Ki-Jun Yoon, Ph.D.

Principal Investigator

As a first-year graduate student, I was strongly captivated by the beauty of the developing brain in the fetus. Neural stem cells are the core units to generate various regions of the brain and to regenerate the injured adult brain. I would like to pursue my academic journey with characteristics of such stem cells, which are flexible, open to any fate, and kindly helping damaged ones.  


Ajeet Kumar, Ph.D.

Postdoctoral Researcher

I received Ph.D. in August 2018 from Chungnam National University. In my graduate research, I studied the transcriptomic analysis of dopaminergic neurogenesis in zebrafish embryos. My long-term interests are neurodevelopmental biology, neural stem cell, and big-data-driven biology. In YOON LAB, I am focusing on the fate specification of neural stem cells modulated by post-transcriptional RNA-level regulation. Outside the Lab, I enjoy Hiking, Cooking, and listening Music.

Ph.D. Student

I think Biology is interesting because it is so relevant to our life. Especially, development includes the diverse mechanisms through which plenty of lives are born, live, and die. I was fascinated by this story, so I decided to study this field. The last destination of this story would be gene regulation. It is regulated by several steps through chemical modifications on DNA, RNA, and proteins. Among those steps, chemical modifications on RNA are in limelight recently. Therefore, I aim to figure out the epitranscriptomic regulations of development and physiology of life by investigating causal interactions between RNA modifications such as m6A and its related proteins.

How can we understand our brain? In fact, there are so many ways to answer this question. Someone may use physiological knowledge for this, but another person may use molecular biological knowledge. Actually, I want to explore this amazing brain world in human with the “molecular” aspect, including DNA, RNA and their unique modifications, and finally to know how it affects the developmental stages. :) 

Jihoon Moon

Ph.D. Student

I'm interested in brain development. To understand characteristics of brain development and its physiology, I want to develop novel technologies to generate brain organoids. In our lab, my goal is to know how RNA modification plays a role in the brain development and to model brain diseases with organoid.

Hoewon Park

Undergrad student

Hi. I'm HoeWon Park, undergraduate in KAIST. My major is currently biology and I want to study the relationship between Fetal development and RNA modifications, especially. For me, Yoon LAB is the best place to study and research about it. In the future, I hope to further broaden my knowledge in the area of human brain development. Watch me!

Bonsang Koo

Undergrad student

My name is Bonsang Koo. Currently, I'm on URP program to develope live-imaging sensor for m6A RNA modification. My main interest is development biology, especially neuro- and angio-genesis. Hope to push foward myself in Yoon LAB

Baekgyu Choi

Undergrad student

Hello, my name is Baekgyu, Choi. I’m senior in department of biological science in Kaist. Right now i’m doing individual study in Yoon LAB, since it has been very curious for me that m6A modification on RNA can influence on RNA halflife and consequently changes developmental states significantly in cells. Although I haven’t found specific research topic or interesting hypothesis yet, I’d like to keep studying on RNA modification further, thereby expanding our knowledge about this field much wider and deeper. Any interesting or unique hypothesis is always welcome!:)

Isaak Kim

Undergrad student

Hello, my name is Isaak Kim (김이삭). I'm undergraduate student in department of Biological Science, KAIST. Though it is first time for me to do individual study, I'm learning many things from professor Yoon, researchers, and other students. Because I'm interested in development and stem cell, Yoon lab is the best place  to learn and experience this field. I would keep investigate and hope to find some interesting topics to study further.
