We now have evidence that most of the matter in our universe is unknown particles about which we understand very little. These particles must have been created in the early universe through high energy collisions of the standard model particles. Starting from 2008, the Large Hadron Collider (LHC) at CERN will reproduce such high energy collisions so that we have a chance to see the evidence of dark matter（DM）production in our universe.
My current research focuses on the discovery and reconstruction of DM at LHC. The direct production of such particles is very difficult to see, but in many models DM is produced with a set of new particles and production of DM can be observed as the missing energy. We may even be able to learn deeper reasons why these particles are needed by understanding such events carefully.
Half of my research activity involves collaboration with other experimentalists.The LHC is a big project which needs the coherent work of theorists and experimentalists,and I hope IPMU can play a key role in increasing communication between the two.
