Before infecting humans, tick-borne bacteria or viruses first have to get past a tick’s defenses to colonize it. How this occurs is not well understood. To investigate, Yale researchers studied a model of the second-most-common tick-borne infection in the United States, human granulocytic anaplasmosis, which can cause headaches, muscle pain, and even death.

Biography
My research focus is on arthropod vector- host-pathogen interactions. I aim to understand at the molecular level how pathogen infection levels are sustained in arthropod vectors and what factors determine infection rates in arthropod vectors in endemic areas. Defining these factors might reveal ways to control vector-borne diseases.

Research
Overview
Dr. Narasimhan studies the molecular biology of tick-pathogen interactions that facilitate pathogen colonization of the tick and ultimately pathogen transmission to the vertebrate host. She is also expanding her research to gain molecular insights into the impact of climate change on tick-Borrelia interactions and infection rates in endemic areas.

- Ticks encounter microbes in multiple ways (in soil, leaf litter, host skin and host bloodmeal) . How some microbes colonize ,and some are cleared by the tick is an active area of research that could reveal new insights to control infection prevalence in ticks in endemic areas .
