Sounds like you were data mining rather than testing a hypothesis.
Your current lab is a research project. I suggest finding another one if the PI is so unpleasant. It's not worth it.
Would this current lab experience be viewed akin to a "lab tech" doing scut work, or a little more favorably?
Shirafune- I think I can articulate it well to make it sound meaningful: the documentation is certainly important because they need to know which injection sites are of good quality and confirm that they're in the correct location of the brain. This assures that the correct mice are selected for further study.
GrapesofRath- Interesting you think last summers project was more meaningful.
BUMP for more opinions on it all!
If I understand your role correctly, I don't think it is an ideal situation. I don't want to be mean, but it sounds like you're more or less just doing repetitive screening work. It certainly is an important part of validating other results in the study, but you ideally want involvement in the "other results." I encourage you to get into the grit of the rest of the study. Knowing the appropriate controls of a study is important, but the rest of the project is much more interesting and can illustrate a higher level of scientific thinking.
Okay. How about for MD only, are either of these experiences noteworthy to mention on my application?
Glad to here this, thanks.The second experience sounds like a standard pre-Med lab experience to me.
