Cecilia Giachelli, PhD

Cecilia Giachelli

Professor, Bioengineering
Adjunct Professor, Oral Health Sciences

Office: N-330L, Foege, Box: 355061


Current projects include:

  • Identifying and applying biomimetic strategies to cell-substrate interactions important for promoting endothelial survival and angiogenesis particularly in the context of biomaterial healing,
  • Biomolecular control of the foreign body reaction, with particular emphasis on the macrophage-mediated inflammatory response to biomaterials
  • Mechanistic studies aimed at developing novel therapeutic targets and approaches for preventing ectopic calcification in disease and medical devices
  • Cardiac valve and esophageal tissue engineering.
