Dr. Michael Bock is a Managing Director with experience in environmental science and consulting. He specializes in the investigation and assessment of contaminated marine and freshwater sediments, including statistical analysis, forensic analysis and source allocation, fate and transport modeling, species sensitivity toxicity evaluations, and ecological and human health risk assessment. His expertise includes using multivariate statistical data analysis such as multicriteria analysis and receptor modeling/source unmixing (e.g., principal components analysis, hierarchical cluster analysis, ratio analysis, least-squares mixing models, cosine-theta analysis, and polytopic vector analysis), to determine fingerprint patterns and allocate sources in environmental samples. His environmental forensic work has focused extensively on discerning sources and the fate of polychlorinated biphenyls (PCBs), dioxins and furans (PCCD/Fs), Per- and polyfluoroalkyl substances (PFAS), polycyclic aromatic hydrocarbons (PAHs), and metals in rivers, lakes, ports, harbors, groundwater, and soils. He has developed multimedia fate and transport models that are used to model organic chemicals in the environment, during wastewater treatment, and in land applied biosolids. These models have been used to assess the concentration, persistence, treatability, bioaccumulation, and weathering of chemicals in the environment. His experience also includes exploratory data analysis and visualization; conventional, probabilistic, and Bayesian statistical analysis; simulation studies; mathematical modeling; computer programming and automation; database design and management; the critique of chemical analysis methods; data quality; and usability evaluations.
