Dr. Robert Gensemer has 35 years of academic and industrial experience in aquatic ecology and limnology, ecotoxicology, and the environmental toxicology of metals and polycyclic aromatic hydrocarbons (PAHs). His consulting project experience includes general aquatic toxicology, the conduct and oversight of ecological risk assessments for both aquatic and terrestrial habitats, sediment remedial investigations under the Environmental Protection Agency’s (EPA) Superfund program, and the development and modification of ambient water quality criteria for protection of aquatic life.

One of Dr. Gensemer’s primary areas of technical expertise is in the conduct and review of ecological risk assessments, primarily at contaminated sediment remediation sites under the auspices of EPA’s Superfund program. He has led both agency and industrial group risk assessment teams at some of the nation’s largest and most complex sediment Superfund sites including Portland Harbor and several sites on the east coast. At Portland Harbor, Dr. Gensemer led the consulting team support for EPA Region 10 in their oversight of the baseline ecological risk assessment phase of the remedial investigation.

Presently, Dr. Gensemer is the consulting project manager supporting a utility company in their participation in a Superfund sediment remedial investigation and feasibility study in the Greater New York area.
