BIOGRAPHY
received the B.S. degree in mechanical engineering from the University of California at Santa Barbara, in 2013, and the M.S. degree in electrical engineering from the University of California at Berkeley, in 2015, where he is currently pursuing the Ph.D. degree with the Department of Mechanical Engineering. His research interests include the development of MEMS for consumer devices and medical applications, and his graduate work focuses on the design and modeling of high-performance piezoelectric micromechined ultrasonic transducers and their systems.

Highly Responsive pMUTs [BPN743]
Ultrasonics has been realized as a nondestructive measurement method for a variety of applications, such as medical imaging,
healthcare monitoring, structural testing, range finding, and motion sensing. Furthermore, high intensity ultrasound can be used in
therapeutic treatments, such as lithotripsy for kidney stone comminution, hyperthermia for cancer therapy, high-intensity focused
ultrasound (HIFU) for laparoscopic surgery, and transcranial sonothrombolysis for brain stroke treatment. MEMS ultrasonic
transducers are known to have several pronounced advantages over the conventional ultrasound devices, namely higher resolution,
higher bandwidth, and lower power consumption. The main purpose of this project is to develop new architectures of Piezoelectric
Micromachined Ultrasonic Transducers (pMUTs) with higher electro-mechano-acoustical energy efficiency and increased sensitivity
while using CMOS-compatible fabrication technology, making them suitable for battery-powered handheld devices. The specific focus
is on increasing the electromechanical coupling, bandwidth, and acoustic pressure output in aims of creating power-efficient hand-held
medical devices for diagnosis/therapy.
