NERCCS 2026: The Ninth Northeast Regional Conference on Complex Systems will follow the success of the previous NERCCS conferences to promote the emerging venue of interdisciplinary scholarly exchange for complex systems researchers in the Northeast U.S. region (and beyond) to share their research outcomes through presentations and online publications, network with their peers, and promote interdisciplinary collaboration and the growth of the research community.

NERCCS will particularly focus on facilitating the professional growth of early career faculty, postdocs, and students in the region who will likely play a leading role in the field of complex systems science and engineering in the coming years.

The 2026 conference will be held primarily in person at the University of Rochester, with an online participation option via Zoom.

Workshop on Complex Network Analysis with Applications in Brain Network Science and Complex Systems aims to bring together academicians, researchers, industrial experts, Ph.D. scholars, and postdoctoral fellows to explore recent advancements and foundational concepts in the fields of graph theory and its applications in network analysis. Graph theory, a cornerstone of discrete mathematics, offers a robust framework for modeling and analyzing complex networks across various domains from biological systems and brain connectivity to social, technological, and infrastructural networks.The primary aim of this five-day workshop is to provide a comprehensive introduction to the mathematical foundations and computational techniques in complex network analysis, with a particular emphasis on its applications in brain network science and biomedical data analysis. The program will cover a range of contemporary topics, including the simplicial analysis of fMRI data to study human brain dynamics during functional cognitive tasks, analysis of complex networks and prediction using deep learning models, and exploration of graph algorithms along with their computational complexity. Participants will also gain exposure to advanced methodologies such as the application of complex networks in machine learning, the characterization of resting-state fMRI for brain connectivity analysis, and diffusion MRI analysis for clinical applications. In addition, the workshop will introduce recurrence network analysis, which is used to predict climate changes and other dynamic systems. To complement these theoretical discussions, hands-on sessions will be conducted on complex network analysis using NetworkX, and nonlinear dynamics in recurrence relations.

The number of scientists working on networks and complex systems in the Asia-Pacific region is increasing, but high-level conferences in these areas remain limited to NetSci, NetSciX, the International Conference on Computational Science (ICCS), and Conference on Complex Systems (CCS). Asia-Pacific scientists, especially postdocs and PhD students in these areas therefore have limited opportunities to attend these conferences. This leads to a lack of exposure of Asia-Pacific scientists to good work done elsewhere in the world, and of scientists from other parts of the world to good work done in Asia-Pacific, and seriously hampers the academic growths of Asia-Pacific scientists. Recently, we have been encouraged by the strong turnout of Indian scientists at all levels at the NetSciX 2025 conference in Indore, India. We can sense that the younger scientists treasured this opportunity to share their work. Unfortunately, it is impossible to bring these flagship conferences to Asia-Pacific every year. At best, we can host one such conference in Asia once every three to four years.

This prompted us to start an Asia-Pacific Conference on Networks and Complex Systems beginning next year (2-5 Jun 2026 in Singapore) to cater to these unmet demands. With this conference, we would always have a platform to present our recent work and meet up with colleagues. While we will always invite the most exciting speakers from all around the world, our goal is to include more invited speakers from Asia-Pacific. We also aim to give as many participants as possible (including PhD students) a chance to give oral presentations. We will rotate this conference series around Asia-Pacific, where most venues are more affordable compared to Europe or North America. Hopefully, more Asian scientists would be able to attend, even if they have limited funding. This is especially true of PhD students and postdoctoral researchers, many of whom can only attend the local editions of the conference.

Finally, to ensure that the conference is relevant and high-level, we will be advised by an International Advisory Committee of eminent scientists in the fields of networks and complex systems. Additionally, to ensure that good organizational practices are shared after they are developed, besides local organizers the organizing team for a given year will also comprise core members from the organizing team for the next year.

The 2026 Conference on Complex Systems will be held in Binghamton, New York, USA. Binghamton has a long history of creativity and innovation. The Greater Binghamton area has historically been called “the Valley of Opportunity” and attracted many immigrants (especially from Europe) since the mid-1800s, which has made the region’s rich and diverse culture and demographics. It is the birthplace of IBM (International Business Machines), Link Flight Simulator, McIntosh Laboratory, and a number of other pioneering ventures, fostering a spirit of ingenuity that continues to thrive.

Located at the confluence of the Susquehanna river (one of the oldest rivers in the world) and the Chenango river, the region boasts stunning natural beauty and offers ample opportunities for outdoor recreation, from hiking and biking to fishing and kayaking. In particular, in mid-October when CCS 2026 is held, the Binghamton area will showcase its renowned and breathtaking fall foliage. Furthermore, a vibrant arts and culture scene flourishes here, with numerous galleries, theaters, and music venues providing enriching experiences.

CCS 2026 will be held primarily in person on the main campus at Binghamton University, with an online participation option via Zoom.

The Spanish Society of Complex Systems (CS³ Spain) was founded in 2022, during the International Conference on Complex Systems held in Palma de Mallorca, with the aim of strengthening the community of complex systems researchers in our country.

Since then, the Spanish Chapter has held three meetings: in Santander (2023), in Barcelona (2024) and in Madrid (2025), consolidating itself as a reference space for the exchange of ideas and interdisciplinary collaboration.

The 4th Meeting of the Spanish Society of Complex Systems will take place in Seville, from January 21 to 23, 2026, at the emblematic Uruguay Pavilion, headquarters of the University of Seville.
