    I've been mainly working on string theory and related topics in quantum field theory and gravity. String theory is the most promising framework that contains quantum gravity: It solves the problem of short distant divergences which appear when quantizing general relativity perturbatively; It has also successfully provided microscopic description of Bekenstein-Hawking entropy of black holes. String theory is a rather simple extension of quantum theory based on particles to that based on strings, yet its consequences are amazingly rich and diverse: Unification of all the forces and particles, amazing relation between gauge theory and gravity, etc. etc. String theory also provides a framework to describe why our world is like we observe, e.g. why particle interactions are described by the standard model at low energy. This is because in string theory all the parameters in low energy field theory are in principle determined by solving string theory, though practically this is a very difficult problem and lot of efforts are currently payed to get closer to the solution. It should be noted that formulation of string theory itself is not yet complete at present: Most results have been obtained in first quantized formalism or by low energy effective field theory, due to technical complications in the second quantized formalism of string theory currently known. Considering string duality which relates different kinds of string theory, it is quite likely that we need to find a new formulation of string theory which go beyond the usual second quantization. There are many things we should understand better. If you are a local student who is interested in working in this field, you can directly visit my office for more detail. You can also have a look at ``For Students" below. In the meanwhile, some of you may be interested in the relation of the following subjects to string theory:
     Recently I am also interested in cosmology, in particular cosmic inflation. I prepared a litereture guide for those who are also interested.
