Welcome to the
Bioengineering Materials Lab (BML)
Department of Engineering, Hofstra University
Since Sept. 2014


We are developing polymer constructs with different mechanical, chemical, and biological properties in the form of thin films, gels, sponges, scaffolds, and meshes for tissue engineering and regenerative medicine applications.
Some of the materials’ desired physical properties include:
