1st Talk | Towards Responsible Visual Analytics: Fostering Inclusivity, Accessibility and Trustworthiness in the AI Era  

Held by: Ali Sarvghad, University of Massachusetts, Amherst

Abstract:

As data visualizations play an increasingly pivotal role in shaping decisions across personal, public, and scientific domains, ensuring their ethical, inclusive, and accessible design has become more crucial than ever. My work, driven by the growing role of visualizations in decision-making and the integration of AI in the data analysis pipeline, delves into the ethical and responsible dimensions of data visualization. In this talk, I explore the convergence of theory and emerging technologies in advancing responsible visual analytics. Through examples from my research, I will illustrate how understanding graphical perception across diverse audiences, such as older adults, utilizing conversational agents to enhance data collection, and applying differential privacy to safeguard individual privacy fosters inclusion and trust throughout the data lifecycle—from collection and analysis to insight discovery and decision-making. Through real-world applications and empirical research insights, this talk invites a critical rethinking of the ethical responsibilities of visual analytics and proposes a future where applied AI can catalyze ethical and equitable advancements in visual analytics.

2nd Talk | Community-Centered Computing for Collective Action and Societal Impact 

Held by: Narges Mahyar, University of Massachusetts, Amherst

Abstract:

Today’s world faces several complex problems, such as climate change, transportation, infrastructure, education, and healthcare. Technology, if designed right, can play an essential role in informing people, raising awareness, sharing data, and connecting communities and decision-makers to make data-informed decisions. In this talk, I present examples of my work on building and studying community-centered tools to empower the general public to engage in real-world sociotechnical problems such as urban planning and climate change. These examples demonstrate my multidisciplinary approach in combining HCI, social computing, information visualization, and human-centered AI to design and build innovative tools and visualization technologies to address complex sociotechnical problems. I will also briefly discuss my work on critical data visualization, which seeks to empower individuals and communities to better understand the data shaping their personal and collective lives. Finally, I will outline my vision for expanding my research to advance democracy, equity, well-being, and sustainability by fostering the inclusion and empowerment of the general public.

Bio:

Narges Mahyar is an Associate Professor in the Manning College of Information and Computer Sciences at the University of Massachusetts Amherst. She was a 2024–2025 Radcliffe Fellow at Harvard University. Narges’s research intersects Human-Computer Interaction, Information Visualization, Social Computing, and Design. She designs, develops, and evaluates novel social computing and visualization techniques that help people explore, understand, and make data-informed decisions. Over the past decade, she has focused on the emerging interdisciplinary area of “Digital Civics,” which explores new strategies for scaling and diversifying public engagement in massive decision-making processes related to civic issues such as sustainable urban design and climate change mitigation. She holds a Ph.D. in Computer Science from the University of Victoria, an M.S. in Information Technology from the University of Malaya, and a B.S. in Electrical Engineering from Tehran Azad University. She was a postdoctoral fellow in the Department of Computer Science at the University of British Columbia from 2014 to 2016 and in the Design Lab at the University of California San Diego from 2016 to 2018. Her recognition in the field has been repeatedly confirmed through many accolades for her research, including five Best Paper Awards from CHI 2023, Eurovis 2022, CSCW 2020, the Council of Educators in Landscape Architecture 2017, and VAST 2014, as well as three Best Paper Honorable Mention Awards from TiiS 2022, DIS 2021, and ISS 2016.

Human-Centred Machine Learning: Sensemaking, Provenance, and Human-AI Collaboration

Held by: Kai Xu, University of Nottingham

Abstract:

The performance of machine learning models, particularly large language models and generative AI, has dramatically improved in recent years, often matching or even surpassing human capabilities. Despite these advancements, many tasks requiring specialised knowledge and analytical reasoning remain beyond the reach of full automation. These tasks, which I refer to as sensemaking tasks, benefit significantly from a collaborative approach that combines human expertise with machine intelligence. This approach, known as human-in-the-loop or mixed-initiative, leverages interactive data visualisation to foster symbiotic collaboration between humans and AI. In this talk, I will showcase some of my past and current projects, illustrating how this method can tackle complex problems across various application domains by utilising 'provenance' information.

Bio:

Dr. Kai Xu is an Associate Professor in the School of Computer Science at the University of Nottingham, where he serves as the co-director of its Visualisation Group. The University of Nottingham is a member of the prestigious Russell Group, which comprises leading UK universities such as Cambridge and Oxford. Dr. Xu holds the position of chair of the UK Branch of Eurographics, the largest professional body for computer graphics in Europe. Additionally, he is a co-organiser of the Visualisation Group at the Alan Turing Institute, the UK’s national centre for data science and AI. With over two decades of experience in data science research, particularly in data visualisation, sensemaking, and provenance, Dr. Xu has collaborated on numerous research projects, securing funding exceeding £10 million. These projects involve partnerships with domain experts from diverse sectors, including government and industry, to develop innovative human-AI collaboration tools that address critical challenges.
