Prof. Robert E Simpson holds an Assistant Professor position at the Singapore University of Technology and Design. His group’s  research lies in the design and development of new materials for applications in photonics, electronics and data storage.

Before Joining SUTD Robert spent his postdoc years in Japan and Spain. After completing his PhD he was awarded a fellowship from Japanese Society for Promotion of Science and spent 3.5 years at the CAN-FOR research group, directed by Prof Junji Tominaga, at the Japanese national institute for Advanced Industrial Science and Technology (AIST). In Spain Robert joined the group of Prof Valerio Pruneri as a COFUND Marie Currie Fellow at the Institute of Photonic Sciences (ICFO) in Barcelona.

In 2012 Robert moved to the Singapore University of Technology and Design, where he formed the ACTA research group. The ACTA research group aims to exploit atomistic modelling and experimentation to design new functional chalcogenide materials for applications in photonics, data storage and nanoelectronics.

Robert’s PhD is from the University of Southampton, UK, where he studied under the guidance of Prof Dan Hewak in the Optoelectronic Research Centre (ORC). His PhD thesis was titled “Chalcogenide Materials for Next Generation Data Storage”.

Dr Xilin Zhou is a postdoctoral research fellow at Singapore University of Technology and Design (SUTD) and a member of the Advanced Chalcogenide Technology & Applications (ACTA) Group. His research focuses on chalcongenide‐based nanostructured materials and devices for data storage.

In July 2014, Dr Zhou graduated with a Ph.D. in Microelectronics and Solid State Electronics from the State Key Laboratory of Functional Materials for Informatics of Shanghai Institute of Micro‐system and Information Technology (SIMIT), Chinese Academy of Sicences (CAS) in Shanghai, China. While at SIMIT, he had the honor of being advised by Prof. Zhitang Song and Prof. Liangcai Wu. He developed next generation data storage cells and high performance memory cells based on novel chalcogenide materials that exhibit energy efficient switching.

In June 2016 Dr Zhou’s PhD thesis was won a prestigious prize. It was awarded the best thesis from any institute in Shanghai.

Weiling Dong

Weiling is a PhD candidate at Singapore University of Technology and Design (SUTD) and a member of the Advanced Chalcogenide Technology & Applications (ACTA) Group.

Weiling Graduated from Suzhou Institute of Nano-tech and Nano-Bionics(SINANO), Chinese Academy of Sciences(CAS) as a Master student in July, 2013. During her masters’ studies she mainly focused on research of high performance cathode materials for lithium sulfur batteries, and investigated the formation of SEI on anode thin films using AFM force curves. With a dream of designing materials in a different way, she initially joined the ACTAlab as a research assistant and spent developed  methods to design and fabricate chalcogenide materials and devices.

Weiling is now a graduate student working towards a PhD. Her research topic involve the design and fabrication of optical filters for applications ranging from imaging to pollution sensing.
