Postdoctoral researcher in

I obtained my Ph.D. in Computer Science from the University of Helsinki in 2012. My Ph.D. supervisor was prof. Veli Mäkinen from the Genome-Scale Algorithmics group. I have received funding from Hecse doctoral programme, ALGODAN and Academy of Finland (three-year Academy of Finland postdoctoral grant starting from Sept 2015).
