SKILLS
ABOUT PO-HSU ALLEN CHEN
I am a Research Statistician and Data Scientist whose work mainly focus on extracting useful information and structures from large, high-dimensional datasets. Since joining Battelle in August of 2016, I have utilized my skills in statistical modeling and programming to successfully analyze large complex high dimensional data in fields such as health care, biomedical research, and environmental dilution. At OSU, my PhD work focused on developing a new sequential design optimization algorithm using calibrated computer simulators. In addition, I have developed a framework using calibrated predictors that can help injection molding manufacturers to identify the processing conditions that optimize processes with several conflicting performance measures.
