“We Build Toys. Some Toys Change the World.” – N.N.T.
John’s research focuses on mosquitoes and an obligate intracellular organism, Wolbachia. Wolbachia lives in insect gonads and sterilizes sperm. John’s goal is to develop novel biotechnology approaches to combat arthropod pests. John’s research has won multiple awards, grants, and patents and has been published in high impact journals such as Nature, Nature Microbiology, and Insect Biochemistry and Molecular Biology. His research has been highlighted by popular news outlets including Wired, The Scientist, and Nature News and Views.
Wolbachia induce conditional sterility in insects called cytoplasmic incompatibility (CI). CI is used for direct suppression of insects via the sterile insect technique (SIT). SIT is the release of large numbers of sterile males to outcompete for mating with females. Ecologically, SIT drives down species-specific target populations and avoids pesticides. Endogenous CI is also a potent natural gene drive capable of transforming insect populations. Our research focuses on understanding the molecular mechanisms underlying CI.
To develop novel biotechnologies for transforming wild insect populations our lab uses advanced molecular biology to build and implement genetic modification of insects. Our research focuses on mosquito and Drosophila transgenesis using transposon based genome integrations. We also utilize CRISPR/cas9 based nucleases to evaluate insect genetics.
Our lab also studies bacterial effector proteins from obligate intracellular organisms that cause epidemic typhus, scrub typhus, and rocky mountain spotted fever. All these diseases are transmitted by arthropods. Understanding genes that facilitate microbial/host interactions in both humans and arthropod systems are of paramount importance.
