Hi there :)

My name is Alex, and I am a bioinformatics professional with a doctoral degree in the field of transcriptome bioinformatics. My research project focused on disclosing the functions and evolution of lncRNAs.

I possess extensive experience in designing and implementing high-performance bioinformatics systems to store, process, harmonize, and analyze sequencing data of different modalities, such as RNA-Seq, WGS, WES, and gene panels. I am also familiar with data processing at scale using HPCs and AWS cloud infrastructure.

In industry, my work primarily revolves around designing and implementing bioinformatics solutions and data-processing pipelines, with a specific focus on gaining insights from sequencing data in the fields of cancer biology and drug discovery. My main responsibility is translating biological questions into technical tasks and designing the appropriate approach to deliver results and interpretations within a reasonable time and budget. I place a strong emphasis on achieving results.

Another area of my expertise is data analysis, including statistical analysis, exploratory data analysis (EDA), data visualization, dimensionality reduction techniques, feature engineering, and machine learning.

    Education

    Department of Integrative genomics AMU, Poznan - PhD

    April 2015 - October 2021

    My doctoral thesis centers on revealing connections between structure, functions and evolution of long noncoding RNAs across 11 primates and human. The project includes transcriptome assembly, identification of non-coding transcripts, prediction of orthologs, statistical analysis and database building.
