I’m a CIFAR AI Safety Postdoctoral Fellow at Quebec AI Institute (Mila), working under the supervision of Dr. Foutse Khomh, with Dr. Lei Ma and Dr. Randy Goebel as co-supervisors.

I obtained my Ph.D. from the University of Alberta in 2025 under the supervision of Dr. Lei Ma. Before that, I earned a B.S. in Computer Science from the University of Minnesota, Twin Cities.

My research focuses on the quality assurance of LLM-based systems, emphasizing testing, analysis, and behavioral monitoring. I’m particularly interested in the trustworthiness of large language models, robust AI system design, and HCI-driven approaches to AI system development. I’ve also had the pleasure of collaborating with Dr. Tianyi Zhang on SE & HCI related topics.

I’m always open to discussing new research ideas, collaborations, and opportunities in the field of software engineering and AI. Feel free to reach out via email or connect with me on LinkedIn.
