Dr. Raphaël Stephens is a post-doctoral researcher at LISIS (Université Gustave Eiffel ) since January 2021. A Doctor in Social Sciences from AgroParisTech, ABIES Doctoral School (Agriculture, Food, Biology, Environment, Health), he prepared his doctoral thesis, focussed on agri-food provision regime transitions in metropolitan contexts, at UMR LISIS under the supervision of Marc Barbier, and defended his thesis in January 2020. His doctoral research dealt with food transitions, and more particularly with transitions that aim to shorten food provisioning (especially Alternative Food Networks and short food supply chains), as well as transitions that are linked to the digital economy. This research was carried out within the broader context of sociotechnical regime transitions and interactions between innovative niches and regimes. His research has also led him to study prosumption and new forms of market and non-market intermediation and participation. His profile and research are interdisciplinary, and mobilise concepts and methodologies from sociology, geography, and urban planning. His methodologies are both quantitative (analysis of digital data traces, lexicometrics) and qualitative (interviews and questionnaires, ethnography, documentation analysis). In particular, he mobilizes CorText.Manager and Iramuteq as analytical tools. Raphaël previously worked five years in the financial sector in export, project, PPP and tax-lease finance, in regulatory risk management and in microfinance. He holds degrees in urban planning and geography from University College London (MSc International Planning; BA Geography), and in management from Audencia Nantes Business School (MSc in International Management with finance specialism). He comes from an international background, has lived in the United Kingdom and Mexico, and speaks five languages fluently (French, English, Spanish, Portuguese, German).
