John Haycock is Head of Materials Science and Engineering and a Professor of Bioengineering. He joined the department in 2001 from the Medical School at Sheffield University where he was a Research Fellow. He obtained his first degree and PhD in Biochemistry at Newcastle University and was a PDRA at Albany Medical College in New York. His research group is based in the Kroto Research Institute.

Research interests

nerve tissue engineering3D in vitro models of nerve3D in vitro models of skin3D ImagingBioactive surfaces

John's research spans five interdisciplinary themes:

1. Nerve tissue engineering. The design of nerve guidance channels for repairing traumatic peripheral nerve injury – combining biomaterials, 3D fabrication, neuronal, glial and stem cell research.

2. 3D In vitro models of nerve. The use of 3D scaffolds and neuronal / glial co-cultures for 3D in vitro models of nerve as an alternative to animal models for disease, disorder and testing research.

3. 3D In vitro models of skin. The use of 3D scaffolds and keratinocyte / fibroblast co-cultures for 3D in vitro models of skin as an alternative to animal models for inflammatory testing.

4. 3D Imaging. Confocal and 2-photon microscopy + Time resolved microcopy imaging

5. Bioactive surfaces. Anti-inflammatory and anti-microbial surfaces for medical applications

John also has an interest in single and 2-photon laser scanning microscopy for supporting a number of interdisciplinary research programmes, including tissue engineering. He was responsible for establishing the confocal and multiphoton imaging facility in the Kroto Research Institute funded by the BBSRC with support from Carl Zeiss.
