Ray Liu, PhD, is the Head of Statistical Innovation and Consultation at Takeda Pharmaceutical Company. Dr. Liu received his BS and MA degrees from the National Taiwan University, Taiwan and his PhD from Columbia University, USA. He currently oversees the development of novel methodologies and provides statistical consultation and project support to various functional areas in pharmaceutical R&D, including Discovery, CMC, Translational Research, and Outcome Research. Dr. Liu was the conference chair of the 38th and 39th Midwest Biopharmaceutical Statistics Workshop. He is the author of more than 30 statistical and scientific articles and book chapters, editor of the Springer book “Statistical Applications from Clinical Trials and Personalized Medicine to Finance and Business Analytics”, frequent conference speaker on Big Data and the member of the ASA, PSTC Stats working group, IQ consortium, and NCBLF.   Yi Tsong, PhD, is the Division Director of Biometrics at the Food and Drug Administration (FDA). He specializes in post-marketing risk assessment, drug manufacturing process control and quality assurance, active control non-inferiority/equivalence tests, adaptive design, bioequivalence and analytical biosimilarity, and QTc trials, and has published more than 90 articles in these areas. Dr. Tsong received his PhD in Statistics from the University of North Carolina at Chapel Hill, USA and did his post-doctoral training in cardiovascular prevention and biostatistics at Northwestern University Medical School, USA. He has served as the Treasurer, Board Director, and President of the International Chinese Statistical Association and currently serves as Associate Editor of Statistics in Medicine, the Journal of Biopharmaceutical Statistics,and Pharmaceutical Statistics.
