I focuse on development of nanoporous materials and on understanding how the material formation process correlates with the materials characteristics. The materials are used in applications such as drug delivery, sensing, and catalysis.

The materials I work with have pores that are 2–50 nanometers large. The porosity makes the materials suitable for carrying drugs or other molecules. 

My research interests involve development of nanoporous materials and understanding how the material formation process correlates with the materials characteristics. The materials I work with have pores that are 2–50 nm large, which provides a large specific surface area, ~500–1000 m²/g.

The materials are synthesized using a sol-gel process, and I use in situ techniques to study how the materials are formed. This provides understanding of how synthesis parameters affect the characteristics of the final materials.

I have a large interest in designing materials for various applications, such as drug delivery, sensing, and catalysis. I explore how we can optimize the materials performance in each application by alterations of their composition, pore structure, and morphology.
