Alastair Sloan is the Head of School in the School of Dentistry and began his tenure in this role in August 2017. He holds a substantive post as Professor of Bone Biology and Tissue Engineering in the School of Dentistry and is a member of the Cardiff Institute for Tissue Engineering and Repair (CITER) at Cardiff University. Alongside his role as Head of School, he co-led the MIneralised Tissue Research Group in teh School until the creation of the Regenerative Biology Group.

He obtained his BSc in Biomedical Sciences from the University of Wales in 1993 and his PhD in Oral Cell Biology from The University of Birmingham, UK in 1997 in the Faculty of Medicine and Dentistry. Following postdoctoral research he was appointed to a Lectureship in Oral Biology at the School of Dentistry in The University of Birmingham in 2000. In 2005, he moved to the School of Dentistry and was awarded his personal chair in 2012. He is a Fellow of the Higher Education Academy and in 2018 was elected to Fellow of the Royal Society of Biology (FRSB).

Professor Sloan's research is multi-disciplinary and focussed on the repair and regeneration of mineralised tissues and the behaviour and therapeutic use of dental pulp stem cells. He is interested in the cellular and molecular responses of these cells to natural biomatrices and compromised biological environments to understand their functional behaviour during tissue injury and developing methods to mediate natural repair processes in bone trauma. Complimentary to this work, he is also interested in understanding the heterogeneity within dental pulp progenitor populations and their function in 3D environments.   His research is also focussed on understanding bacterial invasion and attachment in dental and bone infections and development of novel delivery mechanisms for antimicrobial agents to control infection within these tissues. In support of these studies, he has significant interest in the development of 3D organotypic culture models to provide high throughput model systems with high reproducibiilty and address the 3Rs in this field of bioengineering.

With a background in biosciences and oral biology, Professor Sloan has teaching responsibilities on the BDS programme where he contributes to the Oral Ecosystems course (year 2). In addition he teaches on the MSc Tissue Engineering and MClinDent programmes and the MSc Oral Biology programme.

Professor Sloan is the recipient of several awards and honours. In 1998 he was awarded the IADR, British Division's Mineralised Tissue Research Prize and several of his students have won national research prizes including the IADR British Division Mineralised Tissue Prize in 2008, 2013, 2014, the British Division Unilever Poster Prize in 2012 and the TCES Poster Prize in 2014. Professor Sloan was the President of the Pulp Biology and Regeneration Group of the IADR in 2010-2011. In 2011 he was awarded the IADR Distinguished Scientist Award, the Young Investigators Award, in recognition of his research to date. He holds a Visiting Chair at the Fourth Military Medical University in Xi'an, China since 2013, Dalian Medical University since 2015 and China Medical University since 2016. In 2019 he was appointed as Adjunct Professor in the College of Medicine and Dentistry at University College, Cork.

From 2015-2017 Professor Sloan was Chair of the Cardiff Insitute for Tissue Engineering and Repair (CITER). He currently sits on the Management Committee of the British Society for Oral and Dental Research (BSODR), the Executive Committee of the Tissue and Cell Engineering Society (UK) and the Grant Assessment Panel of the NC3Rs. He acts a reviewer for all RCUK funding bodies and the EU. He has attracted research funding from the NC3Rs, Health and Care Research Wales, MRC, EPSRC, Dr Hadwen Trust and Dunhill Medical Research Trust along with those from the industrial sector (Philips, Renishaw plc). He has been an active member of the Cardiff Institute for Tissue Engineering and Repair (CITER) since 2005 and is a member of the 3 further University research networks; Materials, Nanosome and CURE-Infection.

Research Interests

My research interests are within the field of mineralised connective tissues, focussing on the reparative potential and behaviour of the dentine-pulp complex and bone. I am interested in the signalling processes that initiate and control the repair of the dentine pulp complex, in particular the role and function of the dental pulp stem cells (DPSCs)  in mediating this reparative process in. In addition, I am interested in the potential therapeutic roles of these DPSCs in the wider context of regenerative medicine, specifically neural repair and spinal cord injury and smooth muscle regeneration from bladder tissue repair and understanding their biological function in vitro and in situ and the heterogeneity in these cell populations.

Research is also focussed on understanding the dentinogenic and osteoinductive properties of dentine and bone matrices to facilitate novel tissue engineering methodologies and natural regenerative processes. Knowledge in these areas will allow us to develop ways of exploiting endogenous growth factor involvement in mineralised tissue repair for novel treatment modalities in restorative dentistry and implantology. This has allowed me to develop a research programme directly related to the development of novel clinical therapies and methods in relation to dentistry and orthopaedics regarding tissue regeneration and repair.

In relation to this we are also heavily focussed on development of novel antimicrobial carriers / restorative materials for clinical endodontics and vital pulp therapy. We have established nanocarriers for antimicrobial delivery and prototype restorative materials and model systems to better understand the nature of the bacterial / pulp environment during pulpal infection. I have a long standing interest in developing novel in vitro / ex vivo organ culture model systems for mineralising tissues to provide innovative models for tissue regeneration/engineering and testing of novel therapeutic agents and advancing the 3Rs (reduction, replacement refinement) in biomedical research.
