Ann T. Tate, Ph.D.
I am an Assistant Professor in the Vanderbilt University Department of Biological Sciences (Jan. 2017 – present). My research focuses on understanding reciprocal ecological and evolutionary feedbacks between hosts and parasites, using a combination of theoretical and empirical approaches to zoom back and forth between the molecular details and the population level processes.
Before moving to Vanderbilt I was a USDA NIFA postdoctoral fellow in the Department of Biology and Biochemistry at the University of Houston, mentored by Tim Cooper. I completed my Ph.D. in Ecology and Evolutionary Biology at Princeton University (advised by Andrea L. Graham), and received my B.S. from Rice University.

I joined the Tate lab as a research assistant in October of 2022. I earned my bachelor’s degree in human physiology from the University of Minnesota in 2020. Thereafter, I received a master’s degree from Lipscomb University in biomolecular science. At Lipscomb I worked with C. elegans to study anthelmintic resistance under the guidance of Brian Ellis. Outside of the lab I enjoy reading, hanging out with my roommate’s cat, and exploring the city of Nashville. Contact: morgan.m.pfeffer@Vanderbilt.Edu
Arun Prakash, Ph.D.
I’m a postdoc in the Tate lab since Apr 2022. My research focus, very broadly – is to understand the evolutionary ecology of infectious diseases. I’m particularly interested in how individuals adaptively evolve with infections or against infections using experimental evolution, immunology, genetics, and genomics as primary tools. I’m currently researching how the development and genetic architecture of innate immune systems could influence host-parasite coevolution in flour beetles. Understanding the coevolutionary trajectories could lead to important insights into variation in disease outcomes. Before moving to Vanderbilt, I completed my doctoral studies in Evolutionary biology, Immunology and Infection research at the University of Edinburgh, UK (2018 – 2021) advised by Pedro Vale. My PhD work was on the innate immune regulation of disease tolerance and priming, mainly focusing on the negative immune regulators. For my Master’s thesis, I worked with Deepa Agashe, NCBS, Bengaluru, India. I’m proud to be a first-generation college graduate and continued my education despite my family, and friends constantly asking me – why I’m still in school. Contact: arun.prakash@Vanderbilt.edu
Allyson Ray, Ph.D.
I am a postdoctoral scholar since November 2022, broadly interested in the evolutionary interplay between pathogens / parasites and their hosts. In the Tate lab, I am investigating translation dynamics during the innate immune response of the Tribolium flour beetle. Prior to joining the lab, I completed my dual Bachelors in Molecular and Cellular Biology as well as Psychology from the University of Illinois, Urbana-Champaign, in 2016. There, I worked in Dr. Gene Robinson’s lab studying gene networks and honey bee (Apis mellifera) social behavior, and RNAi efficacy in viral infection. In 2022, I completed my Ph.D. at Penn State University under Dr.s Christina Grozinger and Jason Rasgon, integrating multiple aspects of bee biology, field collections, experimental evolution methods, and genomic approaches to investigate honey bee – deformed wing virus dynamics and evolution after the introduction of the parasitic Varroa destructor mite. Outside of lab, I enjoy coffee, cooking, and video games. Contact: firstname.lastname@example.org
Danial Asgari, Ph.D.
I joined Tate Lab as a postdoc in September 2023. I’m interested in the evolution of insect immune signaling pathways. Specifically, I’m interested in the role of negative regulators in shaping immune responses and host fitness
in stochastic environments. Currently, I use a combination of data analysis and theoretical approaches to study the diversity and evolution of regulatory feedback mechanisms in immune signaling pathways. I received my PhD
from the University of Houston where I researched the evolution of induced
and constitutive immune defenses in flies. Outside the lab, my interests are
poetry, philosophy, and the German language. Contact: email@example.com

As an undergraduate, I also worked on research projects in population genetics and organic chemistry. Contact: firstname.lastname@example.org
I am a Biological Sciences PhD student and NSF-GRFP Fellow who joined the Tate lab in spring 2024. I received my Bachelor of Science degree in Microbiology from the University of Maryland, College Park. I am broadly interested in host-pathogen interactions and pathogen virulence evolution and have previously worked with plant and insect disease model systems as an undergrad. I am currently working to investigate the influence of variable host immune systems on the evolution of bacterial pathogens. Outside of the lab, I enjoy traveling, watching movies and playing games with friends. Contact: Rayshaun.email@example.com
