Linda M. Bonnell

President/Scientific Advisor 

Linda Bonnell is deeply involved in Geocosm’s geoscience research efforts and leads many of the company’s reservoir quality prediction and risk assessment studies. She has been instrumental in the development of Geocosm’s Touchstone system for reservoir quality assessment and prediction as well as Geologica’s Exemplar® diagenetic model. She also has extensive basin modeling experience.

In Linda’s AAPG Distinguished Lecturer tour in 2003 and 2004 she discussed the state-of-the-art in reservoir quality prediction technology as well as research on the interaction of quartz cementation and fracturing that is being done in collaboration between Geocosm and Fracture Research and Application Consortium (FRAC) at The University of Texas at Austin. Linda has published a number of papers touching on various aspects of diagenesis in peer reviewed journals and is an author of dozens of abstracts associated with presentations at scientific meetings.  She currently is an Associate Editor of the AAPG Bulletin.

Linda earned her Ph.D. in Geology from the University of Illinois in 1990 where she worked with Tom Anderson and subsequently held Research Associate positions at Washington University and Rice University where she worked with Lynn Walter and Rob Dunbar, respectively. She was a Senior Research Scientist with Rogaland Research in Stavanger, Norway from 1993 until 1997 when she joined Geologica AS, a spin off company. Linda co-founded Geocosm LLC in 2000 and holds the positions of Scientific Advisor and President. She also has an appointment as a Research Fellow at the John A. and Katherine G. Jackson School of Geosciences at the University of Texas at Austin.

Robert H. Lander

Partner/Scientific Advisor 

Rob Lander works with diagenesis and petrophysical models for Geocosm. He co-invented Geocosm’s Prism2D and Touchstone models and Geologica’s Exemplar® model and has worked extensively with basin models and geochemical reaction-path models.  He also developed Geocosm's COAN code for quantitative image analysis of grain coating characteristics.

Rob has published more than a dozen scientific papers in peer reviewed journals in the past 10 years in addition to being an author of more than 40 meeting abstracts in that time. He co-edited a special issue of the AAPG Bulletin on reservoir quality prediction in sandstones, was a co-convener of the AAPG Hedberg Conference Structural Diagenesis: Fundamental Advances and New Applications from a Holistic View of Mechanical and Chemical Processes, was awarded the best university presentation at the US Department of Energy Symposium "Flow and Transport: from Pore to Reservoir Scales" in 2002 by vote of fellow attendees, and gave a keynote talk on the state-of-the-art in sandstone diagenetic modeling at the SEPM Diamond Jubilee Symposium at the 2001 AAPG/SEPM meeting.

Rob obtained a Ph.D. in Geology from the University of Illinois in 1991 under the supervision of Dick Hay and was a Senior Research Geologist at Exxon Production Research from 1991 to 1993. He then joined Rogaland Research in Stavanger, Norway and was one of the founding staff members of a spin-off company (Geologica AS) in 1996 where he held the position of Scientific Advisor and later as Technical Director. Rob co-founded Geocosm LLC in 2000 where he is a Scientific Advisor and Partner. He also has an appointment as a Research Fellow at the John A. and Katherine G. Jackson School of Geosciences at the University of Texas at Austin.



Greg Carter

Senior Software Engineer
Greg Carter has been involved in virtually all aspects of Geocosm software development since he started working with us in 2006 but Geocosm's numerical kernel (TsLib) is his principal focus. He conducts C++ and Matlab development for the Windows and Linux platforms, .NET development on Windows, and created the XML schemas used by Touchstone and TsLib.

Greg received a Bachelor in Electrical Engineering from Carlton University in 1995. Prior to working with Geocosm he developed software protection products for a wide range of applications and platforms in addition to working on VPN systems.


William Croteau

Senior Software Engineer
Bill Croteau oversees software design and development associated with Geocosm’s Touchstone product and has worked with us since 2009. He is our resident.NET guru and makes extensive use of his expertise in C#, SQL, and XML, and a number of other technologies.

Bill has over 14 years of experience in object-oriented analysis, design and programming and has worked extensively with both client-side / graphical user interface (GUI) and back-end server design and development. He has a degree in Computing Science (with Honours) from Algonquin College.


Richard E. Larese

Scientific Advisor
Dick Larese is an independent consultant based in Durango, Colorado but works closely with Geocosm. Dick’s laboratory experiments of chemical and physical diagenesis are an integral part of Geocosm’s RQC research effort. He also has participated in a number of Geocosm reservoir quality prediction studies.

Dick received his Ph.D. in Geology from West Virginia University in 1974 under the supervision of diagenesis legend Milton Heald. He worked as a research scientist for Amoco Production Company from 1974 until he retired in 1999. While at Amoco he worked on clastic reservoir quality studies in support of the company’s worldwide exploration and production ventures and published several classic papers on sandstone diagenesis.

Dick was an AAPG Distinguished Lecturer in 1997-1998 and the topic of his lecture series concerned the primary controls on sandstone reservoir quality.
