Luke Theogarajan

Luke Theogarajan is a Professor of Electrical and Computer Engineering at the University of California, Santa Barbara (UCSB). His research focuses on integrating nanoscale sensors with conventional CMOS circuits, developing smart biosensors, and advancing neurotechnology through novel neural activity reporters and CMOS image sensors. He leads the Biomimetic Circuits & Nanosystems Group, exploring interdisciplinary applications in quantum computing, probabilistic hardware, and silicon photonics.

Key research areas include:

• Probabilistic computing architectures and p-bit devices
• Quantum advantage in combinatorial optimization
• Photonic interconnects and silicon photonics for data centers
• Nanofabrication techniques for biosensors and neural interfaces
• MEMS-based retinal prostheses and neural recording systems

His recent publications emphasize CMOS-compatible Ising/Potts annealing systems, high-density silicon photonic interconnects, and microneedle-based glucose sensors. Over 20 years of work includes foundational contributions to CMOS biosensors, optoelectronic oscillators, and wafer-scale integration of memristive memory.
