Working for Oerlikon AM GmbH Europe, I have worked on projects designed to create added value along the entire process chain for additively manufactured components, from alloy development to heat-treatment optimisation and other post-processing steps. One of my key projects has been on Surface Engineering of Additively Manufactured components. Starting from the development of a strategy, the creation of projects centred around the topic and the redaction of statements of work. Those activities were carried in collaboration with internal and external partners and reported such that the findings could be used in production and throughout the entire organisation. I have also worked on the influence of moisture in powders (Ti and Al-base alloys) on the material's mechanical properties. I have supervised a couple of PhD students working on developing new alloys ( titanium and high entropy alloys) for Additive Manufacturing (e.g. powder bed fusion - laser beam).
- Define and develop surface engineering strategy. - Support surface engineering needs across Oerlikon Businesses (PVD, CVD, thermal spray, laser cladding, additive manufacturing). - Develop and maintain strong relationships with industry partners, research institutes, customers on surface engineering topics.
- Management of R&D projects. - Develop R&D and Business Strategies in line with Oerlikon Surface Solutions. - Collaborate with external partners to expand internal capabilities. - Support internal teams for customer projects from different industrial sectors. - Communicate test plans, results and strategies via written technical documents and oral presentations. - Conduct hands-on laboratory work, collaborate and supervise with fellow team members.

I am in charge of various research projects and I also collaborate with researchers within the university as well as abroad, I supervise first and second years students in materials science and advising PhDs students. Projects I have been involved in : (i) Plastic deformation during fatigue and thermo-mechanical fatigue in a nickel superalloy processed by powder metallurgy; (ii) Creep damages in a novel cobalt base superalloy at high stress and high temperature. (iii) Micro-structural and mechanical behaviours of nickel base superalloy produced by selective laser melting (3D-printing - additive manufacturing). (iv) Micro-deformations of cubic boron nitride for abrasives.
Teaching 1st year Nat-Sci student materials science course for Emmanuel College, Cambridge. Organizing revision sessions and tests throughout the year.
PhD thesis : Studies of the fatigue behaviour in coarse grained RR1000. Thesis sponsored by Rolls-Royce plc. Characterisation of plastic damage at various temperature and scale using EBSD-SEM, TEM, X-ray synchrotron tomography, micro-pillar compression in coarse grain microstructure. Four publications written during the PhD.
Characterisation of green rust (iron oxide from wet corrosion of iron) using XRD, Rietveld refinement and synthesis of nano-particles of iron oxides by catalyse under ultra high vacuum. Project involving 5 researchers.
Studies of intergranular corrosion on valves carried for Volvo, Dpt. of materials technology. International project (France, Sweden, Germany, Argentina) with 8 academics and industrial researchers.
Updated the entire documentation for all the chemical products used within the factory. Wrote safety protocols for the factory's staff.
