Research Interests
Dr. Shih has been teaching, doing research and participating in clinical research, especially in clinical trials, since 1983. He continues to read, write, and provide consultations in all aspects of design issues and analytical methods in improving efficiency for clinical research. For example, the common problem of missing data is one area that affects almost all clinical studies. The balance between clinical practice and scientific experiment is the key consideration and source of controversy in clinical trials. He devoted a textbook (2015), based on his research and experience, to teach students as they are the next generation to develop new methods for improving public health through evidence-based clinical research with statistical skills.   

Research Highlights

Presented the first paper (1989) at the Society for Clinical Trials that opened a new field of research and coined the term "sample size re-estimation" in clinical trials. This new field was then joined by others and rapidly developed into all kinds of "adaptive designs" that reshaped the future of clinical trials. Published the first paper (2001) in calling a new paradigm using consistency criteria for drug registration in Asian regional countries. This field of research was adopted by the International Harmonization Conference (ICH) for bridging studies, which then became the new guidance (ICH E-17) for Multiregional clinical trials (MRCT) for global drug development
