Hi, I'm Dahana 👋

Computer Science student at Kean University, graduating May 2026. I work on data science, AI/ML, and full-stack web projects — including NSF-funded research on student success in CS.

🔬 Research

Cougar Pathway to Success — NSF Awards #1928452, #2129795, #2345334 + Sloan Foundation
Longitudinal analysis of 3,191 student records linking co-curricular engagement to professional outcomes. Built regression models (R²=0.53) and segmented 6 engagement tiers showing offer rates rising from 2% to 41.6% at 7+ activities. Co-authoring paper for ACM journal.

Equity in Software — NSF #2345334
Supported curriculum development and student data collection for broadening participation in CS.
