He established the Applied Power Electronics Laboratory (The Long Group) and he is currently leading a research team comprised of 3 Postdoctoral Research Associates and 8 PhD students. His research portfolio covers from power electronic devices to power converters to drive and power systems, mainly for transport electrification and renewable energy applications. Since his Lectureship, Dr Long has been awarded more than £2.5 million research grants where half are funded by the UK government and the rest directly from industrial sponsors. Dr Long has built strong connections with industrial partners including the SAIC Motor, Dynex Semiconductor, STMicroelectronics, Siemens, CBMM, CRRC, Wuxi SES, Huawei, NIO, etc. Prior to joining Cambridge, he has worked for General Electric (GE) where he has led or played an important role in many rewarding projects such as the first transformer-less all electric oil-platform supply vessel, the first large scale all electric warship (Type 45 Destroyer), and the first electromagnetic aircraft catapult demonstrator.To date, Dr Long has more than 40 academic papers published at international journals and he is the inventor of 5 international patents. Dr Long received the B.Eng. from the Huazhong University of Science and Technology, China, the first class B.Eng. (Hons.) from the University of Birmingham, UK in 2009, and the Ph.D. from the University of Cambridge, UK in 2013. Dr Long is a Chartered Engineer registered with the UK Engineering Council. Abstract：Wide Band Gap (WBG) devices such as Silicon Carbide (SiC) and Gallium Nitride (GaN) have been widely considered as the next generation of power semiconductors. However, to unlock the full potential of SiC and GaN devices, design of power converters principles need to be revisited and modified. In this talk will give introduction of selected novel technologies in switching modulation, magnetic components, and converter integration which transfer the advantageous physical properties of WBG devices into high efficiency and high power density energy conversion. Emerging applications enabled by WBG devices such as wireless power transfer for EVs and ultra-high power density 48V DC systems for datacentres will also be introduced. Examples and results used for the aforementioned technologies and applications are exclusively from the Applied Power Electronic Laboratory in Cambridge. 

Energy demand and climate change are significant global challenges for the next few decades. To tackle these challenges, China announced an ambitious plan to have CO2 emission peak before 2030 and achieve carbon neutrality before 2060.We are organising an Energy Geotechnics Webinar to promote Energy Geotechnics research and potential collaborations with Chinese academics and industry. This webinar will cover the following topics:• Offshore foundation• Carbon geological storage• Shallow/deep geothermal• Nuclear waste disposal• Methane hydrateThe webinar will occur weekly or biweekly from Sep to Dec 2021. It will be hosted by Dr Budi Zhao from University College Dublin and co-hosted by Prof. Zhongxuan Yang from Zhejiang University. Speaker: Holger Ott

Venue: ZOOMAbstract: Recent reports by the National Academies have encouraged investment in developing a more comprehen-sive understanding of network dynamics at the intersection between human and engineered networks. Concurrent-ly, cities are addressing rapid urbanization challenges by implementing socio-technological changes in their infra-structure systems as they evolve toward becoming smarter cities. The success of such an evolution, however, relies on solutions that can combine data from individual infrastructure components to urban scale networks. A great deal of research has focused on developing an understanding of data analytics at the scale of the city and of individual infrastructure components. However, there is a gap in our understanding, data collection approaches, and analytical methods to integrate and visualize such disparate data and complex network dynamics. This presentation will describe efforts to formalize and implement a Smart City Digital Twin platform, with an emphasis on efforts to under-stand, model, and improve energy consumption and disaster mobility across spatial scales in cities, to foster more sustainable, resilient, and livable cities.Biography: Dr. John E. Taylor is the inaugural Frederick Law Olmsted Professor of Civil and Environmental Engineering at Georgia Tech, where he currently serves as the Associate Chair for Graduate Programs and Research Innovation in the School of Civil and Environmental Engineering. Dr. Taylor received his PhD from Stanford University in 2006. At Geor-gia Tech, he is founder and Director of the Network Dynamics Lab, which focuses on; (1) achieving sustained energy conservation by coupling energy use with occupant networks and examining inter-building network phenomena in cities, and (2) understanding and improving response times by affected human networks during extreme events in urban areas. Dr. Taylor’s research has received over $8M in funding from the National Science Foundation, the Depart-ment of Energy, the Alfred P. Sloan Foundation, and other public and private funding sources. His research was award-ed the National Science Foundation’s CAREER Award in 2011. In 2020, Dr. Taylor was elected into the National Acade-my of Construction for his research and pedagogical efforts to improve urban sustainability and resilience and guide the evolution of smart cities. Dr. Taylor has authored over 250 technical publications, won five journal best paper awards, and founded two technology startups. 

ABSTRACT: Thanks to the digital revolution, we live in a world with an increasing abundance of data about everything in our lives. In terms of the built environment, we are now able to digitally capture data about our buildings and infrastructure assets in a way which was not possible even 20 years ago. But the question remains, how to harness that data to best eect? Our built environment is composed of a complex system of infrastructure systems and buildings which underpin the services which we, their users, value. They are interconnected and inter-reliant. How can we use better data about these systems to help us provide andreceive better services, which help our communities to ourish? How can we use that data to help us address the climate crisis and reinstate the balance between the built and natural environments? In this lecture, Dr Schooling will explore the answers to these questions, and describe how the Cambridge Centre for Smart Infrastructure has been working with colleagues from academia, industry and policy to enable the adoption and implementation of research outcomes into practice.BIO: Dr. Jennifer Schooling OBE is Director of the Centre for Smart Infrastructure and Construction (CSIC) atthe University of Cambridge. Jennifer is passionate about changing the way the infrastructure and constructionindustries view data, to become a vital asset in its own right, and as an engineering tool for tackling thekey challenges facing our industry, including climate change, resource constraint and resilience. She is amember of the UK’s Digital Framework Task Group (DFTG) and the Infrastructure Client Group’s Digital TransformationTask group (DTTG). In 2019 she was awarded the Institution of Civil Engineers President's Medalfor her work.CIRCLE: The Center for Infrastructure Resilience in Cities as Livable Environments is one of three researchthemes supported by the joint Dynamic Research Enterprise for Multidisciplinary Engineering Sciences(DREMES), established between the University of Illinois at Urbana-Champaign (UIUC) and Zhejiang University(ZJU).

Introduction: IASM visitors plan to organize an irregular seminar from June 20 to July 20. We will arrange about eight 1.5-hour introductory talks, on recent topics in hyperbolic geometry (and low-dimensional topology). The purpose of this seminar is to enhance communication and learn advances in the area. Venue: Lecture Hall, Institute for Advanced Study in Mathematics, No.7 teaching building, Yuquan CampusSpeaker: MA Jiming, Associate Professor, Fudan UniversityAbstract:Unlike the spherical and parabolic cases, complete classification regarding hyperbolic Coxeter polytopes of finite volume is far from being obtained. Poincare and Andreev addressed this problems in dimensions 2 and 3, respectively. In dimensions larger than or equal to four, complete classifications of Coxeter polytopes are achieved scatteredly only in the cases of simplexes, n-polytopes of finite volume with n+2 facets and bounded n-polytope with n+3 facets, etc. We obtain the complete classification for compact hyperbolic Coxeter 4-polytopes with 8 facets. This is joint work with Fangting Zheng.More info: http://www.iasm.zju.edu.cn/iasm/2021/0622/c58777a2397709/page.htm
