the environmental remediation business since 1992, when he started his professional activity within Hungary’s largest environmental remediation project in Jászberény – Electrolux remediation project. He has since participated as a groundwater modeler and risk assessor in several projects in Hungary and Romania for clients representing industries such as pharmaceutical (EGIS, etc.), automotive (Daewoo, etc.), engine manufacturing (CG Electric, etc.), white products (Electrolux, Dometic, etc.), or municipalities and agricultural clients. Andras started his own environmental consultancy in 1997 and is the managing director. He has attended several international modeling training courses and is an instructor for Waterloo Hydrogeologic.

Rafael Albuquerque

Rafael Albuquerque graduated with an undergraduate degree in Geology from Acadia University and with a master’s degree in geology focused on hydrogeochemistry from Simon Fraser University, Canada. He has more than 10 years of experience in hydrogeology and hydrogeochemistry projects, having worked in projects related to mining, regional aquifers, natural and anthropic occurrence of metals and other solutes in groundwater, and the use of hydrogeochemical and isotopic parameters in hydrogeological studies. He has solid experience in conceptual and numerical modeling of flow and transport. He received an award from the Geological Society of America for the quality and relevance of his master’s research, related to the mobilization of metals in groundwater. He is a member of the Water Services and Technologies consulting team and regularly teaches courses and webinars on numerical modeling, hydrogeochemical data analysis, and interpretation of pumping tests.

Ines Guimarães

Ines Guimarães is a chemical engineer with a degree in Sanitary and Environmental Engineering. Currently, Ines is part of the Water Services and Technologies Data Management team implementing and managing environmental databases for corporate clients using Hydro GeoAnalyst. She has led numerous focused and applied training sessions for client teams on the practical usage of Hydro GeoAnalyst to manage environmental data.

Lara Lange

Lara Lange is a geologist with a Master’s degree in Exploratory Geology from the Paraná Federal University with university extension at the California Institute of Technology (Caltech) and a Riad Salamuni award for academic performance. She specializes in chemostratigraphy, geochemistry, geotectonic and geological mapping and has experience performing and interpreting laboratory analyses such as XRD, XRF, conventional and grouped stable isotopes (Clumped Isotope Thermometry), scanning electron microscope (SEM-EDS) and in the preparation and description of thin sections. She is currently in the hydrogeology and geochemistry groups Water Services and Technologies and is responsible for the interpretation of geochemical, hydrogeochemical and mineralogical data for geochemical modeling, as well as working in field projects to collect flow and level monitoring data, piezometer construction and aquifer tests. Lara has led numerous courses, seminars, and workshops on applied geochemistry, AquaChem, and Hydro GeoAnalyst.

Mauro Prado

Mauro is a geologist with an MSc in environmental sciences and specialized in hydrogeology, having worked in numerous consulting projects for the mining, beverage, and oil & gas industries, as well as water supply assessments for the public sector. In his 25 years of experience, Mauro has worked on the prospecting and management of groundwater resources, numerous mine hydrogeology projects, from field investigations to numerical modeling, as well as projects involving hydrochemistry, hydrology, environmental site assessments and data management. Mauro has taught numerous training courses on numerical modeling and aquifer testing, using Visual MODFLOW Flex and AquiferTest.

Christian Preis

Christian Preis is an Environmental and Sanitary Engineer with a M.Sc. in Hydrology. Christian has worked in several consulting projects involving water resources. Currently, Christian is the leader of the Data Management team at Water Services and Technologies, where he has worked to implement Hydro GeoAnalyst as a data management solution at numerous companies in the mining and water resources sectors. Christian has also led training sessions of Hydro GeoAnalyst for companies based in Brazil and internationally.
