Euranova x ACM DEBS 2021

Speaker: Maryse Colson
Bio: Maryse Colson is the Mary Poppins of Euranova (Brussels, BE), taking care of people, fixing tactical communication issues, and doing her magic from time to time. She has a PhD in French Literature; her thesis was about The Genesis of the Cookbook: Discursive Study of the Culinary Publications in the Ancien Regime (Université de Liège, 2014) and she uses her literary skills for the benefit of a staff of passionate data experts and their management team.


Speaker: Sebastian Frischbier
Bio: For Sebastian, this year's DEBS conference is marking a full decade of affiliation with the DEBS community: his first time at a DEBS conference had been in 2011 (DEBS New York, US) as a PhD candidate under the supervision of Alejandro Buchmann (and later, also Peter Pietzuch). He received his PhD on runtime support for quality of information requirements in event-based systems from TU Darmstadt before re-joining industry in various leadership positions.
In his current role at Infront, Sebastian is fostering transparency, simplification, and automation regarding, systems, processes, and roles across the Infront group. While this might sound to be completely detached from his former areas of interest it is actually the direct application of his research, as Infront is doing event-processing at scale for a living. He is also still actively engaging in joint research activities and looking for interesting collaboration topics between industry and academia.
Please do not hesitate to get in touch with Sebastian (e.g., via the DEBS 2021 Slack channels) regarding collaboration opportunities or career options at Infront -- there might be more topics of mutual interest than you think.
