  • Photocatalysis
  • Microheterogenous solutions
  • Organic synthesis at interfaces

The research interests of the group focus on the development of novel synthetic methods, which utilize the energy of light to fuel chemical reactions. Our studies involve the use of aqueous, microheterogenous solutions as efficient photocatalytic systems of unique properties. In particular, we explore methods for converting stable and readily accessible starting materials through selective activation of strong chemical bonds.
