“Dr. Keem has worked with me very closely at Language Testing International for many years. He upgraded our technology repeatedly during that period keeping us in the front of technology that was appropriate for our international business, while meeting very stiff deadlines on a consistent and fully reliable basis. It was a pleasure working with him and I look forward to doing so again in the very near future.”

Dr. Keem studied Columbia University, where he completed his Master of Science as well as his Ph.D. in Electrical Engineering.
Dr. Keem has published many papers in peer-reviewed technology journals. He also lectures in the fields of Artificial Neural Networks (ANN), Wavelet Transformations, Image Processing, Pattern Recognition, data classifications, fiber-optics applications and biomedical engineering. He also holds two patents for data and information processing.

He led the development of numerous biomedical projects including Quantitative Coronary Arteriography (QCA, St. Luke’s Hospital Center, NYC), skin wrinkle depth measurement (Johnson and Johnson), Digital Fiber Optic Trans-illumination and Analysis (DIFOTI, carries detection and quantification) and the Multispectral Skin Imaging and Analysis machine (MelaFind, early stage skin cancer detection expert system). Each project involves utilizing machine and algorithmic intelligence for multi-dimensional data processing.

As an entrepreneur, he served as the director of a biomedical company, Electro-Optical Sciences. While serving as the director of software development and applied research, the company successfully completed its IPO in October of 2006 (renamed as MelaSciences, Inc.).
