Bergman's work explores extinction, intimacy, unconventional love, and the future of the human body through sculptural installations. He investigates themes of inherited pain, historical narratives, and the language of materials, guided by a long-standing search for a visual expression of mortality tied to marginalization—something deeply personal and shared within his community.

Central to his practice is the tension between annihilation and tenderness, where queer intimacy—fragile and transformative—confronts identity and an innate sense of extinction. This inquiry extends to broader existential threats like the sixth mass extinction, drawing parallels between inherited trauma, bodily disintegration, and ecological collapse.

Bergman's sculptures often feature male-coded figurative forms and skeletal elements, created using a wax casting method he has developed, inspired by bronze casting. Layering pigmented wax with a brush, he merges painterly sensitivity with sculptural form. The resulting translucent, delicate works evoke a sense of bodily fragility and vulnerability.
