Soil & Plant Microbiome Scientist | AMR/Resistome Analytics | Metagenomics | Plant–Microbe Interactions |

Profile Summary

I am a PhD-trained microbiologist and postdoctoral researcher specialising in One Health microbiome questions, with a focus on antimicrobial resistance (AMR) and resistomes across soil, water/wastewater, and plant-associated systems. I help academic and industry clients translate sequencing and metadata into defensible biological conclusions using reproducible bioinformatics and robust microbial ecology statistics. My core services include: (i) microbiome and metagenomics workflow design and troubleshooting (local or HPC), (ii) resistome/ARG profiling and interpretation, (iii) community ecology and biostatistics in R (alpha/beta diversity, ordination, PERMANOVA with dispersion checks, differential abundance, and clear visualisation), and (iv) manuscript-ready deliverables, publication-quality figures/tables, transparent reporting, and methods/results writing support based strictly on your outputs. I work well with complex experimental designs common in agriculture and environmental studies (e.g., treatment × compartment × time) and can support projects ranging from pilot studies to multi-site datasets. Engagements are milestone-driven, with an initial analysis plan, reproducible scripts, and organised outputs to ensure your team can rerun or extend the work. I am comfortable collaborating under confidentiality and will maintain high standards for scientific integrity and reporting.
