Dr Kajal Mallick is an Associate Professor at WMG in the School of Engineering. He received his MMet in Applied Physical Metallurgy and an MPhil in Glass and Ceramic Science from the University of Sheffield, and his PhD in Physics from the University of Warwick. Dr Mallick was recipient of the prestigious IPGR (International Partners in Glass Research) Fellowship based at Connecticut, USA to work on theory and applications of glass research in industry. He is a Fellow of the Institute of Materials, Minerals and Mining (FIMMM) and member of the American Ceramic Society, The Minerals, Metals and Materials Society (TMS), Institute of Physics, European Ceramic Society, UK Society for Biomaterials and the European Society for Biomaterials. He has published over 90 refereed papers in leading peer reviewed high impact international journals as well as a number of contributed/invited conference papers with h-index of 12. Dr Mallick also holds one patent on tissue engineering. He has given a number of invited technical talks and guest lectures in USA, Canada, Switzerland, Japan, Germany and UK. He is Editor-in-Chief of a new journal Bioinspired, Biomimetic and Nanobiomaterials. He is a member of the Editorial Board of Advances in Applied Ceramics: Structural, Functional and Bioceramics. He is the organiser of biomaterials symposia for Materials Science and Technology (MS&T) and TMS annual international conferences. He sits on several national and international academic, technical and research committees and serves as a technical referee and reviewer for over 30 leading journals and international conferences. He served as a reviewer of proposals for the Wellcome Trust, i4i and European Framework.
Dr Mallick is an internationally renowned expert in the field of materials science and technology. He currently heads Tissue Engineering and Ceramic Processing research group (TiECeP) that includes a large number of undergraduate, MSc, PhD and EngD students, actively involved in a wide range of research projects supported by EPSRC, Royal Academy of Engineering, Advantage West Midlands and WIMRC and other research organisations.
His teaching and research areas of specialisations are very diverse. His research is focussed on synthesis, structure, processing and characterisation of materials including ceramics, glass and glass-ceramics, polymers, metals and biomedical materials.
Bone Tissue Engineering and Biomaterials
His current pioneering research is focussed on the design and development of novel biomedical materials and commercially viable scaffold manufacturing processes employed in the field of tissue engineering. Dr Mallick and Mr James Meredith, his EngD doctoral student have developed a patented technology that succeeded in producing ceramic monolith bone graft substitute (BGS) structures regarded ideal as bone scaffolds. A challenging combination of high compressive strength and porosity of over 60% has been achieved suited for specific clinical applications. This innovation relies on extrusion of ceramics to manufacture simultaneously highly porous and strong ceramic monoliths. Significantly, the technology is also able to utilise any combination of currently available FDA approved biomaterials such as hydroxyapatite (HAP)/nano-hydroxyapatite (nHAP), β-Tricalcium phosphate (TCP), lactide-glycolide copolymers, polycaprolactone (PCL) and other biologic materials to manufacture composite scaffolds. The ability to promote osteoblast adhesion and proliferation has been demonstrated for these constructs and compares favourably with the existing BGS material. Development of novel implants that will address specific clinical needs is ongoing. Warwick Ventures is now actively engaged in the commercialisation of this invention.
Freeze Casting of Biomedical Materials
In a related body of his biomedical research activity, Dr Mallick has also developed novel freeze casting processing methodologies to fabricate porous and interconnected 3-D networked glass and bioceramic bioscaffold structures suitable for bone tissue engineering applications where strength requirement is less demanding. Recently, he presented his work to an international audience at the 10th International Conference on Ceramic Processing Science (ICCPS-10) held in Japan and also at the American Ceramic Society sponsored 112th Materials Science and Technology (MS&T10) International conference in USA. This significant research is now published in a Special Issue of the American Ceramic Society Journal as one of the best invited papers. His research work has now appeared in several Special Book series of Ceramic Transactions. Recently, he has presented invited talks in the PAC RIM8 International conference in Canada.
Metalloceramics and Metallic Glasses as Medical Devices
This area of research concerns research and development of bioresorbabale metals and alloys as cardiovascular or other scaffold structures for use as both hard and soft tissue generation. The challenge of the design and development of suitable non-toxic and corrosion resistant alloy composition is being addressed together with their applications.
Functional, Technical and Electroceramics
His other areas of significant research impact include functional, technical and electroceramics for mobile and telecommunication applications. Notable is a series of important international journal and conference papers on the development of magnetodielectric inorganic hexaferrites for applications in telecommunications.
Processing of Nanoceramics and Nanostructured Materials
In the area of synthesis of novel materials, a substantial volume of his previous and more recent work is original leading the way to novel processing methodologies to be adopted by other researchers in the field. Specifically, his work on inorganic sol gel processing of nanoceramics has for the first time demonstrated the low temperature processing of ceramics such as titanates and aluminates.
Strengthening of Container Glasses
Dr Mallick has developed several surface strengthening techniques to produce container glasses with three times the strength but half the weight thus saving energy and enhancing recyclability. This research has contributed successfully to the development of processes used in container glass industry today.
Academic and Industrial Collaboration
Dr Mallick collaborates closely with various groups based in UK, USA and Japan namely, University College London, University of Cambridge, University of Sheffield, University of Nottingham, Nagoya University, Penn State, Swiss Federal Institute of Technology (ETH Zurich), University of Texas at San Antonio, Instituto de Ceramica y Vidrio, Spain, NGK, Japan.
Dr Mallick is active in raising public awareness of manufacturing/technology aspects of Biomedical Engineering and Automotive Engineering sectors through various media reports.
