Chaeyun Kang
Research Assistant
I am a research assistant in the Charles Lab working on plant growth promoting Pseudomonas strains. My work focuses on characterizing the molecular basis of plant growth promotion in Pseudomonas strains MBI-RS1 and MBI-RS2. I study gene expression patterns associated with plant beneficial traits and integrate genes into other Pseudomonas strains to evaluate their function and contribution to plant-microbe interactions.

Noah Bailey
Honours Thesis Student
Honours thesis student investigating a low copy plasmid system for Pseudomonas putida KT2440 based on the environmental plasmid pWW0. Building on previous work which saw construction of a plasmid system including a minimal replicon and partitioning genes, my project is focused on evaluating expression and cloning ability of the vector alongside plasmid segregational stability testing.
Kelli Cheung
Honours Thesis Student
My name is Kelli Cheung and I am in my last term of Science and Business, specialized in Biology. My research project is looking at antimicrobial resistance of Pseudomonas in wastewater samples. Library clones that were resistant to the antibiotic Aztreonam were phenotypically screened into an E.coli host and Nanopore sequencing will be conducted.

Eugenia Dadzie
PhD Candidate
Eugenia’s research focuses on petrochemical plastics biodegradation. Her goal is to engineer Pseudomonas putida strains capable of degrading polyethylene terephthalate (PET) plastics as well as utilize PET plastics as feedstock for the production of PHA bioplastics. She is also pursuing an MBET degree.
ZiYu Kuang, MSc
PhD Student
Su-Hyun Kwon
MSc Student
Hi everyone! I’m Su, a MSc student in the Charles Lab. My research focuses on functional metagenomics discovering novel antimicrobial resistance genes in Agrobacterium pathogen using Wastewater DNA libraries
Zjardyn Liera-Hood, M. Binf.
PhD Candidate
Zjardyn is a PhD candidate in the Charles and Hug Lab. He completed his B.Sc. in Genetics and a course-based Master’s in Bioinformatics at the University of Guelph. His research combines bioinformatics, microbial ecology, and machine learning, and he enjoys complementing his computational work with wet lab microbiology.
Zjardyn’s research focuses on plastic biodegradation in Rhodococcus species. He also leverages his background in molecular genetics and bioinformatics to understand the effects of microplastics in freshwater ecosystems.
Minghui Ma
PhD Candidate
Currently working on developing and implementing a versatile nanoparticle-based immunodetection system to reduce the concentration/enrichment time and enhance the detection sensitivity of E. coli in water systems. This user-friendly detection method only requires a magnetic field and a spectrometer, which makes it applicable in diverse geographical locations, especially where facilities are limited.
Ally Miners
PhD Student
Ally Miners is a PhD student in the Charles Lab focusing on plant-microbe interactions. She began at UWaterloo in her undergrad in 2018 and transferred from her MSc to PhD in 2025. Ally is passionate about working in a multidisciplinary field and hopes to commercialize her research in the future. Her work focuses on optimization of microbial inoculants to improve plant stress tolerance. By applying plant growth-promoting bacteria (PGPB) she hopes to mitigate drought stress in field soybean as well as disease pressure in hydroponic tomato.
