Eddie Lee

Eddie studies the role of information in the small and large living patterns around us. Examples range from the biology of neural tissue to the ecology of forests, the dynamics of armed conflict, and the processes of innovation and obsolescence in society. He is fascinated by how we paint those patterns on the shared canvas of mathematics and what the resulting similarities between the mathematical representations reveal about them. Do similarities reflect analogous function, universal dynamics, or are they (simply) artifacts of our representation? His work aims to answer these overarching questions that come together from the standpoint of information.

He is an Austrian Science Fund ESPRIT Fellow at the Complexity Science Hub and formerly a Program Postdoctoral Fellow at the Santa Fe Institute. He has a PhD in Theoretical Physics from Cornell University—where he received a National Science Foundation Graduate Research Fellowship—and a BA in Physics from Princeton University. He has been invited to panels on the science of violence (Santa Fe Council on Int’l Relations) and on the physics of the 2021 Nobel Prize (Santa Fe Institute) as well as lectures at the universities of Amsterdam, Potsdam, Northwestern, Oxford, and Bristol.

Niraj Kushwaha

Niraj joined the Complexity Science Hub Vienna as a Ph.D. candidate in August 2021. He has a masters in physics from the Indian Institute of Technology Indore. His master’s thesis was in the field of non-linear dynamics and complex networks.

For his masters’ thesis, Niraj performed network modeling using Kuramoto’s oscillators to study collective behavior found in many real-world systems and also studied critical transitions between synchronization and chimera (solitary) states found in dynamical networked systems. In order to study the phase space of such systems, he used a unique technique that used machine learning to draw boundaries between the different phases.

Niraj’s research interest lies at the intersection of statistical physics, collective behavior, network science, computational modeling, data analysis and machine learning. Through his research, he wishes to study the hidden universal laws of nature, using various tools and techniques that fall under the umbrella of complexity science.

Currently at the Hub, Niraj is building a systematic framework to study armed conflicts and also studying various emergent regularities that are found in armed conflicts.

Ernesto Ortega

Ernesto is currently a PhD candidate at Havana University. His current research is based on the study of epidemic processes in complex networks. In 2023 he will join the Complexity Science Hub Vienna as a postdoc researching in the field of complex systems and collective behavior with particular focus on evolutionary systems driven by innovation and obsolescence processes.
