Ask HN: What should I study using MS/MS for my undergraduate research?

I should be graduating from college this year with a degree in Chemical Biology. As seniors, we undertake a research project of our choosing. I am working in the mass spectrometry lab; however, my professor does not have many suggestions as to what I could research in the field of Chemical Biology since he specializes in analytical chemistry.

What would you like to see done with this technology? I would like to do something involving my major, but I am open to other ideas. An idea I had was to see if it was possible to characterize plastics using Helium Plasma Ionization MS since it does not require sample preparation and could serve as a high throughput method at recycling facilities. Note that after graduation I plan to work at something along the lines of a rails developer so anything that could involve coding is also a plus.
