bkk UNZINE sat down for an interview with our own Estelle Cruz, architect & PhD in Ecology and postdoctoral researcher at Chulalongkorn University. Estelle is an exceptionally talented and driven artist, and we could think of no better person to kick off this series of interviews focusing on artists and their passions.

Primary among your passions is biodiversity. For our audience, can you speak to your background and the meaning of biodiversity, especially in relation to art… as well as architecture and design? Let’s start with biodiversity…

Biodiversity refers to the variety of life on Earth, encompassing different species of plants, animals, fungi, and microorganisms, as well as the ecosystems they form and the genetic diversity within them. It plays a crucial role in maintaining ecological balance and supporting life.

Why is biodiversity important in Thailand?

Thailand is a biodiversity hotspot, home to approximately 10% of the world's species. However, rapid urbanization, deforestation, and climate change threaten its ecosystems. Conservation efforts are crucial to preserving endemic species and maintaining ecological balance.

And on a global scale?

Globally, biodiversity is in decline due to habitat destruction, climate change, and pollution. Scientists warn of a sixth mass extinction, emphasizing the urgent need for conservation strategies, sustainable development, and policies integrating biodiversity protection.

To bring this back to a personal scale, how does your own background connect to biodiversity?

As both an architect and a researcher in ecology, I am deeply interested in sustainable architecture. I graduated as an architect from ENSAL Lyon in France and later pursued a PhD in ecology at the Museum of Natural History in Paris[1] with the CEEBIOS - Centre of Research and Studies in Biomimicry.

Biodiversity and sustainable architecture are the guiding themes of my work! Urban expansion reduces natural habitats, leading to biodiversity loss. However, architecture can also foster a strong relationship with nature by integrating plants, animals, fungi, and microorganisms into built environments. New generations of buildings take inspiration from nature for passive cooling systems, adaptive building skins, and sustainable urban design.

Could you tell us more about the artwork you submitted to be part of bkk UNZINE’s group exhibition Passion?

This artwork, combines three of my research passions: biodiversity, architecture, and comics.

It is an A3 comic panel celebrating the beauty of biodiversity and the architecture of the Museum of Confluences in the city of Lyon in France. The piece highlights the iconic design by the Austrian architectural studio Coop Himmelb(l)au, while showcasing various plant and animal species found in Lyon.

How did you choose the species you drew? Are these species found in the museum?

Well, I believe so! However, I specifically illustrated 16 species that are found near the Musée des Confluences. I used the app iNaturalist, a global citizen science platform where users photograph and identify plants, animals, and fungi. The online community then verifies the identifications, creating an extensive open-access database.

The website and application iNaturalist allows users to see species found in specific locations.

You’re clearly passionate about your work. What inspired you to follow this path, and what keeps you going?

As an ecologist, I see a vast gap between the alarming rate of biodiversity collapse and the current efforts of the building sector to address this crisis. This gap is immense, and the road ahead is long. Scientists have been warning governments since the 1970s—starting with the Limits to Growth report by Meadows et al. 1972[2]—yet we are still not acting fast enough.

I wonder if art can help bridge this gap. Can we speak to people’s hearts instead of just their intellect? Can art transform the way we perceive biodiversity?

Ecology is often seen as a technical or economic constraint rather than an opportunity for a better life—with cleaner air, water, and healthier ecosystems. However, human life is deeply dependent on biodiversity for food, health, water, and overall well-being. We have forgotten to appreciate the beauty of species—their vivid colors, their adaptations to humidity, heat, and light variations. We have lost our sense of wonder at life’s diversity.

  

What drew you to Southeast Asia, and specifically Thailand, for your work?

Thailand is a biodiversity hotspot, meaning it hosts an exceptional variety of species, including many endemic ones. This region is crucial for global conservation efforts.

 My first visit to Thailand was in 2022 to participate in a scientific expedition in Nan with Serge Morand from Mahidol University. Then I came back with Nicolas Lainé (MNHN Paloc), Julien Claude (IRD), etc.

Thailand is globally recognized for its stunning biodiversity, particularly on its islands. Initially, I expected to see wildlife close to Bangkok. However, I soon realized that spotting rich endemic biodiversity often requires traveling long distances—sometimes 12 hours by van to Nan or Phuket. Like many Europeans, I initially had a romanticized vision of Southeast Asian biodiversity.

Did you experience any culture shock when moving to Thailand? Any fun anecdotes?

I was amazed by Bangkok’s vibrant art scene. The city has over 80 art galleries, with exhibitions changing frequently at venues like the BACC, the Bangkok Art and Culture Centre.

Bangkok has a dynamic community of Thai and international artists, with collectives such as bkk UNZINE, Triplet Art Group, and The Hechyeomoyeo.

During my last four months in Thailand, I had the opportunity to exhibit my work six times—both in solo and group shows! It wouldn’t… couldn’t… happen like this in France!

Can you explain a bit more about your Fluorescence series?

The Fluorescence series was created in collaboration with Université Paris Cité and the LEM (Laboratoire d'Électrochimie Moléculaire), with Professors Bernd Schöllhorn and Serge Berthier in Vietnam.

This series explores an unseen world—the way insects perceive UV light and the fluorescence of plants. Some fluorescent patterns on flowers guide insects toward pollen and nectar. Humans can observe these patterns using blacklight torches to expose plants to UV light.

In 2021 researchers have discovered an exceptionally bright fluorescent biomatter when exploring, with UV-A light, the nests of several oriental paper wasp species of the genus Polistes, a genus of diurnal social insects[3]. I collaborate with these researchers to explain their methods and research process to study these biomatter.

This work is part of a graphic novel that tells the story of ecological research in Southeast Asia. The comic book will be published in English, Thai, and French in collaboration with Thai and Vietnamese research labs.

I am very happy that the artwork Fluorescence of Cuc Phuong won first prize in the scientific illustration competition organized by the research platform PEERef.

What is your ultimate dream for your work?

I have a dream that is already starting to come true! I want my art to actively support biodiversity conservation, and I have begun selling my artwork to fund conservation initiatives. I donate 50% of my sales to NGOs working in conservation, such as BCST (Bird Conservation Society of Thailand), WildAct Vietnam, Anoulak in Laos, etc.

I deeply believe that art can drive positive change for biodiversity. One day, I hope to open a community art gallery in Paris in collaboration with institutions such as the Museum of Natural History, IUCN and UNESCO. Let’s dream big and collectively for biodiversity conservation!


Estelle’s original artwork from the Fluorescence series, including the award-winning piece Fluorescence of Cuc Phuong, is currently on display at our gallery space, UNZINE 95, located at 180 Soi Sukhumvit 95 (near BTS Bang Chak station).

Come back next week for the following interview in this series, with issue 52’s featured artist Claire Chang.
