Tawfique Hasan教授个人简介：

Tawfique Hasan is a Professor of NanoEngineering at the Cambridge Graphene Centre, Cambridge University Engineering Department and leads the group. He is also the Deputy Head of Electrical Engineering. Prof Hasan gained his PhD in Electrical Engineering from the University of Cambridge in 2009. He also has an MEng. in Analog Microelectronics from University of New South Wales, Australia. Hasan got his BSc in Electrical and Electronic Engineering from the Islamic University of Technology, Bangladesh in 2001. Prof Hasan has held several research positions in the University since his PhD, including a Junior Research Fellowship in King's College, Cambridge, a National Science Foundation China Foreign Young Scientist Research Fellowship and a Royal Academy of Engineering Research Fellowship to work on graphene based flexible and printable devices. The latter contributed to the foundation of Cambridge Graphene Limited, which was acquired by Versarian Plc in 2017.

He is an Editorial Board Member of Advanced Photonics Nexus and a Fellow of Optica. Prof Hasan is also a Title C Fellow and a Director of Studies in Engineering in Churchill College, Cambridge.

报告简介：

Despite the versatility and functionality, many nanostructured sensors and optoelectronic devices offer only limited performance benefits compared to their traditional offerings. An increasingly popular strategy to address this is to use computational algorithms to enhance or even bring new functionalities to these device outputs. I will give two contrasting examples of this approach to show the enabling nature of this philosophy. In the first example, I will discuss how ink formulation, materials functionality and nano-structuring help the use of simple classification and temperature control algorithms for 2D material-based gas sensors. In the second example, I will introduce ultra-miniaturised optical spectrometers, which functionally works as a set of photodetectors but provides a computationally constructed output.
