New catalysts for biomass conversion, new sorbents for CO2 capture or H2 storage, self assembly of nanoscale building blocks to make new materials, new biomaterials for medical devices, new electrode materials for batteries and new membranes are among the topics being explored in the Chemical Engineering Department. We develop and employ both computational and experimental approaches.
The Baker lab studies how structure and mechanics of the cellular microenvironment guide fundamental cell processes such as migration, proliferation, and extracellular matrix synthesis. To do so, we use microfabrication technologies to create synthetic biomaterials that mimic the 3D, fibrous nature of stromal or interstitial tissues. Combined with molecular tools, live imaging, microfabrication/fluidic techniques, and multi-scale mechanical characterization, these materials allow us to model, study, and control the interactions between cells and their surroundings. Ultimately, we aim to 1) shed insight into extracellular matrix-mediated diseases such as cancer and fibrosis and 2) use material cues to direct cell function for tissue engineering and regenerative medicine applications.

Arming nano-electronics with mobility extends artificial systems into traditionally inaccessible environments. Quantum-confined nanoparticles (0D), carbon nanotubes (1D), graphene (2D) and other crystalline materials with well-defined lattice structures can be incorporated into polymer microparticles (i.e., colloidal electronics), granting them unique electronic functions. The Liu laboratory seeks to advance device capabilities for individual colloidal electronic particles, and explores higher-order assemblies of these building-blocks into hierarchical colloidal electronic matter. This research program, positioned at the intersection between materials design, chemical catalysis, and electronic device fabrication, aims to address one central challenge: Can we build materials the way nature builds us?
