Distinguished Graduate: Joseph Jachinowski


jachinowskiJoseph K. Jachinowski, BSEE '79. Joseph "Joe" K. Jachinowski received a bachelor’s degree in electrical engineering from Ohio University in 1979. He also holds a master’s degree in electrical engineering from Washington State University.

Joe began his career with Varian Medical Systems in 1981, working on control system design for linear accelerators.

In 1983, he co-founded SEL with former Ohio University professor Dr. Edmund O. Schweitzer III. SEL designs and manufactures digital signal processors used to monitor and control electric power systems. Joe was responsible for software development at SEL, which has grown to be a leading provider of protective relays (with all credit to Dr. Schweitzer).

In 1985, Joe returned to Varian to ultimately manage all systems and software development for its medical division. He then conceived and led the design team for Varian’s most successful medical linear accelerator. Today, that product family treats more patients for cancer annually than any other radiation therapy device.

In 1990, he co-founded IMPAC Medical Systems, becoming chairman, CEO, and president. The world’s leading supplier of clinical and administrative information management systems for the field of cancer care, IMPAC products span the field’s spectrum, including anatomical and clinical pathology, oncology electronic medical records, medical imaging, cancer registry, decision support, and administrative management. Today, IMPAC’s products are used to manage cancer care in more than 2,500 cancer centers in 71 countries.

Joe led IMPAC through its initial public offering in 2002 before it was sold in 2005 to Elekta, AB., a Swedish medical device manufacturer. Currently, Joe is executive vice president for product development for the combined companies. He also serves as a director for Elekta Instruments AB; director for BMEI, a Beijing-based medical equipment manufacturer; and chairman of the board for Medical Intelligence GMBH.
