Algorithmic bioinformatics
The goal of my work is to develop state-of-the-art algorithms in computational biology to analyze DNA and RNA molecules, and help solving problems in biology and medicine. This covers the following topics: high throughput sequencing, metagenomics, noncoding RNA, proteomics.

Adapter trimming in Nanopore reads: Porechop_ABI:
discovering unknown adapters in Oxford Nanopore Technology
sequencing reads for downstream trimming is published in
Bioinformatics Advances. Porechop_ABI is an extension of
the original well-known Porechop (R. Wick). The novelty is that it is able to infer the adapter sequences
from the raw reads, without any external information. The algorithm uses approximate k-mers and
assembly. We also maintain all other great functionalities of
