Hello — I'm Martí Gimferrer.

Postdoctoral researcher at the Institute of Physical Chemistry, University of Göttingen. I develop and apply quantum-chemical methods for chemical bonding analysis and related phenomena, with contributions to major software packages including Q-Chem and APOST-3D.

About

My main line of research is anchored on the concept of chemical bonding. My doctoral work at the University of Girona dealt with classical but still highly debated questions surrounding the analysis of electronic wave functions, resulting in significant contributions to the Q-Chem quantum chemistry package and the open-source APOST-3D code. Since completing my PhD, I have further branched into the analysis of vibronic wavefunctions and the encoding of chemical information for use in machine learning methodologies, as well as in the modelling of X-ray diffraction data (recent additions to the Olex2 program).

I am currently a postdoctoral researcher in the Computational Chemistry and Biochemistry Group at the University of Göttingen, where I am involved in large research networks funded by the German Research Society. In 2025 I was awarded a grant as principal investigator under the Volkswagen Foundation's NEXT – Quantum Biology call, funding research on the use of chemical bonding algorithms for improving the refinement of protein crystal structures.

Over 8+ years of experience, my work is documented in 30 publications (17 as first/corresponding author, h-index 18) and in software actively used by the chemical community. See my CV for the full record.

Research

My research spans both PhD and postdoctoral work and is defined by its multidisciplinary character. The common thread is a simple but powerful idea: first understand the chemical phenomenon, then find — or build — the computational tool that provides the necessary insight. This philosophy has led me to bridge theoretical and experimental chemistry rather than stay within a single discipline. The three research directions below all grow from the most fundamental and elusive concept in chemistry: chemical bonding.

Chemical bonding analysis: overlapping atomic density contours

Chemical Bonding Analysis

A central theme of my research is the development of quantum-chemical tools to extract chemical bonding information from electronic wave functions. This includes rigorous strategies to assign oxidation states, the design of fragment orbital localisation schemes, and energy decomposition approaches for atomic and inter-atomic contributions. These tools are collected in the open-source APOST-3D code and integrated into Q-Chem.

Nuclear Quantum Effects

When dealing with light nuclei such as hydrogen, the Born–Oppenheimer approximation breaks down and nuclear quantum effects (NQEs) become critical. I develop and apply multicomponent methods — in particular Nuclear-Electronic Orbital (NEO) theory — which treat electrons and selected nuclei on the same quantum-mechanical footing, enabling accurate prediction of anharmonic vibrational frequencies and hydrogen-bond shifts at a cost accessible to large molecular systems. Crucially, a single NEO calculation provides both electronic and nuclear densities, directly capturing NQEs on the density and enabling coupling with chemical bonding codes for deeper mechanistic insight.

Machine Learning & Structural Refinement

Robust chemical bonding descriptors are essential for machine learning models that achieve the right answer for the right reason. I connect descriptors developed over the years with ML to improve our understanding of reactivity, catalysis, and reactions involving metal hydrides. In parallel, in collaboration with the MPI for Multidisciplinary Sciences, I develop quantum-chemical scattering factors that encode bonding, polarisation, and partial charges for X-ray diffraction refinement, while keeping the number of parameters manageable.
