Research Experience
Dedicated to investigating strain diversity in the model organism Vibrio fischeri and understanding the molecular basis that drive the microbial interactions within a system and how that impacts the host-microbe interactions in vivo .
Investigated the inhibitory effects of Type VI Secretion System (T6SS) positive Vibrio fischeri strains FQ-A001 and ANM004.
Created a Zucchini Yellow Mosaic Virus (ZYMV) positive plasmid that will be used in a diagnostic RT-qPCR assay, allowing for the tracking of the virus as the plant grows and the disease state develops.
1) Properly create a recombinant plasmid and screen for the desired plasmid construct
2) Design primers used for amplifying a gene segment of ZYMV with sticky ends, allowing for proper ligation
3) Effective work with RNA

(2026). Type VI secretion drives reciprocal growth inhibition among symbiotic Vibrio fischeri strains [Manuscript submitted for publication, Under Review]
I am a second-year graduate student in the Biochemistry, Microbiology, and Molecular Biology (BMMB) program at Penn State University, working in the lab of Dr. Tim Miyashiro. I am interested in molecular-scale mechanisms of interference competition, how strain-level variations drive community assembly, and host-microbe symbiosis. My research investigates how - competitive inhibition shapes microbial community composition, using the Vibrio fischeri Euprymna scolopes (Hawaiian bobtail squid) symbiosis as a model. V. fischeri colonizes the squid’s light organ in a competitive process, and my work focuses on the role of the Type VI Secretion System (T6SS) in mediating that colonization.
My current project centers on a newly identified class of PAAR domain-containing tip proteins of the T6SS. PAAR proteins sit at the tip of the T6SS apparatus and are thought to determine effector loading. I am working to define how the different domains of this newly identified protein interact with specific effectors and toxins and how those interactions influence T6SS assembly, activity, and ecological function during host colonization.
