A biology degree - great. What, go be a "biologist?"
Right now, the math is simple: there are a lot of schools out there in forensics, but a shortage of qualified forensics experts to do the work. And there are few fields you can get into like forensic science with the opportunity to do engaging, plentiful work; to get up each morning and not know what kind of crime scene you will be working, or what kind of evidence will come into your lab. And when you go to bed at night, you'll sleep like a baby knowing that what you're doing has a direct impact on people's lives.
Enough jabbering already.
I've tried to make it dead-simple. Use the links we've included here to find where you live and look at the programs that are near you. When you're done with that, start thinking about the different fields of forensics you might be interested in. But even if you're still not sure, take a deep breath. Most forensic schools out there will give you broad survey courses in crime scene investigation, arson, drug chemistry, DNA, ballistics, hair and fiber analysis, criminal profiling, and on and on. So you'll have enough understanding under your belt to make an informed decision. (And if you're like us, you still won't know which one you like best, so you end up doing a few.)
