About Me
- My teaching philosophy centers on encouraging students to ask questions. Curiosity is the essence of science. I try to create an “open classroom,” a comfortable and engaging environment that promotes class participation and hands-on learning. I believe that a dynamic and open interaction between teacher and students facilitates the best method of learning.
- Including students in lectures encourages them to frequently ask questions. I also incorporate case studies and real-world applications of the material into all levels of my teaching.
Research Interests
- Using the model organism Drosophila melanogaster, I involve many undergraduate students in my research on how alternative splicing affects lipid metabolism in an effort to better understand gene regulation mechanisms related to obesity. I am also interested in the effect of diet and supplements on lifespan and fitness in both male and female fruit flies. Additionally, I collaborate on a project to identify regulatory genes involved in sexual dimorphism in the jumping stick Stiphra sp.
