dGB management
	Nanne Hemstra is Executive Vice President - Americas and a senior geo-scientific software engineer. He can be considered as one of the founders of OpendTect, and he has been involved in almost all OpendTect developments since he started working for dGB in 2001. He is responsible for many innovations and he is currently developing sequence stratigraphic functionalities for OpendTect. Nanne studied geophysics at Utrecht University where he specialized in exploration geophysics. From 2007 to 2011 Nanne was Executive VP of dGB-India, the branch office he helped to build up from scratch.
	Friso Brouwer Chief Operating Officer - Americas, joined dGB in 2002 after completing a MSc in Applied Geophysics at Delft University of Technology. His primary areas of expertise are seismic attributes, application of neural networks on seismic data, inversion & reservoir characterization. Friso has made important contributions in product and workflow development for OpendTect. His scientific focus is to further develop integration of geology and geophysics with the aid of advanced interpretation tools such as seismic attributes, seismic charge and seal analysis, SSIS, DHI analysis and rock property transforms.
Special Adviser
	Fred Aminzadeh has been instrumental in the start up and growth of dGB Earth Sciences in the United States for almost 10 years. He worked 17 years for Unocal in technical and management positions. Fred has authored many books, patents and articles on different aspects of geophysical technology, including modelling, seismic attributes, seismic processing, AVO and reservoir characterization. Fred earned his PhD from the University of Southern California. He has served as SEG president and as chairman of SEG's research committee for two years. He was the recipient of the SEG's Special Commendation Award for leading and successfully completing a $ 25 Million Industry / Government supported project on 3D Salt and Overthrust Modelling. Fred is currently a research professor at University of Southern California and President of FACT.
Case studies
	David Connolly has joined dGB Earth Sciences in 2002 as Chief Geologist. He has over 20 years of industry experience in various aspects of petroleum geology and geophysics. Formerly with Texaco, he has worked on a variety of international and national exploration assignments. His areas of expertise include reservoir characterization, sequence stratigraphy, integrated seal analysis, petroleum migration and 3D visualization. He has co-authored various talks and poster sessions on deep water technologies. Prior to joining Texaco, he worked as core analyst and laboratory manager for Schlumberger-Anadrill. He is mainly involved in seismic object detection and interpretation studies, especially on fluid migration.
	Renee Bourque joined dGB Earth Sciences as a Geoscientist in September 2008. Her focus at dGB is Seismic Sequence Stratigraphy using the OpendTect SSIS plugin. Renee received her undergraduate degree in Geology from Texas A&M University, and her MSc in Hydrogeophysics from the State University of New York at Buffalo.
Software development
	Yuancheng Liu has joined dGB Earth Sciences as a research scientist. He received his PhD in mathematics from the University of Houston. His specialty is modeling and data analysis. He will apply his mathematical and statistical skills in processing and interpreting multi-volume seismic data as well as implementing new algorithms within OpendTect.
