Su has been actively painting and exhibiting since she graduated from NSCD University in 1984. Her work is found in many public and private collections, including the NS Art Bank, Carleton University Art Gallery, City of Ottawa Art Collection, Canadian War Museum and others.
 
Much of her recent work has been centred on the fishery and its role in shaping lives in Nova Scotia. This has taken the shape of large format paintings as well as cabinets of curiosities.
 
Su has also done a massive amount of work on two large triptychs about her ancestry, maternal and paternal families back to their origins.

Su lives in Lunenburg, NS where she has a studio in her home.
