Background and activities


Dr. Holmestad (born in 1967) is professor at Dept. of Physics NTNU (since 99).   Degrees: Dr. ing. (PhD) in materials physics, NTH, 1994, Siv. ing (MSc) in technical physics, NTH, 1991. Holmestad's present research interests are focussed on materials physics; transmission electron diffraction and microscopy (TEM), materials microstructure and the relation to macroscopic properties. Ongoing projects are on aluminium alloys, solar cell materials, electron diffraction and new functional materials. She has educated 16 PhD students and 67 MSc students, in addition to co-supervision of 8 PhD students. Holmestad has had several sabbaticals abroad - 6 months in 2005 and 2012, both at University of Illinois, Urbana-Champaign, IL, USA and 2 months at Monash University, Melbourne, Australia in 2019. Web of Science (April 2020): Cited documents = 220, Citations ~3300, h index = 30.

She has initiated and been project leader for several externally funded projects over the past fifteen years, funded mainly by the Norwegian Research Council and Hydro Aluminium. The main research projects she have been involved in are Quantitative convergent beam electron diffraction (2000-03), the SUP Micro- and nanostructural materials development (2001-06), the NorLight project Heat treatment fundamentals (2001-07), the Industry initiated project Nucleation control for optimised properties (2007-12), the FRINAT project Fundamental investigations of clustering (2007-11), the Japanese-Norwegian Al-Mg-Si precipitation project (2009-14 and 2019-2022), the FRINATEK project Fundamental investigations of precipitation in the solid state with focus on Al-based alloys (2013-17), the KPN project Fundamentals of intergranualr corrosion -FICAL (2017-2021) and last the KPN project Solute cluster manipulation for optimized properties in Al-Mg-Si   based Al alloys (SumAl)(2019-2024). In addition she has been leader of TEM Gemini Centre (SINTEF, NTNU) 2006, 2008-2013, and leader for a Nordic network within TEM in Nordforsk, NorTEMnet, 2010-2014. She was the project leader of NORTEM, Norwegian Centre of transmission electron microscopy, 2010-2013, 2017- >) a large scale infrastructure project in TEM, from SINTEF, UiO and NTNU (total project 115 MNOK, 2011-20). Since 2015 she is involved in the SFI project CASA, Centre of advanced structural analysis.
