My lab has made significant progress in both areas in the past 5 years. We plan to build upon these accomplishments and apply our findings to translational research in cancer chemotherapy. I continue to serve as the course director of Advanced Molecular Biology (BIOC631). In this course I aim to teach students the latest developments in molecular biology/biochemistry, and teach the course in a participatory manner so that the students learn to analyze research papers critically and with emphasis on proper controls and quantitative analysis of the data.
