...Assistant Prof. Tanga joined our lab

Asst. Prof. Naomi Tanga joined our lab.

Hi all, my name is Naomi Tanga.
I joined for Nara Institute of Science and Technology on December 1st of this year. I studied at Nara Women's University Secondary School and Nara Women's University Faculty of Science.
The doctoral program is the National Institute for Basic Biology / Graduate University for Advanced Studies in Aichi. There, I have studied about cell signaling systems underlying brain functions and got my Ph.D..
After Ph.D., I joined a bio-startup company, and developed the human iPS cell-derived product that becomes the first commercial product for the company last year. Here, I would like to produce new innovative techniques for biological or agliculture fields by using the latest laser technology, with Professor Hosokawa and other lab members.
Thank you for your cooperation.
