About me
Welcome! I'm a recent grad pursuing a career in behavioral data science and quantitative research.
I created this site to share what I’m learning, highlight my work, and help others learn data science in a clear and approachable way.
Education
M.S. in Data Science - The University of Edinburgh (In Progress)
Moved to the UK to pursue advanced training in natural language processing, applied machine learning, and quantitative research.
B.S. in Cognitive Science - Lehigh University
This interdisciplinary program allowed me to explore the intersection of human behavior and data through coursework in psychology, machine learning, and artificial intelligence.
Concentration in Artificial Intelligence & Formal Models
Minors in Data Science and Business


Research Assistant - Nano Human Interfaces Lab
Developed mixed-reality human-machine interfaces with integrated eye-tracking on the HoloLens 2.
Enabling the capture of high-frequency behavioral signals for analysis.
Senior Marking Data Science Intern - Lehigh@NasdaqCenter
Applied time-series analysis, clustering, and demographic segmentation to optimize posting schedules and audience targeting.
Achieving 114% LinkedIn and 54% Instagram follower growth.
Data Science Intern - McCormick & Company
Data Science Assistant - McCormick & Company
Developed statistical risk models analyzing 3M+ consumer behavior data points over 15 years of time-series data to predict product reformulation success rates.
Developed an autoencoder-based anomaly detection system that analyzed over 7M consumer data points.
The system leveraged NLP to identify shifts in customer preferences and detect product performance drift.
