About

Cosmin C. Dobrescu is a researcher at the forefront of human-robot interaction and conversational AI, with a focus on socially assistive technologies. His work bridges affective computing and large language models (LLMs) to create more natural, empathetic interactions between humans and machines. Dobrescu’s notable contribution includes the development of a social companion robot that incorporates affective proactive behavior to support community-dwelling older adults, a study that has garnered 7 citations for its innovative approach to eldercare. More recently, he has advanced the field of conversational agents by conducting a comparative analysis of generic versus fine-tuned GPT-3.5-turbo models within chatbot development platforms. This 2024 work, with 6 citations, demonstrates how fine-tuning can significantly enhance dialog flow design, offering practical insights for deploying LLMs in real-world systems. His research is characterized by a commitment to improving user experience through emotionally aware and contextually responsive AI, making his work highly relevant for students and researchers exploring the intersection of robotics, natural language processing, and human-centered design.
