Nilesh Madhu received his Dr.-Ing. degree (summa cum laude) from the Ruhr-Universität Bochum, Germany, in 2009. His dissertation was on signal processing algorithms for the localisation and separation of acoustic sources using microphone arrays. Following this he was awarded a Marie-Curie experienced researcher fellowship for a two-year postdoctoral stay at the KU Leuven, Belgium. Here he successfully applied his signal processing knowledge to the field of hearing prostheses and biomedical signal analysis.
From 2011 to 2017 he was with NXP Semiconductors, Belgium, where he held the positions of principal scientist and team lead within the product line Mobile Audio Solutions. During this period he and his team were tasked with developing innovative, beyond the state-of-the-art algorithms for audio and speech enhancement in mobile communications devices. This work, consistently held to exacting industry standards and strict delivery deadlines, led to the successful deployment of the algorithms on several flagship models of major smartphone OEM’s.
Since December 2017 he is a professor for audio and speech processing at Ghent University and imec, Belgium. He is passionate about signal processing and is especially interested in machine learning approaches for signal detection and enhancement for various applications in the fields of communications, healthcare, education and automation.
