Mark Shep­ard is an artist, ar­chi­tect and re­searcher whose post-dis­ci­pli­nary prac­tice ad­dresses new so­cial spaces and sig­ni­fy­ing struc­tures of con­tem­po­rary net­work cul­tures. His cur­rent re­search in­ves­ti­gates the im­pli­ca­tions of mo­bile and per­va­sive media, com­mu­ni­ca­tion and in­for­ma­tion tech­nolo­gies for ar­chi­tec­ture and ur­ban­ism. Re­cent work in­cludes Hertz­ian Rain, a vari­able event struc­ture de­signed to raise aware­ness of is­sues sur­round­ing the wire­less topog­ra­phy of urban en­vi­ron­ments through telem­atic con­ver­sa­tions based on sound and bod­ily move­ment; Sen­tient City Sur­vival Kit, a col­lec­tion of ar­ti­facts, spaces and media for sur­vival in the near-fu­ture Sen­tient City; and the Tac­ti­cal Sound Gar­den (TSG), an open source soft­ware plat­form for cul­ti­vat­ing vir­tual sound gar­dens in urban pub­lic space. His work has been ex­hib­ited at mu­se­ums, gal­leries and fes­ti­vals in­ter­na­tion­ally. In 2009, he cu­rated To­ward the Sen­tient City, an ex­hi­bi­tion of com­mis­sioned pro­jects that crit­i­cally ex­plored the evolv­ing re­la­tion­ship be­tween ubiq­ui­tous com­put­ing and the city. He is the ed­i­tor of Sen­tient City: ubiq­ui­tous com­put­ing, ar­chi­tec­ture and the fu­ture of urban space, pub­lished by the Ar­chi­tec­tural League of New York and MIT Press.
