I analyze user behavior to understand why people hesitate, drop off, or fail to act in digital systems, using behavioral data and HCI-informed reasoning.

I focus on explaining why users behave the way they do, especially in moments of hesitation, confusion, or disengagement.
Rather than optimizing interfaces or models in isolation, my work emphasizes behavioral interpretation — identifying cognitive, contextual, and systemic factors that shape user action (or inaction).

| Project | Focus | Key Outcome |
|---|---|---|
| 🎧 Music Discovery Gaps: Behavioral Signals Behind Popularity Failures | Behavioral data science · discovery systems | Built a residual-based popularity model (R² = 0.20) to analyze when recommendation predictions fail, revealing 20% unexpected outcomes, genre-level exposure bias, and underexposed “hidden gem” tracks. Delivered a full pipeline (Python modeling → report → Tableau dashboard) to diagnose discovery inefficiencies. |
| 🎬 Behavioral Recommender Systems: Understanding User Choice with MovieLens | Recommendation behavior | Modeled user–item interaction patterns and collaborative filtering signals to analyze how familiarity, preference history, and exposure shape recommendation outcomes and behavioral choice. |
| 🎪 Why Users Stopped: Behavioral Analysis of a University Festival Website | UX drop-off analysis | Identified points of hesitation and abandonment through real interaction logs, showing how unclear next-action cues disrupted behavioral continuation and task completion. |
| 🎧 How Audio Platforms Shape Listener Expectations | Human interaction | Explored how audio features & artist momentum influence perceived popularity through interactive behavioral analysis and signal interpretation. |
I’m interested in roles and research environments where understanding
why users fail to act matters more than maximizing model accuracy.
I’m particularly drawn to UX Research, Behavioral Data, HCI, and Human–AI Interaction problems that require explaining behavior — not just predicting outcomes.
