Jill organised and hosted the conference ‘Repton and Horticulture’, part of the Gardens Trust’s Celebrating Humphry Repton initiative, at the Dorothy Fox Education Centre at Sheffield Botanical Gardens on 20-21 September 2018, and subsequently co-wrote the preface to the Garden History special edition which published the conference proceedings.
She spoke at the ICOMOS conference “Filling the Gaps: World Heritage and the 20th Century” in Chandigarh on 3-4 October 2013. At a session dedicated to historic urban landscapes of the 20th century, she analysed the treatment of Dan Kiley’s 1960s design for the North Court at Lincoln Center in New York City. This seminal work was neglected, damaged and then effectively dismantled in 2010.
She was invited to present a paper “’For beauty, and air, and view’: contemplating the wider surroundings of sixteenth-century Mughal and European gardens” as part of the panel on Islamic and Renaissance Gardens: A Case for Mutual Influence? at the second international meeting of the European Architectural History Network, held in Brussels, 31 May-3 June 2012.
In March 2011, she was one of the speakers at the symposium Foreign Trends on American Soil, at the University of Pennsylvania School of Design. Her paper was “ ‘These beautiful pleasure-grounds of Death’: cross-cultural comparisons of values and meaning in the inceptive responses to the Parisian garden cemetery and its American interpretation.”
