I am a Postdoctoral Associate in the Bowers College of Computing and Information Science at Cornell University, where I work with Dr. Aditya Vashistha as part of the Cornell Global AI Initiative. My research examines how AI systems and online platforms shape decision-making, public discourse, identity, and access to information across varied institutional and cultural contexts. I study how bias and accountability gaps emerge not only from models and datasets but also from the institutions, infrastructures, and practices through which these technologies are developed, deployed, evaluated, used, and governed. These include institutional documentation, impact assessments, procurement arrangements, technical benchmarks, low-resource technological ecosystems, and community practices across global contexts. I am particularly interested in cases where assumptions embedded in technologies, evaluation methods, and governance mechanisms do not adequately reflect local conditions, knowledge, and experiences.

My research develops through three interconnected threads. The first, governing, examines policies and institutional mechanisms for making AI and algorithmic decision-making accountable and contestable, including public AI registers, impact assessments, procurement practices, and government uses of algorithms in immigration, social services, and education. The second, evaluating, develops context-sensitive approaches to measuring fairness and bias in language technologies and generative AI, including computational audits, benchmark and language-resource development, and evaluations focused on historically marginalized identities and low-resource languages. The third, situating, investigates the cultural, social, and political dimensions of AI systems and online platforms, including identity work, content moderation, political mobilization, diaspora and immigrant-led organizations, and the experiences of native and Indigenous communities. Together, these threads explain how emerging technologies are institutionally governed, technically evaluated, and experienced and contested within particular social settings.

Drawing on my interdisciplinary training in computer science, information science, and human-computer interaction, I bridge computational experimentation and system building with qualitative, critical, and participatory inquiry. Across these projects, I develop theory, evidence, and tools that are useful to researchers as well as the institutions and communities affected by emerging technologies. My work regularly appears in top computing venues, such as CHI, CSCW, FAccT, GROUP, and ICTD, among others, and has received several Best Paper Honorable Mention Awards. It has also been featured in prominent press and media outlets, such as The Atlantic, Prothom Alo, ACM Crossroads, and Princeton University Press. My research has been supported by funding from the Institute for Pandemics and the National Science Foundation.

Previously, I worked as a postdoctoral fellow in the Department of Computer Science (also affiliated with the iSchool) with Dr. Syed Ishtiaque Ahmed and Dr. Shion Guha at the University of Toronto. I also have experience with independent industry consulting and over eight years of teaching experience (three and half years as instructor of record) across universities in the US, Canada, and Bangladesh. I completed my PhD and MS in Information Science from the University of Colorado Boulder, where I worked with Dr. Bryan Semaan. Previously, I obtained an MS in Computer Science from Missouri State University and a BSEngg in Computer Science and Engineering from Bangladesh University of Engineering & Technology.
