Henry studied for a Bachelor of Veterinary Medicine at the Royal Veterinary College (RVC), and graduated in 2018.
Research projects undertaken at university covered a range of avian and laboratory experience, including an investigation into the effects of biomass heating on prevalence of hock burn and pododermatitis in broilers, and culture of Helicobacter suis from porcine tissue.
Before qualifying, Henry undertook a variety of placements within the poultry industry, including at Crowshall Veterinary Services. He also undertook a placement with government veterinary services, namely at the APHA Heathrow centre.
In September 2018 Henry started work at Crowshall Veterinary Services LLP so he could pursue his interests in population medicine, practical flock health planning, and veterinary public health.
