Overview of Research
Nothing in biology makes sense except in the light of evolution. It is especially important to understand the diversity and generality of living organisms on the earth and complex life phenomena. Mathematical models allow us to determine which evolutionary transitions are plausible and which are inaccessible. Currently, we are focusing on the following research themes.
(i) Genomics and speciation theory for non-model organisms
(ii) Fitness landscape theory that connects genotype, phenotype, and fitness and analysis of evolutionary experiments
(iii) Predicting the dynamics of viral infectious diseases using evolutionary ecology theory
Mathematical biology fits widely into various fields of biological sciences with bioinformatics analysis, and we would like to contribute to life sciences from evolutionry aspects.
