If you wait to do everything until you're sure it's right, you'll probably never do much of anything.

I defended my thesis on 28th September, 2012. I worked with supervision from Prof. Peter Kinget (Columbia Integrated Systems Lab.) and Prof. John Kymissis (Columbia Lab for Unconventional Electronics). 

The title of my doctoral thesis is "Ultrasound Data Communications for Ultra-low-power Wake-up in Sensor Nodes". It is an interdisciplinary work that explores ultrasonic wake-up at different levels -- at circuit level, the design of the 4.4-uW wake-up receiver IC was crucial and at application level, looking at the effect of ultrasonic interferes and reverberations on system performance was important. In summary, the key contribution of the research was an order-of-magnitude reduction in the wake-up receiver power consumption compared to the state-of-the-art RF-based wake-up receivers.

Our team, consisting of myself and both my advisers, was awarded the $100K first prize in the Interdigital Innovation Challenge on 21st September, 2012 at Mobilize conference in San Francisco. More can be read in this press release.
