Research interests in our research group

Our group is interested on the role of alternative splicing of the genes, introgression (interspecific gene flow) and chromosomal inversions in cold adaptation at the genomic level. We use Drosophila virlis group flies, namely D. montana, D. flavomontana and D. lummei as model species. We also investigate the effects of Trypanosoma parasites on mortality, locomotor activity and cold tolerance of the flies.
