I am very keen to do some research in the field of DIP and publish a paper on it. I am totally confused on how to start and where to start learning from. Kindly help me.
I'd recommend narrowing your focus as to what you want to research, and then search for firms that perform DIP; find out what existing literature may reveal as to what's been written, then find your niche in the body of knowledge to fill. I pray this helps!
