Mark has been working with glass as an engineering material and an artistic medium for over 15 years. He received a PhD in glass science and a BFA from the New York College of Ceramics at Alfred University. After an introduction to neon in 2002 his work became significantly neon based and explores duration, motion, and alteration. He taught neon classes at Pilchuck Glass School and Brooklyn Glass with a decade of experience helping artists learn neon at Alfred. Philadelphia is his home base where he works at Heraeus Precious Metals developing glasses for silver pastes in high efficiency silicon solar cells.
