She has educated 19 PhD students and 70 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 (Oct 2021): Cited documents = 240, Citations ~4100, h index = 35. See also Google Scholar.

She has initiated and been project leader for several externally funded projects over the past twenty years, funded mainly by the Norwegian Research Council and NOrwegian aluminium industry. In addition she has been leader of TEM Gemini Centre (SINTEF, NTNU) 2006, 2008-2013, . 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, and since 2021 in SFI PhysMet.
