Current Research and Scholarly Interests

Research
I am interested in the process of building numerical models of the space-time distributed phenomena that are found in Earth sciences. How can such models integrate data of different sources, different scales and reliability, both hard and soft, and at the end provide a basis for a numerical assessment of the phenomenon being studied including space extrapolation and time prediction? The mathematics and algorithmic parts of the building process are of greater interest to me than any particular application, although any model must be judged by its applicability to real data and ability to solve real questions. Recent applications are in modeling hydrocarbon reservoirs, air pollution spread, and urban growth. For the last few years at Stanford I have been editing a major book, SGEMS: User’s Manual and Software, related to the new C++ freeware Stanford Geostatistical Earth Modeling Software. The book is authored by three of my students, Nicolas Remy, Alex Boucher, and Jianbing Wu, and was published by Cambridge U. Press (2008).

Teaching
As an emeritus each Spring quarter I teach an advanced PhD level seminar ERE240

Professional Activities
Election to the National Academy of Engineering (1998); director, Stanford Center for Reservoir Forecasting (1984-1997); editor-in-chief, Oxford Press Applied Geostatistics Series (until 2009); editorial board member, Mathematical Geology
