Developing new diagnostic and prognostic tools based on optical coherence tomography (OCT)
In our group, we focus on developing optical imaging technology and applying it for biomedical research. Our current work is driven by the need for better and more reliable methods for medical diagnostics as well as by the desire to understand basic biological and medical research questions. To that end, we develop our own optical imaging systems and techniques, primarily based on optical coherence tomography (OCT).
Some of the techniques we employ in our lab include polarization sensitive OCT (PS-OCT), contrast agent enhanced OCT (CE-OCT), optical coherence elastography (OCE), OCT angiography (OCTA), multimodal fluorescence imaging, and assorted functional OCT methods.
We then use these custom imaging systems and methods to perform preclinical imaging in longitudinal studies of eye and brain disease models to better characterize disease progression with the goal of bringing better diagnostic indicators to the clinic.
Beyond preclinical research, we are also currently developing a novel optical imaging system for characterizing tissue samples for more personalized medical treatment.
