ANDès, the French National Association for Doctors (PhDs), proposes a roundtable on sectoral mobility of Doctors in Europe. Created in 1970, ANDès mainly focuses on 3 missions: promoting the PhD by highlighting its added value, making PhDs' skills available for the whole society, and building a network to increase PhDs' visibility and promote their marketability. The PhD degree is originally dedicated to research, generating geographical mobility through research team partnerships, fellowships and career opportunities. However, PhD mobility is not only geographical, it is also disciplinary (via transferable skills promoted by the PhD) and sectoral (academy/industry, research/functions, business creation, etc...). Several programs exist to stimulate mobility during PhDs' careers, even so major variations can be observed across Europe. The proposed roundtable will focus on sector (private or public) and field (R&D or not) specificities, and their attractiveness for PhDs. The guest speakers will discuss the factors encouraging mobility and their influence on careers. Thus questions dealing with disciplinary and sectoral mobility will be addressed. For example, what makes positions more attractive, leading PhDs to switch their expertise field? How are seen PhD degrees accross European countries? What motivates a PhD to switch from industry to academy and vice versa during his/her career? How do Human Resources recognize the added value of a PhD, all along his/her career? Is mobility required to add value to PhDs after several years of experience? The speakers of this roundtable will be chosen to bring a European perspective on the topics described above, based on their own research or mobility. Moreover, during ESOF 2018, ANDès will also organise a one-day satellite event dedicated to all aspects of PhDs' mobility: this will be the third edition of the "Journée de la Communauté Française des Docteurs" (JCFD).
