- Adviser: Dr. Shin-ichiro Kidou. My subcellular localization analysis and protein-protein interaction analysis have revealed that a novel grass protein is localized on Golgi apparatus membrane and is involved in synthesis of grass unique cell wall polysaccharide. This study was funded by funded by the 21st Century Center of Excellence Program - Establishment of Thermobiosystem Research Program from the Japan Society for the Promotion of Science (JSPS).
Graduate Research Associate
- Cryobiofrontier Research Center (CRC), Iwate University
- 2003 – 2008 Morioka, Iwate, Japan
- Adviser: Dr. Shin-ichiro Kidou. I developed new molecular biology technique, namely “Virus-Induced Gene Silencing (VIGS)” applied to cell-wall-related genes in cereal crops. This study was funded by a grant-in-aid from Iwate University, Japan.
Visiting Research Scholar
- Yale University
- 2007 – 2007 New Haven, CT, USA
- Adviser: Dr. Timothy Nelson. I performed a study entitled -“Unraveling the gene network involved in the barley seed development by LCM (Laser-captured Microdissection)") with Professor Timothy Nelson at department of Molecular, Cellular and Developmental Biology of Yale University This study was funded by a Young Overseas Joint Research Fellowship granted by the Japanese Society of Plant Physiologists (JSPP).
Undergraduate Research Assistant
- Iwate University
- 2001 – 2003 Morioka, Iwate, Japan
- Advisers: Dr. Masao Miyazaki and Dr.Hideharu Taira. I performed expression analysis and peptidase activity assay of a major urinary protein of the domestic cat which regulates the production of Felinine, a putative pheromone precursor. This study was funded by a grant-in-aid from Iwate University, Japan.
