Aji Mathew



Prof. Mathew has 16 years of experience in the field of cellulose nanocrystals, cellulose nanofibers, chitin nanocrystals and their nanocomposites. Prof. Mathew has published over 100 peer–reviewed articles (H–Index 30) and has about 80 conference contributions, 16 book chapters, 7 edited books and several invited presentations to her credit. The research activities in her group focus on sustainable and green processes for the isolation of biobased nanoreinforcements and the development of processing routes for functional materials as biobased nanocomposites and hybrids.  The main application area include water purification membranes/ filters and biomedical implants- with focus on tailoring of functionalities as surface chemistry, surface specific interactions,  ion- exchange,  antifouling, cell interactions,  controlled release,  etc.  One main scientific goal  for the group is understanding  and explaining  the correlation between the processes, surface characteristics and morphologies of the nanoparticles,  material properties and  material performance.
