My research focuses on understanding the evolution of the electrode-electrolyte interface in lithium and sodium-ion batteries. For that, I rely on in situ liquid and gas-phase TEM, as well as identical location studies to observe chemical and structural changes on battery interfaces in real-time, at the atomic scale. In addition, I employ multi-variate statistical analysis of large data sets to study the conductivity of electrolytes for solid-state batteries.

Outside of work, I enjoy spending time and traveling with my wife and two kids. I try to find time to practice sports, such as tennis and squash. One of my favourite hobbies is beekeeping. I love working with bees and enjoy observing their colony dynamics.

A bit about my past. I was born and raised in Portugal and did my B.Sc. and M.Sc. (2013) at the University of Porto, Portugal. After that, I spent 8 years in the United States, where I did my Ph.D. at Virginia Tech (2018) and my Postdoc at the University of Pennsylvania (2021). In those research periods, I combined meso and microfluidic chemical reactors, in situ liquid and gas Transmission Electron Microscopy (TEM), and multivariate rate analysis to study batteries, (electro)catalysis, catalyst corrosion, particle nucleation and growth, etc. Between 2021 and 2024 I decided to develop my experience at industrial R&D. First, I led the electrocatalysis group Net4CO2 Incubation Laboratory, Porto. Then I joined Simoldes Energy, Portugal, to lead the technical development of sodium-ion batteries.
