James W. Ward, Ph.D., P.G.

My current interest are in Hydrogeology, Aqueous Geochemistry and traditional Field Geology. I teach a variety of classes here at ASU including Physical Geology, Historical Geology, Introduction to Hydrogeology, Introduction to Geochemistry, Geomapping Fundamentals (GIS), Field Methods in Geology/Hydrogeology, and Summer Field. I am working on a variety of hydrogeology related projects with my research cluster of Senior RA’s including contaminant hydrology, water budgeting, aquifer modeling, etc. I am also the Advisor of our Geoscience Honor Society, the Theta Gamma chapter of the Sigma Gamma Epsilon and co-advisor of the GEO Club.

Heather L. Lehto, Ph.D.

My research focuses on shallow volcanic processes imaged through seismicity. Specifically how magmatic processes can alter the local stress field at volcanoes and how seismology can be used to image the magma plumbing system. I am also interested in creating and assessing new and innovative teaching tools as part of my research into Geoscience Education
