2025-6 student placements now being advertised at ADAS!
Placements have played a key role in my career so far, giving lots of experience in different settings and learning new things, so I highly recommend, and there's plenty to get involved with at ADAS🌱

Thanks for your hard work for #NIAB over the last 13 or so years @WeedSciJohn and good luck for the future. Here's a couple of photos from this year's events to remember us by!

Well it's actually happening. After 13 years at NIAB I'm leaving at the end of the week to join my new @weedwiseuk colleagues at ADAS.
Wanted to thank my erstwhile @niabgroup colleagues who I've so enjoyed working alongside.
