During 2016-2019, Shilong studied at Huazhong University of Science and Technology, Wuhan and Université Paris Sciences et Lettres, Paris. He was awarded a double Master degrees of “New Energy Science & Engineering” from China and France. Now, Shilong started his PhD life in October 2019 in the Kortlever group, co-supervised by Prof. dr. Wiebren de Jong. His research mainly focusses on biomass-derived porous carbon materials for CO2 electrochemical reduction. In this study, he attempts to integrate multiple renewable energy sources to achieve high value utilization of biomass and cyclic conversion of carbon dioxide.

In 2019, Boaz obtained his MSc Chemical Engineering degree from the Delft University of Technology. He worked for 7 months in the lab of Dr. Wilson Smith during his MSc thesis and studied ion transport behaviour in monopolar and bipolar membranes with electrochemical impedance spectroscopy with the primary goal to enhance electrolysis. Early 2020, he joined the Kortlever group as a PhD student and works now on electrochemical ammonia synthesis via nitrogen reduction. Mainly, he is interested in developing and using novel types of electro-catalytic materials to overcome the ammonia selectivity challenge.


Nandalal comes from a place called Bangalore in India. He completed his Bachelor of Technology (BTech) in chemical engineering from National Institute of Technology, Trichy, India, back in 2016 after worked for 7 months in an optical fibre manufacturing plant. Then he completed his MSc in Chemical Engineering at TU Delft between 2017-2019 with a thesis on the topic of "Control crystal polymorphism using surface decorated liquid-gel interfaces" with Dr. Burak Eral. He started working as a PhD student in the Kortlever group in 2019 and focuses on the "Optimization of a two catalyst system for CO2 reduction" wherein he predominantly focuses on reactor designs, electrode combinations, flow behaviour etc. In his free time, Nandalal likes to play games, make simple graphic designs and sketch. Also occasionally he tries his hand at badminton with friends. 


Ming received his Master's degree in Materials Science and Engineering from Beihang University, China. His master thesis was focused on using chemical vapor deposition to prepare multilayer graphene and functionalized them through surface modification. In September 2019, he started his PhD program at TU Delft and is supervised by Prof. dr. J.R. van Ommen (PPE Group, Chemical Engineering at TU Delft) and Dr. Ruud Kortlever. In this project, he is interested in the rational design of electrocatalysts for CO2 reduction using atomic layer deposition.
