Dr. Tatiana González Grandon is the Associate Academic Officer of Energy at the United Nations University in Bonn. Additionally, she holds the position of Senior Researcher at the Norwegian University of Science and Technology (NTNU). Dr. González Grandon earned her PhD in applied mathematics from Humboldt University Berlin, supported by a DFG excellence scholarship from the Berlin Mathematics Research Center MATH+. Her primary research expertise lies in stochastic optimization and forecasting time series. Her research focuses on utilizing such mathematical approaches for informing climate mitigation policies or just transformations within energy and water infrastructures.

To avoid data-centric epistemologies, as a mathematician, Tatiana enjoys collaborating with human geographers, political economists, and social anthropologists for the analysis of underlying power relationships, socio-ecological inequalities, and possible decolonial transformations to foster just transformations in the Global South.

At IRI THEsys, she is a co-supervisor of two PhD students of the W4W project who are applying machine learning algorithms for future hydrological prediction of selected dams in Colombia. Her research project in W4W delves into the predictive historical modeling of revenue streams for four hydropower plants in Colombia. Leveraging historical meteorological data, market prices, and a novel stochastic dispatch model developed for this study, she aims to forecast the financial performance of these energy assets. The primary objective is to contrast these revenue past projections with the taxes paid by multinational-owned hydropower plants in Colombia, raising important transparency-related questions within the context of privatization of the energy sector. Moreover, collaborating with fellow researchers in an interdisciplinary approach, she will examine the impact of hydropower plant schedules in Colombia, driven by market logic and technocratic approaches, on the daily lives and livelihoods of local communities. The research will specifically focus on unraveling the temporal harmonies or conflicts between community rhythms and agricultural processes, contrasting them with the regimented schedules imposed by hydropower plants.

She is a member of the Energy Research and Decolonial Working Groups.
