You really should break down biology into something more specific about what you want. Biology is incredibly broad, covering everything from taxonomy to genetics to biochemistry. I'm in Chemical and Biomolecular Engineering, and I could probably speak with confidence on some areas, but not others. My strongest point would be biochemistry, but I can't see why SI would need most of my BCMB knowledge. But if you do, you're more than welcome to contact me. And since most people on here probably aren't as well versed in general biology, I'm willing to at least try to answer any questions in the broad field that you have.
