Currently, he is working as a postdoc on the topic “Surface segregation and stability of catalysts for electrochemical conversion of CO2” under Dr. Ruud Kortlever and Dr. A.J. Bottger (Material Science & Engineering, TU Delft). His research interest are in material science with a particular interest in local corrosion and electrocatalyst materials and understanding their reaction mechanisms and underlying concepts.

PhD Students

Andrea was born in Costa Rica and studied Chemical Engineering at the University of Costa Rica. After working for a couple of years, she moved to the Netherlands in 2014 to study Sustainable Energy Technology at TU Delft.

Her master thesis was focused on the development of a semiconductor photoelectrode for direct solar to hydrogen conversion. In March of 2017 she started a PhD in the Process and Energy department on the upscaling of an integrated battery and electrolyser system (the Battolyser).

After having graduated from the master program Chemical Engineering in Delft and completing his master thesis on indirect CO2 methanation in the Large-Scale Energy Storage group under Prof. dr. ir. Wiebren de Jong, Daniël started working in the electrochemical conversion group in September 2019. His main research focus is on bimetallic CO2 reduction electrodes, (high-throughput) electrode screening and electrode design under industrial conditions.

Simone Asperti

Simone studied Chemistry (BSc) and Chemical Sciences (MSc) at the Università degli Studi di Milano, spending both his BSc and MSc training period at the ELAN group, coordinated and supervised by Prof. Luigi Falciola, working on the investigation and assessment of the behaviour of the titanium dioxide nanotubes for electroanalytical purposes.


Currently, his PhD project, supervised by Dr. Ruud Kortlever and Dr. Yaiza Gonzalez Garcia (Material Science & Engineering, TU Delft), is related to the investigation of the local electrode conditions and environment during electro-reduction processes, in particular the electrochemical conversion of CO2 to hydrocarbons, with the aim of enhancing the selectivity and productivity of the CO2ER and the lifetime of the electrodes.

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.

Asvin hails from Kochi, a city in the south of India. He obtained his Bachelor of Technology (B.Tech) degree in Chemical Engineering from National Institute of Technology, Raipur, India, in 2017.  He then obtained his Master’s degree (M.Sc) in Sustainable Energy Technology, from TU Delft, in 2019, with a thesis on “Modelling of Multi-Tubular Fixed-Bed Reactor for Fischer-Tropsch Synthesis to Produce Synthetic Crude Using Syngas Obtained from the Work’s Arising Gases of an Integrated Steel Mill” with Prof. dr. Wiebren de Jong, in collaboration with Tata Steel Nederland B.V. He then joined the Kortlever group at TU Delft, in 2020, as a PhD student and focuses on the “Integration of Electrochemical CO2 Reduction Reactor into a Process System” co-supervised by Prof. dr. Wiebren de Jong. His research mainly addresses solvent selection for efficient electrochemical CO2 reduction, impact of feedstock and electrolyte contaminants on reactor performance, and process system modelling of large-scale reactor for industrial implementation.

Aleksandra joined the group as a PhD student in 2020 to work on the “C is for Catalyst” project. She obtained her bachelor diploma from Warsaw University of Technology (Poland) and continued with a master studies at the University of Stuttgart (Germany). She gained experience in working with carbon materials during her stay in Girona (Spain), where she investigated electrochemical application of reduced graphene oxide for removal of persistent water contaminants.


Aleksandra’s current research is focused on investigating different carbon (support) materials for electrocatalytic reactions. The results of her project will provide an insight into relationship between functionalization of carbon-based materials, by hetero-doping or doping with small amount of metals, and resulting electrocatalytic performance. The final stage will involve testing the synthesized electrodes in the industrially relevant conditions.
