I have vast experience working on granitic pegmatites and have visited over 100 of them. I have conducted geochemical and petrographical research on granitic pegmatites in California, Maine, North Carolina and Virginia.

Was co-leader in several "PEGCAMPS" in Maine, Colorado and Southern California. Pegcamps are a one week, intensive field camp to instruct students on aspects of pegmatite mineralogy, petrology, formation, field identification and exploration.
