Sahar Al Seesi’s research interest is in bioinformatics. She works on developing algorithms to analyze next-generation sequencing data. Al Seesi works on various interrelated problems, including RNA transcriptome reconstruction, allele specific isoform expression estimation, gene differential expression and cancer specific mutation identification. Tackling each of these problems requires employing a combination of computational approaches such as machine learning, grammatical modeling, statistical analysis, parallel algorithms, dynamic programming and expectation maximization algorithms.
