Research Interests

Our research focus is on the evolution of genes and genomes in the major human fungal pathogen Candida albicans and how these genetic changes contribute to phenotypic diversity.  C. albicans resides as a harmless commensal in the majority of people worldwide but is capable of causing superficial mucosal infections in otherwise healthy individuals as well as life-threatening systemic infections in patients with compromised immune systems.

 

Anderson Lab Research

Genetic basis of phenotypic diversity

Widespread phenotypic diversity is found among C. albicans clinical isolates, including variability in the extent of disease produced in insect and animal models of infection.  This variation is produced by massive genetic diversity between C. albicans strains, which is similar in magnitude to the nucleotide divergence between humans and chimpanzees.  We are working to identify the genetic basis for C. albicans phenotypic diversity and explore how individual polymorphisms affect host/pathogen interactions using combined quantitative genetic approaches.  Differential host response to C. albicans isolates remains an underexplored topic and our research will provide insight into how natural selection acts upon this variation in the context of commensalism and infection.

Expanded gene families in virulence

The telomere-associated (TLO) gene family has expanded significantly in C. albicans relative to less pathogenic Candida species.  These genes encode components of the Mediator complex, a key transcriptional regulator complex in eukaryotes.  Significant strain-to-strain variation in gene copy number exists for TLOs although the role of individual paralogs is unclear.  We are investigating the molecular and biological roles of individual TLO genes to understand what selective pressures exist to promote gene family expansion and evolution.

 

The role of eukaryotes in the human gut microbiome

Microbial eukaryotes are an integral component of human-associated microbiota but are often neglected in understanding the ecological framework of these host niches and in contributions towards health and disease. Species of fungi, protists, and helminths have all been identified within the human gut but there relative abundance across different populations and conditions remains unclear. We have recently developed a metagenomics approach to identify eukaryotes present at low abundances in complex microbial communities and are working to understand their role in community architecture in these niches and their importance towards human health.
