Anna Zakrzewska

Member of Technical Staff


Anna Zakrzewska is a research scientist at Nokia Bell Labs in Dublin, Ireland. Her main research interests are in the area of wireless communications and focus on self-organising networks, which benefit greatly from data analytics and machine learning. Several of her patented network management mechanisms are used to automate configuration of millions of small cells and Wi-Fi access points around the world. She received the M.Sc. Eng. degree in information and communication technology from Wroclaw University of Technology, Poland and the Ph.D. degree from the Technical University of Denmark (DTU) in 2008 and 2014, respectively. Prior to the Ph.D. studies, she was with NTT Communication Science Laboratories in Atsugi, Japan and the European Commission Joint Research Centre in Ispra, Italy. Anna was honoured with the Polish Ministry of Science and Higher Education Scholarship in the years 2005-2008 and recognized as the double finalist of the Google Anita Borg Memorial Scholarship in 2012 and 2013. She is a Senior Member of IEEE. Anna enjoys speaking about technology and often partcipates in various STEM outreach activities.
