The thesis spans 5 papers that advance data and network analysis of bicycle infrastructure, from the 3 perspectives of 1) data foundations, 2) spatial patterns of bikeability, 3) linking research and planning. Unique achievements are the analysis of a whole country’s (Denmark’s) bicycle infrastructure and network, with the creation of open source tools. The thesis also concludes a project funded by the Danish Ministry of Transport / Road Directorate.

In her research Ane reveals that bicycle infrastructure data often suffer from inconsistencies and low quality, reflecting historical underinvestment in active mobility data. This data heterogeneity creates an information gap and necessitates extensive preprocessing, creating barriers to cycling research and planning. Additionally, she finds that bikeability and access to low-stress cycling infrastructure are highly spatially clustered, with substantial disparities between urban and rural areas. While urban areas generally benefit from better cycling conditions, large segments of the Danish population are deprived of the advantages of active mobility. The geographical differences in bicycle infrastructure access and data quality highlight the need for a spatial perspective in cycling research. Finally, she demonstrates that data-driven tools can aid bicycle planning by generating insights into complex planning questions that involve large geographical areas.

With her PhD completed, Ane has already started a research position at Roskilde University, where she remains at least for the short term. We are both sad to “lose” Ane with her friendly, collegial spirit and unreplaceable skill set, and happy for her success and positive impact in the world. That being said, we are not finished collaborating, and will always be happy to see Ane around.

Anastassia defends her PhD: Urban Data Science for Sustainable Mobility

Big congratulations to Dr. Anastassia Vybornova – she defended her thesis yesterday, on Urban Data Science for Sustainable Mobility! 🥳 🎓 This makes Anastassia the first PhD student who did their whole PhD journey at NERDS – about which we are especially proud, besides her brilliant scientific accomplishments.

Supervisor: Michael Szell
Committee: Luca Rossi, Malene Freudendal-Pedersen, Robin Lovelace

Read her thesis here: https://en.itu.dk/Research/PhD-Programme/PhD-Defences/PhD-Defences-2025/March/Anastassia-Vybornova

The thesis spans 8 papers that advance Urban Data Science, exploring how this emerging field can ethically support human mobility that is both environmentally and socially sustainable, through the two lenses of Data and Networks.

In her research she develops algorithms and pipelines for multi-purpose spatial network simplification, for data quality assessment and planning of bicycle networks and low-traffic neighborhoods, showcasing applications to various cities. Further, she outlines pathways for incorporating data ethics into computational approaches to spatial manifestations of social inequalities. Lastly, she investigates the impact of transportation infrastructure on social connections in cities, quantitatively corroborating that urban highways are barriers to social ties. Stemming from various interdisciplinary collaborations, the results of this thesis cover multiple conceptual levels of Urban Data Science, from open source software development and data quality assessment to transportation network planning and the intersection of social and spatial networks. Through these efforts, this thesis advances the emerging field of Urban Data Science, showcasing the field’s potential to make human mobility more sustainable.

With her PhD completed, Anastassia starts a postdoc position at SODAS with Roberta Sinatra, retaining a visiting affiliation at NERDS. Anastassia has been both a professional and social cornerstone of NERDS, so we are lucky we will keep seeing her around. 💜

Jonas wins Novo Nordisk Data Science Investigator Grant!

As reported today on ITU’s frontpage, our newest NERDS faculty member, Jonas Juul, has just won a Novo Nordisk Foundation Data Science Investigator grant of DKK 6.5 million (~EUR 870,000) for a project to improve statistical methods for predicting outbreaks of infections. Congratulations Jonas, we are so happy for you and your great start at NERDS/ITU! 🥳

The project InForM: Inference, Forecasting, and Mitigation of future pandemics runs for five years. It is a collaboration between the IT University of Copenhagen, Statistics Denmark and The State Serum Institute, where Jonas has already collaborated successfully.

It consists of three different parts. The first part is about improving statistical methods that are used for predicting how diseases spread, the second part is looking into which methods for prevention and control of disease are more efficient in what situations, and the third part is about figuring out how COVID-19 spread during the pandemic. Read more in the ITU news.

Winning such a prestigious grant as an assistant Professor is in itself an achievement, but we as NERDS are even more so happy for finally convincing also Novo Nordisk Foundation as the last “missing” major Danish grant agency to fund us. We applaud Novo for their decision – Jonas’ excellent health-related know-how is turning into a boost for epidemiological research in Denmark.

Jonas’ InForM project will soon open calls for PhDs/Postdocs.. stay tuned!

Carlson Büth wins VCD Award for his Master thesis

Carlson Moses Büth, who visited us last year from University of Münster, Germany, won the VCD Award (1st place Special Award) for his master thesis

From Gridlocks to Greenways: Analyzing the Network Effects of Computationally Generated Low Traffic Neighborhoods

that he wrote at ITU, co-supervised by Anastassia+Michael@NERDS. We congratulate Carlson to this achievement! 🎉


Photos from the VCD Award Ceremony by Jan Zappner

The VCD is the “Verkehrsclub Deutschland”, a major non-profit association and traffic club in Germany that is committed to a socially and environmentally friendly transport transition towards mobility for all road users.

Over the course of his master thesis Carlson also initiated the development of the Python package superblockify which we published recently within the JUST STREETS EU Horizon project we are part of. See: superblockify.city, its Github repository, and the accompanying paper at JOSS.

NERDS at ASONAM’24

A bunch of nerds posing in front of the asonam conference logoLuigi Arminio wins the asonam best phd dissertation award

NERDS’ summer sheneanigans continue at ASONAM, in the beautiful and sunny Calabria. Lucio La Cava and Alessia Galdeman held a tutorial on Mining, Modeling, and Analyzing Decentralized Social Media. Alessia Antelmi organized the HyperSci workshop on Theory and Applications of Hypernetwork Science. Luigi Arminio and Daniele De Vinco presented at the PhD Forum. Luca Aiello fulfilled his duties as the conference Program Chair. Luigi won the prize for the best PhD forum contribution!

5 years of NERDS!

NERDS was founded 5 years ago by three young assistant professors and one associate professor, to be a reference point at ITU for the research on network and data science applications to social systems. At 5 years old, we have learned to write our name (we have a logo), to follow rules, and to use a fork and knife for eating. And hoo boy, did we use that fork last friday when celebrating our anniversary with an original NERDS cake!

We also got new group photos taken (by Sebastian Mateos Nicolajsen – thx!), see below, because we have grown to 20+ members over the years! For all bean counting aficionados, we also won over 5M EUR of research funding and published 84 papers so far.

Further highlights, shown in the timeline above. We:

Looking back to our goals 5 years ago, we have all reason to be proud to have 1) built up a flourishing network of Denmark-based network/data science research groups, connecting ITU, KU, DTU, and others, 2) successfully impressed several funding agencies and public stakeholders to engage with us solving societal problems with our research. We will continue along this road, developing further our group in a safe and fun environment.

In our near future, we look forward to welcoming several new group members in the fall, including one assistant professor and several PhDs/Postdocs.

Live long and prosper 🖖

GrowBike.Net covered in Austrian media

Our project GrowBike.Net was just covered in Austrian media, both in an online news report and on Austrian TV station ORF 2, in the news report Wien heute. If you understand German, watch our 15 seconds of fame here: https://tvthek.orf.at/profile/Wien-heute/70018/Wien-heute-vom-27-03-2024/14219951/Radinfrastruktur-ausbaufaehig/15608017

The written report Radwege sollen möglichst direkt verlaufen: https://wien.orf.at/stories/3249925/

GrowBike.Net is an interactive platform resulting from an ITU master project, visualizing the results of our 2022 paper Growing urban bicycle networks: https://www.nature.com/articles/s41598-022-10783-y. The idea is to simulate the creation of a cohesive bicycle network inspired by the Dutch CROW design manual for bicycle traffic. Studying these synthetic networks informs us about the geometric limitations of urban bicycle network growth and can lead to better designed bicycle infrastructure in cities. In the case of the Austrian news report, the key metric of directness was highlighted: Bicycle networks should allow for direct paths without substantial detours.

Michael Szell wins EU Horizon grant

As one of 32 partners, Michael Szell / ITU is part of the EU (Horizon) project

JUST STREETS – Mobility justice for all: framing safer, healthier and happier streets

that has just started! The consortium includes 12 European cities representing more than 4.5 million citizens. The project aims to transform cities’ car-centered mobility narratives that take for granted that streets are for motorized traffic only, to promote walking, cycling and other active modes of mobility.

To reach this goal, ITU’s part of the project will develop algorithmic methods to study low traffic neighborhoods and bicycle/pedestrian networks, and analyze mobility data with focus on safety, for better planning of human-centric, sustainable mobility.

This grant will provide us funding for a new PhD student, Clément Sebastiao, who has recently joined our group.
