Phylogenetics is a topical and growing area of research. Phylogenies phylogenetic trees and networks allow biologists to study and graph evolutionary relationships between example of phylogeny in biology species. These are also used to investigate other evolutionary what are the social change theories - for example, how languages developed or how different strains of a virus such as HIV or influenza are related to each other.

Book Description This self-contained book addresses the underlying mathematical theory behind the analysis of phylogenies. The theory is grounded in classical concepts from discrete maths and probability theory as well as techniques from other branches of maths algebra, topology, differential equations. The biological relevance of results is highlighted throughout. His research interests include combinatorics and random processes and their applications to questions in evolutionary biology and related areas of sciences, which who should a taurus never marry biology have mainly concerned phylogenetic theory and methods.

Additional research interests include autocatalytic networks in origin of life, inverting random functions in mathematical statistics, and questions in the philosophy of science concerning causality and information loss. He has published approximately academic papers, co-authored two books on phylogenetics, and served as associate editor of various journals, including Bulletin of Mathematical Biology and Systematic Biology.
