Biography

Alexantrou Serb graduated from Imperial college in 2009 as a biomedical engineer and later obtained his PhD from Imperial college in 2013 in electronics engineering. Since then he has been a research fellow in Prof. Prodromakis' group, working on memristors technology characterisation and application development. His research interests include circuit design, computational neuroscience and biology-machine interfaces. He was appointed Reader at Univ of Edinburgh in May 2022.

Research

One of the greatest challenges of current research is how to embody the level of intelligence found in the brain into a physical computer that operates with the energy efficiency of the brain. To that end, algorithmics, computer architecture design, nanotechnology and ultimately also bio-interfacing must work together, as no isolated approach can deliver this vision. Throughout project FORTE this researcher will be involved in: 1) developing new applications enabled by enmeshing memristors into existing electronics technologies and 2) understanding how the availability of memristive technologies can unlock new capabilities in artificial intelligence systems.

The applications developed in this programme will span from simple, modular micro-circuits employing several memristors to larger scale systems utilising thousands of devices. Examples of the former would include reconfigurable logic (digital) and filter (analogue) blocks that can be aggregated into much larger computational systems much like Lego pieces can be used to construct complicated superstructures. Examples of the latter would include functional blocks that can carry out probabilistic inference, biosignal processing or neutral network-type inference.

The algorithmics part of the research is oriented towards the 'problem of multiplication': multiplication is expensive to perform accurately in hardware. Memristive technologies, however, offer an opportunity to implement not only multiplication, but other basic mathematical operations such as scalar matching in hardware at very low energy. Furthermore, reducing energy budgets for such operations opens the way towards more powerful, more intelligent AI.

Dr Shiwei Wang is a Reader in the Centre for Electronics Frontiers (CEF), School of Engineering at the University of Edinburgh. He received his Bachelor degree in Electronic Engineering (Outstanding Honor) from Zhejiang University, China in 2010 and PhD degree in Microelectronics from University of Edinburgh, UK in 2014. Following his PhD research, he was with SIAT, Chinese Academy of Sciences, China as a Research Assistant Professor before moving to IMEC, Belgium where he worked as a Senior Researcher till December 2020.

Biography

Jiaqi received her Bachelor of Science in Microelectronic Science and Engineering from Shenzhen University, China, in 2017. Then she obtained her Master of Science in Microelectronic Systems Design from University of Southampton, in 2018. She pursued her PhD in Electronic Materials & Devices Research Group, University of Southampton.

Research Interests

She is working towards the memristor-based analogue & mixed-signal integrated circuit (IC) design. In neural recording system, we intend to design a front-end system outputting directly a digital, back-end processed waveform corresponding to neural spikes and demonstrate extremely low power dissipation in the process. The front-end contains an integrating amplifier and a dynamic latch comparator (DLC). Instead of purely amplifying the minute signal, we opt for integrating the micron-volt level signal. The integration process not only filters out noise, but also provides amplification. With memristors implanted along the differential current path, the offset can be tuneable precisely, making the systems operate with power efficiency and high precision.
