Expertise

Research
Mechanochemistry. Direct-space methods to solve organic crystal structures from X-ray powder diffraction.

Research Interests

My research interests are: (1) The study of the kinetics of mechanochemical reactions toward the elucidation of their chemical mechanisms. (2) The mechanochemical synthesis of binary and ternary organic co-crystals with potential ferroelectric properties, and their solid-state characterization using single crystal and powder X-ray diffraction methods and other solid-state techniques. (3) To apply and advance direct-space methods to solve molecular crystal structures from X-ray powder diffraction data.
