I am studying the diversity of the gut microbiota in drosophilid flies and the influence of these bacteria on their fitness. I am combining the wealth of information available through modern metagenomic and transcriptome analysis with the power of Drosophila genetic experimentation to further our understanding of the mechanisms of interconnectedness of host and symbiont.

I do most of the ordering and I maintain the laboratory inventories of chemicals and other materials, and I am increasingly working in the laboratory too. Since I sent off my younger daughter to college, I am glad to find work after a long hibernation.

Bessem Chouaia

Postdoctoral Researcher

Email: bc335 [at]

I am a microbial ecologist with a focus on interactions between bacteria and arthropods. My research focuses on investigating metabolic pathways shared between insects and intracellular bacteria, and the mechanisms by which they are regulated, using metagenomics and metatranscriptomics tools…more

I am interested in metabolic interactions between aphids and their bacterial symbionts. Aphids feed on nutritionally poor diets and require symbionts that provide essential amino acids. Currently, I am investigating mechanistic basis of the nutritional phenotypes of aphids…more

Postdoctoral Researcher

I am interested in understanding the nutritional interaction between Drosophila and its gut microbiota, including how the microbiota protect the insect from hyperlipidemia and the underlying molecular mechanisms… more

Xiangfeng Jing

Postdoctoral Researcher

Email: xj43 [at]

My research mainly focuses on exploring the novel molecular targets in controlling phloem-feeding insects based on two characters of phloem-feeding insect pests: 1) feeding on phloem sap which contains high concentrations of sugars; 2) obligate relationships between insect hosts and their symbiotic bacteria.

Dan (GeonHo) Kim

Undergraduate Research Assistant

Email: gk334 [at]

I am an undergraduate student majoring in Entomology, and I joined the Douglas lab in January 2012. I am interested in animal behavior and physiology, especially of insects, and microbiology. For my Honors project, I am investigating the compounds produced by bacteria that promote oviposition by Drosophila.

Junbo Luan

Postdoctoral Researcher

I am interested in whitefly-symbiont interactions. Currently, I focus on the metabolic interactions between whiteflies and symbionts, with the goal to suppress whitefly population through disrupting the symbiosis…more

Yuan Luo

Postdoctoral Researcher

I have worked with Angela Douglas since October 2013. During the first year, I investigated the interactions between Drosophila and their gut bacteria to understand how the host affects the bacterial composition in the insect gut and in the food. In October 2014, I transferred to a project on plant-mediated RNAi in whitefly, funded by the Atkinson Center for Sustainable Future, with the goal to improve the efficiency of plant-mediated RNAi against whitefly genes.

Nathan Wynans

Undergraduate Research Assistant

I am an undergraduate student majoring in Biological Sciences with concentrations in microbiology and neurobiology. I joined the Douglas Lab in the Fall of 2013. I am interested in the effect microbes have on their host’s physiology and development. The project I am working on aims to sequence the genomes of representative Drosophila melanogaster and Drosophila suzukii gut microbes.
