Welcome to PhyloD
HIV, like most retroviruses, is characterized by a tremendous rate of mutation, which leads to a high level of genetic diversity within and among patients.
This genetic variation is the substrate for rapid within-host evolution. As our immune system learns to target the virus, the virus adapts, leading to an
endless game of cat-and-mouse. From a scientific perspective, this provides a useful opportunity: if HIV is constantly adapting to our individual immune responses,
then studying HIV adaptation will provide insights into both virus function and basic immunology. Over the years, Microsoft Research
has developed models of viral adaptation that
have allowed us to do just that. The tools we have developed for that purpose are provided as a service on this website. To download source code and executables,
