I’m a Senior Postdoc researcher and Lecturer at the Web Science and Social Computing Group in University Pompeu Fabra, Barcelona. I’m currently leading the DATALOG project funded by Fundació BitHabitat.
I obtained my PhD under the GEO-C Joint doctorate on GeoInformatics programme, funded by the European H2020 Marie Skłodowska-Curie Actions (H2020). My bachelor degree was in graphic and interaction design and hold a Master in Urban Studies. My work is focused on the study of the urban environment and the daily life in cities, approached from multiple disciplines such as Human and Cultural Geographies, Science and Technology Studies, Human-Computer Interaction, and Urban Studies. At my current position, Portela is exploring Machine Learning algorithms in practice, through different interfaces, including human oversight and algorithm-human interaction. I’m working towards more fair and explainable artificial intelligence implementations by making them interactive by design. Since 2022 I shifted back my research topic towards urban science and data governance studies.
Additionally, within the EU funded COST Action 15212 and with the private research-oriented company, Ideas for Change, I also collaborate in Citizen Science projects. Such projects consider laypeople in the process of generating new insights, research questions and data-driven decision-making. During 2019 to 2021 I’ve been working for the EU H2020 funded project ALOHA. During 2021 and 2022 I was hired as an external expert for the European Comission’s Joint Research Center contracted under the HUMAINT project.
I’m currently a Senior Postdoctoral Researcher leading the DATALOG project funded by Fundación BitHabitat and by the end of 2023 my position is funded by Maria de Maetzu program at the DTIC department.
I’m a contributing expert at the Cities Coalition for Digital Rights and a member of the Advisory Council on Artificial Intelligence for the Ajuntament de Barcelona.

PhD Thesis: Joint Doctorate in GeoInformatics
Geographies of Empathy: Affective reconfigurations of Cities, Objects & Places.
This work addresses the development of digital technologies from the perspective of corporeal and embodied encounters. It offers a critical view of the openness and smartness of cities, at the same time that propose a novel approach to create cities of equity, joy and delight.
It consist on a study of what becomes called Geographies of Empathy, as means of affective translations (Pedwell,2014). Empathy is presented as a process of ‘becoming together’, that takes place in forms of aesthetic experiences, collective conditions and structures of feelings (Anderson, 2014).
By presenting three interactive experiments and three explorations, it addresses the empathic relations that reify everyday practices. A focus on how mundane objects and urban places are experienced in encounters, provide an analysis on the mediation of affects, feelings and emotions.
The multidisciplinary approach in the process of research is performed by the application of concepts from Science and Technology Studies, Cultural Geography, Media Studies, Urban Studies and Human-Computer Interaction.
This work takes the form of a dialectical between the empirical/propositional and the theoretical/critique. By one side, it discusses the role of interaction design and the ethics and aesthetics of sociotechnical assemblages in cities. By the other, it addresses the political effects and consequences of empathic relations in the advent of urban development and the practices of designing urban interactions.

MSc Thesis: Urban Studies
Interfaces tecno-urbanas. Un análisis crítico sobre los retos socio-técnicos de las representaciones del espacio urbano.
Esta tesis recorre dos caminos convergentes en la historia moderna y su impacto en el desarrollo de la sociedad en las ciudades. Por un lado la creación de la cartografía como herramienta representativa y simbólica; y por otro el desarrollo de la tecnología digital y el software. Se parte de un análisis de la cartografía como elemento constructor de la historia de la sociedad occidental, abordada desde los Estudios Sociales de la Tecnología. Posteriormente, se aborda la cartografía como objeto constituyente de la modernidad desde el análisis semiótico, esquematizando su capacidad comunicacional, ética y estética.
La segunda parte recopila los principales argumentos en torno a la relación entre tecnología y espacio urbano; por el otro, se abordan los debates de la cartografía contemporánea y digital en torno a los procesos urbanos, para ello estudiamos un caso local.
Como conclusión, la especialización de múltiples disciplinas convergen en el desarrollo de soluciones para un mundo altamente urbanizado. La utilidad de las representaciones urbanas está en considerarlas como constructores en las relaciones de poder, posible gracias a las oportunidades que la tecnología aporta. Y que a su vez, permite el estudio de fenómenos sociales que constituyen nuevas teorías sociales, manteniendo la complejidad y las controversias que se dan en los espacios urbanos.
