David Youssef-Undergraduate Research

For my research project, I tested the effect of a glaucoma drug, Latanoprost, on the collagen content of corneas in order to access the change in biomechanical properties of the cornea. This involved culturing corneas in one of two mediums, a control without the drug and a treatment medium with the drug. The corneas were cultured for 24 hours. After culture, the cornea samples were uniformly cut, homogenized, and put through a series of reactions to produce a mixture whose color reflected the concentration of collagen. After putting the samples through the spectrometer, the relative amounts of collagen were determined for the two treatment groups.

My data in this project matched my hypothesis that the treated corneas would have less collagen than the untreated corneas. However, this result is not statistically significant, so nothing can be concluded about the effect of the drug on corneal collagen content. With this conclusion, I learned a lot about how hard it is to conduct research. One may believe that they have considered all of the possibilities and factors in an experiment, but find that there was something they missed. Going into this project, I thought the ideas and concepts involved were interesting but not as much as other things I have learned about. As I would troubleshoot through the problems I encountered, I found it harder to stay motivated to do so because I wasn’t in love with what I was doing. I learned that it is really difficult to conduct a good research study if you are not completely invested because it needs a person’s all in order to succeed.

As I said in the previous response, I found out that I wasn’t as interested in ocular mechanics as I had thought. This doesn’t mean it’s a bad field to get into, it just means that I need to work in a field that I find more interesting in order to be happier and succeed. I have already made changes in order to do so. I have always known I was interested in neuroscience and how it can be augmented and treated using engineering but wasn’t aware that there was a laboratory on campus that did so until I was completing this project. After completing it, I told my principal investigator of the ocular mechanics lab that I was planning on moving on and she was very understanding. I contacted the professor of the neuroscience laboratory and he accepted me into his lab. In a broader sense, this project affected how I view my trajectory. I learned that I need to be having relevant experiences in order to be more successful and work in the field I hope to work in in the future. I also learned what motivates me and that I am most successful when I am working on these things.
