About Brian Chang

Hi, I am an experienced R&D Engineer with a strong background spanning mechanical design, algorithm development, and product development for innovative technologies in the medical device, consumer electronics, and defense industries.Through careful testing, simulations, CAD, and DfMA, I specialize in optimizing designs and solving complex engineering problems. My experience spans taking concepts from initial design through testing and validation to deliver reliable, manufacturable solutions. In addition to my core mechanical engineering skills, I bring extensive experience in algorithm development, instrumentation/automation, signal+image processing, and PID controls, developed through academic research, personal projects, and professional endeavors. Beyond technical expertise, I have a passion for knowledge-sharing, whether mentoring team members or engaging in collaborative problem-solving. If any of this aligns with the challenges you\'re working on, or if you\'d simply like to connect, don’t hesitate to reach out!
