  • TJ Mechanical engineering and machinery - Materials science, Surface roughness, Tool wear, Surface engineering, manufacturing, machining, welding


I am a Materials Engineering from Simón Bolívar University in Caracas Venezuela, with a MSc in Mechancial engineering from this same institution. I obtained my PhD in manufacturing processes from the Univeristy of Bath, UK.

I am currently conducting research together with the University of Strathclyde. The research is in the area of surface engineering focusing on developing metal matrix composites through the incorporation of a surface layer of ceramic powder to enhance erosion and corrosion characterisitcs of low carbon steel substrate.

Previous research conducted over the last 20 years has primarily been concerned with topics in the area of Materials Engineering with particular reference to metals and manufacturing processes. The work has ranged from contributions to metal cutting in the surface roughness of machined surfaces obtained by cryogenic machining, turning, milling, drilling and grinding processes, to studies on tool life, tool wear, cutting forces, residual stresses, prediction of surface roughness and optimization of cutting parameters. An additional major area has been in the joining of metals using welding processes namely MIG, MAG and TIG,. with analysis of heat inputs, penetration, optimization of welding variables, residual stresses and the machining of welds. 

In 2016 I obtained a MSc in Learning and Teaching in Higher Education from the University of Strathclyde. Also started to condcut educational research focuse on engaging students through collaborative and cooperative activities.

I am a Member of IMechE and a Fellow of Higher Education.



Area of research expertise - Outline

My research has been focused in three different areas.

Machining: study of tool life, tool wear, cutting forces, residual stresses, surface roughness prediction and optimization of cutting parameters.

Analysis of manufacturing parameters and power consumption in cryogenic machining of aluminium and stainless steel.

Welding: analysis of heat inputs, prediction of penetration and temeprature, optimization of welding variables, residual stresses. Influence of residual stress when machining weld beads.

Surface engineering: Effect of shielding gases, heat input and ceramic particle size on the development of ceramic coatings through Tungsten Inert Gas technique.

Current research activities.

Current research is focused on enhancing erosion, wear and corrosion properties in micro-alloyed steels through the deposition of ceramic layers using TIG tecchnique.

Desired research direction.
