Ryan studied architecture at Cornell University. Originally from Chicago, he has been based in Dublin, Ireland since 2002, establishing his practice in 2007. He has taught architecture at University College Dublin and the Dublin School of Architecture where he is currently a lecturer. 
The practice is primarily concerned with the creation of a careful and timeless architecture. The work explores the expressive potential of explicitly tectonic spaces where structure, making and place are central, avoiding the contemporary trend towards novel form. We are interested in creating characterful rooms and it is often in the display of naked structure, undisguised material or the traces of making which impart the unique atmosphere and sense of permanence which distinguish the spaces we create. 
The work is founded on the idea that an intelligent and engaging contemporary architecture must arise from an informed and often close reading of history and traditional building culture. 
The practice received the 2011 Royal Institute of Architects of Ireland award for the Best Emerging Practice in Ireland.
