Federico Boem is a philosopher of science. He is a postdoctoral researcher, working with Yasemin J. Erden at the University of Twente. Within Nanobubbles, his main tasks include working on the explication of a common vocabulary in the research field, contributing to the building of bibliographical corpora, and the analysis and annotation of scientific literature.



Candida Sanchez Burmester is a PhD candidate at Maastricht University, in the field of Science and Technology Studies. In the NanoBubbles project, along with co-PI Cyrus Mody, she employs ethnographic and historical methods to analyse how claims and counter-claims have circulated at conferences in the field of nanobiology. 


Stefan Gaillard is a PhD candidate with a background in history & philosophy of science and cognitive psychology. He also has additional training in game theory and chemistry. His contribution to the project will be a qualitative social science study of two related controversies in nanobiology concerning the permeability of cell membranes and the blood/brain barrier to novel nanoparticles. He will be working with co-PI Willem Halffman at Radboud University (Nijmegen, Netherlands).




Guillaume Levrier is a postdoctoral researcher at LISIS. He holds a PhD in political science  from Sciences Po (CEVIPOF) and is specialized in studying the political epistemologies related to molecular biology. He is the creator and maintainer of the research software PANDORÆ.



Nathanne Rost is a postdoctoral student. Within NanoBubbles, she aims to investigate scientific papers based on critical overview, contributing especially in analyzing nanomaterials characterization data, looking forward to science self-correction. She will be working with Raphaël Lévy, within the LVTS laboratory at Université Sorbonne Paris Nord.



Maximilian Roßmann is a postdoctoral student based at the University of Maastricht. He holds a B.Sc. in chemical engineering and a Ph.D. in philosophy.  In the Nanobubbles project, Max conducts detailed case studies to trace how the promises of nanobiology emerged, were contested, and defy critical claims at conferences, in emerging research networks, and beyond. His particular interest is the role of narratives and the application of digital methods in the field of Science Technology Studies (STS).




Maud Bernisson is a postdoctoral student at the Institute for Science in Society at Radboud University (Netherlands) with a background in media and communication. Her role in the Nanobubbles project is to study controversies about error correction in the field of nanobiology and activists in this field.



Auste Valinciute is a postdoctoral researcher at the Institute for Science in Society at Radboud University (Nijmegen) with a background in science communication. Within NanoBubbles, Auste will be working on projects investigating epistemic activists and error correction practices in science.



Sanda Hachana is a research engineer who recently graduated from the Master’s degree in Natural Language Processing from the Université Grenoble-Alpes. Her role in the Nanobubbles project is to develop scripts for data collection to process and transform data collected from heterogenous corpus.



Wytske Hepkema is a PhD candidate with a background in molecular biology. She previously studied the role of journals in correcting and preventing scientific error. Within NanoBubbles, she will work at the Radboud University in Nijmegen, and will use a social science perspective to look at error, error correction, and overpromising.


Amira Barhoumi is a doctor in Computer Science with a background in Natural Language Processing (NLP). Within NanoBubbles project, she is a postdoctoral researcher, working at Université Grenoble-Alpes with Cyril Labbé, Frédérique Bordignon and François Portet. Her role is mainly to build datasets, models and tools using NLP techniques in order to analyse how scientific papers are cited, how claims appear in scientific records and are propagated.



Martin Lentschat is a Post-Doc Researcher in the Université Grenoble-Alpes. His PhD focused on the extraction of information in scientific papers and the representation of knowledge as n-Ary relations. Within the NanoBubbles project, he aims at designing a process to identify scientific claims published in articles and track how these claims are propagated and discussed in the literature.



Maha Said holds a Ph.D. in molecular and cellular Biology from Université Paris Saclay and has carried out research in Cancer Biology, Genetics, and Immunology. Maha is also interested in Science communication and has been an editor with an online platform that aims to simplify Cancer research for the general public. In the Nanobubbles project, Maha is a post-doctoral researcher based in Université Sorbonne Paris Nord who will work closely with the post-publication peer review team, and will be implicated in the replication project, during which she will utilize her experience in Biology to replicate selected experiments from articles published in the field of nanobiology.



Yagmur Ozturk is a PhD student at Université Grenoble-Alpes as a member of the Grenoble Informatics Laboratory. Her previous education comprises of translation studies, linguistics and natural language processing. In this project she will work on automatic detection of claims and counter-claims and critical citations in scholarly communication/social networks while exploring the language used in these contexts.


Mustafa El Gharib received his PhD in Chemistry and Bionanotechnology from the University of Hamburg, Germany where he then worked as a postdoc in the group of Wolfgang Parak. Mustafa is now part of  the Sorbonne Paris Nord University as a postdoctoral fellow to work on the replication project where he will utilize his experience in materials science, nanoparticle synthesis, characterization and their surface functionalization to help in the replication of some selected experiments that will form the basis of the replication project.



Mady Barbeitas is a veterinarian and sociologist trained in STS with a work experience in drug-development organizations. She is a postdoctoral researcher at LISIS (CNRS), working with Marianne Noël. In the Nanobubbles project, Mady investigates the epistemic activism and how concerns for correction of research claims emerge from researchers and research teams.
