I shared an office with Andy while we were both finishing our PhDs in Cardiff back in 2007. He was an all round excellent human being. I remember fondly his talk to the PhD cohort on short term memory for olfactory stimuli – he’d embedded a sound file of a person loudly and inelegantly sniffing into the slides and didn’t miss a single opportunity to play it, whenever the term ‘odour’ was mentioned. Mostly I just remember him being a very kind, very clever and very funny man, he will be greatly missed. My sincerest condolences to his family.
