Dear Bev and family, I was so sorry to hear of your loss.  I worked with Mark at Colworth for a number of years.  He was always so professional and knowledgeable, a true expert and champion of cryo SEM.  He contributed so much understanding to Unilever’s Ice Cream business and beyond.  He took such pride in his work.  He will be greatly missed and many of Mark’s friends and colleagues will feel your pain.  Thinking of you so very much.  Sincere condolences, Stella
