A long time ago, in this very galaxy I was a Biology major. My undergrad focus was Ornithology and Ecology, but, the course load was balanced (molecular, biochemistry, calculus, physics, and the longest 4 letter word - organic chemistry). When i took genetics, something struck home, I was hooked. Grad school was focused on molecular biology and neuroscience. Several years in pharmaceutical r&d, now, after 10 years as a field application scientist in biotech, I’ve moved to scientific sales.
As you can see, I’m nowhere near the ornithologist I thought I would be, but, I’m still an avid birder. Keep your options open, try things, don’t ever think you can’t change your path. What you are learning now about being a scientist, the scientific method works for all problems, not just for the field or lab problems. Keep learning how to think and ask questions. Those skills will empower you in wherever you end up.
If you have questions, feel free to send me a PM. I’m happy to help any way I can.
