Born in 1962, Paris. Lives in New York.
Huyghe’s works often present themselves as complex systems characterised by a wide range of life forms, inanimate things and technologies. His constructed organisms combine not only biological, technological and fictional elements, they also produce an immersive, constantly changing environment, in which humans, animals and nonbeings learn, evolve and grow. In 2001, he received a Special Award from the Jury of the Venice Biennale. He was also awarded the Solomon R. Guggenheim Museum’s Hugo Boss Prize in 2002. In 2017, Huyghe was awarded the Nasher Prize for Sculpture. Recent major projects /solo exhibitions include “UUmwelt” at the Serpentine Gallery, London (2018), “After Alife Ahead” at Skulptur Projekte Münster (2017), “The Roof Garden Commission” at the Metropolitan Museum of Art, New York(2015), “A Season Dedicated to Pierre Huyghe” at The Artist’s Institute, New York (2014). In 2013-2014, a major retrospective of Huyghe’s work traveled from the Centre Pompidou, Paris to the Ludwig Museum, Cologne and to Los Angeles County Museum of Art, California. His work has also been featured in group exhibitions including "Tino Sehgal" at the Palais de Tokyo, Paris (2016), "Saltwater: A Theory of Thought Forms" at the 14th Istanbul Biennial (2015), “documenta13” in Kassel (2012) among others.

- Ian Cheng
Born in 1984, Los Angeles. Lives in New York.
Cheng makes simulations that explore the nature of mutation and our capacity to relate to change. Drawing on principles of video game design, improve, and cognitive science, Cheng’s virtual ecosystems are populated with characters governed by competing models of artificial intelligence (AI). Each attempt to perpetuate its approach amidst otherworldly environmental conditions. What emerges is an endless, unpredictable stream of artificial life, at times familiar, uncertain, boring, surprising ̶ what Cheng calls “art with a nervous system.” Recent solo exhibitions include Serpentine Galleries, London (2018); MoMA PS1, New York (2017); Carnegie Museum of Art, Pittsburgh (2017); Migros Museum, Zürich (2016); Fondazione Sandretto Re Rebaudengo, Turin (2015); Pilar Corrias Gallery, London (2015), the Triennale di Milano (2014). Group exhibitions include Louisiana Museum, Copenhagen (2017); Yokohama Triennale (2017); Hirshhorn Museum and Sculpture Garden, Washington D.C. (2016); Whitney Museum of American Art, New York (2016); Taipei Biennale (2014); 12th Lyon Biennale (2013); Sculpture Center, New York (2012).

Melissa Dubbin: Born in 1976, Las Cruces, USA. Lives in New York.
Aaron S. Davidson: Born in 1971, Madison, USA. Lives in New York.
Dubbin and Davidson’s work has been described as addressing “processes of transmission and reception, interference and transference” often seeking to materialise immaterial or ephemeral states of matter (sound, light, air, time). They have co-authored a body of works producing forms, objects, images and experiences, equally incorporating the mediums of photography, video, sound, performance, sculpture and artists books since they began working together in 1998. Dubbin and Davidson were recently chosen as the first artists to participate in the year long artist-in-residence program of the Pinault Collection (2016). Recent solo exhibitions include Six Degrees of Freedom at Untilthen, Paris (2017), “Poétique des sciences”, Le Fresnoy, Tourcoing, France (2017), “Nobody Shoots a Broken Horn in Early Spring” at Campoli Presti, Paris (2016); Treize, Paris (2014); Audio Visual Arts (AVA), New York, (2013); Henie Onstad Kunstsenter, Høvikodden, Norway (2012); and Nýló, The Living Art Museum, Reykjavik, Iceland (2012). Recent group exhibitions include “Esma'/Listen” at Beirut Art Center (2016); “Bitter Sweet Symphony”, Untilthen, Paris (2016), Paris, Co-Workers, Bétonsalon, Paris (2015); “Some Artists’ Artists” at Marian Goodman Gallery, New York (2014); The Artist’s Institute, New York (2014); “Art of Its Own Making” at The Pulitzer Foundation for the Arts, St. Louis, MI (2014); “The String and the Mirror”, Lisa Cooley, New York (2013); “Alchemical”, Steven Kasher Gallery, New York, (2013); and Sound Spill, Zabludowicz Collection, New York (2013).

- John Gerrard
Born in 1974, Dublin. Lives in Ireland.
Gerrard produces simulation which explores structures of power and networks of energy that have coincided with the expansion of human endeavour in the past century. The works often feature geographically isolated locations such as the agrarian American Great Plains, the Mojave Desert’s solar plant, remote reaches of the Gobi Desert, or sites of military exercises in Djibouti. These simulations are non-durational, rendered in real time the programmed software unfolds over the course of annual cycles. In these works, documentary foundations find fictional realisations which examine scientific experimentation, industry, sustainability, and conditions of temporality. Recent major presentations include singular works presented outdoors on LED walls at Somerset House, London in 2017; LACMA, Los Angeles in 2018 and in Palm Springs as part of Desert X in 2019. Recent exhibitions include: “Long March Project: Building Code Violations III - Special Economic Zone”, Long March Space, Beijing, China (2018); “Manifesta 12 - The Planetary Garden. Cultivating Coexistence”, Palermo, Italy (2018); “Electricity”, Wellcome Collection, London, England (2017); “John Gerrard: Power, Play”, Ullens Centre for Contemporary Art, Beijing, China (2016); “Exercise”, Kunsthalle Darmstadt, Darmstadt, Germany (2015); “Solar Reverse”, Lincoln Center in association with the Public Art Fund, New York NY (2014). Forthcoming exhibitions include Galway International Arts Festival (2020), and Gwangju Biennale (2020).

Fabien Giraud: Born in 1980, France. Lives in Paris.
Raphaël Siboni: Born in 1981, France. Lives in Paris.
Their collaborative practice reflects on cinema history, philosophy, and technological evolution. Since 2014, they have been working on a long term, three fold project articulating films, performances, and sculptures in an exploration of technological history as an apparatus for our own uprooting. In 2018, the first part of this project entitled “The Unmanned” and composed of eight films was completed. Conceived as a history of computation told in reverse, it tried to go back in history and turn a technology devised to predict the future in a tool for the transformation of our past. Recently, they have initiated “The Everted Capital”, the second part of this project and conceived as performative speculation on the future of value. Their recent solo exhibitions include venues such as MONA, Australia (2018) and Casino-Luxembourg (2018). They have been involved in numerous group shows in venues such as Kunsthalle Wien, Wien, Austria (2019), Museo PallazoRiso, Parlermo, Italy (2015); Lyon Biennale (2015), Liverpool Biennial, United Kingdom(2016), Palais de Tokyo, Paris (2017) or VAC foundation, Venice, Italy (2017).

- Elizabeth Hénaff
Born in 1981, Austin, USA. Lives in New York.
Hénaff is a computational biologist and artist, exploring the porous boundaries between organisms and environments. This inquiry has produced a body of work that ranges from scientific articles in peer-reviewed journals, to design interventions and art exhibits. She has made contributions to understanding how plants respond to the force of gravity, how genome structure changes in response to stress, and most recently has turned her attention to the ubiquitous and invisible microbial component of our environment. She consistently makes the tools – software, wetware, hardware – needed to answer her research questions. Her collaborative works have been shown at the Venice Biennale (2016), the Storefront for Art and Architecture in New York, and the Detroit Science Gallery, among others. She currently holds an Assistant Professor position at the NYU Tandon School of Engineering in New York and teaches courses in biodesign.

- Eva L’Hoest
Born in 1991, Liège, Belgium. Lives in Brussels.
L'Hoest focuses primarily on the exploration of memory and its strange and minute lingering reality. She tracks the often blurred and non-specific ways in which reminiscence appears. Working on the outer edge of perception where it becomes affect and emotion; starting out with accidents of light like “the operator of a memory who interprets, distorts selects or sometimes saturates and alters the images”. Piece by piece, the artist appropriates contemporary technology to reveal both their nature as prosthesis for capturing the world and their potential as an artistic medium. Her work has appeared in the recent exhibits “Suspended time, Extended space” Casino Luxembourg, Luxembourg; “Fluo Noir” BIP2018, Liege, Belgium; “WHSS” Melange, Cologne; “Mémoires” ADGY Culture Development Co. LtD., Beijing, “Trouble Water” Szczecin Museum, Szczecin, Poland; “Snake Driver” Galerie Albert Baronian, Brussels; “Now Belgium Now” LLS358, Antwerp, Belgium; “Chimera: Marcel Berlanger, Djos Janssens and Eva L’Hoest” Meetfactory, Prague; and “Marres currents #3: Sighseeing” Maastricht, The Netherlands. In 2018, her films were on the calendars of the Rencontres Internationales Paris-Berlin, the Visite Film Festival, and Vidéographie 21. Screenings were held at Carreaux du Temple, Paris, Haus der Kulturen der Welt, Berlin, and Muhka, Antwerp, Belgium.

- Fernando Ortega
Born in 1971, Mexico City. Lives in Mexico City.
Ortega’s practice is largely concerned with poetic, serendipitous moments that arise from the processes of daily life, his pieces take on many forms. For Ortega, art making is an exploration of his own doubts and curiosities about the mysteries he encounters in the world. Through installation, performance, and sound, he modifies spaces, stages actions and works with materials as diverse as spider webs and construction cranes. In his projects, the idea of spectacle generally associated with galleries and museums is transported outside the exhibition space into a day-to-day realm, where the subtleties of the mundane and neglected take the center stage. Many of Ortega’s works balance gracefully between visibility and invisibility: they examine the relative scale and permanence of materials; and explore our human relationship to time and how it informs our experience of the world. His most important solo exhibitions include: “Nota Rosa”, Museo Tamayo, Mexico City (2016); “Fernando Ortega”, Palais de Tokyo, Paris (2012); “Levitación asistida”, Museo de Arte Carillo Gil, Mexico City (2008); “Winter Falls”, Bonner Kunstverein und Artothek, Bonn (2008); “Project Room”, ARCO 04, Madrid (2004); “Resumen”, Fundación Ludwig de Cuba, La Havana (1998). His work has also been a part of the following biennials: 14th Lyon Biennale (2017); 11th SP-Arte – São Paulo International Art Festival, Brazil (2015); 13. Istanbul Bienial (2013); 30a, 27a, and 25a Bienal de São Paulo (2012, 2006, and 2002, respectively); Biennial of the Americas, Denver, United States (2010); Biennale Cuvée 08, Linz, Austria (2008); 50th Venice Biennale (2003).

- Sean Raspet
Born in 1981, Washington D.C. Lives in Detroit.
Raspet’s works have often consisted of liquid chemical formulations of artificial flavour and fragrance molecules. More recently his works have involved food, nutrition, human metabolism and human cellular development via stem cells. He is a flavour and fragrance chemist and co-founder of the algae-based food company Nonfood. His practice prioritises movement away from the specialised art economy, in favour of endeavours that circulate in the economy-at-large, utilising prevailing modes of production – such as mass-produced products and proprietary molecular structures. Raspet’s work has been exhibited at Artist’s Institute, New York, Museum of Contemporary Art, Chicago; Museum of Contemporary Art, Detroit; de Young Museum, San Francisco; Jessica Silverman Gallery, San Francisco; M Woods Museum, Bejing; Societé, Berlin; the 9th Berlin Biennale; Bridget Donahue, New York; Sculpture Center, New York; and The Kitchen, New York, among others.

- Pamela Rosenkranz
Born in 1979, Switzerland. Lives in Zurich.
Rosenkranz’s work addresses the shifting philosophical and scientific meanings of the “natural” and the “human” during the time of the Anthropocene (the geological epoch marked by the impact of human activities on the ecosystem). Rosenkranz deploys a palette of patented icons like branded water bottles, JPEGs of International Klein Blue, and Amazon, the largest retailer to date in comparison to its inspiration, the Amazon as river and rainforest. By challenging the distinction between the natural and the artificial, Rosenkranz addresses the evolutionary and material dynamics underlying perception, art, and culture. Recent solo exhibitions include Foundazione Prada, Milan (2017), Venice Biennale (2015), Centre d’Art Contemporain, Geneva and Kunstverein Braunschweig, Braunshweig (2010), and more. Recent major group shows include Louisiana Museum of Modern Art, Copenhagen, Kunsthalle Mainz, Mainz (2017), Karma International , Zurich (2014), MoMA PS1, New York (2013), Berlin Biennale and Manifesta (2008).
