The Econ Data Lab Champaign, IL

Undergraduate Researcher 08/2024 - Present

• Conducting cross-national research analyzing the impact of living arrangements and sociodemographic factors on mental health among older adults

• Leveraging data in python from global aging surveys, targeting CESD-10 screening results as a metric for depression

• Implemented logistic regression models in India and China, finding that in China, individuals living alone were 1.44x more likely to be depressed

• Utilized Synthetic Minority Over-Sampling to address class imbalances in India survey collection, making predictors 4x more statistically significant

Applied Technologies for Liberal Arts and Sciences Champaign, IL Intern, Business Process Improvement, ATLAS Internship Program 05/2024 - 08/2024

• Developed and deployed a digital record-keeping solution for the Division of Public Safety’s i-PAWS program, streamlining efficient tracking of K-9 interactions and training

• Optimized workflow management by designing a structured form-based system, incorporating automated approvals, intern assignments, and archival tracking to enhance ATLAS intern project intake and coordination.

Projects

CrowdStrike Outage Case Study (Python) 07/2024 - 08/2024

• Implemented causal inference techniques to assess the impact of a widely reported computer outage on CrowdStrike’s stock price, incorporating time series data from multiple relevant companies

• Identified and validated a 10% return decrease as a direct result of the CrowdStrike outage, using a difference-in-difference model to compare CrowdStrike as a treatment, and other stocks as a control Analysis of Student Activities on Class Performance (R) 01/2024 - 04/2024

• Utilized multiple regression analyses on over 2,000 individuals to assess the impact of study hours, absences, extracurricular participation, and employment on exam performance.

• Implemented data transformations and residual analysis to correct for non-linearity and heteroscedasticity, enhancing the reliability of insights into factors that influence performance. Housing Price Forecast (Python) 08/2024 - 12/2024

• Completed an end-to-end data science project, including data cleaning, exploratory analysis, feature engineering, predictive modeling and model evaluation

• Leveraged Python and key libraries such as Pandas and NumPy for data manipulation, Matplotlib for visualization and Scikit-learn for machine learning workflows, including feature scaling and encoding via pipelines.

• Improved predictive accuracy by reducing RMSE scores by 16.7% through advanced data preprocessing Activites

The Scholarly Reading Circle For Economics Champaign, IL Co-President 01/2024 - Present

• Organized and led data science workshops for 50+ economics students, featuring live demonstrations in Python and R on topics like data visualization, time series forecasting, regression, and data cleaning
