I'm a biostatistician at Sanofi. The best part of my job is working with talented colleagues and applying statistics to clinical trials for drug development. My advisor, Dr. 许ming 他, not only guided me in dissertation, but also helped me to gain precious experience by working as a statistical consultant at the department of statistics, a research assistant for data analyses in deglutition and respiration studies, and a 苏mmer Associate at Pfizer. The statistical courses including the theoretical ones and the practical ones offered by great teachers laid the solid foundation for my career. The friendly and talented graduate students, faculty and staff at the department of Statistics made me to feel like in a warm family.
