I just completed my masters degree in Information Technology and I want to proceed to PHD but I don’t have any idea of what research to do.

I work as a solution support and research, I have great interest in data analysis. Have worked on various projects in application implementation of Electronic medical records in top hospitals in my country.
I work closely with stakeholders, users , product managers and development to build and support different applications.

I have been racking my brain on what research to dive into as I have no coding experience.

What research are available that doesn’t require programming. I need help, advice and suggestions
