B. Jin Chang, PhD is the President and Chief Scientist of SurgiTel, a division of General Scientific Corporation since 1992. From the late 1970s to the late 1980s, Dr. Chang led the development of advanced heads-up display systems for fighter jets such as the F15E, A10, and F4. Over the last 25 years he has been extending the ergonomic principles used for military display systems to clinical vision systems. This has led to SurgiTel’s family of ergonomic loupes and illumination systems which prevent chronic neck and back pains and protect eyes from the hazards of LED blue light. Also he led the development of touch-free LED light to prevent cross contamination and loupe-mounted video cameras which can be displayed with smart phones or tablets. Karl has been with SurgiTel for five years, during which he has met many clinicians with avoidable working pain. He is working hard to spread the news to clinicians that working in pain and risking injury is not part of the job!   http://surgitel.com/
