Details:
Costel Rizescu, Ph.D., is a professor in Physics and Biomedical Equipment Technology, coordinating the Biomedical Equipment Repair Training Program, and is the director of MediSend’s Global Education Center in Dallas, TX. Additionally, he holds the position of director of the Biomedical Repair Laboratory at MediSend International, managing activities of refurbishing biomedical equipment in support to the distribution of medical equipment and supplies to developing countries, in long-term and disaster relief programs. A Romanian national (native), Costel Rizescu received a Master of Science degree in Nuclear Physics Engineering from University of Bucharest, Faculty of Physics in 1990 and a Doctor of Philosophy degree in Physics from University of Bucharest in January 2001. Costel has almost 20 years experience in nuclear physics and medical imaging research, biomedical equipment development and entrepreneurial start-up, as well as in education.

Costel Rizescu began his R&D career at the Research and Design Institute for Electrical Engineering in Bucharest, Romania. Here, as a research scientist, he designed, developed, manufactured, tested and operated first Romanian X-and Gamma Ray CT scanners, impedance tomography scanners, lithotripters, ultrasound systems, and digital data archiving systems with radiography films. He also developed radiation detectors, X-and Gamma Ray collimators, torque sensors for computerized testing of electro-mechanical systems, and performed experiments to improve the reconstruction algorithm of electrical impedance tomography for medical applications. Costel Rizescu pioneered applications of CT imaging in archaeology, geology, forestry, marine research, and airport and customs security in Romania, and performed extensive research activity in Computer Tomography technology, with applications in various science domains: nuclear medicine, biomedical engineering, applied physics, oceanographic and marine science, archaeology, micro technologies, geology, and non-destructive testing and evaluation. He also participated in 11 international workshops and cooperative projects.

Costel Rizescu has earned an international reputation and recognition for innovation and creativity. He is the author of 24 international refereed articles in science, 7 of them published in top-ranked international scientific journals like Nuclear Instruments and Methods, Deep Sea & Oceanographic Research, Archaeological Science, Trace and Microprobe Techniques, Non-Destructive Testing Evaluation, and Neues Jahrbuch für Geologie und Paläontologie Abhandlungen.
Throughout Costel Rizescu’s career, he has received many citations for his scientific work, including being listed in more than thirty reference books, scientific articles and patents, most of them in nuclear medicine and biomedical engineering domains. His own original method, published in Nuclear Instruments and Methods Journal (“Determination of local density and effective atomic number by the dual-energy computerized tomography method with 192Ir radioisotope”), has been representing for many years a reference source for published material in professional publications written by other authors in top-ranked journals like Medical Physics, Biomedical Engineering, Nuclear Instruments and Methods, Applied Physics, Trace and Microprobe Techniques, Optoelectronics, Photonics, Non-Destructive Testing Evaluation, Advanced Materials, etc., as well as for prestigious scientific books and an industry patent in the U.S.

While maintaining a high-level research agenda, in 2000 Dr. Rizescu began to extend his area of expertise into the biomedical entrepreneurial start-up. At PHOENIXMED – one of the largest Romanian vendors of medical supplies, Costel started-up a biomedical equipment department, where, as a head of the department, he identified target markets for biomedical equipment, produced reports and strategic recommendations to top executives, provided technical support and training for his staff and customers in operating, maintaining and repairing biomedical equipment, and installed software on clinical systems. In 2002, Costel started-up his own company, LabSystems, where he developed a division in developing and manufacturing biomedical equipment such as spectrophotometers and sterilizers.

After moving to the U.S. in 2005, Costel Rizescu continued to broaden his knowledge and skills by volunteering for MediSend International. He designed, planned, organized, and conducted all technical projects for starting-up a 3,600-sq. ft. state-of-the-art biomedical laboratory for refurbishing medical equipment. Volunteering for MediSend gave him the chance to learn and develop new skills, make important networking contacts, gain work experience and build his self-esteem and self-confidence whilst making an important contribution to society. Late that year, Costel Rizescu came aboard of MediSend International as the Director of the Biomedical Repair Laboratory.
In 2006 at MediSend International, Costel Rizescu created a unique Biomedical Equipment Repair Training Program for trainees from developing countries, a milestone considered to be the first in the world. He has adopted an interdisciplinary and research-based approach to education, focusing on specific assessment and instructional strategies derived from the research and using the best teaching practices in order to meet the performance based training program’s outcomes. The “100% student mandatory passing” outcome-oriented curriculum, centered on biomedical equipment repair, integrates courses of six science disciplines and over thirty different biomedical instrumentation technologies. He has been running this program for two years and, actually, he is engaged in planning, designing and building new medical programs that will meet the needs and challenges of hospitals in developing countries.
