Post Grounds – A collaboration by students of the Academy of Media Arts Cologne (KHM) in the Art Collections of Ruhr University Bochum together with its Art History Institute.
Once traversed, it unfolds like a maze – a city within a city. It‘s a modern place of post-war architecture that, at its center, between concrete and art-in-architecture, houses the Art Collections of Ruhr University Bochum.

In the exhibition Post Grounds, students of the KHM enter into a dialogue with many of the works from these collections. Coming from the urban stage seminar, led by Prof. Mischa Kuball (Public Art), they bring their own artistic positions to the collections of the RUB, entering into a dialogue with its exhibits. The participants view the collections as a living, breathing space where past and future come together.

The exhibit grants insights to places that are easily overlooked and with performances, works in public spaces and interventions within the collections, tries to relate them to the rest of the campus. Thematically, the works range from thoughts on the physicality of bodies, to architectural violence and to questions of remembering. The Art Collections, places of art historical theory and museological praxis, are dynamically enhanced by the multifaceted views of the students.

Post Grounds – Eine Kooperation von Studierenden der Kunsthochschule für Medien Köln (KHM) in den Kunstsammlungender Ruhr-Universität Bochum mit ihrem Kunstgeschichtlichen Institut.

Betritt man den Campus der Ruhr-Universität Bochum wirkt er wie ein Labyrinth, eine Stadt in der Stadt, ein Ort moderner Nachkriegsarchitektur, in dessen Zentrum sich – zwischen Beton und Kunst am Bau – die Kunstsammlungen der Ruhr-Universität Bochum befinden.

In der Ausstellung Post Grounds bringen Studierende des Seminars urban stage unter der Leitung von Mischa Kuball (Public Art) ihre eigenen künstlerischen Positionen ins Campusmuseum ein und treten mit Exponaten der Kunstsammlungen in einen Dialog. Die Beteiligten verstehen die Sammlung als einen lebendigen Ort, an dem Vergangenheit und Zukunft aufeinandertreffen.

Die Ausstellung öffnet Blicke in Räume, die sonst leicht übersehen werden und tritt mit Performances, Arbeiten im öffentlichen Raum und Interventionen in den Sammlungen in Bezug zum Campus. Thematisch changieren die Arbeiten von Beschäftigung mit 
Körperlichkeit über architektonische Gewalt bis hin zu Fragen des Erinnerns. Die Kunstsammlungen, Ort der kunsthistorischen Lehre und musealen Praxis, werden in ihrer Funktion dynamisch um die vielfältigen Blickwinkel der Studierenden erweitert.
 
Dialogische Wege durch Post Grounds
Wie entsteht Kunst im Spannungsfeld von Architektur, Körper und Erinnerung?
Bei der dialogischen Führung durch die Ausstellung Post Grounds kommen Studierende der Kunsthochschule für Medien Köln (KHM) und des Kunstgeschichtlichen Instituts der RUB miteinander – und mit euch – ins Gespräch.

Gemeinsam führen sie durch die Ausstellung und eröffnen Einblicke in künstlerische Arbeitsprozesse, Sammlungsinterventionen und kuratorische Entscheidungen.
Ein Rundgang von Studierenden für Studierende – offen, diskursiv und auf Augenhöhe.

Voids


Juyoung Lee 
Photobook
14,8 x 21 cm

2026




















This work focuses on the accidental black voids found in user-uploaded Street View images,

moments where digital data fails and leaves a blank space. The artist views these glitches not as mere errors, but as openings for lost memories and new narratives. To fill these gaps, the artist wrote a short story for each void, then transformed their flat, digital shapes into physical form.

The sculptures are created in various sizes and textures to reflect each story and its context. When these pieces are placed in front of the ancient Odysseus sculpture at Sperlonga, they create a bridge between the past and the present. Just as the ancient marble statues were rebuilt from broken fragments, these modern sculptures represent an attempt to reconstruct what is missing in our memory and our digital world.

Together, they reveal a shared process: from broken traces to possible worlds, rebuilt through imagination across both antiquity and the digital age.

Japanese Blue


Yuanjin Wu
Photography, Video
82 x 58 cm 
39 x 25 cm

2025






















While living in Japan, I often encountered sudden train delays, later understanding that many were caused by suicide on railway tracks. A 2013 scientific study suggested that blue lighting at train stations could help prevent suicide, leading to its widespread installation across Tokyo platforms. Inspired by this context and Haruki Murakamis idea that death is an integral part of life, Japanese Blue imagines death as an inverted world. Through digital processing, I transform photographs of blue station lights into negative images, producing colors that appear both vivid and familiar. The work invites viewers to reflect on altered perceptions of life, death, and reality.

Intimität und Memoria


Sebastian Wilsch
Fotografie, UV druck, Wabenkarton
90 x 140 cm 

2025






















The work explores the relationship between memory and distance shaped by time and space. It focuses on how personal interactions, especially shared intimacy or brief encounters, is remembered, altered, or broken into fragments over time.Through visually distorted portraits that become recognizable only from a certain distance or when viewed through the lens of an mobile device, the work reflects on the fragile and changeable nature of memory. The grid is not only a visual element, but also a conceptual reference to the way memories are formed and reshaped - subjective, incomplete, and constantly evolving.



BIO


Sebastian Wilsch (*2000, Bonn) centers his artistic practice primarily on documentary
photography. His work navigates between everyday subjects and conceptually informed
approaches, operating within a space of tension between intimacy and societal reflection.
Wilsch explores central themes such as interpersonal relationships, identity, and
transgenerational debt through both photographic series and filmic works.

CUT

Shinyoung Rhyu 
Digital prints scanned from film 
developed with kelp
Subject : 152 x 228 mm
Object : 30 x 40 mm 

2025























Picking at my skin is an old habit of mine. It began when I was very young, before I was
even aware that it was a habit.

Whenever I concentrate on something, when I feel unstable, when I sit and read a book—
always, I pick at my skin. Wherever I’ve been, small pieces of my skin are left behind.
They range from tiny grains to slightly larger fragments. I leave parts of myself in the
places where I stay.

The spots where the skin has been torn away sometimes reveal soft pink flesh,
sometimes begin to bleed, and sometimes leave behind a dangling piece that hasn’t fully
come off. My hands are like my shame. When I show my hands to someone, I often try to
hide them.

No matter how much I pick, new skin always grows back. At night my fingers may be
torn up, but by the next morning I wake to find them ever so slightly smoothed over. I take
myself apart, I create my own shame, and my body heals itself.
I tried not to destroy anything, yet I destroy myself. Someone once called this habit a form
of self-harm. Above all, more than anyone else, I am the one who harms myself.
What are you destroying? The tattered corner of a book, hands dried from washing too
often, a window frame rusted from being left alone too long, bleeding lips, the long
horizontal scars on your back from growing pains.
I float our violences on water, in the most non-violent way.

SPECTRE HIDE

Niels Gössel
Installation of sculptures, polyurethane taxidermy base, plastisol, heat resistant glitter, fishing hooks and other paraphernalia, square tubing, fishing line
150 x 100 x 40 cm 
80 x 50 x 40 cm

2026























On a taxidermy foam base of a deer, replica antlers made with the materials and techniques of commercial fishing bait are mounted. They are cast from the hunting trophy of the deer that the artist‘s grandfather shot and killed. He was a serial pedophile rapist.

Fishing line hooks into them and spreads in a web of associations. 

Within a metal frame, interlocking patches of the same soft plastic are stretched like an animal hide being processed into leather. They are sewn together and show indentations reminiscent of those in surgical training kits.

The very specific shape of the patches is drawn from the mathematical disciple of tessellation: The spectre is a unique tile discovered in 2023 that can tile the plane only with itself (monotile) without ever creating a recognizable pattern (aperiodically). It repeats, but never in the same way.

The “hide” has been featured as costumes in the performance film TRAUMATOPHILIA (wt). 

The film imagines the workings of the cycle of transgenerational trauma, as each chapter uses a different mathematical shape to symbolize its conceptualization and rationalization, desperately trying to find a system of logic that can help make sense of what is ineffable.

Looking towards the laws of science in an attempt to resolve emotional turmoil, the installation is placed next to Richard Serra’s Right Angle Prop, exuding the legitimacy of the elementary principles of physics. The “hide”, too, is precariously under tension, the fishing line slowly cutting through the gelatinous plastic from all sides.



BIO


Niels Gössel (*1997, Münster) is a wood carver by trade and combines sculpture, film and performance in order to question (western) mechanisms of rationalization concerning trauma and social injustice. Each project seeps into the next in a continuous web of visual and conceptual associations, with queerness and psychoanalytic thought threading throughout. He lives and works in Cologne.

Choose your own conqueror (CYOC)


Alexandra Lex Nikitina
porcelain, LED light
four pieces 25 x 30 x 8 cm
four pieces 8 x 6 x 10 cm

2026






















CYOC (Choose your own Conqueror) is an installation based on a death mask of Napoleon Bonaparte, rendered in translucent porcelain. The masks are set in a row like soldiers awaiting orders, contrasting the serene facial expression of a dead man hovering from the wall at the height he used to stand at when he was alive - 168 cm. At the appropriate height below each face, a bare flaccid penis of the same material. Through the figure of Napoleon Bonaparte, the artist examines contemporary global political powers and societal turbulences. This current cultural climate, along with its informational mystification and personality cults, in many ways resembles the informational warfare Napoleon used. He retains his personality cult post mortem. His corpse is taken apart for souvenirs. His penis, hands and feet were cut off by an attending physician. At the moment, his penis is in the possession of an American heiress. The disinformation, started by Napoleon himself, lives on. Is it his death mask, or was the fake returned after it was stolen? Was his penis cut off, or was it replaced with the penis of a servant? 

Who ordered the physician to cut the body parts of Napoleon, and why? The blurred borders between superstition,religion and politics lead to a complete mythologization of the figure of the erstwhile tyrant of Europe - a meme, a cake, a psychiatric condition, a clown, a saint, whose dead body can be used as a personal keychain. For good luck.

Both drawings continue an ongoing exploration of familial bonds internalised within oneself and often perceived as unbreakable. The visual constellation in the larger drawing reflects how such bonds may fracture or be cast off, and what remains in their aftermath, including emotional and psychological residues.

Latent Core Dysfunction

Juri Lechthoff 
live video webcam feedback, LCD screens, RaspberryPi, Pure Data
222 x 50 x 40 cm

2026
























The work represents an approach to Adolf Luther’s concave mirrors. Latent Core Dysfunction draws on the optical distortions of light and mirrors that challenge our perception in Luther’s work and translates them into a hybrid space. Here, an overlap emerges between the digital and the material sphere. The installation involves us in its generative process, effectively using us as material. We are not the only ones observing—something gazes back from the in-between.

I aim to confront Luther’s work with modern technology and its impact on our perception of space and time. In doing so, I further explore the disrupted connection between self-experience and the external world. Moreover, I address surveillance and data processing as central themes of this work.

Post Right Angle I-III

17171717171717
CNC-milled wood, heat-treated steel, UV 3D print
120 x 100 cm

2026
























The triptych “Post Right Angle I–III” explores the transformation of constructive forms through generative design. While industrial design was long characterized by right-angled, standardized structures, AI-based optimization processes now lead to organic, material-efficient forms reminiscent of
natural load-bearing principles.

The CNC-milled wooden frames appear like fragments of a bone-like scaffold. Their organic form is broken up by polygonal surfaces that reveal their digital origins. At the center of each frame is a heat-treated steel plate with color gradients from blue to red, inspired by visual codes from stress and simulation software.

On top of this, 3D-printed scans of tree bark and spinal structures can be seen. These natural cell and support structures resemble the forms of generative algorithms. The work shows how digital technologies are once again taking up principles of nature and replacing rectangular industrial thinking.

Grievance Studies 

Gabriel Hahner 
Installation with Schimmelbusch anesthesia masks 
(on loan from the Medical History Collection at Ruhr University Bochum), printed fabric, figurines made from iron, paper mache, acrylic paint

2026























Pain is a physical reaction that is charged with cultural context. Reliable anesthesia masks
were not developed until the end of the 19th century, such as the Schimmelbusch mask, a
hinged mask into which a freshly sterilized piece of cloth soaked in chloroform is inserted.
Here they are combined with two Catholic saints who represent both pain and queerness: St.
Sebastian, patron saint of gay men and BDSM practitioners, and St. Agatha, who had her
breasts cut off and is important to some trans masc people.



BIO


Gabriel Hahner (*1997, Fulda) studied in the class for Performance Art at Kunstakademie Münster. They work primarily with sculptures and (video) installations. They explore the boundaries of bodies and eras, with a particular interest in intimacy and nostalgia.

RITUAL FORM 012

Alexandra Sakir 
Ink on Paper
460 × 148 cm

2026























The work is a large-scale ink drawing on paper created as a direct fixation of a bodily state. The process is not pre-planned; the form emerges through physical presence — standing, holding, breathing, and bodily weight. The gesture appears not as expression, but as a trace of being in space.

Paper functions as a vulnerable surface, receptive to pressure and impulse. Black ink condenses the moment, fixing the tension between body and environment. The line carries no symbolic meaning and refers to no narrative — it holds a state. The practice is grounded in an ontology of presence: the work neither represents nor comments on reality, but asserts the fact of bodily existence in space. Control and release coexist as a single process. The drawing becomes a trace of an inner axis maintained under conditions of pressure and uncertainty.



BIO



Alexandra Sakir (*1989, Russia) is a multidisciplinary artist working with drawing, performance, and media. Her practice is based on large-scale ink works as traces of bodily states. She explores presence as an ontological fact of the body in space, focusing on tension between control and release, endurance, and inner alignment.
