Graduate Degree in Medical Engineering

The Degree of Doctor of Philosophy offers two tracks: MedE only and Medical and Electrical Engineering (Med-EE).

Aims and Scope of Graduate Study in Medical Engineering

Our medical engineering research and education leverage Caltech's strengths in engineering, applied science, and other fundamental fields, to apply emerging technological advances to medicine, and to create innovative diagnostic, monitoring, and therapeutic systems. The program's goal is to close the gap between engineering and medicine. Our major areas of research include micro/nano medical technologies and devices, medical nanoelectronics, biomedical materials and biomechanics, fluidics and bioinspired design, and medical imaging and sensing.
