Our Team

It’s (also) all about team-work. The three of us, Stavros, Vassilis and Nassos,  we know each other for more than a decade. We have worked together in between either during our PhDs and/or as post-doctoral researchers, or for product development. We have more than 10 years of working and research experience in either EU, Greek national, US funded projects, and more than 70 publications in peer reviewed scientific international journals and top research conferences, where we also offer our services as peer reviewers.  We had partners in research projects across several universities, and institutions. We consider the chemistry between all team members  to be a natural ingredient that composes  an inspiring collaborative working environment; this is the vehicle for succesfull work in both industrial and scientific challenging frameworks.
