Speaker: Anna Lauren Hoffmann

Assistant Professor

The Information School

University of Washington


As we recognize the ways data-driven technologies and processes can inflict harm, we look towards ethics to help foster better futures. In this “Conversation with PERVADE” we’ll talk with Dr. Hoffman about the normative ideals that shape how we think about harms driven by information technologies—and their solutions.

She is a senior fellow with the Center for Applied Transgender Studies and a founding member of AfterLab, a research group dedicated to the critical and cultural study of information, data, and archives in crisis and transition. Her work has appeared in New Media & Society, The Review of Communication, Library Quarterly, and Convergence: The International Journal of Research Into New Media Technologies.

Speaker: Amandalynne Paullada

Postdoctoral Fellow

Biomedical Informatics and Medical Education

University of Washington School of Medicine


This talk will focus on the importance of datasets and benchmarks to responsible machine learning (ML), the current state of dataset curation and reuse in ML, best practices for data use by ML researchers and developers, and understanding the social impact of digital data practices.

Amandalynne Paullada

Amandalynne Paullada is a NLM postdoctoral fellow in the department of Biomedical Informatics and Medical Education at the University of Washington School of Medicine. Her doctoral work, completed in the Department of Linguistics at the University of Washington, focused on the societal impacts of natural language processing technologies.

Speaker: Alex Hanna

Director of Research

Distributed AI Research Institute (DAIR)


The increasing focus on big data, AI, and data-driven modeling to make decisions has raised a number of ethical concerns about the data itself and the people it affects. In this conversation, Dr. Alex Hanna will discuss work she is doing as Director of Research for the Distributed AI Research (DAIR) Institute and her thoughts on how to bring more social science and critical data science theories and methods into the computational work driving technological change.

Alex Hanna

Dr. Alex Hanna is Director of Research at the Distributed AI Research Institute (DAIR). A sociologist by training, her work centers on the data used in new computational technologies, and the ways in which these data exacerbate racial, gender, and class inequality. She also works in the area of social movements, focusing on the dynamics of anti-racist campus protest in the US and Canada.

Dr. Hanna has published widely in top-tier venues across the social sciences, including the journals Mobilization, American Behavioral Scientist, and Big Data & Society, and top-tier computer science conferences such as CSCW, FAccT, and NeurIPS. Dr. Hanna serves as a co-chair of Sociologists for Trans Justice, as a Senior Fellow at the Center for Applied Transgender Studies, and sits on the advisory board for the Human Rights Data Analysis Group and the Scholars Council for the UCLA Center for Critical Internet Inquiry. FastCompany included Dr. Hanna as part of their 2021 Queer 50, and she has been featured in the Cal Academy of Sciences New Science exhibit, which highlights queer and trans scientists of color. She holds a BS in Computer Science and Mathematics and a BA in Sociology from Purdue University, and an MS and a PhD in Sociology from the University of Wisconsin-Madison.

Speaker: Mark Dredze

John C. Malone Associate Professor

Department of Computer Science

Johns Hopkins University


Join us for the next “In Conversation With PERVADE” where we will meet Dr. Mark Dredze (Johns Hopkins University) and learn about his experiences navigating the ethical dimensions of public health informatics and using social media data and machine learning techniques to improve public health outcomes.

Mark Dredze

Mark Dredze is the John C Malone Associate Professor of Computer Science at Johns Hopkins University. He is affiliated with the Malone Center for Engineering in Healthcare, the Center for Language and Speech Processing, among others.

He obtained his PhD from the University of Pennsylvania in 2009.

Prof. Dredze’s research develops statistical models of language with applications to social media analysis, public health and clinical informatics. Within Natural Language Processing he focuses on statistical methods for information extraction but has considered a wide range of NLP tasks, including syntax, semantics, sentiment and spoke language processing. His work in public health includes tobacco control, vaccination, infectious disease surveillance, mental health, drug use, and gun violence prevention. He also develops new methods for clinical NLP on medical records.

Speaker: Libby Hemphill

Associate Professor
