Results‑focused engineer and researcher with 5+ years of both embedded software and hardware development experience, specializing in low‑power operation and networking. I am passionate about exploring novel ideas, connecting software and hardware into groundbreaking products. My work has received international media attention and is incorporated into products that are sold to this day.
Recently, I succesfully defended my PhD dissertation “Towards Deployable Battery-Free Networked Systems”, supervised by dr. P. Pawełczak and prof. dr. K.G. Langendoen at the Embedded Systems group at the Delft University of Technology.
My PhD research focused on turning the Internet of Things (IoT) battery‑free and solely powered by harvested energy, as batteries are a pollutant to the environment and have a limited lifespan. Through novel hardware architectures and software methods, my research pushed the boundaries of battery‑free systems and explored ultra‑low power networking, timekeeping, debugging and interactive devices. Enabling many connected and interactive battery‑free IoT applications solely powered by ambient energy.

We present an architecture for intermittently-powered wireless communication systems that does not require any changes to the official protocol specification. Our core idea is to save the intermediate state of the wireless protocol to non-volatile memory within each connection interval. The protocol state is then deterministically restored at a predefined (harvested energy-dependent) time, which follows the connection interval. As a case study for our architecture, we introduce FreeBie: a battery-free intermittently-powered Bluetooth Low Energy (BLE) mote. To the best of our knowledge FreeBie is the first battery-free active wireless system that sustains bi-directional communication on intermittent harvested energy. The strength of our architecture is articulated by FreeBie consuming at least 9.5 times less power during device inactivity periods than a state-of-the-art BLE device.
