Kimberley Maldonado

Data scientist with a background in fashion, healthcare, and behavioral research. I build interpretable, human-centered models that bridge technical rigor with creative insight spanning customer segmentation, medical decision-making, and recommendation systems.

• TENNIS ANALYTICS, Stevens Institute of Technology, BIA 678: Big Data Technologies, 09/24-12/24, Simulated user behavior and modeled engagement outcomes in a sports content setting, applying audience segmentation and predictive techniques analogous to ad tech and audience targeting use cases., Engineered 12+ features including player profile, experience, and competitive behavior to train a Random Forest model (74% accuracy) and simulate round-by-round tournament progression., Conducted player trend benchmarking (e.g., Coco Gauff, 2019-2024), identifying engagement drop-off points and improvement opportunities., Applied modeling and statistical reasoning end-to-end to real-time decision problems, analogous to ad targeting and cohort segmentation.
• FINANCIAL VOLATILITY FORECASTING, Stevens Institute of Technology, MA 641: Time Series Analysis I, 05/24-09/24, Examined retail sales data (FRED) and Apple stock closing prices, capturing seasonal and nonseasonal financial patterns., Analyzed market volatility trends, quantifying the impact of economic events like the 2008 financial crisis and COVID-19., Applied Box-Jenkins methodology, optimizing ARIMA-GARCH models for accurate volatility forecasting., Performed rigorous model diagnostics (QQ plots, Ljung-Box tests) to validate results, improving forecasting accuracy.
• ITALIAN AIR QUALITY MODELING, Stevens Institute of Technology, MA 544: Numerical Linear Algebra for Big Data, 09/23-12/23, Analyzed UCI Air Quality Dataset to identify major contributors to pollution in an Italian city., Developed and compared Linear Regression, KNN, and Decision Tree models for pollution level forecasting., Applied PCA and K-Means clustering to uncover daily and hourly pollution patterns, enhancing interpretability., Evaluated the impact of human activity on air quality through time-based pollution pattern analysis.

PRESIDENT, STEM STUDENT UNION, Bergen Community College, 2016-2017, Elected leader of STEM-focused student body; organized research conferences and advocated for student project funding.
