Acoustics Research Unit
Professor Carl Hopkins
Carl is Head of the Acoustics Research Unit. His research interests include the prediction and measurement of sound and vibration in and around built-up structures, with emphasis on structure-borne sound transmission.
Dr Pyoung Jik Lee
Pyoung Jik is a Lecturer in the Acoustics Research Unit. His research interests include psychoacoustics, soundscapes, environmental noise, speech privacy, impact sound insulation, and room acoustics.
Dr Gary Seiffert
Senior Research Fellow within the Unit. His main areas of expertise are in acoustic instrumentation and measurement techniques. His research interests include work in physical acoustics to investigate the possibilities of using sonic cleaning to dislodge dust and to clean industrial plant that is not easily accessible.
Natalie is a part-time Research Associate in music education for children with a hearing impairment. She is a trained musician and music teacher and her work in the Acoustics Research Unit focuses on the introduction of vibrotactile technology into schools.

Professor Barry Gibbs
His research interests include structure-borne sound, machinery noise, vibration and sound insulation. He serves on national and international standards committees and has acted as consultant in room acoustics, environmental noise and for noise control engineering.
Professor David Oldham
His research interests are the fields of noise control in building services, the enhancement of room acoustics by active techniques and computer modelling in acoustics. He is also responsible for liaison with professional institutions.
Recently retired after a distinguished career as an Environmental Health Officer with over 35 years experience of environmental protection and pollution control, Dave is an active member of the Chartered Institute of Environmental Health and the Institute of Acoustics. As Sefton's Environment Section Manager, with responsibility for noise control and prevention, he gained extensive experience of dealing with noise nuisance from a wide range of industrial, commercial and domestic sources and a comprehensive knowledge of the legal, planning and licensing issues associated with noise control. Dave is involved with the provision of CPD courses in environmental noise with Dr Gary Seiffert.
Marios Filippoupolitis graduated from Patras University with a BEng and MEng in Civil Engineering. He has an MSc in Advanced Structural Analysis of Monuments and Historical Constructions from the Universities of Minho and Padova. Marios completed his MPhil in the ARU on finite element modelling of dowelled timber-joist floors that was funded by the Swiss National Science Foundation (supervised by Prof. Carl Hopkins). Marios is now registered for PhD study on structure-borne sound transmission in fragmented building structures after earthquakes. This is funded by the CDT of the University of Liverpool’s Institute for Risk and Uncertainty and Marios is supervised by Prof. Carl Hopkins and Prof. Ivan Au (Engineering).
Alessia Frescura graduated from the University of Bologna with a Bachelor and Master degree in Architecture and Building Engineering for which her thesis was a collaboration with the Audioscan practice in Barcelona concerning acoustics in eating establishments. Alessia joined the Acoustics Research Unit in October 2017 as an Early Stage Researcher (ESR) in the EU Marie Curie project, ACOUTECT, studying for a full-time PhD on psycho-physiological evaluation of human exposure to floor impact sounds in lightweight buildings. The PhD is supervised by Dr PJ Lee and Prof. Carl Hopkins.
Nazmiye Gulenay Yilmaz
Nazmiye Gulenay graduated from the Bilkent University with a BA in interior architecture and environmental design in 2015. She completed her Master's Degree in University of the Arts London in Interior and Spatial Design in 2017. She joined the Acoustics Research Unit in February 2019 as a full-time PhD student under the supervision of Dr PJ Lee and Prof. Carl Hopkins. Her research concerns the effects of sound on the perceived enclosure in urban environments such as street canyon and courtyard.
Steffi Reinhold graduated from the Hochschule Mittweida (University of Applied Sciences) in Germany with a BSc in Physical Engineering that had a focus on Technical Acoustics. Steffi is working on acoustics at the University of Applied Sciences in Stuttgart and joined the Acoustics Research Unit in September 2013 as a part-time PhD student under the supervision of Prof. Carl Hopkins and Prof. Barry Gibbs. Her research focuses on complex time-varying structure-borne sound sources in buildings which forms part of a larger research project funded by the German government.
Xiaoxue graduated with a Bachelor and Master degree in Engineering from Central South University in Changsha, China. He joined the Acoustics Research Unit in 2018 as an Early Stage Researcher (ESR) in the EU Marie Curie project, ACOUTECT, studying for a full-time PhD on modelling of structure-borne sound transmission in lightweight buildings. His PhD will focus on the development of prediction models that can inform engineering design on noise and vibration transmission in lightweight buildings, particularly from machinery and impacts from people. Xiaoxue is supervised by Prof. Carl Hopkins and Dr PJ Lee.
Song Ziwei graduated with a Bachelor and Master’s Degree in architecture from the University of Dundee in June 2019. He achieved the Royal Institute of British Architects (RIBA) Part 2 and joined the Acoustics Research Unit in October 2019 as a full-time PhD student under the supervision of Dr PJ Lee and Prof. Carl Hopkins. His research concerns the effects of noise in hospitals, especially ICUs.
