I am so sorry to hear the news, you are greatly missed by everyone at the UH. I remember when I used to invite you to give a lesson about 3D printing to my students. Not only did you really know your field, you were just one of those calm delightful people that gave the best lecturers, it was like story time mixed with Ted talks I did not want the lecturer to stop. I can see why you were nominated and won so many awards at the UH. I did not say good bye to you at work, so good bye my friend and rest in peace.
