Molecular and genomic evolution
Statistical Methods for Studying Molecular Evolutionary Genetics
Various statistical methods are required to analyze and interpret data on molecular evolution. One of my research projects focuses on developing such methods. We are working on methods for inferring phylogenetic trees from various molecular data and estimating the number of nucleotide or amino acid substitutions between different sequences. We are also studying statistical methods for identifying different multigene families from genome sequence data.
Evolutionary Studies of Genomic Sequence Data
Genomic sequence data provide important information on the evolution of genes and phenotypic characters. Currently, we are studying the molecular basis of evolution of morphological and physiological characters such as olfaction and other sensory systems in vertebrates and flower development in plants. Our approach is to compile genomic gene sequences from various organisms and to study how the DNA sequences, the number of genes involved, and the interaction of component multigene families have changed in the evolutionary process. The genetic systems we are studying now include the sensory systems and immune systems in vertebrates and the flowering system (MADS-box genes) in plants.
In the past couple of decades we have studied the evolutionary changes of genomic sequences of various organisms to examine the importance of genic and chromosomal mutations in morphological evolution and speciation. This is a long-term project and is ongoing.
