My research interests include machine learning, signal processing and information theory, specially in application to radar and wireless communication.

Ever since I started my PhD, I have been lucky enough to join forces with some leading companies in the technology and telecommunication sectors, such as Ericsson or Bosch, in order to carry out my research. From 2018 to 2021, I collaborated closely with Infineon Technologies AG around their radar sensors for IoT, adopted by companies like Google for touchless human-machine interaction.

Projects

As a research associate at the Fraunhofer Heinrich Hertz Institute (HHI), I am involved in several public and private research projects, including the following ones:

  • 6G-ICAS4Mobility — Integrated Communication and Sensing for 6G Mobility.
  • 6G-RIC — Germany-wide Research and Innovation Cluster for 6G Mobile Technologies.
  • KOMSENS-6G — Perceptive 6G Communication Networks with Integrated Sensor Technology.
  • AI4Mobile — AI-aided Wireless Systems for Mobility in Industry and Traffic.

Videos

In collaboration with HHI mm-Wave research group under the 6G-RIC project. The demo has been or will be showcased live at IEEE MILCOM 2024, Berlin 6G Conference 2024, EuCNC & 6G Summit 2024, and IEEE 6G Summit Dresden 2024 (Best demo award).
