Current Academic Interests

Much of my effort in the past few years has been in the realm of outreach to science teachers in the public schools. I developed Geology’s first totally online lecture/lab course for introductory geology and taught it to elementary and middle-school, pre-service teachers in spring, 2009. ECU has several totally online degrees and an online geology course is a necessary addition to those programs. I have also written and submitted several large proposals (~$470K to $3.5 million) to generate funding to facilitate the use of hands-on, inquiry-based science instruction in public schools in northeastern North Carolina. This region has the poorest passing rates on end-of-year science tests in the state, as well as some of the lowest enrollments in advanced science courses in high school. At least one of these proposals is still pending and may be funded. I am also continuing my work with the Burroughs Wellcome Fund board overseeing selection of recipients for their Student Science Enrichment Program grants (~$180K over 3 years) and every year I organize 4-5 groups of graduate students to run events at the regional Science Olympiad tournament held at ECU each spring. Finally, I am still actively engaged with the Center for Inquiry-based Learning ( participating in their efforts to enhance hands-on, inquiry-based science education.


Some of my scientific research has taken a new track and is focused on formation of oxidized copper minerals in water at Earth’s surface. I am also continuing to write up the results of the Reverse Osmosis project - “Ecological Assessment of Reverse Osmosis Water Treatment Plant Discharge Sites, Present and Proposed, in Coastal Waters of Northeastern Albemarle Sound”. This project was begun by Roger Rulifson (ICSP and Biology) and he subcontracted the water quality and sediment evaluation work to me. From July, 2005 through June, 2006 we collected approximately 40 samples every two weeks to be analyzed for major elements and nutrients.  I continue to teach undergraduate Mineralogy/Petrology, Physical Geology, Oceanography, and graduate Geochemistry regularly.
