Developed a system dynamic optimization model for a commercial aquaponic firm, integrating biophysical and economic components to optimize production and resource use.

Constructed growth functions for plants and fish—using a logistic model for kale based on biophysical data and a hybrid thermal unit–logistic model for fish—to capture biological dynamics in controlled environment agriculture.

Enhanced the model’s nutrient interaction mechanisms and applied Faustmann Rotation theory to identify the optimal management strategy balancing biological growth and economic returns.

Employed unsupervised natural language processing techniques to categorize academic papers into methodological groups using keyword extraction from titles and abstracts with regular expressions.

Utilized statistical and visualization packages to produce cumulative time-series charts and heat maps for literature trend analysis.

Assessed consumer responses to environmental contamination by analyzing bottled water sales after the 2015 Gold King Mine spill using Nielsen Consumer Panel data (2011–2020).

Applied a Difference-in-Differences (Diff-in-Diff) framework to reveal preferences for clean water and estimate the lower bound of willingness to pay to avoid environmental health risks.
