Complexity Institute




Professor J. Stephen Lansing co-directs the Complexity Institute, as well as is the Faculty Associate Chair for Asian School of the Environment​ at Nanyang Technological University in Singapore. He is also an external professor at the Santa Fe Institute, birthplace of complexity theory, an emeritus professor of anthropology at the University of Arizona, and a senior research fellow at the Stockholm Resilience Centre. Before moving to Arizona in 1998, Lansing held joint appointments at the University of Michigan in the School of Natural Resources & Environment and the Department of Anthropology, and earlier chaired the anthropology department of the University of Southern California. In the 1980’s, Lansing and ecologist James Kremer showed that Balinese water temple networks can self-organize. Later research showed that over the centuries, water temple networks expanded to manage the ecology of rice terraces at the scale of whole watersheds.  In 2012, Bali’s water temple networks were recognized as a UNESCO World Heritage.  As the pieces of the water temple story were falling into place, Lansing became interested in self-organizing processes elsewhere in the archipelago. In 2000 he began to work with Indonesian geneticists, linguists and public health officials to study the co-evolution of social structure, language change and disease resistance on fourt​een Indonesian islands.

Professor​ Peter M. A Sloot is distinguished research professor at the University of Amsterdam and a full professor and co-director of the Complexity Institute in NTU, Singapore. He is a laureate of the Russian Leading Scientist president’s program and has been the PI of many international​ research programs on complex systems, like and He is editor in chief of two highly ranked Elsevier Science journals. He has published over 450 research papers. His work is covered in intern​ational media such as newspapers, interviews and documentaries. Peter sloot is also the Lead for the technology programme in Health Systems Complexity o​f the Nanyang Institute of Technology in Health and Medicine. ​See:​​

​​​​​Assoc Professor Cheong Siew Ann was born in Singapore in 1969. He studied physics at the National University of Singapore. He graduated in 1997 with a BSc (Hons) degree in physics, and obtained a PhD in theoretical condensed matter physics from Cornell University in 2006. He then spent a 1.5 year as a postdoctoral associate with the Cornell Theory Center, working on biological sequence segmentation, before joining the Nanyang Technological University as an Assistant Professor in Physics and Applied Physics in August 2007. His main research interest is in developing data analysis methods and toy models for understanding the dynamics of complex systems such as biological macromolecule​s, the brain, earthquakes, financial markets and infectious diseases. In particular, he works extensively with high-frequency, large-volume time series data, to cluster them, segment them, and also to estimate complex networks based on significant events in such data. His other research interests are in the areas ofcomputational physics and condensed matter physics.​
