Mr. Ken Unice is a Principal Science Advisor with 18 years of quantitative human health risk, exposure assessment, and environmental modeling experience. His expertise is in the areas of environmental modeling, biokinetic modeling, indoor air modeling, occupational exposure assessment, human health risk assessment, environmental fate and transport analysis, computer programming and database design. Mr. Unice has co-authored more than 40 peer-reviewed journal articles and more than 100 conference abstracts on the topics of biokinetic modeling, biomonitoring, environmental fate and transport models, metals exposure, pathogen risk assessment, exposure reconstruction, and subsurface bacterial transport. He has expertise in the implementation of various numerical integration methods and has developed finite-difference computer models in programming languages such as Visual Basic, C++, Fortran and MATLAB and has performed several probabilistic assessments. Mr. Unice is proficient in a variety of mass-transfer theories used to estimate the fate of chemicals in the environment.
Mr. Unice has managed exposure assessments, risk assessments, and risk ranking evaluations for a variety of occupationally and commercially important compounds, and has particular expertise in applying modeling techniques in the areas of product stewardship, toxicology, occupational health, and human health risk assessment. He has served as an invited peer reviewer of several U.S. EPA technical approach documents or proposed models, and recently served on the peer review panel for the U.S. EPA technical approach document entitled “Approach for Estimating Exposures and Incremental Health Effects from Lead due to Renovation, Repair, and Painting Activities in Public.” Mr. Unice has completed third-party reviews for state environmental agencies, and has performed critical reviews of a variety of modeling assessments.
In addition, Mr. Unice also has extensive experience in applied research and study design, as well as managing contract research organizations. He has published methods for the characterization of tire and road wear particles (TRWP) in air, soil and sediment, as well as methods for characterizing the fate of individual chemicals used to formulate tire tread. Mr. Unice has also published methodologies for assessing the distribution of cobalt in the human body, estimating chemical exposure during consumer use, reconstructing human exposures associated with historical stack emissions, and modeling of dispersion and blocking of bacteria in subsurface media. Mr. Unice is proficient in both deterministic and probabilistic exposure assessment methods for metals, volatile organic compounds, and inhalable fibers. He has performed modeling evaluations or analytical assessments in a number of industries, including the rubber, energy, chemical manufacturing, household consumer product, paper products recycling, and construction.
