Meet Adrian
We connect physical phenomena, sensing, circuits, conversion, hardware architecture, and intelligent computation—then make the whole system observable and adaptive.
From photon to bit to decision.
About
MOSAIC stands for Microelectronics, Optoelectronics, Sensing, and Adaptive Intelligent Circuits. The first three terms identify the group’s technological domains; the final three describe the unifying direction from physical interfaces toward intelligent hardware behaviour.
Microelectronics anchors work in silicon, mixed-signal circuits, data conversion, FPGA and ASIC realization. Optoelectronics includes photonic devices, optical interconnect, microrings, and light–matter interfaces. Sensing includes electronic, optical, event-based, radiation-aware, and multimodal front ends.
Adaptive Intelligent Circuits extends beyond conventional AI. It includes hardware that measures its own behaviour, corrects nonidealities, learns from changing conditions, reallocates resources, or performs inference close to the physical interface.
The ordinary meaning of mosaic also describes the group: distinct technologies, disciplines, methods, and researchers retain their identities while contributing to a coherent physical-to-intelligent hardware stack. Across these areas, the recurring method is to model the physical structure, measure departures from the model, correct them in hardware, observe whether the correction remains valid, and adapt when conditions change.
The nine-tile logo represents sensing, propagation, circuits, observation, silicon realization, photonics, architectures, intelligence, and conversion. Its spectrum of colours refers to optics and Newton’s ROYGBIV spectrum, inclusion and belonging, and the rainbow as a symbol of promise and continuity.
