Aleksandar Zavaljevski received B.S. degrees in Mathematics and Electrical Engineering from the University of Belgrade, Serbia. He received M.S. degree in Electrical & Computer Engineering from the University of Belgrade, Serbia. He received Ph.D. in Electrical Engineering in 1996 from University of Cincinnati , Ohio , specializing in statistical classification and detection in multispectral medical and remote sensing images.

He worked for twelve years as a research engineer in Computer System Design Department of the Institute of Nuclear Sciences , Vinca , Serbia . There he led the project of design and implementation of a computer system for surveillance, detection and primary analysis of radio signals that was successfully completed with minimum resources. He conducted research in the area of detection and identification of radio signals, spectral methods for radio signal detection, recognition of signal modulations, adaptive software demodulation, radio source azimuth estimation, synthesis of digital filters with reduced coefficient sensitivity, design of techniques for frequency estimation of the sinusoid, design of optimal algorithms and programs for FFT on signal processors and computer architecture. He worked for eight years as a software engineer in GE Healthcare, Milwaukee Wisconsin . There he designed and implemented software for visualization on MR, CT, and X-ray medical scanners. He invented new methods for digital image magnification that were applied in Interventional CT scanners and enabled rapid image magnification with superior image quality. He designed and implemented software for CT image reconstruction and d esigned a web based system for automatic image comparison, difference image classification, and artifact detection . He is also teaching at the Strayer University .

Dr. Zavaljevski received Management Award for outstanding contributions to the Light Speed Ultra CT scanner at GE Healthcare. He received Annual Vinca Institute Award for the best scientific result for System ATS-1 for analysis of telegraph signals. Dr. Zavaljevski is a holder of six US Patents, two patents in Japan , one in Germany , and one with European Patent Office.
