Biography

Dr. Wang Bo, Angela is an Assistant Professor at SUTD since September 2020. Her research interests span various aspects of energy-efficient computing systems, architecture and circuit design, including on-device artificial intelligence, neuromorphic computing, biomedical wearables and ultra-low voltage memories. Particularly, her research work on biomedical wearables was featured by The Straits Times in 2020. She authored and co-authored many papers in prestigious journals and conferences, including JSSC, TCAS-I, TVLSI, A-SSCC, MobiSys, DATE, etc. She has served as a reviewer for journals and conferences such as TCAS-I, TVLSI, TCAS-II and ISCAS. Since 2021, she has also served as an editorial board member of JCSC. She is a Track Session co-chair of EuCNC 2021. She was the recipient of IEEE Circuits & Systems Seoul Chapter Award in 2014.

Dr. Wang received her Ph.D. degree from Nanyang Technological University in 2015. Prior to joining SUTD, she was a research fellow, working with Prof. Peh Li-Shiuan (IEEE Fellow) at the National University of Singapore from 2016 to 2020. Before that, she was a staff engineer at MediaTek Singapore. She is an IEEE senior member.

About Neuromorphic Computing

Neuromorphic Computing deploys Spiking Neuron Network (SNN) models and learning rules to solve machine learning problems in a more energy-efficient way compared to conventional Artificial Neural Networks (ANN). SNN deploys all-or-nothing discrete spikes for layer-by-layer neuron communication. Similar to ANN, SNN is capable of inferencing a pre-defined problem with an analogy to biological neurons. A few ASICs, e.g. TrueNorth, Loihi, Zeroth from industry have emerged and been showcased their superiority in power and energy efficiency as next-generation AI hardware.

Our research group is working with Prof. Peh Li-Shiuan at NUS and other professors at SUTD to design and deliver (1) energy-efficient on-chip inference and training architectures and (2) ultra-low power edge AI systems, e.g. mobile robots, medical wearables by leveraging SNN. For any Ph.D. applicant with interest in such a research domain, please feel free to contact Prof. Wang via bo_wang@sutd.edu.sg for more information. Familiarity with machine learning algorithms/frameworks, RTL design with Verilog/VHDL, and/or hardware-software co-design methodology will be a strong plus.
