The faculty and students in Cornell biomedical engineering apply engineering principles to design systems that effectively control the spatial and temporal delivery of medicines, to investigate the effects of medicines on cells and tissues, and to evaluate their preclinical and clinical efficacy. Efforts include systems to target medicines at precise sites, (for example to treat cancers), devices to control the rate at which medicine is made available to the body (for example, injections that last one month or more) and constructs to facilitate specific interactions with systems of cells or to understand their function (for example, to deliver vaccines, to sequence the genome of single cells or to understand the impact of outside influences on cells). The work integrates investigators working across length scales in all fields of engineering and also include investigators in chemistry, cell biology, genetics, immunology, veterinary medicine and human medicine. Resources at Cornell that support these research programs include: the Chemistry Nuclear Magnetic Resonance facility, the Cornell Center for Materials Science, the Cornell Nanofabrication facility and the Cornell Center for Biotechnology. Most projects involve investigators at the Cornell College of Veterinary Medicine and the Weill Cornell College of Medicine.
