• I Initiated, planned and managed several concurrent research projects and sought collaborations with other researchers with different competencies to improve our joint results.
• I participated in several workshops and PhD courses related to Inorganic Chemistry, both domestically and abroad.
• For various audiences, I presented and defended my research at several internationally acknowledged scientific conferences, including ICMCTF and EuroCVD.My Research Findings:

Stockholm, Sverige

I investigated the wear of cutting tools when machining different materials. Using various analytical techniques and knowledge from many different scientific areas, I deduced the detrimental influence of calcium on the wear of alumina-based coatings. As part of my master thesis at the company (see below), I developed an atomistic model explaining the wear.

Västberga

"Wear on Alumina Coated Tools and the Influence of Inclusions when Turning Low-Alloy Steel".Characterization of wear and adhered workpiece material on alumina coated cutting tools when turning low-alloy steel. Elucidating what influence the inclusions in the steel have to the wear of the alumina coating, using SEM, LOM, XRD, AES, Wyko and EPMA. Results.

Gimo

Worked hands-on as a shift operator for different PVD systems (Oerlikon Balzers) used to coat cemented carbide. I was responsible for the continuous operation and upkeep of the systems. The work demanded great sense of care as the coating process was the last step before packaging and delivering to customers.

Forsbacka

Process optimization of cooling system for hardening of steel. Investigations and documentations of several different process parameters, hardness testing and metallographic investigations. Conclusions made by usng several statistical methods, including Student's T-test and analyses of variance (ANOVA).
