He received the B.S. degree in electrical engineering from Sharif University of Technology and his M.S. and Ph.D. degrees in electrical engineering from Stanford University. He has also worked for Bell Laboratories, Philips Semiconductors, and Sun Microsystems. As a part of his Ph.D. thesis, he developed a time-varying phase noise model for electrical oscillators, also known as the Hajimiri phase noise model. In 2002, he cofounded Axiom Microdevices Inc. together with his former students Ichiro Aoki and Scott Kee based on their invention of the Distributed Active Transformer (DAT), which made it possible to integrate RF CMOS power amplifiers suitable for cellular phones in CMOS technology. Axiom shipped hundreds of millions of units before it was acquired by Skyworks Solutions in 2009.
He and his students also demonstrated the world's first radar-on-a-chip in silicon technology in 2004, showing a pair of 24GHz 8-element phased array receiver, and a 4-element phased array transmitter in CMOS. These were followed by a 77GHz phased array transceiver (transmitter and receiver) with on chip antennas that established the highest level of integration in mm-wave frequency applications and was a complete radar-on-a-chip. They also developed a fully scalable phased array architecture, making it possible to make very large scale phased arrays possible in 2008.
He and his team are also responsible for the development of an all-silicon THz imager system, where an integrated CMOS microchip was used in conjunction with a second silicon microchip to form an active THz imaging system, capable of seeing through opaque objects. They demonstrated various phased array transmitters around 0.3THz with beam steering using the distributed active radiator (DAR) architecture in 2011. Various applications of this system appear in security, communications, medical diagnostics, and the human-machine interface.
In 2013, he and some of his team members demonstrated a complete self-healing power amplifier, which through an integrated self-healing strategy, could recover from various kinds of degradation and damage including aging, local failure, and intentional laser blasts.
Between 2014 and 2017, he and his team demonstrated three major advances in imaging and projection technology using silicon photonics platforms. In 2014, they showed the first silicon-nanophotonics optical phased array transmitter capable of dynamic and real-time image projection, which serves as a lensless projector. In 2015, he and his team demonstrated a 3D coherent camera, using a silicon nano-photonics coherent imager (NCI) platform that demonstrated direct 3D imaging at meter range with 15-micron depth resolution.. In 2016, they devised and implemented a one-dimensional (1D) integrated optical phased array receiver demonstrating the first lensless flat camera for the first time, imaging a bar coding directly from the surface of a chip. In 2017, he and his team demonstrated the first integrated two-dimensional (2D) optical phased array receiver, imaging simple 2D patterns without a lens with a very thin optical synthetic aperture of a few microns, demonstrating the first lensless flat camera.
He is a Fellow of National Academy of Inventors (NAI). He was selected to the world's top 35 innovators under 35 (TR35) at age 32. He is an IEEE Fellow and has been the recipient of numerous other awards. He was recognized as one of the top 10 authors in the 60-year history of ISSCC in 2013. He holds 90 granted U.S. patents. He was one of 45 scientists invited to speak at the World Economic Forum in 2016. As of 2016, over half of his graduated PhD students have gone on to become university faculty members.
His favorite band is Pink Floyd.
