Christopher Li

Christopher Li, PhD

Professor of Materials Science and Engineering

College of Engineering

Li is a professor in the Materials Science and Engineering Department and director of Drexel's Soft Materials Lab. His lab's research focuses on materials whose properties fall between solid crystals and fluids, such as polymers, gels, colloids, foams and liquid crystals. Li's group is able to engineer these soft materials for use in biomedical applications like drug treatment delivery, as well as for energy storage. 

His lab is also developing way to engineer nano crystals in ways that mimic natural structures, like bones and bone scaffolds. This research could lead to medical applications that help to enhance the healing of broken bones. Li has been recognized for his outstanding teaching and research by several national science and engineering groups including the National Science Foundation the National Academy of Engineering and the National Research Council.

    Pausing Nature's Crystal Symmetry to Advance Targeted Drug Therapy

    From snowflakes to quartz, nature’s crystalline structures form with a reliable, systemic symmetry. Researchers at Drexel University, who study the formation of crystalline materials, have shown that it’s now possible to control how crystals grow – including interrupting the symmetrical growth of flat crystals and inducing them to form hollow crystal spheres. The discovery is part of a broader design effort focused on the encapsulation of medicine for targeted drug treatments.

    Drexel's Polymer Pill Proves it Can Deliver

    Selecting the right packaging to get precious cargo from point A to point B can be a daunting task at the post office. For some time, scientists have wrestled with a similar set of questions when packaging medicine for delivery in the bloodstream: How much packing will keep it safe? Is it the right packing material? Is it too big? Is it too heavy? Researchers from Drexel University have developed a new type of container that seems to be the perfect fit for making the delivery.

    Drexel Materials Scientists Roll Out New Method For Making The Invisible Brushes That Repel Dirt

    Drexel researchers have reported on a new method for producing the polymer "nanobrush" coating that is used to prevent ships from corroding, glasses from smudging and artificial joint replacements from locking up. The procedure, which involves growing two-dimensional sheets of polymer nano crystals, is more efficient and controllable than current methods — according to the researchers, it's like making a lawn by putting down sod, rather than planting grass and hoping it grows.
