Bioplastics, Biopolymers and Renewable Materials Research

Research Interests

Carbohydrate material is more plentiful in the biosphere than all other organic matter combined, and polysaccharides like starch, cellulose, chitin, agar, carrageenan,and pectin are gaining attention as renewable feedstocks for biodegradable plastics materials. Our research is directed at characterizing the interactions between starch and lignin in starch-kraft lignin-glycerol thermoplastic blends. Starch and lignin are two abundant agricultural feedstocks that could provide a large sustainable source of biodegradable plastics materials, but such applications require improving their materials performance through a better understanding of their interactions. We hypothesize that the chemical and physical properties of the components can be manipulated in order to optimize starch-lignin compatibilization, leading to applications such as biodegradable plastic film and foam for packaging and other applications.

Stereo view of agarose in a possible double helix conformation showing its lipophilic surface and the bound water in the double helix channel.


   1.1Mb and 0.5Mb respectively

The movies above are of a short interval in the dynamics run of the bound water in the core of a possible double helix conformation of agarose.


   1.6Mb and 180Kb respectively

 The movies above depict 50 picoseconds of a 1 nanosecond dynamics run on Methyl 3,6-anhydro-alpha-D-galactopyranoside. This simulation, showing the molecular rigidity around the X-ray structure, is one method in which crystal-solution structural equivalence can be observed.
