As part of his post-doctorate at Harvard University, he researched optical methods for measuring functional changes in the brain. His research group developed a system consisting of quantum sensors with which we measured the blood flows in the brain with very high sensitivity.  One way to do this is to illuminate the skull with a laser beam and count the photons that entered the brain and returned back, that is, measure the change of the reflected light as a function of time and space after it has interacted with the cortex, the cerebral cortex. Because today we have very sensitive cameras and sensors , we can use them to test the changes in blood flows, by measuring photons that have traveled the entire route to the cerebral cortex and been reabsorbed by the optical sensor.
Another area that Dr. Ozana researched during his post-doctorate is the identification of the effect of addictive substances on the brain with the help of non-invasive optical means and by using different connections between different areas of the brain and in addition the activation of machine learning and deep learning algorithms. By illuminating a number of points in the prefrontal cortex, and according to the optical reactivity, a measurement can show whether that person is under the influence of an addictive substance.

Dr Ozana is Head of the Optical Neuroimaging Lab.

The Optical Neuroimaging Lab at the Gonda Brain Science Center, focuses on neurophotonics, a combination of electro-optics and neuroscience for clinical and functional purposes, under the track of neuroengineering, and he intends to continue developing this field for brain research."
Part of the research in the laboratory is applied in collaboration with hospitals and research laboratories in Israel and around the world, and part of it will focus on developing new hardware and systems for the purpose of improving measurement sensitivity in order to monitor new phenomena that could not be monitored until now.
