Academic interests

I have a broad range of academic interests including molecular biology, bioinformatics, several omics studies, structural biology, phylogenetics and so on. I have an increasing interest in my current field of study, which is transcriptional regulation and post translational modification, particularly SUMOylation. I have always been highly interested in interdisciplinary field of research and my current position is a great opportunity to entertain my long held interest. In my study I combine both molecular biological techniques (wet lab approach) as well as several bioinformatic analyses (dry lab approaches). Some of the bioinformatics approaches that I frequently use include

  • Genome wide analyses
    • Analysis of transcriptomic data (RNAseq)
    • Analysis of epigenomic data (ATACseq, ChIPseq)
  • 3D-structure prediction of proteins
  • Integration of protein structural information and evolutionary sequence conservation for identifying functionally important residues
  • Sequence evolutionary conservation and phylogeny 

Background

I have a B.Sc in Biology (Genetics and Molecular biology) from Ambo University in Ethiopia and an M.Sc in Biotechnology from Addis Ababa University in Ethiopia. I have a second masters degree in Molecular Biosciences with a project in Applied and structural bioinformatics that I obtained from department of Biosciences at the University of Oslo.
