Founder of Chen AI Solutions LLC
As a Professor in the Computer Science department at West Chester University of Pennsylvania, my current research interests focus primarily on integrating artificial intelligence (AI) with educational technologies to enhance personalized learning experiences and optimize instructional methodologies. My recent work on RAG-based LLM alignment for classroom use received the Best Paper Award at IEEE TALE 2025. Additionally, I am actively exploring novel approaches that combine voice transmission technologies with advanced AI models to improve speech-based human-computer interactions and communication systems.
Previously, my research has extensively covered innovative solutions in mobile sensing and smartphone-enabled crowdsourcing technologies, aiming at building cost-effective and scalable information infrastructures. My scholarly contributions have appeared in highly-regarded journals and conferences such as ACM SenSys, IEEE ICDCS, IEEE MASS, IEEE Transactions on Mobile Computing (TMC), and IEEE IoT Journal. Notably, my paper on human voice detection technologies was awarded the Best Student Paper Award at the IEEE ICDCS conference.
I am an IEEE Senior Member and an active member of ACM.
