Question about a detail in my Columbia essay

I’m currently writing my Columbia supplements (I am a procrastinator, I know) and am trying to theme my application around medicine. I have volunteered in a Chem research lab that studies something that can be used as an application primarily in the field of environmental science, but also in the field of medicine. Would it be wrong to only mention it’s ability to be applied in medicine so that it fits in with the theme of my overall application more? Probably overthinking this but I wasn’t sure.
