I'm a particle physicist, currently working on Higgs physics at the International Linear Collider (ILC) and TPC R&D at the ILD which is one of the two detectors at ILC.

Topics I'm now interested in:

Probe the Higgs self-coupling
Determine the Higgs total width
Higgs couplings and global fit
Higgs CP and anomalous couplings
Effective Field Theory
Color-singlet jet clustering
Matrix Element Method
Flavor tagging algorithm
TPC test beam data analysis
TPC gating device R&D
