  • Research interests

    I studied Bioinformatics as I wanted to crack the code of the genomic content which is represented using only 4 letters. This led me to working with various animal models such as plants, insects and humans. I’ve performed various types of bioinformatic analyses which includes genome assembly, transcriptomic analyses and genomic analyses. I’ve mainly worked on different types of sequence analyses and now I’m trying to look into evolution with my previously acquired skills.

  • Current project

    I’m working on “Neo-sex chromosome evolution and dosage compensation in morabine grasshoppers”. The main goal is to characterise the extent of recombination suppression across Vandiemenella viatica species nascent sex chromosomes,  and to determine whether chromosome-wide dosage compensation or dosage-sensitive genes contribute to the maintenance of gene dosage on degenerate sex chromosomes and also how fast the Neo-Y degenerates after recombination suppression.
