Karsten Pruess was presented a Lifetime Achievement Award for Development of the TOUGH Codes on Tuesday, September 18th, at the 2012 TOUGH Symposium in Berkeley, CA.

Appreciations from the User Community
| Curt Oldenburg | TOUGH2 is my laboratory, field site, and customizable analytical tool all in one! I am deeply appreciative of the opportunities that TOUGH2 has given me in my research career. Thank you for this. |
| Stefan Finsterle | TOUGH2 is the powerful engine that enables iTOUGH2 to fly – thank you, Karsten, for building it, and thank you for all you taught me over so many years. |
| Nic Spycher |
And so, TOUGH gave birth to TOUGHREACT, giving reactive transport a whole new and exciting level. Thank you Karsten! |
| Jonny Rutqvist | TOUGH (with FLAC) provided me with an unimaginable world of multiphase flow and geomechanics applications and research collaborations. |
| Eric Sonnenthal |
One small step for TOUGH, one infinite domain for mankind. |
| Barry Freifeld | My domain of interest is making measurements in the real world – not a numerical model. But I have learned before going to the field, TOUGH is like the American Express Card – “don’t leave home without it. |
| Fabrizio Gherardi | Thanks for putting a good deal of ‘rigorous simplicity’ in my intrinsically ‘non-linear geochemical reasoning’. |
| Seyed Mostafa Salehi | I have two new idea for research as interdisciplinary projects 1-the earth electromagnetism2-the earth isostasy deformation & its affection on the earth climatology revolution & earth warming . |
| Paul Hsieh | Thank you, Karsten. Your development of the TOUGH codes has provided an invaluable tool for analysis and discovery in the geosciences. |
| Alexey Kiryukhin | Karsten Pruess created a tool, which integrated hydrogeology, geophysics, geochemistry, engineering geology, geothermal and environmental in one science. The name of the tool is TOUGH2. |
| T. Dung TRAN | Without TOUGH2 many interesting research papers would not be released. TOUGH2 has had the family of three generations and will see so on, I think. Thank you, the Grandfather, for TOUGH2. |
| Jonathan Ennis-King | The extensibility of the TOUGH codes have been ideal for meeting research challenges in modelling underground storage CO2. Thanks Karsten for your innovation and generosity. |
| Steve Webb | Karsten – Thanks for developing the code and for your friendship and collaboration over the past 20+ years. It was always enjoyable working with you!! |
| Daniel Swenson | I am sitting here working on the user interface for ECO2M and just wanted to thank you for all your work on TOUGH2. Your vision, precision, and generosity have made these codes a wonderful resource. Of course, Thunderhead would not exist without them. |
| Tony Menzies | Congratulations; well deserved. Thanks for the friendship over the years and looking forward to a beer next time I’m in Berkeley. And thanks also the interaction and help with the going got TOUGH…2. |
