Greg E. Challenger, M.S
President
Mr. Challenger is a marine ecologist with expertise in environmental resource management, coral reef damage assessment, oil and chemical spill assessment and habitat restoration. Mr. Challenger has been involved in assessing NEARLY 200 large oil spill, pipeline, railroad and ship grounding incidents in the past 30 years, working with government and industry to study impacts and find restoration-based solutions to environmental casualties.

Dr. Elliott Taylor
Principal
Dr. Taylor is a scientist with over 30 years of experience in environmental and marine sciences. His projects in oil spill response include planning, regulatory compliance, spill exercises, response evaluation, technical support in environmental and shoreline assessment, baseline studies, sediment quality and transport, coastal processes and marine geology.

Andrew W. Graham, M.S.
Principal/Marine Scientist
Mr. Graham has responded to over 70 large vessel incidents & groundings, train derailments, pipeline spill and other incidents in the past 18+ years, working with government and industry to find restoration-based solutions to environmental casualties in the marine and inland environments. He also is a Geographic Information Systems (GIS) specialist for Polaris, utilizing GIS software to generate maps to aid emergency response operations and natural resource damage assessment studies.

Travis Scott, M.S.
Environmental Scientist
An experienced field scientist and accomplished SCUBA diver, Mr. Scott performs scientific dives for coral reef damage assessment, coral reef restoration and salvage support and shoreline surveys for oil and chemical spill assessment and habitat restoration. Mr. Scott has responded to over 20 vessel and pipeline incidents over 10+ years and has throughout his career worked closely with government, industry, academia and non-profit sectors with are cent emphasis on restoration-based solutions to marine injury cases.

Samantha Iliff, M.S.
Environmental Scientist
Ms. Iliff is an ecologist with experience in coastal habitat restoration, ecosystem ecology, marine pollution science, and statistics. She has 8+ years of research experience focused on understanding the impacts of pollutants on marine ecosystems and advancing the science that underpins NRDA restoration scaling in coastal environments. Her research includes studies of how ecosystem services are both lost through human interactions and gained through restoration. Her work has spanned various regions and habitat types including seagrass beds, coral reefs, mangrove forests, oyster reefs, salt marshes, sandy beaches, rocky intertidal, and riverine ecosystems.

Alison Craig, M.S., M.P.A.
Environmental Scientist
Ms. Craig provides over 20 years of experience in oceanography, environmental monitoring, ecological risk assessment, and natural resource management. For the past 10 years Ms. Craig has been involved with spill response, prevention, and contingency planning. She has assisted with the preparation of numerous integrated spill response plans for regulatory compliance, spill response tactics manuals, and designed and developed databases in support of regional, national, and international spill response planning and preparedness.
