I had the great pleasure of knowing Raj since I began as a PhD student at the University of Strathclyde in 1991. He was a supervisor of another PhD student funded by the same company (Reyrolle Protection) and I worked together with the Bath team during my PhD and have visited several times (including my first conference – UPEC – back in 1992). Raj and I remained colleagues and friends over the years – examining each others’ students and working together on conference committees, and Raj was always a great contributor and an excellent researcher. He will be greatly missed and fondly remembered, and I would like to pass on my concolences to all of his friends and family.
