Background
Zed Chen is a Postdoctoral Research Associate in quantitative genomics at the Roslin Institute, University of Edinburgh, working within the Highlander Lab under the supervision of Hannes Becher and Gregor Gorjanc. His research focuses on advancing the application of Ancestral Recombination Graphs (ARGs) in predictive plant breeding and genome editing, as part of the OptiME project.
Zed holds a PhD in Infectious Diseases and Immunology from the University of Edinburgh, where he developed reproducible NGS pipelines to analyse complex genomic and metagenomic datasets of microbial pathogens, contributing to diagnostic assay development and understanding of drug resistance. He also holds an MSc in Bioinformatics (with Merit) from the University of Edinburgh and a BA in Biology and Mathematics (Magna Cum Laude) from Bowdoin College.
Prior to his current role, Zed worked as a Bioinformatician at the Royal Botanic Garden Edinburgh, where he led data analysis on a Biodiversity Genomics Europe project, designed genome-wide barcode screening pipelines, and delivered over 30 hands-on workshops in bioinformatics to research staff and students. His earlier research included leading computational analyses for international collaborations in pathogen genomics, with contributions to five high-impact publications and presentations at five international conferences.
Zed is passionate about translating complex genomic questions into actionable insights and bridging the gap between method development and practical application in plant breeding. He is committed to reproducible research, open science, and training the next generation of researchers in quantitative genomics and bioinformatics.

The current work involves developing digital twin simulations of plant breeding programmes using AlphaSimR, inferring ARGs from real crop data using tsinfer and the wider tskit ecosystem, and evaluating ARG-based methods for genomic prediction, GWAS, and estimation of haplotype and mutation effects. He works closely with international collaborators across the University of Oxford, the University of Michigan, and the Allele Mining projects in maize, sorghum, rice, cassava, and cowpea, with a focus on establishing rice as the focal crop for this research.
