I am a Postdoctoral Fellow in the Department of Computer Science and the Faculty of Information at the University of Toronto, where I work with Syed Ishtiaque Ahmed and Shion Guha. My research in Human-Computer Interaction (HCI) examines how sociotechnical systems facilitate sociopolitical discourse among people from the various communities and how those platforms can be designed and governed to foster greater equity and fairness for different and often conflicting norms and values. I investigate how fairness in algorithmic systems' downstream applications, particularly in the governance of online platforms within culturally diverse communities, is conceptualized and negotiated. I take a community-centered research approach that integrates in-depth formative studies (e.g., contextual interviews, trace ethnography) with large-scale quantitative analyses (e.g., algorithmic audits, text mining), alongside iterative system building and evaluation. Some examples of my recent work include algorithmic audits that expose epistemic hierarchies in language models, community-centered studies of content creators, moderators, and other users navigating ethical challenges shaped by religious values and national identities, and co-design efforts that develop tools for inter-community ethical deliberation. Drawing on sociotechnical systems studies, I critically examine the role of technology in reshaping sociopolitical dynamics in culturally diverse communities, reconceptualizing fairness across race, gender, ethnicity, religion, caste, nationality, linguistic practices, and immigration status. More recently, my research has expanded beyond online platforms to explore the fairness of algorithmic systems in higher education, public service, and gig work. My research has appeared at premier venues including ACM CHI, CSCW, and ICTD and been recognized with Best Paper Honorable Mentions and covered by prominent media outlets. I also received several awards of excellence for outstanding research, teaching, and contributions to diversity and inclusion, and research grants from the University of Colorado Boulder.
Prior to UofT, I completed my PhD and MS in Information Science from the University of Colorado Boulder, where I worked with Bryan Semaan. Previously, I received a MS in Computer Science from Missouri State University and a BSEngg in Computer Science and Engineering from Bangladesh University of Engineering and Technology and worked as a lecturer in the Department of Computer Science and Engineering at Dhaka International University, Bangladesh. As a first-generation scholar and person of color from the Global South, I care about promoting academic and professional development of aspiring scholars, specifically those from marginalized communities. Feel free to reach out to me with questions about grad school and HCI research.
Apart from academic activities, I have always been passionate about painting and sketching. I also like traveling and roaming around new places. In my free time, I also enjoy cooking, rewatch my favorite sitcoms, read fictions, and recite poems.

Plain and old pencil sketch is my go-to medium, but I do paint with acrylic and water color depending on the subject. Human figures with abstractions connecting those with social and cultural sentiments is what I often consider as the topic of my drawings. A series of five paintings I worked on during grad school was "Durga" depicting different ways divine feminine energy is culturally conceptualized in Bengal.
I love traveling to new places. Be that relaxing on the beach in the St. Martin's Island on a full moon light or hiking on high-altitude tracks in Colorado, I hum my favorite classical Bengali or American country music. You can check out my Soundcloud profile. With an interested group, I also enjoy telling or listening to stories. Of what kind? The time I was stuck in an airport for three days straight, or the time I sneaked out of house in middle school! Maybe, you can taste some of my recipes as we share those stories.
