Department of Computer Science
University of Nevada, Las Vegas
I am a PhD Candidate and Graduate Assistant in the Department of Computer Science at the University of Nevada, Las Vegas (UNLV), working in the Software Evolution (EVOL) Lab under the supervision of Professor John Businge. I hold an MSc in Computer Science from Makerere University, Uganda (advised by Dr. Joyce Nakatumba-Nabende and Prof. Michel R.V. Chaudron) and a BSc in Computer Science from Gulu University, Uganda. My research lies at the intersection of Empirical Software Engineering and AI for Software Engineering, with publications in venues including ASE, SCAM, MSR, AIware (co-located with FSE), the Empirical Software Engineering (EMSE) journal, and SEDE. I serve the research community as a Junior PC member for MSR 2026, a PC member for ESEC/FSE 2026 (Ideas, Visions, and Reflections track), and a reviewer for Springer Nature Scientific Reports, Elsevier Data in Brief, and the Journal of Advances in Information Technology.

Patchtrack: a comprehensive analysis of chatgpt’s influence on pull request outcomes
Daniel Ogenrwot, John Businge
AIware 2026 — Benchmark & Dataset Track (co-located with FSE 2026) 2026
The rapid adoption of large language models (LLMs) like ChatGPT has introduced new dynamics in software development, particularly within pull request workflows. We analyze 338 pull requests from 255 GitHub repositories containing self-admitted ChatGPT usage, comprising 645 AI-generated snippets and 3,486 developer-authored patches.
