About me

I am currently a PhD student in the Divison of Network and Systems Engineering under the supervision of Carlo Fischione and Viktoria Fodor. My research interests are physical layer wireless, distributed machine learning, edge networks, and industrial communications.

I received a bachelor's degree in Electrical Engineering '16 and a master's degree in Information and Network Engineering '18 both from KTH - Royal Intitute of Technology. After the completion of my master's thesis, I spent a couple of months working as a temporary contractor for ABB Corporate Research, assisting in the development of a novel PHY-layer protocol for ultra-low latency industrial communications called WirelessHP.

My current research focus is Wireless for Machine Learning, i.e. wireless networks protocols that are tailored to support distributed machine learning. Particularly, I focus on over-the-air computation to combine the gradients of deep neural networks by utilizing the superposition property of electromagnetic waves.
