Ph.D. in AI Engineering · Adjunct Professor in the Department of AI Software · CEO of Happy AI

Hello.
I am Lee JinKyu, and I research, develop, and teach AI, focusing on natural language processing (NLP) and large language models (LLMs).

I earned a Ph.D. in Engineering specializing in Artificial Intelligence and have conducted research primarily in natural language processing and LLMs.

I am currently an adjunct professor in the Department of AI Software, teaching AI-related courses such as natural language processing and computer vision, and I run HappyAI, a generative AI company.

After working as a natural language processing and big data analysis researcher at a government-funded research institute, and then as a developer at an AI-specialized company, I currently carry out AI projects and training for businesses and public institutions.

At various companies and institutions, including Samsung SDS, KT, Hyundai Wia, and the Seoul Digital Foundation, I have conducted training and projects related to generative AI, LLMs, RAG, AI agents, and fine-tuning.

Additionally, I have conducted natural language processing and text mining research on various types of unstructured data, including documents, surveys, reviews, news media, policy, and academic data, and have experience with research and analysis projects across fields such as healthcare, policy, the environment, law, economics, and education.

What I Consider Most Important in My Lectures

AI technology is changing rapidly, but if you understand the core principles, you can learn new technologies much faster.

In the lectures, rather than simply following features or code,

“what it is → why it is needed → how it works → where it is used in practice”

I consider it most important to explain things clearly so that you can understand them.

Rather than explaining complex AI technologies in a difficult way,
I will explain them so that even beginners can understand the overall structure and apply them to real-world work and projects.
