We are excited that Tomasz Koralewski has joined our lab. Tomasz obtained his Ph.D. degree in the Department of Ecosystem Science and Management, Texas A&M University, in 2010. His previous research focused on comparative genomic analysis of adaptive and economic traits related genes in Southern pines. Being interested in human evolution, he is now on the prowl for signs of positive selection in the human genome. As said, the detection of changes in the sequences of particular genes from one population to the next can signal an adaptive value for those genes and thus indicate how humans are evolving through time. Welcome on board, Tomasz!
