Our lab uses biomedical imaging to improve human health. We are particularly attracted to ultrasound imaging because of its low costs and good temporal and spatial resolution. We work to improve the contrast of the images via nanoscale contrast agents, which can often double as drug delivery vehicles. Another approach to improving contrast is photoacoustic imaging. Photoacoustic imaging is a “light in/sound out” approach versus the “sound in/sound out” of conventional ultrasound imaging. It is based on the thermal expansion of target tissue or contrast agents after a nano-second light pulse. We are using photoacoustic imaging for a variety of applications related to human health. Click on the target tissues below to read more about our efforts to improve human health.
