Journey Into Microbiology

Mondays with Professor Park

Mondays with Professor Park

As Professor Park describes in the following section, many of his early research experiences in microbiology were shaped in the dynamic laboratories of universities in both Korea and Japan, where his curiosity was nurtured and his passion for scientific discovery began to flourish.




“WHEN I FIRST GLIMPSED THE HUMAN MICROFLORA UNDER THE MICROSCOPE, I WAS UTTERLY OVERWHELMED.” 


The sample, taken from human breast milk and compared with formula milk for babies, left him shaken to his core. 


“The sight was as mysterious and breathtaking as gazing up at a vast night sky,” he said. 


“There were countless colors, sizes, and shapes, all swirling together in a hidden universe I had never fully imagined existed.”


It made him desperately want to understand how human breast milk and formula truly differ, especially in the ways they each shape an infant’s health and overall well-being.



When we consider the nature of passion, we see it everywhere: the poet’s passion lives in his poetry, the musician’s passion shapes each melody, and the actor’s passion speaks through every line performed. 


In the same way, his passion for microbiology did more than guide his career—it became the very heartbeat of his life. 


But it is his heart, after all, that truly recognizes and cherishes the beauty of this mysterious world.



“I SPENT EVERY SINGLE DAY IN MY PROFESSOR’S LABORATORY, WITHOUT HOLIDAYS OR BREAKS. I EVEN SLEPT THERE, LIVING ALMOST LIKE A MONK.”


Professor Park threw himself wholeheartedly into studying numerous papers on the microbiome and microflora. 


What amazed him most was realizing how underdeveloped bacterial research still was in the 1980s.


He explained, “Inside our bodies, especially in our gut, lives an astonishing variety of bacteria. Yet our understanding of their role in human biology remained very limited then.” 


Given the immense number of bacterial cells in our gut, it became clear to him that we couldn’t just overlook them or assume they didn’t matter.


“That sense of mystery made it irresistibly compelling to me,” he added, a spark in his eyes. “I fell in love with the hidden universe with my entire mind and body.”



Professor Park reveals his inner landscape with an exquisite balance of passion and self-discipline. 


Every expression of passion somehow projects something sacred—the living fire of love. 


It is no overstatement to say that passion is the crowning moment of love, for in passion the purpose of love is brought to completion. 


And yet, the unshakable discipline remains. Rock-solid discipline, I should say.



“DURING MY PHD, I HAD THE LIFE-CHANGING OPPORTUNITY TO STUDY IN JAPAN.”


Deeply respected in the field of microbiology, his supervisor there, Professor Kazuo Komagata, his charisma, kindness, and integrity left a lasting impression on him. 


“His example showed me what it means to unite scientific excellence with genuine humanity, and it continues to guide the way I think about research and mentorship,” he shared.



Also, he had the privilege of getting to know a British scientist, Professor Peter H. A. Sneath, a true pioneer in applying computing to microbiology, who later became his mentor.


Professor Sneath published an influential book on genomics titled “The Numerical Taxonomy of Microbiology” many years ago. 


In this work, he introduced numerical methods that went on to shape not only microbiology, but many other disciplines, including the social sciences. 


His ideas helped lay the foundations for technologies that now support artificial intelligence, human decision-making, and many other fields.


Professor Park shared, “I often look back with deep admiration and gratitude on how he was able to develop such profound ways of thinking and use them to solve complex scientific problems.” 


“His intellectual courage and creativity remind me that one person’s vision can transform entire fields and inspire future generations.” 


“Remembering his work encourages me to keep asking bold questions, to think rigorously, and to believe that thoughtful science can truly change the world.”



A human life is not just one story, but many. 


Each chapter, each life within a life, finds its wholeness when the passion that gives it energy is finally realized. 


“I MISSED KOREAN FOOD DEEPLY—ESPECIALLY GOCHUJANG AND KIMCHI. THESE FOOD ENERGIZED ME AND REMINDED ME OF HOME.”


Professor Park chose to work with DNA, RNA, and protein sequencing, stepping into the challenging world of microbiology and phylogenetic analytics during his PHD. 


The research demanded an enormous financial investment, relied on methods that were not yet widely understood, and required him to work with highly toxic and even radioactive chemicals.

His laboratory was small and had to be carefully sealed off to ensure safety. These are just some of the visible burdens he carried—without even touching on the inner struggles he faced throughout it all.


“There were times when I was exhausted from researching,” he said. In those moments, I turned to prayer and music to keep going.”



“IT WAS NOT EASY TO FIND A TUTOR OR SCIENTIST NEAR THE UNIVERSITY OF TOKYO WHO COULD GUIDE ME.” 


Despite facing this challenge, Professor Park did not give up. He reached out to another professor at Nagoya University, who opened his laboratory and guided him. 


During the 6 months he spent there, Professor Osawa patiently trained him, teaching him how to analyze DNA and RNA, interpret complex data, and carefully manipulate DNA and RNA through sequential techniques. 


“During that time, I practically lived in the laboratory,” he added. “I slept for many months in the chair, and the second episode of my ‘monk life’ quietly began.”



“I TURNED MY ATTENTION TO TRADITIONAL, WIDELY LOVED FERMENTED FOODSKIMCHI, THE REPRESENTATIVE KOREAN DISH INSTEAD OF ANIMALS OR HUMANS.” 


Many scientists in this field have dedicated their work to studying animals and humans, but Professor Park felt a quiet pull in another direction. 


He believed that probiotics could arise from a unique and distinctive source, one shaped by an entirely different microbiological and ecological background, and he followed that belief with conviction.


“Many people thought kimchi was not important—it was everywhere, very cheap, and taken for granted. I, however, saw something different: there was very limited research using modern, advanced biological approaches to study it,” he explained.



Surrounded by mocking voices and constant judgment of his beliefs, he refused to back down.


Through unwavering persistence, he rose to become a true pioneer in applying RNA sequencing to unlock the hidden world of microbial ecology and micro-ecological taxonomy in kimchi. 


At a time when this field was still taking shape, he carried his vision onto the global stage, presenting his revolutionary work at 3 international conferences in Manchester. 



Beyond what we call life, beneath what we can see and name, there is a vast activity that our limited minds cannot fully grasp.


Yet, as far as our human understanding can reach, we find nothing with a greater purpose or higher value in this world than passion. 



“I WAS SET TO CONTINUE MY STUDIES IN MARYLAND, BUT THEN THIS UNEXPECTED OFFER CAME ALONG AND TURNED MY PATH IN A WHOLE NEW, EXCITING DIRECTION.”


After his presentations, several scientists approached Professor Park, genuinely inspired by his research. 


He returned to Seoul and stood before researchers at the very institute he had dreamed of since high school: the Korea Advanced Institute of Science and Technology (KAIST), often called the Korean version of MIT.



“At that time, I was staying in Europe for two months, waiting for my dissertation to be finalized and still working on my data,” he recalled. 


“After my seminars, they wanted to recruit me and offered me a position. I was overjoyed—this was just 6 months before completing my PhD.”


In the end, he chose to return to Korea and join the institute he had once only imagined being part of, proving that long-held dreams can, with dedication and persistence, become reality.



FOOD FOR THOUGHT


Professor Park’s journey—from tiny isolated labs, sleepless nights, and homesickness for gochujang and kimchi, to pioneering research and a dream position—shows us how our paths can be. 


Ideals arise from the many diverse imaginations and experiences of people. They will never all be the same.


But the power to hold an ideal, to stay true to it, and give it life, belongs to the heart—the steadfast heart that holds reason within it and yet is greater than reason, just as the whole hand is greater than any single finger.


When we honor our passion, we honor the deepest purpose of our lives.
