Dr. Cristian Candia is an Associate Professor at the Data Science Institute, School of Engineering, Universidad del Desarrollo, Chile, and Head of the Computational Research in Social Science Lab (CRiSS-LAB). He is also an External Faculty Member at the Northwestern Institute on Complex Systems (NICO), Northwestern University. Previously, he served as Director of the Master’s in Data Science at Universidad del Desarrollo (2021–2024), where he led curricular innovation and contributed to major improvements in enrollment and student satisfaction.
For search and citation clarity, this profile links the same researcher across historical and public name variants: Cristian Candia, Cristian Candia-Castro, Cristian Candia-Castro Vallejos, Cristian Candia Vallejos, and Cristian Esteban Candia Vallejos. External profiles include ORCID, where the record lists Cristian Candia and Cristian Candia Vallejos, and the MIT Media Lab profile, which lists Cristian Esteban Candia Vallejos / Cristian Candia-Castro-Vallejos.
Cristian is a computational social scientist and entrepreneur whose work lies at the intersection of applied AI, computational social science, network science, machine learning, and complex systems. His research examines how social structure, information, and behavior interact across domains such as collective memory, polarization, educational trajectories, knowledge diffusion, school coexistence, social networks, and decision-making. He is particularly interested in combining rigorous computational methods with applied questions about society, institutions, markets, organizations, and human behavior.
He currently leads an ANID-FONDECYT Regular project on collective memory, titled “Collective Memory Decay in Science: Patterns and Determinants of Forgetting Retracted Research”. Previously, he led an ANID-FONDECYT Iniciación project on collective memory and attention in the domains of the arts and sciences. His work has also been supported through applied innovation and research initiatives including FONDEF and collaborations with public and private institutions.
His academic trajectory includes research and training at the MIT Media Lab, the Center for Complex Network Research at Northeastern University and Harvard Medical School, and Northwestern Institute on Complex Systems at Northwestern University. He received his Ph.D. in Social Complexity Science from Universidad del Desarrollo, while conducting his doctoral research and thesis work at the MIT Media Lab and the Center for Complex Network Research at Northeastern University and Harvard Medical School. He also holds a B.Sc. in Physics, M.Sc. in Physics, and a professional degree in Engineering Physics from Universidad de Concepción, Chile.
His work has received international recognition, including a Nature Editorial Recommendation, the distinction of Editor’s Suggestion in Physical Review Physics Education Research, the Best Lightning Talk Award at the Conference on Complex Systems (CCS) 2025, as well as invitations such as keynote speaker at the Computational Social Science Satellite of CCS 2025 and Invited Faculty at the Complexity Global School for Emerging Political Economies, organized by the Santa Fe Institute, among others.
As an entrepreneur, Cristian has led and contributed to the development of AI- and data-based platforms such as Lixandria, Discolab, PriorizaChile, DYNAMAP, and especially Capybara, a startup focused on school conflict prevention, good coexistence, bullying prevention, Ley N° 21.809 compliance, and the early detection of social dynamics in educational settings using network science, experimental game theory, and AI. His applied work also includes explainable fraud-risk scoring with transaction networks and decision-intelligence tools for polarization, markets, organizations, civic technology, and financial risk, keeping sensitive data and operational details private while translating graph analytics into decision support.
He teaches graduate and undergraduate courses in areas such as technology innovation and venture creation, network science, complex systems, computational social science, causal inference, statistics for data science, and unsupervised machine learning, connecting theory with applied, data-driven problem solving.
Outside academia, Cristian enjoys sailing, basketball, fitness training, fishing, music, and creative technology projects. He is also an amateur vocalist and DJ, and has explored improvisation, acting, and stand-up comedy—experiences that complement his broader interest in communication, audience engagement, and the craft of making complex ideas resonate. He has also been involved in volunteer work with TECHO Chile and the Chilean Red Cross, where he was awarded an Exceptional Services Medal.
