Hello, Dr. Min. Could you please start by introducing yourself?

Hello, I am Gihyeon Min and I earned my Ph.D. in 2014 from the School of Electrical Engineering and Computer Science at Gwangju Institute of Science and Technology (GIST). Currently, I work as a researcher in the Artificial Intelligence Convergence Laboratory at the Electronics and Telecommunications Research Institute (ETRI).

During my doctoral studies, I focused on digital holographic imaging technology, which reconstructs 3D images from 2D images using physical computation. Additionally, I researched methods to restore defocused 2D images to a focused state. I also concentrated on developing Optical Coherence Tomography (OCT) technology, which enables non-invasive internal biological observation using light.

At ETRI, my current research involves developing AI models and optimizing them for practical applications. My work emphasizes solving real-world problems and commercializing technology through the convergence of AI with various fields.

I heard you are currently conducting AI-related research, which is different from your original major.

My interest in AI stems from a deep curiosity and its immense potential. During my time studying optics, I had the opportunity to integrate AI into spectral imaging technologies, which sparked my enthusiasm for AI.

Later, I delved into AI-based research, focusing on developing technologies to diagnose skin cancer and skin diseases using image data. Notably, my team participated in the ISIC Challenge and achieved 8th place, an experience that greatly motivated me.

Through these diverse AI projects, my curiosity for research grew further, and I continue to explore new possibilities in the AI field to this day.

What inspired you to pursue a career as a researcher at the Artificial Intelligence Convergence Laboratory, Honam Research Headquarters?

During my graduate studies, I aspired to develop technologies that could be practically utilized. I was particularly drawn to government-funded research institutes (GRIs) because of their role in creating technologies for and supporting small and medium-sized enterprises (SMEs).

Initially, I developed technologies related to my major in another laboratory. However, I eventually transitioned to the Artificial Intelligence Convergence Laboratory after working on a project to support the translation of classical Chinese texts using AI. This opportunity allowed me to explore the intersection of AI with various fields, which I found incredibly rewarding.

Working at the Artificial Intelligence Convergence Laboratory has been fascinating, as I get to understand a wide range of fields and address real-world research topics. This process of identifying and solving problems is both fulfilling and enjoyable.

After earning a Ph.D., typical career paths include academia, industry, or government research institutes. Companies focus on commercialized research and technology development for immediate market application. Academia prioritizes fundamental and theoretical research. GRIs, on the other hand, operate in a middle ground, bridging fundamental research and commercialization. They develop pre-commercialization technologies and collaborate with SMEs to deliver tangible outcomes.

GRIs also offer opportunities to co-author papers with SMEs, enabling researchers to experience growth and achievement simultaneously. These factors led me to believe that GRIs were the ideal career choice for me.

Could you share a memorable experience from your research that brought you a sense of accomplishment?

Until last year, I led a project developing AI-based text recognition and translation technologies. The project aimed to create technologies and platforms that make translation easier for users, resulting in content derived from classical Chinese texts.

We successfully implemented the technology as kiosks in 12 locations nationwide, including the National Assembly Library, National Library of Korea, and Jeju Library, as part of a pre-commercialization trial. When users provided positive feedback, expressing gratitude for the technology, I felt a great sense of accomplishment.

One memorable case involved a user seeking to register an artifact as cultural heritage. The individual needed evidence and used our kiosk to translate classical Chinese texts, which helped secure the artifact’s registration in Gimcheon. Receiving their heartfelt thanks was incredibly rewarding.

Another user praised the translated output for being more natural and smoother than previous translations, highlighting its practical usability. These experiences affirmed that my research and developments were genuinely helping people.

How do you typically manage stress during your research process?

When stressed, I turn to hobbies for relief. For instance, I would play the piano and sing in the building's lobby to unwind. This simple pastime helped me recharge and refocus.

Stress often arises when projects hit roadblocks. During such times, I continuously ponder solutions and maintain a patient, persevering mindset.

I firmly believe that once I choose a path, I must see it through, regardless of difficulties. This principle applies to career choices as well, ensuring that I commit wholeheartedly to what I desire. The joy of overcoming challenges and achieving results is the greatest reward.

In summary, the fulfillment of completing a task and seeing results is what motivates me to overcome stress and continue my research journey.

What are your future goals?

While advancements in science and AI have improved our lives significantly, gaps still exist in society. Socially marginalized groups, environmental issues, and safety concerns remain unsolved challenges.

My goal is to develop technological solutions to address these problems. I aim to analyze these issues thoroughly and explore how technology can provide effective resolutions.

For example, tragedies such as the Itaewon crowd crush, apartment collapses, and air pollution highlight critical areas requiring solutions. I hope to develop technologies that prevent or resolve such problems, contributing to safer and more comfortable living environments.

Through continued research and development, I strive to create technologies that bring tangible changes to people’s lives and help reduce these societal blind spots.

Why did you choose GIST?

I was interested in developing medical devices, particularly those using lasers for non-invasive internal body imaging. Learning that GIST conducted such research motivated me to apply.

Additionally, GIST's full-tuition scholarships, dormitory accommodations, and research stipends allowed me to pursue my studies independently, without financial reliance on my parents.

GIST also provided opportunities to interact with globally renowned scholars through seminars, broadening my horizons. Furthermore, GIST facilitated international research and academic exchanges, such as collaborations with MIT. This combination of resources and opportunities made GIST an ideal choice, and I remain satisfied with that decision.

Do you have any advice for GIST students or graduate students?

The reason I study is "to give back." Pursuing knowledge solely for personal gain is akin to stagnant water that eventually decays. My goal, even after graduating and working at a government research institute, has been to responsibly lead projects, develop technologies, and contribute to their commercialization. The greatest reward comes when the technologies I develop provide real benefits to people.

It’s essential to define your purpose in studying and living. Don’t just study for success—embrace the mindset of "studying to give back." By maintaining this perspective, I have worked with dedication and enthusiasm, adhering to values such as:

1. Adopting a broad perspective: Analyze problems from multiple angles, take an interest in diverse fields, and develop problem-solving skills.

2. Maintaining a giving attitude: Achieving significant outcomes often requires collaboration. When your hard work extends beyond theoretical achievements and translates into practical applications that benefit others, it’s truly fulfilling.

With this approach, you can reduce selfishness, build meaningful relationships, and experience genuine accomplishment. I hope you become a researcher who learns, grows, and creates value for the benefit of all.
