Achieving the Computer Forensics Dream

Hello folks, i am a Nigerian and got to know about forensics in 2010. i am currently studying chemistry but feel a deep passion for computer forensics and would want to help do my bit to make the world a better place through it. i want to know the necessary steps to take as forensics is not a thriving issue in Nigeria. Computer forensics for me is catching the tech bad guys. this is what i would want to help do. Would need knowledge, guidance and advise on this.
