Keynote Speakers

Raychelle Burks

American University

After working in a crime lab, Dr. Burks returned to academia, teaching, and forensic science research. Her research team is focused on the development of colorimetric and luminescent sensing systems with integrated image and chemometric analysis for forensic applications. She is co-creator of the Digital Imaging and Vision Applications in Science (DIVAS) project which created a pedagogical and programmatic "onramp" that empowers natural science majors to engage in authentic computational problems as members of community of practice.

Beyond the bench, Dr. Burks is a popular science communicator appearing regularly on TV, radio, podcasts, and print outlets. Most recently, she was a series regular in the Smithsonian Channel show "The Curious Life and Death Of..." and writes a science-meets-true crime column called “Trace Analysis” for Chemistry World. In 2020, she was awarded the American Chemical Society's Grady - Stack Award for Interpreting Chemistry for the Public.

Central to Dr. Burks' research, teaching, and service is the central tenet that equitable, diverse, and inclusive spaces and practices both respect people and produce scientific outcomes of greater integrity. She is a member of several local, national, and international committees, task forces, and projects focused on social justice and STEM.

Theresa Tanenbaum

UC Irvine

Dr. Theresa Jean Tanenbaum (“Tess”) is a game designer, artist, activist, and professor in the Department of Informatics at UC Irvine where she is a founding member of the Transformative Play Lab ( Dr. Tanenbaum’s work is playful, provocative, and interdisciplinary, frequently straddling the line between art, design, and research. She is an expert in the design and study of digital storytelling systems that produce experiences of role-taking and identity shift by drawing on techniques from theater and the performing arts. Her work seeks to create possibilities for social and individual change by highlighting how the identities that we inhabit in the world are contingent and negotiated. These experiences of transformative theatrical play create possibility models that are emancipatory, allowing oppressed and marginalized people to inhabit new identities that create possibilities where there were none before and reclaim power and agency denied to them. She has been instrumental in helping create new, more inclusive, policies within the academic publishing world that make it possible for people to correct their names on previously published scholarship. She has worked with COPE, the ACM, SAGE, Springer, Taylor & Francis, Elsevier, and many other publishers to develop identity practices in publishing that safeguard the privacy of transgender authors seeking to update their scholarly records to reflect their correct names. She is the founder of the Name Change Policy Working Group ( and serves as the VP for Publications for ACM SIGCHI, and on the board of the Association for Research Into Digital Interactive Narratives (ARDIN) as the director of EDI initiatives.

Manasi Vartak is the founder and CEO of Verta, an MIT-spinoff building software to enable high-velocity machine learning. The Verta platform enables data scientists and ML engineers to robustly version ML models, collaborate and share ML knowledge, and when models are ready for graduation, to deploy and monitor models in production environments. Verta grew out of Manasi's Ph.D. work at MIT on ModelDB, the first open-source model management system deployed at Fortune-500 companies. Manasi previously worked on deep learning for content recommendation as part of the feed-ranking team at Twitter and dynamic ad-targeting at Google.
