Dr. Dennis J. Derickson, P.E.
Director of Engineering

Dennis Derickson received his BS, MS, and Ph.D. in electrical engineering from South Dakota State University, the University of Wisconsin- Madison, and the University of California – Santa Barbara, respectively. His farming background and amateur radio hobby both influenced heavily his career in engineering. He earned his State Farmer degree (Minnesota) with the FFA organization. In the world of radio communications, he holds an Extra-class amateur license (AC0P) and a First-Class Radiotelephone commercial license. He began his career at the research and development laboratories of Hewlett Packard in Santa Rosa, CA where he led development efforts for spectrum analyzer and vector network analyzer test and measurement instrumentation. His Ph.D. work involved the design, fabrication, and test of single-chip pulsed semiconductor lasers for data communication applications. 

After receiving his Ph.D., Dr. Derickson managed multiple project teams at Hewlett Packard for high-speed communication test systems. He worked as Director of Product Marketing at a start-up company called Cierra Photonics. After 21 years in industry, he joined the Electrical Engineering Department at California Polytechnic State University (Cal Poly) in San Luis Obispo. He served as Department Chair of Electrical Engineering from 2010 to 2020. His research activities have focused on applications of semiconductor lasers, wireless communication systems, and RF/microwave and millimeter-wave electronics. 

Dr. Derickson is the editor of two books; Fiber Optics Test and Measurement (1997) and Digital Communication Test and Measurement (2008). With many collaborators, he has created over eighty publications and seven patents. He is a founding member of the company Insight Photonics Solutions that is commercializing research initiated at Cal Poly SLO (http://www.sweptlaser.com/). His outreach activities have focused on creating and running summer science camps for secondary school students at Cal Poly and through the California 4H Youth Development Program. His current activities include Industry/Alumni research partnerships, entrepreneurship, enabling a project-rich hands-on environment for diverse students, and supporting a strong graduate research program. Dr. Derickson is a registered Professional Engineer (EE: #23555) with the State of California and enjoys helping others with his expertise.

Emilio Franchy received his BS in civil engineering from California Polytechnic San Luis Obispo, where he initially worked in the civil engineering field. Emilio decided to make a career change to cellular and wireless communications, and started his new career with Hewlett Packard as an Application Engineer supporting their mobile conformance test, base station test, and coverage confirmation drive test product lines. As an AE, he was responsible for product demonstrations, customer presentations, and customer training on use of HP products for applications to wireless communications facilities test and measurement.

After the test and measurement division of Hewlett Packard spun off to become Agilent Technologies, became a Business Development Manager for the Americas region, initially focused on product lines for coverage confirmation drive test, later extending into base station test and mobile test products. As a BDM, his responsibilities included market assessment, business strategy, customer presentations, and delivering technical seminars. 

After a successful career at HP/Agilent, Emilio joined Anritsu's Microwave Measurement Division, were he became a Product Manager for cellular base station test products covering spectrum analysis, cable & antenna analysis, 2G/3G/4G/5G modulation and signal analysis, and signal generation. Emilio later assumed responsibility for Anritsu's Passive Intermodulation (PIM) products, coverage drive test, RF-over-Fiber, and public safety product lines. 

Emilio is a fluent in both Spanish and English, and is a registered Professional Engineer (CIV: #45698) with the State of California. In his spare time he enjoys music and sports.
