Research Summary:
Professor Becker's Laboratory for Functional Biomaterials seeks to develop new materials and methods which stimulate and direct specific cellular functions.  The multidisciplinary group works at the interface of chemistry, organic materials and medicine and focuses on developing chemical methods to tether peptides, proteins and growth factors to translationally-relevant materials. These materials include peptide and carbohydrate derivatized materials, which incorporate bio-functional species in a controlled manner, with the goal of influencing cell response.


We are focues in three key areas which motivate our work:

1) Developing chemical methods to control the placement of functional groups

Polymers
