Profile Summary

My principal research interests lie in the field of biomedical optical spectroscopy, image and signal processing, and their applications in medical diagnosis. I have been investigating the perfusion imaging spectroscopy of the retina eye using a scanning laser ophthalmoscope. I have developed the method of spectral perfusion imaging of the retina that utilities SLO together with two red and infrared lasers in order to present the relative oxygen levels of the retina. Using image processing for detection of capillary non-perfusion in fluorescein angiogram of eye is another field that I have recently been developing. My future research plans are built on the foundations to further develop in the Medical image and signal processing, biomedical measurements, and the clinical applications that would serve as a way to follow disease progression and evaluate treatments in patients.
