Expert Witness Network

Water Chemistry
Dr. Brian Dempsey, Professor of Environmental Engineering at Penn State for over 25 years, is an expert in water chemistry issues. He has provided expert opinions in cases concerning water treatment and hazardous waste sites.

Dr. Dempsey is widely recognized for his research on water and wastewater treatment. His research includes the development of methods for producing consistently clean drinking water from contaminated sources and a USGS-funded project concerning eutrophication of Chesapeake Bay. He has published extensively on acid mine drainage and the removal of arsenic from drinking water.

Dr. Dempsey is a member of the American Chemical Society, American Society of Engineers, American Water Works Association, Association of Environmental Engineering and Science Professors, The Geological Society of America, and the International Water Association.

Dr. Dempsey has B.S. degrees in Chemistry and Inter-Disciplinary Sciences, and an M.S.P.H. and Ph.D. in Environmental Chemistry and Biology.

Toxicology
Dr. Richard Troast, an environmental toxicologist, is an expert in lead, arsenic, asbestos, VOCs, and other chemicals among the many compounds regulated by the USEPA Superfund and Hazardous Waste Programs. His experience also includes risk assessment modeling for radon in indoor spaces and assessing toxicity of radionuclides in drinking water.

As a senior scientist at the USEPA Dr. Troast’s career included managing the EPA Workgroup on Metals and Asbestos which had oversight of national level projects. Since retiring from the EPA Dr. Troast has worked overseas developing a RCRA style hazardous waste control system, which included a laboratory assessments program, supported legal firms with expert testimony on metals and asbestos, and taught at local colleges and universities as an adjunct professor.

Dr. Troast has a B.A. degree in Biology, M.S. in Biochemistry, and Ph.D. in Environmental Science and Policy.

Corrosion
Dr. Barbara Shaw, Professor of Engineering Science and Mechanics at Penn State, is an expert in corrosion. She provides expertise in cases concerning industry standards for corrosion protection of metallic piping systems, tanks, and machinery as well as corrosion-related failure mechanisms.

She has served as an expert witness in a trial involving the corrosion of fire hydrants and has considerable research and consulting experience concerning such topics as the development of corrosion-resistant materials and coatings, corrosion mechanisms, corrosion assessment, and cathodic protection and has published extensively on these subjects.

Dr. Shaw is an active member of a number of corrosion-related professional societies including NACE International, the Electrochemical Society, and ASTM. For the past 16 years, she has directed and taught a corrosion short course for professionals in corrosion-related industries and government labs.

Dr. Shaw has a B.S. degree in Ocean Engineering and M.S. and Ph.D. degrees in Materials Science and Engineering.

Remote Sensing and Photogrammetry
Karen Schuckman, is Senior Lecturer in Geography at Penn State University, teaching remote sensing and geospatial technology in the online programs offered by the John A. Dutton e-Education Institute. She provides expert knowledge in remote sensing and photogrammetry to engineering practice groups, including floodplain mapping, disaster response and preparedness, critical infrastructure, and transportation.

From 1995 - 2005, she was with the EarthData group (now Fugro EarthData), where she held several positions including geospatial applications director for EarthData Solutions, senior vice-president of EarthData Technologies, and president and general manager of EarthData International of North Carolina. Prior to joining the private sector, Karen worked for the USGS National Mapping Division in Menlo Park, California. She has served as President of the American Society for Photogrammetry and Remote Sensing (ASPRS) from 2005-2006, vice-chair of the NOAA Advisory Committee on Commercial Remote Sensing (ACCRES), member of the National Research Council's Committee on Floodplain Mapping Technologies and the Committee on FEMA Flood Maps. She is an ASPRS Certified Photogrammetrist (CP) and a Professional Land Surveyor (PLS) licensed in North Carolina.

Ms. Schuckman has a B.S. degree in Meteorology and a M.S. in Geographic Information Systems from Penn State.
