Nadia Knudsen undertook a course in archaeological illustration at Birkbeck College, London after completing her undergraduate degree, which allowed her to pursue a freelance career within archaeology while bringing up her family. During this period, she was also involved with projects based at Cambridge County Council Archaeological Field Unit (now Oxford Archaeology East). She provided illustrations for various specialists, local archaeological groups and PhD students. Later contracts included Verulamium Museum in St Albans, Hertfordshire and she gained experience drawing skeletal material for the Museum of South Australia. Overall, her focus has primarily been the illustration of small finds in a wide variety of media (lithics, metals, ceramics and organic materials) as well as plans and sections.
In 2010 she undertook the MA program at the Institute of Archaeology, UCL. This course, and contacts which evolved from it, led to further opportunities within illustration and archaeological field work, including invitations to join the staff of the Shahrizor Prehistory Project, Iraq (Institute of Archaeology, UCL) and the Jezreel Valley Regional Project, Israel (University of Hawai'i, affiliated with Tel Megiddo, University of Tel Aviv). She gained further experience from excavation seasons at Tel Bet Yerah, Israel (affiliated with UCL and University of Tel Aviv).
