Research Interests: Environmental Mineralogy, Crystallography and Crystal Chemistry

My research interests involve the integration of low temperature geochemistry and mineralogy in the study of crystal surfaces and water-rock interactions found in natural systems. In particular, I am interested in environmentally significant processes such as crystal growth, metal sorption, trace element partitioning and other surface mediated reactions. My research also addresses the structural response of minerals to substituent elements, especially lanthanides and actinides in apatite group minerals.

Current research projects include: Use of phosphate minerals for environmental remediation; the role of crystal surface structure on trace element incorporation during growth; crystal chemistry of the lanthanides and actinides in apatite; crystal growth and trace element incorporation in fluorite and apatite; understanding fundamental interactions between aqueous metal species and soil minerals; mineral replacement reactions.
