The success of each blog rises and falls with its content. Key to “Innovation4E” is therefore the blogger: colleagues and scientists, namely experts, who work daily in their fields of expertise – not from the stands but right in the thick of it. The bloggers give a firsthand account of the most innovative, exciting, extraordinary and state-of-the-art information in their field.
Behind each blogger there is a person with an interesting history that has made him or her the expert they are. Here we introduce you to our bloggers:
