Experience

Researcher/Software Engineer

Jun 2011 - Sep 2013 (2 years)

Developing SPAdes genome assembler , which was one of the first genome assemblers, specified for single-cell bacterial data. Duties particularly included preparing current release using C++, also optimizing time and memory consumption. In addition a set of tools for an assembly quality assessment was developed using Java and Python.

Education

MS in mathematics

2008 - 2013 (5 years)

The lion's share of bacteria in various environments cannot be cloned in the laboratory and thus cannot be sequenced using existing technologies. A major goal of single-cell genomics is to complement gene-centric metagenomic data with whole-genome assemblies of uncultivated organisms. Assembly of single-cell data is challenging because of highly non-uniform read coverage as well as elevated levels of sequencing errors and chimeric reads. We describe SPAdes, a new assembler for both single-cell and standard

Jigsaw puzzles were originally constructed by painting a picture on a rectangular piece of wood and further cutting it into smaller pieces with a jigsaw. The Jigsaw Puzzle Problem is to find an arrangement of these pieces that fills up the rectangle in such a way that neighboring pieces have “matching” boundaries with respect to color and texture. While the general Jigsaw Puzzle Problem is NP-complete [6], we discuss its simpler version (called Rectangle Puzzle Problem) and study the rectangle graphs, recen
