Biographical Details:

Dr. Joseph Stokes, Head of School of Mechanical and Manufacturing Engineering in Dublin City University, was awarded the degrees of B.A. and B.A.I. in Mechanical and Manufacturing Engineering from Trinity College Dublin in 1997 and began his PhD studies that year in DCU. He attained his PhD in Mechanical and Manufacturing Engineering from Dublin City University in 2002, graduated March 2003. He lectured part-time for two years in Dublin Institute of Technology Bolton Street from 1998 to 2000. In September 2000 he became a member of the academic staff in the School of Mechanical and Manufacturing Engineering in Dublin City University Ireland. He was promoted to position of Senior Lecturer in DCU in 2009. He has been research active in the area of Surface Engineering since 1997. His professional achievement includes the production of coated and free-standing engineering components using the HVOF (High Velocity Oxy-Fuel) process, other processes include Atmospheric Plasma and Flame Thermal Spray (the only Thermal Spray facility in any University/Institution in Ireland), and Magnetron Sputtering PVD techniques, including Tribological Assessment. Applications of his research include: Wear Reduction, Bio-coatings for Implant Replacement Therapy, Oil and Gas Protective Coatings to mention a few. He is an active member of the Materials Processing Research Centre (MPRC) and the National Centre for Plasma Science and Technology (NCPST).
