Alan D. Christian, Ph.D. leads marine and aquatic field operations and supports freshwater mussel and aquatic ecosystem investigations across the United States. Alan oversees teams of malacologists and commercial divers conducting underwater field surveys, endangered species consulting including biological assessments, underwater infrastructure inspections, and underwater construction for environmental and infrastructure projects, helping ensure high-quality field data collection and project delivery for clients and agency partners.
Alan earned a Bachelor of Science in Biological Science from the University of Wisconsin–Oshkosh, a Master of Science in Biological Science from Arkansas State University, and a Ph.D. in Zoology from Miami University. His academic training focused on aquatic ecology, freshwater mussel biology, and conservation science.
With more than 25 years of experience in aquatic ecology, Alan has conducted ecological investigations involving more than 150 freshwater mussel species, including numerous federally and state-listed taxa. His work includes basin-scale surveys, ecological monitoring, and aquatic habitat assessments across major river systems throughout the United States, working closely with federal and state natural resource agencies on endangered species conservation and environmental compliance projects.
Alan holds a lifelong passion for freshwater ecosystems. Outside of work, he enjoys spending time outdoors, traveling with his family, and cheering on his daughter as she competes in softball and equestrian events.
Few environmental firms in the country retain EnviroScience’s degree of scientific know-how, talent, and capability under one roof. The diverse backgrounds of our biologists, environmental engineers, scientists, and divers enable us to provide comprehensive in-house services and an integrated approach to solving environmental challenges—saving clients time, reducing costs, and ensuring high-quality results.
Our client guarantee is to provide “Excellence in Any Environment,” meaning no matter what we do, we will deliver on our Core Values of respect, client advocacy, quality work, accountability, teamwork, and safety. EnviroScience was created with the concept that we could solve complex problems by empowering great people. This concept still holds true today as our scientists explore the latest environmental legislation and regulations and incorporate the most up-to-date technology to gather and report data.
EnviroScience expertise includes but is not limited to aquatic surveys (including macroinvertebrate surveys and biological assessments); ecological restoration; ecological services (including impact assessments, invasive species control, and water quality monitoring); emergency response; engineering and compliance services; endangered mussel surveys; laboratory and analysis; stormwater management; threatened and endangered species; and wetlands and streams (including delineation and mitigation). Further, EnviroScience is one of the few biological firms in the country that is a general member of the Association of Diving Contractors International (ADCI) and offers full-service commercial diving services.
