Professor Hajimiri's research in medical engineering spans the fields of biosensors, drug delivery, terahertz imaging, and bio-inspired engineering. In biosensors, his group leverages electrical engineering and biochemistry to make very low cost handheld diagnosing devices for various diseases. They design and use silicon-based electronic chips in existing technologies for detection and monitoring of various conditions, such as cancer, tuberculosis, or hepatitis C. In therapeutics, they use magnetic particles for drug delivery in the brain. To accomplish this they have developed a sophisticated dynamic magnetic manipulation setup that allows them to ‘navigate' magnetic particles to deliver drugs to the targeted cancer sites for improved efficacy. They also have developed low-cost handheld imagers in the terahertz range of electromagnetic waves for low-cost medical imaging.
