My research areas primarily focus on the detection techniques and instrumenation in the experimental particle physics, including  

• Highly granular calorimeters with ultra-fine 3D positioning and fast timing;

• Semiconductor detectors: photo-sensors (e.g. silicon photomultipliers), large-area silicon sensors, etc.;

• Scintillator-based detectors: both inorganic scintillator (crystals) and plastic scintillator.

Major activities currently focus on the development of highly granular calorimetry, including 

• Design and optimisation studies on a finely segmented crystal electromagnetic calorimeter;

• Construction of a dedicated silicon lab and infrastructure, characterisations and mass assembly of 8-inch silicon modules for the CMS endcap calorimeter Phase-2 upgrade project (HGCAL);

• Development of a scintillator-tungsten sampling electromagnetic calorimeter prototype for future lepton colliders;

• Development of a scintillator-steel sampling hadronic calorimeter prototype for future lepton colliders;

• Joint efforts within the CALICE collaboration on the front-end electronics for SiPM readout and common beam tests.
