Knowledge for a sustainable world

BEng, MSc, PhD

Dr. Yixing Sui joined the University of Greenwich in October 2019 as a Research Fellow after completing his PhD in Bioscience Engineering at the University of Antwerp (Belgium) where he studied the production of nutritional protein with Dunaliella microalgae.

Dr. Yixing Sui obtained his MSc in Environmental Sciences from Wageningen University in 2013 (the Netherlands) and BEng in Environmental Engineering from Tianjin Chengjian University in 2011 (China), with research activities covering aerobic and anaerobic wastewater treatment and resource recovery from black water (source separated toilet wastewater) using microalgae.

From 2013-2014, Dr. Yixing Sui has worked as a Research Assistance at the Netherland Institute of Ecology (NIOO-KNAW). During this time, he operated a pilot-scale upflow anaerobic sludge blanket (UASB) reactor and a microalgal photobioreactor for biological energy and nutrients recovery from black water.

Dr. Yixing Sui is interested in:

  • Microbial biotechnology for natural bio-compounds production, and their industrial utilisation/application (e.g. food and pharmaceutical)
  • Resource recovery from waste and waste products to contribute to environmental sustainability and a circular economy
