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.

  • Douglas Jerolmack

    Associate Professor

    Doug Jerolmack, PhD focuses his research on the spatial and temporal evolution of patterns that emerge at the interface of fluid and sediment on Earth and planetary surfaces. Scales of interest range from ripples and dunes evolving over minutes in sandy rivers, to the preserved record of millions of years of coastal evolution on the continental shelf. He iterates between mathematical modeling, laboratory experiments and field observations in order to elucidate the minimum number of ingredients that are required to explain physical phenomena. While his interests are wide ranging, they share a common theme: to understand the internally generated dynamics of sedimentary systems, to characterize the response of the complex systems to changes in boundary conditions such as climate and to develop methods for accurately separating the two signals.

  • 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 over 20 years’ experience in water resources, hydrogeology and environmental engineering. His hydrology experience has ranged from evaluating water harvesting in semi-arid regions of Africa to determining protective discharge limits based on low flows in Pennsylvania streams. 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/Hydrogeologist Consultant at Pennoni Associates Inc., Tony also shares from his practical experience through teaching Hydrology at Penn and serving as a professional mentor to the Penn Engineers without Borders (EWB) water projects in Honduras 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.
