  2. About Jannick P. Rolland

    Jannick P. Rolland

    Jannick Rolland is the Brian J. Thompson Professor of Optical Engineering and Associate Director of the R.E. Hopkins Center for Optical Design & Engineering, and Professor of Biomedical Engineering at the University of Rochester.  Dr. Rolland also runs the Optical Diagnostics and Applications Laboratory (ODALab).


    1. We leveraged emerging technology that is coming out of cell phones, like liquid lenses, and developed a new way to record the data using a spectrometer and dynamic focusing...A liquid lens is made of water and oil on an electrode. When voltage is applied, the surface of the electrode becomes less hydrophobic...By changing the voltage, you can make things more or less hydrophobic and have the water being repulsed or attracted toward the electrode...The oil-water interface changes and you create bending, the different curvature at the interface" which serves as the lens. Changing the voltage changes the focus.

    2. My hope is that, in the future, this technology could remove significant inconvenience and expense from the process of skin lesion diagnosis...When a patient walks into a clinic with a suspicious mole, for instance, they wouldn't have to have it necessarily surgically cut out of their skin or be forced to have a costly and time-consuming MRI done. Instead, a relatively small, portable device could take an image that will assist in the classification of the lesion right in the doctor's office."
