Marc Santolini

Team Leader

I am a long-term research fellow at CRI Paris and visiting researcher at the Network Science Institute in Boston. I am also the co-founder of Just One Giant Lab, a nonprofit initiative aimed at developing decentralized open science using smart digital tools. I majored in theoretical Physics and minored in philosophy of science at ENS, Paris. I followed up with a PhD in the Statistical Physics Department of ENS investigating gene regulatory networks using tools from physics and machine learning. During my postdoc at the BarabasiLab of Northeastern University and the Division of Network Medicine at Harvard Medical School, I have investigated the networks underlying biological systems at all scales, from network medicine (protein interactome analysis) and personalized medicine to hospital network analysis, to the making of biology by studying the iGEM competition, an international student competition of synthetic biology. Since my arrival at CRI Paris, I have been studying collaborative learning and solving using network approaches on large empirical datasets, with the end goal to develop tools fostering collective intelligence for social impact. Apart from the lab, I enjoy playing music (all sorts of guitars and world percussions) and exploring the bottomless pit of weirdness that is the internet (Ben Levin, Bill Wurtz…).

Raphaël Tackx

Post-Doctoral Researcher

I am currently a postdoctoral fellow in network science and data science. My background is in computer science and during my PhD, I focused on graph theory and its application to social network analysis. In particular, I studied the structure of bipartite networks and developed algorithms to exhibit their community structure. Using these tools I studied how individuals organize into communities on platforms such as Wikipedia, Meetup or Yelp. I am now developing applications that will collect various types of data coming from students participating to the iGEM competition. For instance, I developed CoSo, a smartphone application that can capture physical and social interactions between team members by using bluetooth as a sensor.

Rathin Jeyaram

Research Engineer

I majored in Theoretical Computer Science and graduated in June 2020. I am interested in everything graphs and networks, particularly on how network models explain social and biological phenomena. I am now working on the iGEM Ties project – studying interactions within and amongst iGEM teams and analyse how that influences collaboration, learning, success and hypothesize what drives those interactions in the first place. Aspiring to pursue a PhD past my graduation, broadly in network data science and I am looking to explore possibilities and develop skills for a career in research. On a lighter note, I enjoy long walks, latin music and football.

Chakresh Singh

Post-Doctoral Researcher

I work in the field of complex networks. I am also interested in problems related to non-linear dynamics, agent-based modelling of complex systems and recently I have a newfound interest in looking for machine learning applications in the field of network science. I completed my Masters in Physics in 2014 (IIT-Kanpur) and defended my PhD. thesis in 2020. During my doctoral thesis I used networks based approach to understand the structure and dynamics of collaboration between Indian researchers. The data was extracted for a period between 1919-2013 from publications by Indians in American Physical Society (APS) journals. At CRI, I am working with Marc Santolini and Liubov Tupikina on using large scale data sets and physics inspired approaches to understand innovation and collaboration in science and technology.

Lionel Deveaux

Digital Research Projects Manager

Lionel Deveaux is a digital project manager at CRI, Paris. His main role is to facilitate IT projects for research, and does so here by coordinating the development and maintenance of the digital apps produced in the team.

Camille Masselot

Research Assistant

Camille holds a Masters’ degree in Public Health (MPH) from the Bordeaux School of Public Health with a specialization in international health. Her professional experience includes operations research on health systems mostly in Sub-Saharan Africa, and public health program management in collaboration with a wide range of stakeholders. More recently, she has been leading the operations of the NGO Just One Giant Lab (JOGL) and its platform, fostering the collaboration of a +4000 online volunteer community worldwide, composed of researchers, students, and entrepreneurs to undertake research and innovation projects on immunization and now COVID-19 within an open science framework. Globally, her professional interests lie in the resolution of global health issues in low-resource settings related to universal health coverage, implementation research, governance and participatory approach, and complex systems analysis. She is also a strong advocate of open science.

Samuel Fraiberger

Data Scientist at World Bank, NYU, MIT Media Lab

I am a computational social scientist fascinated by how the digitization of our lives allows to study social processes at an unprecedented scale, using massive datasets and methods borrowed from computer science and social sciences. I am fortunate to have published my latest research in Science and presented it at TEDx. I am also a firm believer in the power of data and technology to solve societal challenges.

Michael Rera

CRI Core Research Fellow

I am a CNRS researcher with a core fellow position and CRI. I majored in Genetics in former Université Paris Diderot and followed up with a PhD studying Biology of ageing on the model organism Drosophila melanogaster, investigating the role of mitochondria in the process of natural ageing. During my postdoc in the Walker lab of UCLA, I furthered my study of mitochondria and their role in Drosophila’s digestive tract ageing. Since my recruitment as a CNRS researcher in 2013, I have built upon the first phenotype allowing to predicting impending death (Smurf phenotype) that I described during my postdoc, proposing a new theoretical framework for studying ageing – the two phase model (2PAC) –, showing its broad evolutionary conservation and proposing a novel mathematical model for describing population longevity. My arrival at CRI Paris marks the inclusion of synthetic biology and network theory in my projects.
