Faculty Bios

The outstanding faculty in the Master of Science in Applied Geosciences (MSAG) program brings a combination of world-class academic research skills and real-world experiences to the classroom. MSAG faculty are deeply invested in mentoring and guiding students to finding the best uses for their experience and education both at Penn and in their careers beyond the Applied Geosciences program. Students work closely with these faculty and many others on independent study and capstone research projects.

  • Maria-Antonia Andrews

    Associate Director, Undergraduate Programs in Earth & Environmental Science

    Maria holds a Bachelor of Arts in chemistry from Rutgers University and a Master of Science in engineering geology from Drexel University. Maria's professional experience in the environmental field ranges from applications of analytical soil and water chemistry to multiple facets of environmental consulting. Her focus of interest has been the behavior and interaction of inorganic and organic pollutants in the environment. Maria has been teaching at Penn since 2002 and is currently the Associate Director for Undergraduate Programs in Earth & Environmental Science.

  • Timothy D. Bechtel

    Lecturer, Master of Science in Applied Geosciences Program

    Tim Bechtel, PhD, PG grew up on the Rockdale Run Formation, with a sinkhole in the backyard of his boyhood home. He has a Bachelor of Science from Haverford College (where he majored in geology at Bryn Mawr College), and an Master of Science in Rock Mechanics and a PhD in Geophysics (focusing on gravity) from Brown University. The Fortran code Tim developed for calculating lithospheric loading and strength from the coherence of gravity and topography data was later developed by Dr. Anthony Lowry of Utah State University into the MECAIR (Maximum Entropy Coherence Analysis of Isostatic Response) package used by several dozen researchers throughout the world, and figuring prominently in the dissertations of at least 10 young scientists.

    Following several years working as a geophysicist for firms in Boston, Mass., and Harrisburg, Pa., Tim was a founding principal (in 1992) of Enviroscan Inc.—performing geophysical investigations and geophysical logging all over the world for environmental, hydrogeological, geotechnical, archaeological and law enforcement investigations. Tim is a guest editor for geophysical submissions to Hydrogeology Journal, and coauthor of the international textbook Methods in Karst Hydrogeology. He is a member of international scientific collaborations that are funded by NATO and the US-Russia-Japan-EU International Science and Technology Center (ISTC) to study novel technologies for humanitarian de-mining, remote detection of disaster victims buried beneath rubble, avalanches, etc., and nondestructive subsurface testing for historic and cultural preservation.

  • Mitch Cron

    Lecturer & Advisor, Master of Science in Applied Geosciences

    Mitch Cron has a Bachelor of Science degree from Villanova University and a Master of Science in Applied Geosciences from Penn. He has worked in the environmental industry since 1994, holding positions in the private sector and government. Mitch has taught earth science courses at area universities since 2014 and is currently an academic advisor and lecturer for the graduate geosciences program at Penn.

  • Edward Doheny

    Lecturer and Academic Advisor, Master of Science in Applied Geosciences

    Edward Doheny, PhD, PG is an academic advisor and lecturer for the Master of Science in Applied Geosciences Program (MSAG) which he helped found in 2005. Prior to joining Penn in 1993, Dr. Doheny was director of the Engineering Geology Program at Drexel University. He earned his Bachelor of Science from The City University of New York and his master’s and doctoral degrees in geology from Indiana University. Dr. Doheny also holds a Professional Geologist license from the state of Pennsylvania.

    In addition to being part of the Education 100, Dr. Doheny has received many honors for his contributions to education, including a Plaque of Appreciation from the Geography National Honor Society; an Outstanding Professor Award from the Pennsylvania Section of the American Institute of Professional Geologists; Penn’s Ferdinand Vandiveer Hayden Award for Distinguished Teaching and Career Mentoring of Students; the Christian R. and Mary F. Lindback Foundation Award for Distinguished Teaching and several other awards for distinguished teaching from Drexel University.

  • George E. Duda

    Lecturer, Master of Science in Applied Geosciences

    George E. Duda P.E., has more than 30 years experience in the construction industry, specializing in project and construction management, engineering analysis and design, construction, resolution of construction claims and litigation support. George’s projects include bridges, highways, airports, railroad facilities, rail transit car procurement, educational facilities, electrical generating stations, high rise commercial buildings, landfills and various smaller projects. He holds B.S. and M.S. degrees in civil engineering as well as an M.S. in engineering geology from Drexel University.

  • Chad Freed

    Lecturer, Master of Science in Applied Geosciences

    Chad Freed, PhD, is currently a tenured Professor of Environmental Science at Widener University and Director of the Geographic Information Systems and the Engineering and Environmental Geosciences Laboratories. At Widener University, he teaches undergraduate and graduate classes in the engineering and environmental geosciences, as well as supervising an active research program in the three-dimensional spatial characterization and visualization of geographic, hydrologic and geophysical data. Currently, his research projects include quantifying landscape disturbances from natural gas mining, and several conservation biology and climate change projects in Pennsylvania and New Jersey. His international research projects include global climate change analysis in the mountains of Costa Rica, the Amazon rainforest of Peru and modeling natural ecosystems on the Tibetan Plateau of China. His work on developing a shade tree inventory for the city of Chester, PA has been funded by the Harford Foundation and his work on hydrologic modeling in Chester has been funded by the Pennsylvania Sea Grant program. Past projects in Chester include quantifying ecosystem services provided by trees in DeShong Park and along the proposed cultural corridor as part of the Obama Administration’s Strong Cities Strong Communities (SC2) program.

  • Carl Mastropaolo

    Lecturer, Master of Science in Applied Geosciences

    Carl Mastropaolo has a Bachelor of Science degree in mathematics from St. Joseph's University and a Master of Environmental Science degree from Drexel University. He has been employed in the environmental consulting field for 16 years, the last 12 as a self-employed environmental scientist. Prior to his employment in the Applied Geosciences graduate program at Penn, he was an adjunct assistant professor in the Engineering Geology graduate program at Drexel University from 1991 through 2002.

  • J. Anthony Sauder

    Lecturer, Master of Science in Applied Geosciences Program

    Tony Sauder is a registered professional engineer and geologist with more than 30 years of experience in water resources, hydrogeology and environmental engineering. His hydrology experience has ranged from evaluating water harvesting in semi-arid regions of Africa to testing a high capacity public water supply well in New Jersey to determining protective discharge limits based on low flows in a Pennsylvania stream. His international experience includes 10 years working on projects involving water supply and sustainable development in Chad, Sudan, Honduras, the Dominican Republic and Belize. In his water supply and community development work, Tony has sought to facilitate access to water and communicate the benefits of improved water sources and sanitation on health. While working as Senior Engineer and Hydrogeologist at Pennoni, Tony shares his practical experience through teaching Hydrology at Penn. He also serves as a professional mentor to the Penn Engineers without Borders’ (EWB) water and sanitation projects in Honduras, Guatemala and Cameroon. Tony received his Master of Science in Civil Engineering from Drexel University in 1996 along with his Master of Science in Engineering Geology with a concentration in hydrogeology.
