My research focuses on fundamental aspects of mineralogy including as crystallography, crystal chemistry, and crystal growth, with an emphasis on their connection to environmental and technological uses of minerals, and mineral deposit formation. Much of this work deals with apatite supergroup minerals, native metals and clay minerals.
