He is originally from Beijing, China.

Nicola Molinari

Nicola earned a BS and a MS in Physics from the University of Padova (where people of the caliber of Galileo once taught!) in 2013, and spent a year in the UK as part of the ERASMUS scholarship program. He then was awarded a scholarship in the EPSRC Centre for Doctoral Training on Theory and Simulation of Materials at Imperial College London, where he earned a MSc and a PhD in Physics. Nicola joined the MIR lab at its very origin as a Postdoctoral Fellow. Currently he is a research engineer at Bosch, USA and a visiting associate at MIR lab. His research interests are at the interface between computational condensed matter physics and materials science, and include ionic transport and energy storage, membrane permeation, and mechanical properties of polymers. Among others, he has received the Materials Design Research Prize, the Johnson-Matthey Prize for the Best PhD, and the Blackett Laboratory Industry Club Thesis Prize. Outside the academic walls, his interests include, but are not limited to, cooking, chess, triathlon, and hiking.

Zachary Goodwin

Zac earned his MSci in Chemistry with Molecular Physics from Imperial College London (ICL) in 2017. He continued on at ICL in the Theory and Simulation of Materials Centre for Doctoral Training, where he obtained an MSc in Physics (2018) and his PhD in Materials Science (2022). His research interests include theory and simulation of concentrated electrolytes, in the bulk and at electrified interfaces, with a particular focus on the role of ionic aggregation and solvation; strong electron interactions and broken symmetry phases in 2D moiré materials, which was the focus of his PhD and first postdoctoral position in the National Graphene Institute at the University of Manchester; and DFT calculations of charged molecules/defects interacting with graphene multilayers. Zac joined the MIR group in 2022 as a Postdoctoral Fellow to perform large scale atomistic simulations, using the methods developed within the group to obtain accurate and data efficient machine learned interatomic potentials, on various systems in the area of energy materials, such as polymer electrolytes for batteries and barocaloric materials. In his spare time, he enjoys cycling, bouldering, hiking, skiing, and making pasta.
