Bruhn, Thomas
is a physicist (PhD) working transdisciplinarily at the IASS Potsdam since 2012. His key ambition is to contribute to a changing awareness for sustainable human relations within the Earth System in the Anthropocene.
In the first years at the IASS his research focused on technological topics like climate engineering and the environmental impacts of technologies for utilizing CO2 as a resource (carbon capture and utilization). Since 2016 he is leading the research group AMA (A Mindset for the Anthropocene) on the question how the transformation of mental paradigms and specific qualities like mindfulness and compassion can be integrated into processes for sustainability. Since 2017, he is also working in the team Co-Creation & Contemporary Policy Advice that aims at investigating and designing co-creative processes in the realm of political decision making for coping with wicked problems in the context of sustainability.

Before joining the IASS he did research on semiconductor nanomaterials in Berlin, Rome and Marseille. Beside his research work he is also a trained facilitator and is active in several NGOs, i.e. as a member of the executive board of the German Chapter to the Club of Rome or the German Association of Scientists (VDW).

There she undertook research on sea-level rise impacts, sustainability and governance of coastal areas and gained substantive experience in interdisciplinary research and teaching. Her interest in the climate change and ocean nexus has recently gained traction through a H2020 research project on ocean-based net emission technologies, OceanNETs, where she is involved as principal investigator on ocean-governance. In her current work she further addresses specific issues relating to the implementation of Sustainable Development Goal (SDG) 14, the “ocean goal”, such as how to enhance collaborative processes at the science-policy-society interface.

Niestroy, Ingeborg
is a geographer, worked as planner for transport projects, and has ever since been interested in governance questions of environmental integration and sustainable development. In her Ph.D. thesis she described decision-making processes with Strategic Environmental Assessment with a special focus ofplanning processes for waterways (river Elbe) and dredged material disposal (San Francisco Bay).
She has some 20 years of experience in the science-policy-society interface of the sustainable development arena, both as apractitioner and researcher. sShe worked at EU level, in European and international cooperations as well asinter alia as director of EEAC, the European network of advisory councils for environmental policy and sustainable development, in the European Economic and Social Committee (EESC), in the civil society alliance SDG Watch Europe and the European Commission's multi-stakeholder platform on Agenda 2030.
