Dr. David Nghiem is also the Chief Scientist of Global Wireless Technology (GWT), Inc. He invented many practical antenna technologies for state-of-the-art wireless-communication systems, including medical applications. In addition, he has been developing proprietary technologies, including MRI survivability/compatibility technology for medical device and bio-sensor applications, skin-cancer sensor technology, implant-explosive-device detection technology for home-land security and anti-terrorism applications, and efficient wireless power-charging technology.
Dr. David Nghiem was an Assistant Dean of the Cullen College of Engineering and a Director of the Telecommunication Center at the University of Houston. He has also spent many years in telecommunication and medical industries, including Harris Corporation, Qualcomm, USA Wireless and Medtronic. He is a Senior Member of IEEE and an avid researcher. His work has been published in leading academic and scientific journals. He has been providing the industry with fast turn-around, cost-effective, compact and more efficient antenna technologies. Dr. David Nghiem holds 14 US issued patents. He also discovered Leaky Dominant Modes for common stripline & microstrip-line transmission-line structures, and Anti-Radiation Modes for antenna structures. In 2016, the Twin Cities IEEE Section honored Dr. David Nghiem's outstanding engineering career with the IEEE Outstanding Engineer award for his accomplishments in the field of wireless communications, including medical applications.
Last, but not least, Dr. David Nghiem has been recognized for having very high standards for product quality and safety. He has been providing the industry with technologies that are not only more efficient, but also safer. Millions of cell-phone users are benefiting from his technologies. In 1997, Dr. Nghiem introduced the Advanced Cellular Phone Antenna (ACPA) technology that significantly reduces RF radiation absorbed into the user's head and improves the cell-phone system efficiency. Most of the cell phones currently in the market have their primary internal antenna mounted at the bottom as proposed in the 1997 ACPA solution.

Dr. Nghiem has committed to helping the medical industry and patients through his innovative technologies, including MRI safety technology for medical devices, and skin-cancer sensor technology. He has also developed an implant-explosive-device detection technology that could save many lives.
Dr. David Nghiem was invited to give the FDA a seminar on "Bluetooth Communication Systems for Medical Implant Applications" on July 15th, 2015. Bluetooth low-energy (BLE) technology has become a promising option for wireless medical-implant applications. However, an increased body loss at the ISM frequencies utilized in a BLE communication system and common interference sources, including Wi-Fi, IoT, microwave-ovens, wireless power-charging systems, etc. present challenges for medical implant applications. In the seminar, a Bluetooth medical-implant system analysis was presented. System, interference, and MRI survivability & compatibility testing were discussed. A simple and reliable measurement methodology that can be used to determine the conservative survivability/SAR/heating scenario was proposed. Dr. Nghiem was also invited to give a seminar on "Bluetooth Low Energy (BLE) & Medical Body Area Network (MBAN) Communication Systems for Implants and Medical Devices: Issues & Solutions" at the FDA on February 10th, 2017.
