About Me

I am a Ph.D. researcher at Delft University of Technology working on Embedded AI and TinyML systems. My research focuses on understanding and optimizing deep learning workloads on resource-constrained microcontrollers from a system-level perspective.

Current research topics: instruction-level profiling of neural networks on MCUs, energy and latency modeling, split inference, and end-to-end optimization of embedded AI systems.
