It is all about Citations and how to count them. Citations to scientific papers are a major method to measure the impact of a scientist. Here at NIOO we use the ResearcherID to see the citations count, the graph showing the development over the years and the h-index. ResearcherID is based on Web of Science. * Google with Google Scholar as scientific database also calculates citations and h-indexes. You can easily make a profile and use this for your scientific branding!
