Quantifying the effect of urbanization on aquatic stream biota (macroinvertebrates, algae, and fish) at multiple scales using innovative hierarchical multilevel techniques and Bayesian networks. Developing a method for parameterizing the Biological Condition Gradient (BCG) for Effect of Urbanization on Stream Ecosystems (EUSE) dataset, incorporating expert.

OPPTS [2004-2006]: Synthesized multiple scientific sources of information (lab studies, models, expert judgment) to predict integrated pesticide fate in various application scenarios. Reviewed pesticide environmental fate studies for scientific validity, logic, and coherence. Modeled hydrolytic, photolytic, and metabolic breakdown of pesticides of varying.

Collected, quality controlled and analyzed complex data sets of air pollution concentrations. Used linear and nonlinear multivariate regression to predict 24-hour gravimetric PM2.5 concentrations from hourly TEOM, beta-gauge and nephelometer measurements, accounting for meteorological influence (temperature and humidity).

Translated and statistically analyzed Ukrainian, Russian, and Belarusian medical data collected as part of an epidemiological study to link occupational exposure to effects on coal miner lungs. Collaborated with doctors who administered physical exams and x-rays to demonstrate the detrimental effects of coal mine exposure on miners. Informed occupational.

Created and implemented quality control test plans for new versions of software for an online testing company. Meticulously discovered and cataloged new functionalities, foresaw potential interactions with old functionalities, and logically planned out how each was to be verified. Manipulated new and complex software code. Collaborated with senior computer.

Designed study of high school learning capacity for science as part of a research team developing a software program for use in a diverse range of classrooms to interactively teach students investigative and analytical skills by conducting simulated scientific experiments. Critiqued exploratory tests about natural selection and analyzed subsequent student.
