Anastasia Levitin, PhDResearch Assistant Professor
Infection and Immunity, Antibiotic Resistance, Development of High-Throughput Screening Assays, Genetics, Microbiology, Molecular Biology and Biochemistry
Dr. Levitin received her undergraduate degree in biochemistry and her PhD in biology at Concordia University, Montreal, Canada. Her postdoctoral studies were done at National Research Council of Canada and at Stanford University School of Medicine.
Dr. Levitin is interested in studying host immune response to bacterial / fungal infections and defining biomarkers for rapid detection of microbial infection, as well as developing vaccines for prevention of infection.
Students will be exposed to the conceptual foundations of biotechnology and the role played by discoveries and applications of molecular biology principles in advancing biotechnology horizons. This is a case-based course in which students will read landmark original papers and patents that shaped biotechnology, and discuss these in the class.

Dr. Levitin has previously established the fruit fly Drosophila melanogaster macrophage-like cell line as a model to study host innate immune response to fungal pathogens, as well as transcriptional profiling of the pathogen response to host macrophages.
CURRENT RESEARCH PROJECTS:
Immune response to bacterial infections using Drosophila as a model organism
Innate immune response is a first defense against pathogens and it is evolutionarily highly conserved. The fruit fly Drosophila is devoid of an adaptive immune system, making this a model organism to study innate immune response to microbial infections. Dr. Levitin identifies components of innate immunity using Drosophila as a surrogate, and subsequently confirms the findings in mammalian systems.
Her lab also studies host genes differentially expressed in response to microbial infection that encode surface proteins since they are potential candidates for the development of biomarkers.
Dr. Levitin is also interested in pathogen genes encoding surface proteins that are differentially expressed in response to phagocytes. These genes represent targets for vaccine development.
