Adela Oliva Chavez, Ph.D. is an assistant professor in the Department of Entomology at Texas A&M University. Her interest focuses on the molecular host-pathogen and vector-pathogen interactions. She is interested in how vector-borne pathogens influence host and vector cellular responses, such as immune responses, cellular trafficking, and vesicle secretion. She is also interested in finding management alternatives to stop tick feeding and pathogen transmission in animal systems and in humans. She has published her research in several high impact journals, including Nature Communications, PNAS, PLoS Pathogens, and others. She has also contributed to a book chapter on “Protozoal and Rickettsial vaccines” in “Veterinary vaccines” by FAO and another on “Intracellular Pathogens II: Rickettsiales” in “The Way Forward: Improving Genetic Systems”. During her 3 years at Texas A&M University she has secured around $1M dollars in support of her research program as Principal Investigator (PI) and Co-Principal Investigator (Co-PI).
