I was born in Aichi prefecture, and I entered Tohoku University. After I got a master’s degree at Tohoku University, I moved to Tokyo, and entered the Institute of Molecular and Cellular Biology, University of Tokyo. After getting PhD, I had worked as a postdoctoral researcher at Iwate University for five years. After that, I moved to Miyazaki due to my husband’s transfer. But fortunately, I was able to get a job here as a tenure-track (TT) assistant professor. After a five-years training period as a TT assistant professor, I was promoted to my current position (Miyazaki University, Associate Professor).

Recent Activities

Floral thermogenesis has been detected in dozens of plant species and has been proposed to play crucial roles in spreading odor to attract pollinators and protecting the inflorescences from freezing damage. Our long lasting interest is to fully characterize the molecular mechanism underlying thermogenesis in the reproductive organs of plants. Currently, we are investigating the mechanism by which plants increase cellular respiration and mitochondrial biogenesis for heat production. We also aim to explore the molecular mechanism linking temperature sensing and flowering. The primary goal of our research is to provide methodologies for controlling cellular respiration, temperature sensing, and flowering, allowing us to grow plants under abiotic stress conditions and improve crop production.

Message to Students

I graduated from Tohoku University. As a cross-appointment teacher, I am looking forward to seeing all the students of Tohoku University.
