Lab Members

At present time, I have two Ph.D. students, four master students and two undergraduate students. We have journal club and lab progress report every week. They are well trained not only in knowledge of Plant Virology and Molecular Biology but also in the experimental skills. I hope that students graduate from my laboratory will be welcomed by other persons and find a wonderful job in university or research institute because of their superior training and learning in here. I am proud of them and hope this good tradition will be continuous. Our laboratory has plenty of research facilities, including high-speed centrifuge, ultracentrifuge, nucleic acid and protein purification equipments, PCR-thermal cycler, gel electrophoresis apparatus, ELISA washer and reader, fluorescent spectrophotometer, electroporator, automatic sequencer, fluorescence microscope with CCD camera system, etc. This is really a nice place to do research.
