Why did you choose KAUST? 

A few years ago, it was only a dream to have a graduate school like KAUST in the Middle East with very high class academic standards and cutting-edge laboratories. The University’s location near Makkah and Madinah also attracted me. Because of all of these factors, I decided to start my research journey at KAUST. 

How is KAUST helping you to fulfill your dream?

At KAUST we are blessed with amazing research resources, such as the University’s high end laboratories with state-of-the-art equipment and talented academic and technical staff. I feel fortunate to have joined the KAUST Sensors Lab, where my research interests are perfectly matched and I receive genuine support from the Sensors Lab team, and particularly from my supervisor, Prof. Salama.

What is your research topic?

My research is about fully integrated RF power harvesters ("wireless power receivers"). The wireless power receivers can replace the battery in any micro-system to produce sustainable, battery-less devices. Our main target application is bio-medical implantable devices. We are aiming to produce a sustainable and battery-less bio-medical sensor that can be implanted in the human body once – it would remain in the body for the patient’s lifetime and there would be no need for further surgeries to replace the implanted sensor or its battery, as it is a battery-less device. 
Fully integrated wireless power receivers have a lot of applications, such as RFIDs, contact-less smart cards, supply chains, smart buildings, and home automation.

What is your research accomplishment so far?

We have already designed and implemented a microchip as a single chip implantable solution for an intra-ocular pressure monitor. The microchip contains a fully integrated RF power harvester as a wireless power receiver; this makes it a battery-less sustainable sensor. We designed and measured the sensor chip at the KAUST Sensors Lab and in the Core Labs. 
For the research, I was awarded the DOW Sustainability Innovation Student Challenge Award (SISCA) for 2012. My research work on the chip was published as a first authored publication in the IEEE Transactions on Microwave Theory and Techniques (the top journal in the IEEE Microwave Theory and Techniques Society [MTT-S]) in a special issue of “Bio-medical Applications of RF/Microwave Techniques.” The full system-on-chip was presented at the IEEE MTT-S International Microwave Symposium (IMS) at Seattle, WA (June 2013). This is also the top conference for the IEEE Microwave Theory and Techniques Society. 
I also won second place at the Microelectronics Olympiad in 2012 held in Armenia. I competed with 417 participants from 17 countries.

What do you think about the KAUST environment and social life?

KAUST is a wonderful place to live, research, work, and enjoy life. It has a fantastic campus with an amazing view of the Red Sea. However, I feel the KAUST community’s main “special ingredient” is that it empowers and enriches as its members make progressive achievements. KAUST also has a unique and diverse community, so now I have friends from almost every part of the world.
