Biography

Ian graduated from Trinity College Dublin in 2009, with a First Class Honours degree in Mechanical & Manufacturing Engineering. He stayed at Trinity College to undertake a Ph.D. in experimental sound source identification and acoustic interaction effects in turbomachinery.

After completing his Ph.D. in 2013, Ian joined the Efficient Energy Transfer group at Bell Labs Ireland (now Nokia Bell Labs). His research at Bell Labs has focused on acoustic noise mitigation methods using both cutting-edge acoustic metamaterials and traditional absorption methods, image processing of Schlieren images for non-invasive analysis of multiphase flows, and noise-source localisation of shelf products using array signal processing techniques. More recently, his research interests have extended into user-focused audio with topics such as spatial audio rendering, adaptive filtering for noise control, analysis of human speech and immersive audio communication. He also collaborates with artists as part of the Experiments in Arts and Technology programme, with projects involving sonification of non-audio data, projection mapping, and video and audio production.

Outside of work, Ian enjoys music, running and cinema.
