Dr. Nicos S. Martys

Dr. Nicos S. Martys is a physicist in the Inorganic Materials Group of the Materials and Structural Systems Division (MSSD) of the Engineering Laboratory (EL) at the National Institute of Standards and Technology (NIST). Dr. Martys joined the Inorganic Building Materials Group of the Building Materials Division in October 1992. Dr. Martys research interests include the rheology of complex fluids and transport in porous materials. He has developed state of the art multi-scale computational models of suspensions for application to the flow of cement based materials. These models can account for cement, sand or aggregate shapes, inter-particle interactions and the non-Newtonian nature of a matrix fluid that contains the solid phase. He has also made both theoretical and computational advances in the modeling of single and multi-component flow in complex geometries like porous materials including micro porous materials described by multiple characteristic pore sizes.

Prior to becoming a staff physicist at NIST, Dr. Martys was a NIST/ASEE Postdoctoral Fellow from 1990 to 1992. In 2009 Dr. Martys was awarded the DOC Silver Medal for his contributions in the computational materials science of concrete for the Virtual Cement and Concrete Testing Laboratory (VCCTL).

Dr. Martys is currently a member of the Society of Rheology. He has served as an editor for the NIST Journal of Research and has been a member of the American Physical Society, American Ceramics Society and the Materials Research Society.
