Hello friend. I am not knowledgeable in this area, but I think it is probably easy to find a great topic by reading literature reviews.
Do you have a research study that interests you? It is not helpful for me to suggest a lot of random topics. Just find one article that is about something that really interests you. Read articles written by someone in your field, and find one that is very interesting to you. Read the literature review, and ask yourself what the next logical step might be in the work being done.
Your job is to "catch up" with what it being done in your field and make a great contribution. In order to contribute, you have to become an expert about how to use 1 or 2 styles of research that are often used in your field.
What types of research methods are often used in your field? Have you read any research articles recently?
