Penn Dental Medicine

Dr. Koo’s research focuses on understanding how biofilms cause oral infectious diseases and seeking new therapeutic strategies to control biofilms. His group has applied engineering methods and nanotechnology to study bacterial-fungal biofilms in childhood caries and nanoparticles for caries prevention. He also developed the first micron-scale robots for automated dental biofilm eradication. He is an elected fellow of the American Association for the Advancement of Science (AAAS) and the recipient of the International Association for Dental Research (IADR) Distinguished Scientist Award.

Kathleen Stebe, PhD, Co-Director

Kathleen Stebe, MSE, PhD »
Goodwin Professor of Engineering and Applied Science
Penn Engineering

Dr. Stebe’s primary research interests are in non-equilibrium interfaces, with applications ranging from microfluidics to nanotechnology. One aspect of her research program focuses on interfaces between fluids and how surfactants can be used to influence interfacial flows. Other aspects address tailoring of solid-liquid interfaces with applications ranging from patterned electrodeposition to capillary-driven assembly and ordering of nanomaterials.
