Purusothmn Nair PhD

Postdoctoral Research Assistant


Dr Purusothmn Nair will be the lead researcher for WP4 on Sprint 2 of the Oxford Agile Initiative working on mathematical optimisation for nutrient recovery. He joined the University of Oxford as a postdoctoral research assistant after completing his PhD in Chemical Engineering (Process Integration) at the University of Nottingham Malaysia. His PhD research focused on the development of process integration techniques for determining the optimal deployment of negative emissions technologies for sustainable energy planning.

Throughout his research, he made use of various tools such as Python, LINGO and Microsoft Excel to perform process optimisation. During his PhD, he was also the lead developer of the COP26 Trilateral Research Initiative Grant hosted by the British Council. This grant was purposed to establish and develop trilateral collaborative partnerships between institutions in the United Kingdom, Japan and one or more ASEAN countries. He was responsible for formulating an energy planning model tailored to the ASEAN region. Before pursuing a PhD, he graduated with First Class Honours in Chemical Engineering from the University of Manchester in 2018.
