Research Areas of Interest / Current Activities

 

Research areas: Synthetic inorganic chemistry, bio-inorganic chemistry, catalysis

 

Prof. Islam’s interests are focused on synthesis, characterization and catalytic as well as biomimetic / bio-relevant properties of transition metal compounds, including metal anchored functional polymers. One of the major activities of her group is the development of polymer supported transition metal catalysts for organic transformations under ecologically acceptable reaction conditions. Her group is also involved in the design and synthesis of water soluble macromolecular metal complexes and their applications as enzyme inhibitor.
