Yukihide Tomari, Ph.D.

The excitement of discovery is one of the greatest pleasures of science. The RNA field is still full of unknowns and we are fortunate to be able to enjoy tackling them. Our lab welcomes anybody who is interested in solving the complex puzzle of life together with us.


Hiro-oki Iwakawa, Ph.D.

Theme: understanding of the molecular mechanism of small RNA-mediated gene regulation.
Interests: delicious "Szechuan dish of noodles" without tahini and soup.

Technical Specialist

Natsuko Izumi, Ph.D.

I'm Natsuko Izumi. I study the biogenesis of piRNAs, germline-expressed small RNAs.

Research Associate

Masahiro Naganuma, Ph.D.

I'm interested in understanding molecular mechanisms of RNAs and RNA-binding proteins. My hobbies are playing futsal and fishing. My favorite phrase is "work hard, play hard."

Research Associate

Keisuke Shoji, Ph.D.

I study piRNAs, a class of small RNAs, using silkworms. I'm a foodie but can't eat spicy foods.

JSPS Postdoctoral Fellow

Kotaro Tsuboyama, Ph.D.

I have such a bad eyesight that I cannot walk outside without glasses, but I am very sensitive to light stimuli. My motto is "seeing is believing" and I am trying to find something interesting by microscopes. I am not very good at cooking, but I become stressful if I cannot eat what I cook at least once a day.

Ph.D. Student

Kenji Okomori

Born in Hokkaido, I now work here as a master's student. I study the mechanism of mRNA decay in early development using zebrafish. My dream is to become a scientist who can share the fun of science with children and students!! I like watching baseball games (sometimes football) and I am a big fan of Nippon Ham Fighters.

Ph.D. Student

Jie Yu

I’m Jie from Qingdao, China. My major was chemistry until I finished my master’s course. From now on, I’m going to explore the fantastic RNA world. At my leisure, I often watch animations, especially those in which the voice actor Daisuke Ono participates.

Ph.D. Student

Shirui Chen

I am Shirui Chen from China (please call me Sherry~). I was born in Changchun and after graduation from high school, I have been living in Shanghai. I am interested in the functional mechanism of small RNAs. In my spare time, I like to go for a walk and feel the unique culture in Japan. In addition, I like cats very much!

Ph.D. Student

Takumi Tomohiro

I study the molecular mechanism of miRNA-mediated translational repression, using in vitro translation system. I do experiments every day to find my own philosophy someday. My hobby is playing the guitar. I especially like Alternative Rock music.

Ph.D. Student

Fumikazu Shinohara

I am interested in understanding the siRNA working mechanism and applying it to application. My morning routine is to drink tomato juice and green vegetable juice. My favorite word is "It always seems impossible until it’s done." by Nelson Mandela.

Ph.D. Student

Wei Liu

I am from Guangzhou in China. Now I am studying the mechanism of RISC assembly in plant Argonaute proteins. I like reading detective stories in my leisure time. My favorite quote is “You see, but you do not observe. The distinction is clear.”

Ph.D. Student

Benny Chung

I am Benny from Hong Kong. Literatures from Tomari lab is what brought me here and I love the mechanisms of small ncRNAs and their loading partners, as everyone else here. I like electronic music, especially trance.

Ph.D. Student

Yuriki Sakurai

I am Yuriki Sakurai. I am studying the molecular mechanism of RNA silencing pathway in plants. One of my hobbies is watching Korean dramas, so I can read and speak Korean language a little. I have a weakness for sweets.

Master's Student

Andy Lam

Hi, I’m Andy from Vancouver, Canada. My hobbies include practicing kung fu, watching Netflix shows, anime and hockey. Currently, I’m studying the mechanisms of RISC in plants. Learning a new language, living in a vibrant new city, and studying such a dynamic field, I find myself learning so much every day!

Master's Student

Tatsuya Ishizuka

Hi, I’m Tatsuya. Currently my study is based on Hero proteins, a peculiar group of unstructured proteins. In my free time, I like to discover new ramen restaurants and watch sports.

Master's Student

Xiao Qi (Kazuki Uruhara)

I’m a foreign research student from Hunan, China and I love spicy food so much. I have been studying biology since high school and I think that solving the unknown questions in the world of life is attractive work. Now I’m interested in piRNA research. I also enjoy Japanese social culture, language, animation, music and so on, and hope I can do my best here.

Master's Student

Selena Setsu

It is fascinating how far human beings have figured out the way organisms work. Right now, I am seeking what I do not know, and continuing that way I hope to unveil mechanisms that no one yet knows. Eating foods from other countries is fun; it makes me feel as if I am traveling to these countries.

Lab Technician

Kaori Kiyokawa

I take care of zebrafish, fruit flies, cell culture etc. I'm a zookeeper in the Tomari lab.

Administrative Assistant

Yukiko Koshiba

I would like to help young researchers to concentrate on their research.
