Research: I research networked systems (e.g., Internet, social media platforms, cloud data centers) and their societal impacts, focusing on technologies for developing regions, misinformation countermeasures, data privacy, and efficient cloud infrastructure design. I employ a mixed-methods approach in my research, utilizing generative AI, causal inference, privacy-preserving machine learning, and qualitative methods to address these challenges. Through an interdisciplinary lens, I aim to shape a digital future that is not only more efficient and secure, but also equitable and inclusive across global contexts. I lead the Internet, Data, and Society Lab (IDSL) at LUMS.
