About me

I am a Machine Learning engineer at Kaiko.AI, where I develop self-supervised and supervised Machine Learning methods for clinical pathology. I focus on building foundation models for pathology images and RNA-Seq data to help hospitals with diagnostics and other types of clinical problems.

I completed my PhD at ETH Zurich, where I designed novel algorithms and compressed data structures for indexing huge collections of biological sequences and developed methods scalable to the entire Sequence Read Archive. These methods finally made this trove of data accessible for search by sequence at scale and demonstrated the feasibility of making all of life's code easily searchable.

Prior, I studied Math, Physics, CS, and Machine Learning at MIPT, Skoltech, and YSDA and worked on a few problems of computational structural biology at Inria Grenoble-Rhône-Alpes.

Projects

Ocean Microbiomics Database
Collaboration with Sunagawa Lab. Provided k-mer based sequence search and Counting de Bruijn graph indexes for the Genome Collection of the Ocean Microbiomics Database. Other contributors: Lucas Paoli, Harun Mustafa, Andre Kahles. (Published in Nature).

Ocean Microbiomics Database
MetaGraph
A C++ framework library for indexing very large collections of DNA/Protein sequences and a tool for sequence search, alignment, and assembly. Although the target use cases of MetaGraph overlap with BLAST, MetaGraph mainly focuses on the scalable indexing of raw sequencing data in annotated de Bruijn graphs with up to $\sim 10^{12}$ nodes and $\sim 10^{7}$ annotation labels. It also provides an online platform MetaGraph Online. Other contributors: Marc Zimmermann, Thomas Zhou, the MetaGraph team.

GeoDNA
A portal for sequence search and geographical positioning based on the metagenomic MetaSUB data. The initial prototype was set up on a weekend but it served well and was also used as a base for the MetaGraph Search platform. Other contributors: Marc Zimmermann, Jiayu Chen, André Kahles, Thomas Zhou. (Published in Cell).
