Research Summary:

Artificial Intelligence (AI) is transforming our society. However, a key bottleneck towards its widespread use is the lack of efficient hardware. Themis Prodromakis, PhD, has made remarkable contributions in devising new hardware that supports the increasing computational demands of the AI era. His technology is built upon an electronic component known as a “memristor”, or memory-resistor, which has the ability to 'remember' the amount of charge that has passed through it, thereby simultaneously storing multiple units of data in a single component.

Prodromakis has developed some of the first memristor technologies that are promising for real applications. He first used nanoscale materials to fabricate stable, reliable, and low-energy consumption memristors. He then used those memristors to build novel artificial neural networks—computer circuits emulating the structure of the human brain—that support state-of-the-art machine learning and high speed big-data processing. He further introduced a new circuit design paradigm by embedding memristors within conventional computer circuits, significantly boosting their performance while maintaining a low energy consumption. He has also invented memristor bio-sensors that monitor large-scale neural signals in real time and chips that can communicate with brain neurons over the internet. Several technologies and testing tools he developed have been successfully commercialized and utilized by global businesses and standards organizations. Taken together, he has pushed memristor technologies to become a viable solution to the challenges we face today in the information and biomedical industries.

"The invention of the transistor and integrated circuits have over the past 7 decades transformed our world. Sustaining modern societal needs requires a fundamental re-think of electronics and Memristors promise to bring this change about. I am truly honoured that the contributions of my team and collaborators are recognized with this prestigious award."
