In general I feel pretty good about my application. I think I am in a strong position, as I have spent an "off year" just doing research, yet remaining in the undergrad category for the application. While I feel my personal statement could have benefited from a longer track record of commitment to my field, I think my research statement was extremely strong. One thing that concerns me is that the proposed research is quite interdisciplinary, combining elements of chemical engineering, bioengineering, and the life sciences. I am worried that I will get reviewers who are biased against the research because it incorporates other disciplines.
