Subject: 19.12.16 Three postdoc positions in computational chemistry and machine learning for molecular science (DTU, Denmark)
The Sections for Atomic Scale Materials Modelling at DTU Energy and Cognitive Systems at 
DTU Compute, Technical University of Denmark (DTU), are looking for outstanding candidates for 
three 2-year postdoc positions within the fields of computational chemistry and machine learning for 
molecular science. The research positions are part of the Novo Nordisk Foundation Exploratory 
Interdisciplinary Synergy Programme: Self-correcting Unsupervised Reaction Energies (SURE), 
which brings together researchers from DTU Energy and DTU Compute.

Project descriptions
The successful candidates will use electronic structure modelling (e.g. DFT and wave function methods) 
and machine learning algorithms to develop a framework for uncertainty-aware prediction of chemical 
reaction networks. The framework development will consist of the following postdoc projects:

1. DFT and wave function electronic structure methods will be used to calculate high-fidelity data for 
the thermodynamics and kinetics of selected chemical reactions. The developed methodology will be 
used to train the data-driven models developed in the parallel projects, as well as to validate them for 
the prediction of degradation reaction networks of organic electroactive molecules used in redox flow 
batteries. The ideal candidate will have experience in modelling of reaction mechanism of molecular 
systems.

2. Molecular graph operation based methods will be established and used for reaction intermediate 
and product candidate generation. Machine learning predicted energies of these structures will help us 
create probabilistic model of the reaction networks. Furthermore, new tools will be developed to 
provide uncertainty guided analysis on reaction products and mechanisms. Experience in scientific 
programming (e.g. Python) and Bayesian statistics will be advantageous.

3. Graph convolutional neural network models will be built for evaluating errors and uncertainties in 
molecular energies obtained from electronic structure simulations of varying complexity. Model training 
methods that can utilize multi-fidelity data will be incorporated. The developed framework will be 
utilized to predict energies for any given molecular structure along with uncertainties, to build 
probabilistic models for reaction networks. Experience in machine learning model development is 
expected.

The three projects will be carried out in close collaboration between the two sections and linked to 
other ongoing projects in the sections working on clean energy materials and machine learning for 
accelerated materials discovery.

Qualifications
Candidates should hold a PhD or equivalent degree in computer science, physics, chemistry or 
materials science. The candidate must have a strong background in computational chemistry, physics 
or materials science and/or machine learning, and are expected to have performed original scientific 
research within the relevant fields listed above for the specific position(s). Moreover, the successful 
candidate:
- is innovative and able to work both independently and in cross-disciplinary teams
- has good communication skills in English, both written and spoken
- is able to work independently and take responsibility for progress and quality of projects.

Assessment
The assessment of the applicants will be made by: Head of Section, Professor Tejs Vegge, 
Professor Ole Winther, Associate Professor Mikkel N. Schmidt, Assistant Professor Piotr de Silva 
and Researcher Arghya Bhowmik
