Talk Abstract: 

Galaxy cluster is the most massive, gravitationally-bound structure in the Universe, and provides a good test-bed for the study of galaxy evolution in dense environment.

While, at local, it is well known that various properties of galaxies show a clear environmental dependence, it is still an open question when and how this environmental dependence was developed and shaped.

In this talk, I will present our recent results on the evolution of star-formation (SF) properties of high-redshift galaxies in clusters and in field, using the deep, multi-band photometric data of the UKIDSS/UDS.

Also, I will introduce the IMS (Infrared Medium-deep Survey) conducted by our team, and on-going efforts on the high-redshift galaxy cluster study.
