ISIE's 2024 Forum
Designing Flower Power: 
Exploring Visions for the 2029 & 2031 International Horticultural Expos

Friday, May 3rd
10:00am (EDT)

[Note: This event has past, but
stay tune: ISIE is working on an exciting Speaker Series for Fall 2024!]

The Institute for the Study of International Expositions (ISIE) announces its Spring 2024 Forum: Designing Flower Power: Exploring the Visions for the 2029 and 2031 International Horticultural Expos. The free half-day event will take place virtually via Zoom on Friday, May 3rd, starting at 10:00am EDT.  Pre-registration is required.

Designing Flower Power explores the creation of International Horticultural Exhibitions. Much more than floral shows, these global Bureau International des Expositions (BIE) events typically draw up to 20 million visitors and are recognized catalysts for profound infrastructure development — especially parks and gardens that become enduring public spaces — in their pursuit of a greener future.

The Forum will consist of approximately two hours of presentations followed by discussion. 

The International Association of Horticultural Producers (AIPH), the body that grants the rights to stage these BIE events, will be represented at the Forum by Treve Evans, senior international relations manager of AIPH. Evans will present the talk, The Greenest Shows on Earth, which focuses on the long-lasting legacies these events leave in their host cities.

Additionally, the teams behind the upcoming Expo 2029 (Korat, Thailand) and Expo 2031 (expected to be held in Minnesota, United States) will present their dynamic visions for these mega-events. Thailand’s theme, Nature and Greenery: Envisioning the Green Future, spotlights the country’s proficiency in blending technology with traditional wisdom to create sustainable horticultural and agricultural practices. The United States’ expo, with the theme Human/Nature: Where Humanity and Horticulture Meet, expects to build upon the current 55% of the country’s 125 million households that engage in gardening and aims to transform residents into plant- and climate-educated, globally minded citizens.

Dr. James Fortuna
Ph.D., University of St Andrews

Prior to joining the University of St Andrews, James taught within the Faculty of Humanities and Foreign Languages at Santa Fe College in Florida, USA and spent the 2016 academic year as a lecturer within the Faculty of Humanities at Manchester Community College in Connecticut, USA. He received a B.A. in History and English at West Virginia University before completing master’s degrees in Classics and History at Trinity College Dublin and the University of Cambridge, respectively. 


His research interests lie in the cultural, social, and diplomatic history of twentieth-century Europe and the United States, with a particular focus on the classically inflected architectural production of the interwar period and its relationship to the construction of national identity. He is especially interested in instances of creative or ideological transfer between states and the spaces or places in which this might have occurred. He also explores the extent to which various interpretations of cultural heritage came to influence the reimagined built environments of Fascist Italy, Nazi Germany, and the New Deal USA.


Through the generous support of the St Leonard’s College International Scholarship, his PhD dissertation further developed these interests under the supervision of the Institute for Transnational and Spatial History. In exploring the ways architectural form and urban design were deployed as tools of diplomacy at the several international exhibitions held between 1933-42, this project recasts the historical role played by the international expositions while investigating potential links between the ambassadorial, domestic, and even imperial elements of state-sponsored design throughout the interwar period.


Dr. Flavia Marcello
Professor of Architectural History, Swinburne University of Technology

Flavia is a world expert on the architecture and cultural production of the Italian Fascist period. She is a member of the Centre for Transformative Media Technologies and came to Swinburne in 2013 after a varied teaching career at Deakin and Melbourne Universities and Temple University's Rome Campus. She has also worked as Professional Development Manager at the Australian Institute of Architects and as Curriculum Development Consultant at Box Hill Institute.


While living and working in Rome she developed her expertise on the city and its 2000 + years of history, particularly in the architecture and urban planning of the Italian Fascist period. Her long-time interest in 1930s art and architecture was explored in her PhD (University of Sydney, 2003) and has continued to evolve throughout her academic career. Her areas of research include: exhibitions, architectural ephemera, spatial practice, the political uses of the Classical tradition, manifestations of fascist and anti-fascist ideology in monuments and public space. 


Her book Giuseppe Pagano. Design for Social Change in Fascist Italy was pubished with Intellect Press in January 2020. Most recently, she has been exploring the use of virtual reality as a method for architectural history. She teaches in the areas of design, history and theory with a particular focus on the inter-relationship between art and architecture, between design and health. She also conducts action research in the role of design to improve health outcomes. Design studios are used to explore new paradigms for aged care, in particular for people with dementia. She facilitates the 'Hit Submit', 'Draft don't Drift' and 'Grant It!' writing workshops with Simone Taffe and is a leader of the Career Development team within SWAN (Swinburne Women's Academic Network).
