Research Interests

Investigating the structure of the nucleon and the dynamical interaction between its partons, which is governed by the theory of QCD, such as

• Studying higher twist effects.
• Using W production to determine helicity dependent and independent sea quark structure.
• Nucleon spin dependent structure functions.

Developing Micro-Pattern Gas Detector (MPGD) technologies with a particular interest in micro-RWELL detectors.
 
Research and development of MPGD trackers for use at the electron-ion collider.
