I tent to not label myself as an AI researcher because meaning of AI varies across different people. To me, the term Artificial Intelligence means the common part that everyone can agree on.
It is very difficult to specify the areas of AI that I am particularly interested in. They interact with each other. For example, in robotics you need planning and in planning you need searching.
In general, I am interested in the following fields of/related to AI:
Some parts of AI are related to a programming paradigm known as declarative programming. For example, in knowledge representation and reasoning, the tools to represent knowledge are usually based on logic programming while the reasoning algorithms can be inspired by research in constraint programming. Unlike imperative programming (where users specify the algorithms to solve specific problems), the idea of declarative programming is very attractive:
The user states the problem, the computer solves it.

Hence, it is directly related to the motivation of AI that is to build a machine that can think.
I am interested in the solving techniques and applications of the following fields:
