Assistant Professor

Anita Koshy earned her M.D. from Duke University and trained clinically prior to her postdoctoral fellowship in molecular parasitology at Stanford University in the lab of John Boothroyd. During her time in the Boothroyd lab, she established an in vivo system that permanently marks and tracking the host cells that have interacted with the parasite Toxoplasma gondii. Anita started her lab at the University of Arizona in 2012. 

Research Technician

Carla received her bachelor’s degree from California University of Pennsylvania in California, Pennsylvania. Prior to working in research, Carla was a Certified Veterinary Technician for 10 years specializing in emergency medicine. Carla joined the Neurology Department at The University of Arizona in 2011, where she primarily focused on characterizing a mouse model of ALS. In 2012, Carla joined the Koshy lab and quickly became an integral part of multiple projects, including understanding the neuron-parasite interaction at the cellular and molecular level and the Alzheimer’s disease project.

Kathryn earned her B.S. in Biochemistry and Molecular Biology at UC Davis.  After graduating she worked as a technician, first in the lab of Dr. Robert Fairclough at UCD studying the pathogenesis of Myasthenia Gravis, and then in the lab of Dr. Nevan Krogan at UCSF studying the protein interactions between HIV and its host cell.  Kathryn earned her Ph. D. at UC Riverside under the guidance of Dr. Emma Wilson studying T cell migration behavior in the T. gondii infected brain.  In the Koshy Lab, she continues to study how Toxoplasma changes the brain and how those changes may alter the pathology of Alzheimer's Disease.

Arun received his doctorate from University of Hyderabad, India. He worked on the molecular and immunological aspects of Leishmania donovani infection. He joined the Koshy lab as Postdoctoral research associate and will be working on transcriptional profiling of individual neurons which have interacted with Type II and Type III Toxoplasma parasites.

Graduate Student

Josh earned his Bachelors in Microbiology at the University of Arizona. He joined the Koshy Lab as a graduate student in Molecular and Cellular Biology in 2016. His graduate project involves characterizing and defining the molecular and genetic elements that result in Toxoplasma strain-specific CNS immune responses with a particular interest in two secreted effectors, rhoptry protein 16 (ROP16) and dense granule protein 15 (GRA15).

Graduate Student

Oscar graduated from the University of California, Irvine in 2012. He subsequently worked at UCI in the lab of Aileen Anderson, where he worked on the role of different immune and brain molecules in recovery from spinal cord injury. Oscar joined the Neuroscience program at the University of Arizona in 2014 and became a member of the Koshy lab in spring 2015. His graduate project entails determining why Toxoplasma gondii has a predilection for specific regions of the brain. 

Graduate Student, Koshy Lab

Emily graduated from North Carolina State University with a degree in Biochemistry in 2010. After working in an environmental chemistry company in Wilmington, NC, and a subsequent stay in genetics lab of Dr. Ann Stapleton at UNC-Wilmington, Emily applied for graduate school at the University of Arizona.  She joined the fun, yet stimulating Koshy lab in 2016. The focus of her research is to study how toxoplasma gondii infection modulates host pathways in Alzheimer's Disease.

Graduate Student

Shraddha earned her Bachelors in Science from Salem College. Before pursuing graduate studies, she worked as a research assistant in the lab of Dr. Frelinger, studying immune response to Francisella tularensis. In the Koshy lab, she is working on dissecting Toxoplasma strain-specific CNS immune responses. The goal of her thesis work is to use the mouse model of CNS toxoplasmosis to better understand how two different clinically relevant canonical strains of Toxoplasma (type II and type III) can cause different CNS outcomes.
