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 a 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 to Music.

Ph.D. Student

I think Biology is interesting because it is so relevant to our life. Especially, the development includes 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 brains? 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 humans 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 the 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 brain development and to model brain diseases with organoid.

Hyunsoo Jang

Ph.D. Student

Common neurological diseases can be traced back to the dysfunction of the molecular machinery underlying neuronal development. Thereby, it is essential to investigate the molecular and cellular mechanisms promoting brain development to provide therapeutic opportunities. I am intrigued by developmental neurobiology which enables me not only to understand the complexity of the brain but also to serve others. I hope my journey to scientific inquiries will have surprising applications in natural science and medicine.

Hoewon Park

Ph.D. Student

Hi. I'm HoeWon Park. Life is the most valuable and complicated, which bring me to study biology. My interest for the future is regeneration of human body. I think it can make the world more healthy and spectacle. Our laboratory is the most suitable place to research and live together with kind members. In the future, we will gonna make a great step in biological science!


Bonsang Koo

Ph.D. Student

My name is Bonsang Koo. Currently, I'm on the URP program to develop live-imaging sensor for m6A RNA modification. My main interest is development biology, especially neurogenesis and angiogenesis. I hope to push forward myself in Yoon LAB.
