There are 32 doctor supervisors and 34 graduate teachers in BRI. In the past 2 decades, we have trained 145 graduate students. Among these there are 49 doctors, 88 masters, and 8 post-doctors. We pay special attention on improving the teaching and scientific guiding ability of the supervisors. Students at BRI have not only been able to acquire solid basic knowledge and active creative thinking, but also develop fine qualities of realistic approach, truth seeking attitude, collaborative work and creative spirit.
