Brojogopal Sapui

Researcher working at the intersection of AI security, hardware security, edge intelligence, and trustworthy physical AI.

Biography

Short professional biography

I completed my PhD at Karlsruhe Institute of Technology with research focused on the physical security of emerging AI hardware accelerators. My work has covered side-channel analysis, fault injection, reliability, and trustworthy design for non-traditional AI hardware platforms including Hyperdimensional Computing, Spiking Neural Networks, and flexible neuromorphic circuits. I am currently working at NaMLab in Dresden, where my broader interest is cross-layer security that connects devices, circuits, architectures, accelerators, and deployed AI systems.

Position this page as: a concise introduction for collaborators, recruiters, students, and researchers who want to understand both your background and your technical direction.

Current focus

Current technical direction

This website is organized around a broad but connected set of themes: software-side security of AI models, hardware-side security of deployed accelerators, cloud and edge deployment trust, and the security implications of newer paradigms such as generative AI, agentic AI, and physical AI. A central motivation is to explain how the threat model changes as AI systems move from isolated inference engines to interactive systems and then to embodied systems acting in the physical world.

Why this website

A research portal, not only a profile page

The goal is to make this site useful both as a professional identity page and as a readable technical resource. Each topic page can function like a mini survey, while the research-watch pages can capture timely notes, open questions, and commentary on newly emerging directions.
