Chen Zhu received a Master's degree from the University of Toronto and a Ph.D. degree from Johns Hopkins University (1992), before being awarded a post-doctoral fellowship at Woods Hole Oceanographic Institution. He subsequently worked for five years in the environmental industry, where he encountered many environmental problems first-band and routinely used geochemical modeling as a tool in his work. Dr Zhu is now an assistant professorat the University of Pittsburgh where he teaches courses in geochemical modeling.
Greg Anderson has been Professor of Geochemistry at the University of Toronto for 35 years and is the author of two textbooks on thermodynamics for Earth scientists : Thermodynamics in Geochemistry (1993) and Thermodynamàcs of Natural Systems (1995). In 2000 he was awarded the Past President's medal by The Mineralogical Association of Canada for contributions to geochemistry.
