Research topic: End-to-end learning of outcomes of organic chemistry reactions
Project description: Efficient organic synthesis can only be carried out by highly experienced chemists using knowledge and mechanistic thinking acquired over long years of study. Any improvement in this field would have a considerable benefit in terms of speed and efficiency on drug-discovery projects, as well as cost and hazard effects reduction. The prediction of the outcome (products) of a reaction with a given set of reactants and reagents remains unsolved. Recent work (Schwaller et al, 2018) has led to highly promising results by modeling chemical reactions like language translation, through deep LSTM recurrent neural networks (Hochreiter and Schmidhuber, 1997). ESR we will advance this approach by means of embedding chemical-related data and developing special neural network architectures suitable for modeling languages with small vocabularies but at the same time with rich expressiveness. The major outcomes are expected to be development of the end-to-end-differentiable systems for chemical reaction modelling and training it on the set from Bayer’s in-house database; development chemical-related embeddings, which could be used separately for modelling chemical properties and benchmarking the model on separate test sets and validating the ability of the model to adapt to different classes of organic reactions in collaboration with other ESRs.
Personal introduction: Early-stage researcher of the Advanced machine learning for Innovative Drug Discovery (AIDD) consortium, focusing on novel deep learning architectures and approaches for the prediction of products of organic chemical reactions.
At university, working in a chemical lab, I discovered machine learning and saw its promise for developments in chemical sciences. My fascination with both chemistry and artificial intelligence technologies had been pushing me to seek a doctoral position in deep learning for drug discovery. My training at the Faculty of Fundamental Physical and Chemical Engineering at the Lomonosov Moscow State University, two years of experience as a software developer and an internship at the Skolkovo Institute of Science and Technology in Moscow allowed me to apply for my current position within AIDD.
The main area of my research is reaction product prediction and on organic reaction modeling in general. At the moment I am focused on exploring the strengths and limitations of transformer-based architectures for that purpose. The models that reliably predict products for given reactants or possible reagents for a reaction are of crucial importance for the success of computer-aided synthesis planning systems. Combined with the work of other AIDD fellows within the "One Chemistry" model, my contribution will allow to develop more powerful and reliable synthesis planning solutions for the pharmaceutical industry.
