Parasite Community Assembly and Transmission in Long-tailed Macaques

We use Geographic Information Systems and genetic tools to study how landscape features (i.e. physical, social and anthropogenic) and ecological drivers influence parasite community assembly and transmission in long-tailed macaques. As part of this effort, we evaluate prokaryotic and eukaryotic gut microbial communities and their interactions to understand factors that influence gut community diversity and stability.

Research Focus

  • Genetics and Genomics

    One way to study certain diseases is through genetics - the study of heredity and the variation of individual inherited genes in an organism. At the EIGH, this means studying how organisms can inherit and spread certain diseases. Additionally, by analyzing the entire structure, function, and evolution of an organism's genes, researchers may identify ways to prevent a disease from genetically passing disease traits.

  • Infectious Diseases

    At the EIGH, our researchers work to combat a number of various illnesses, including infectious diseases caused by organisms like bacteria, viruses, fungi, and parasites. These diseases can also be spread from one person to another and may be transmitted from animals to humans.
