Technical Editor

Jean-Jacques graduated from the Rochester Institute of Technology, where he completed his Master of Science in Electrical Engineering. In his studies, Jean-Jacques focused on Control Systems Design, Mixed-Signal IC Design, and RF Design. His research focus was in smart-sensor platform design for RF connector applications for the telecommunications industry. During his research, Jean-Jacques developed a passion for the field of RF/microwaves and expanded his knowledge by doing R&D for the telecommunications industry. Journalism was always a passion of Jean-Jacques’ as well. He enjoyed writing for RIT’s university publication in addition to working on white papers, patents, and technical articles.

Jean-Jacques is excited to cover the latest trends in research, technology, and products. He is also determined to help engineers gain access to information services, which will aid in the design process while preventing many engineers from having to "reinvent the wheel"--a problem that is so common to the field.
