Virtual Participation

BIDS GraphXD banner logoOn March 23, 2021, 10:00–3:00 PM Pacific, BIDS GraphXD 2021 convened data science experts from a variety of fields to promote interdisciplinary collaboration and training for researchers, scientists, and theorists interested in using graphs and network analysis for applications across domains. This year’s program featured presentations from distinguished speakers and tutorials focused on NetworkX, the fundamental network analysis tool for creating and manipulating graphs and networks in Python. Presentations and tutorials highlighted this framework’s utility and diversity in a variety of applications. All researchers, scientists, and theorists interested in using graphs and network analysis were welcome and encouraged to attend this event.  Watch the BIDS GraphXD 2021 presentation and tutorial videos on YouTube.


This event will be presented on the platform Discord, an open access virtual platform to encourage ongoing participation and engagement across a global community of researchers. Participants can engage with this platform at any time to chat with colleagues and to build research collaborations. First, sign into the BIDS XD Community on Discord. If you’re new to the BIDS XD Community or the Discord platform, we encourage you to take a few minutes to sign in to get acclimated in the days leading up to the event. Then, on March 23, participants may explore the GraphXD “channels” and participate in a variety of ways:

BIDS GraphXD (Graphs Across Domains) is a cross-domain initiative that promotes interdisciplinary collaboration and training for researchers, scientists, and theorists interested in using graphs and network analysis for applications in a variety of fields across STEAM including (but not limited to) anthropology, art, biology, computer science, economics, history, linguistics, mathematics, physics, and sociology. To get more involved in the BIDS XD community online, sign up for the BIDS XD Community on Discord.


Laura K. Nelson

BIDS Alum – Data Science Fellow

Former BIDS Data Science Fellow Laura K. Nelson is an Assistant Professor of Sociology in the College of Social Sciences and Humanities at Northeastern University. Laura uses computational methods and open source tools - principally automated text analysis - to study social movements, culture, gender, institutions, and organizations. She is particularly interested in developing computational tools that can bolster the way social scientists do inductive and theory-driven research. She received her PhD in sociology from the University of California, Berkeley, and she also holds an MA from UC Berkeley and a BA from the University of Wisconsin, Madison. While at UC Berkeley, she was a postdoctoral fellow with Digital Humanities @ Berkeley, developing a course for undergraduates on computational text analysis in the humanities and social sciences. 

Lauren Ponisio

BIDS Alum - Data Science Fellow

Lauren Ponisio was a postdoctoral scholar in the Environmental Science, Policy, and Management department and a BIDS Data Science Fellow. She is currently an Assistant Professor at UC Riverside, where the Ponisio Lab studies the mechanisms operating in complex ecological communities in order to restore biodiversity in degraded ecosystems.

As a native of the Central Valley, Lauren has a personal connection to issues concerning the sustainability of agriculture, and a primary goal of my research is to make agricultural systems better for humans and wildlife. She thus also investigate strategies for designing agricultural systems to promote biodiversity conservation and the links between conservation strategies and improving livelihoods.

Lastly, she is working on the development team of NIMBLE, a system for building and sharing analysis methods for statistical models, especially for hierarchical models and computationally intensive methods. Statistics is the primary way scientists identify patterns within their data, and thus, advances in fields applying statistics are often facilitated by computational methods.

Niek Veldhuis is Professor of Assyriology (cuneiform studies) in the Department of Near Eastern Studies. He received his PhD at the Rijksuniversiteit Groningen (The Netherlands) in 1997, and came to Berkeley in 2002. His primary interests are in the intellectual history of ancient Mesopotamia (History of the Mesopotamian Lexical Tradition, 2014) and Sumerian literature (Religion, Literature and Scholarship: The Sumerian Composition Nanše and the Birds, 2004).  He is director of the NEH-supported Digital Corpus of Cuneiform Lexical Texts and is a member of the international Oracc Steering Committee, providing tools and standards for digital publication of cuneiform texts to scholars worldwide. Today, his main research focus is on developing computational text analysis scripts (primarily in Jupyter Notebooks) for cuneiform datasets.

Douglas Guilbeault

Assistant Professor, Management of Organizations, Haas School of Business, UC Berkeley

Douglas Guilbeault is an Assistant Professor in the Management of Organizations Group at the Haas School of Business. He studies how people learn, challenge, develop, and invent categories by communicating in social networks. This investigation extends to the analysis of how organizations mediate and augment social computation by enabling new forms of communication, coordination, and creativity. This investigation further extends into how the social construction of meaning can be shaped by various sources of influence, such as political messaging and the design of social media platforms. His work on these topics has appeared in a number of journals, including Nature Communications, The Proceedings of the National Academy of the Sciences, Cognition, Policy and Internet, and The Journal of International Affairs, as well as in popular news outlets, such as The Atlantic and Wired. Guilbeault’s work has received top research awards from The International Conference on Computational Social Science, The Cognitive Science Society, and The International Communication Association. In addition, he was a recipient of Stanford’s “The Art of Science” award for the piece “Changing Views in Data Science over 50 Years” produced in collaboration with the research collective, comp-syn. Guilbeault teaches People Analytics at Haas, focusing on how organizations are using novel algorithmic methods to address (and sometimes inadvertently create) fundamental problems in management.
