I am an Assistant Professor in the Department of Electrical and Computer Engineering at Cornell Tech. My research interests lie at the intersection of computer architecture, systems, machine learning and environmental sustainability. The central theme to my research is co-designing solutions across the computing stack (applications, algorithms, systems and architecture, circuits and devices) to design and implement computer systems and hardware in new ways to improve the performance, efficiency, and environmental sustainability of emerging applications. I lead the S4AI group, working on Specialized, Scalable, and Sustainable Systems for AI.

Through research, I am driven to realizing practical impact, building interdisciplinary research communities, and pathfinding. I led the characterization of industry scale neural personalized recommendation models, outlining paths for future AI hardware design and academic research into specialized systems for AI. Based on the key insights we built open-source systems' benchmarks and tools that have been standardized as part of the community efforts such as MLPerf. I also built the first architectural model of computing's embodied carbon (ACT), which industry now uses to account for the manufacturing footprint of data center hardware.

My current work argues that AI's rapidly growing energy and environmental footprint, often framed as a modeling problem or a grid problem, is at its core a systems problem — and that the largest levers lie in how we characterize, serve, and provision AI infrastructure. Characterization comes first: emerging agentic AI workloads compose many models and tools into multi-step pipelines, so the cost of a task is set by how that pipeline is assembled and served rather than by model size alone, and careful measurement becomes a prerequisite for efficient design. Building on what characterization exposes, we co-design algorithms, systems, and hardware to remove the resulting overhead, and we are rethinking the contract between AI services and the power grid so that data centers can become flexible participants in the grid rather than inflexible loads. Finally, stepping back from operational energy to the full hardware life cycle, where manufacturing increasingly dominates computing's carbon footprint, my research treats environmental impact as a first-order design principle across the computing stack. This work is conducted with industry and government partners including Meta, Microsoft, NVIDIA, and the U.S. Department of Energy.

Honors/Awards: My work has been featured in venues such as Bloomberg Green, The Guardian, and CNBC. I have advised the German Federal Ministry for the Environment (BMUKN) on sustainable AI policy. My research has received an Amazon Research Award (2026), Google's ML and Systems Junior Faculty Award (2025), and Google's Academic Research Award (2024). My work has been awarded an IEEE MICRO Top Picks (2022 and 2023) and IEEE MICRO Top Picks Honorable Mention (2021), as well as received Best Paper Nominations at the Parallel Architectures and Compilation Techniques (PACT 2019) and Design Automation Conference (DAC 2018). My dissertation received the SIGARCH Outstanding Ph.D. Dissertation Honorable Mention in 2023 as well as the MICRO Outstanding Ph.D. Dissertation Honorable Mention in 2023. I received my Ph.D. in Computer Science at Harvard University and BSc in Electrical and Computer Engineering from Cornell University.

Prospective students: I am actively looking for motivated, ambitious, and passionate graduate students, postdoctoral scholars, and undergraduate. If you are interested in working with me please read the following page.
