Dr. Yu employs a hands-on teaching approach that uses the tools that he develops and uses in his research. He has a diverse teaching scope and have contributed greatly at all levels of curriculum both for EHS graduate program and Interdisciplinary Toxicology Program.

Research Interests

Dr. Yu’s laboratory research is developing advanced tools to measures, models, and manipulates signaling activities at the single-cell (Micro) or population (Marco) levels to understand Dynamic Cellular Information Processing, and to explore the relationship between environmental exposures and human diseases. The ultimate goal is to improve public health by performing state of the art research that develops the scientific basis of methods used in risk assessment. We are currently developing in vitro three-dimensional cell culture models for improved methods to evaluate and predict toxicity, and discover novel Omics’ biomarkers.
