Tomson is a student in the Graduate School of Medical Sciences. He obtained PharmD and MSc (Biomedical Sciences) before working in a Biopharmaceutical company on chemical protein modification for 2 years. From 2021, he is a member of Sada's Lab studying microbial signals-stem cell dynamics.


Thisakorn Dumrongphuttidecha

Ph.D. student

(Rajamangal University of Technology Thanyaburi Scholarship)

Hi! I am from Thailand. I am interested in skin regeneration and aging. It is a wonderful opportunity to be a member of  Dr. Sada’s lab. I believe that I will get extensive medical knowledge and advanced research skills from IRCMS, Kumamoto University under the guidance of Dr. Sada and enjoy life in Kumamoto.


Trisha Biswas Shanta

Ph.D. student (MEXT)

Hello!  I am Trisha from Bangladesh. I have interests in the epigenetics, stem cells, skin renewal and aging process. Currently, I am working with Dr. Aiko Sada. I am so glad to have a great team here. I also hope that I will improve my understanding of this field and can utilize my knowledge for future skin research. Though It is my new journey in the field of skin regeneration, I hope this new journey will be the best journey in my life. I like to spend leisure time by singing, reading story books and travelling.

Phung Hung Manh

Ph.D. student (MEXT)

Hi! I am a Vietnamese PhD student. I am curious about the mechanism of aging in the skin and the way the skin responds to various intrinsic and extrinsic stresses during the aging process. And now I am working with Dr. Sada to clarify the mechanism of epidermal stem cell aging and tissue regeneration. I hope that my studies will contribute to elucidating further skin aging and may be applied to provide a new therapeutic strategy to prevent skin aging and contribute to healthy longevity.


Hinata Date

Ph.D. student

Hi, I am Date Hinata. I joined Sada Laboratory after obtaining my master's degree from the Graduate School of Science and Technology, Kumamoto University. I am particularly interested in aging and regenerative medicine, and would like to understand how and why our bodies change as we age. Through my research in the Sada Laboratory, I hope to deepen my understanding of the aging system, which still remains a mystery.


Ikuto Nishikawa

Ph.D. student

Hi, I received my master's degree from Kumamoto University and then started a PhD at Kyushu University. I am interested in skin science and regenerative medicine, so join Sada lab. I am from Yokohama in Kanagawa and graduated from university of Rikkyo, faculty of science in Tokyo. And there, I learned cell biology. My hobby is playing basketball and eating delicious food. I will do my best to be able to make a great discovery!


Wanqing Li

Ph.D. student (The Sasakawa Medical Fellowship)

Hello! My name is Wanqing Li and I come from Beijing, China. I have completed a Master's degree at Beijing University of Chinese Medicine. I am honored to join Dr. Sada's team in exploring the fields of skin regeneration and aging. I am particularly interested in skin stem cells because they hold the promise of addressing the aging-related concerns that affect us all. I hope to contribute to the development of innovative approaches to promote skin regeneration and combat the effects of aging.

Aiko Sada


Aiko Sada received a Ph.D. in 2011 from the Graduate University for Advanced Studies, Japan. Soon after her graduation, she joined Dr. Tudorita Tumbar’s laboratory at Cornell University, as a postdoctoral fellow, where she worked on identification and characterization of epidermal stem cells. In 2016, she started as a tenure-track Assistant professor at University of Tsukuba. In 2019, she started her own laboratory at IRCMS, Kumamoto University. In 2023, she moved to Kyushu University and was promoted to professor.


Makoto Takeo
Associate Professor

After Makoto Takeo received Ph.D in 2008 from the Hokkaido University for molecular study on earthworm regeneration, he jointed Dr. Mayumi Ito’s lab at New York University as postdoctoral fellow and worked on regeneration of hair follicle and digit regeneration in adult mouse. In 2016, he returned to Japan and worked in Dr. Takashi Tsuji’s lab as senior scientist and keep investigating using mouse hair follicle as a model. In 2024, he jointed Dr. Aiko Sada’s lab as an Associate Professor.


Mizuho Ishikawa

Assistant Professor

Hi, I am Mizuho Ishikawa. I graduated from Tottori University and now I joined Dr. Sada's lab. I am interested in skin stem cells, aging, and vasculature. Through doing research on stem cells and aging in this lab, I hope to solve a part of the mystery of life phenomena as much as possible.
