Dr. Daniel Fisher's primary research interests are the dynamics of evolutionary processes. These include theoretical work on general issues and models in evolutionary dynamics, especially quantitative aspects, collaborations with experimental groups on laboratory evolution of microbes and on field studies of microbial diversity, improved methods for analysis of DNA sequence data to understand variations, and repertoire and dynamics of the immune system. Dynamics of cellular processes is also an active interest.

Dr. Fisher's lab is a group of researchers working to gain insights about and improve our understanding of biology through theory and modeling, spanning from abstract to concrete biological contexts. They also collaborate with a variety of groups carrying out laboratory experiments or trying to extract understanding from observational data.
