Staff Scientist, Earth Sciences Division,
Lawrence Berkeley National Laboratory (LBNL)

Carl Steefel has over 21 years of experience in developing models for multicomponent reactive transport in porous media and applying them to topics in reactive contaminant transport and water-rock interaction.  The reactive transport software CrunchFlow, for which he is the principal developer, is the culmination of this work.  He investigated geochemical self-organization and complexity theory in water-rock interaction (Steefel and Lasaga, 1990), while also developing the first routine for multicomponent nucleation and crystal size distributions in the Earth Sciences (Steefel and Van Cappellen, 1990).  Soon after, he presented  the first multicomponent, multi-dimensional  code for simulating water-rock interaction in non-isothermal environments (Steefel and Lasaga, 1994).  Steefel applies reactive transport modeling to such diverse settings as hydrothermal, contaminant, chemical weathering, and marine environments.  Recently, he has been involved in experimental studies of cation exchange (Steefel et al., 2003) and mineral dissolution and precipitation (Yang and Steefel, 2008), as well as modeling studies of field systems  focused on contaminant transport, microbially-mediated biogeochemical reactions, and chemical weathering (Giambalvo et al., 2002; Steefel, 2004; Maher et al., 2009; Li et al., 2009; Steefel and Maher, 2009).
