"My non-traditional path to art through a doctorate in neuroscience arms me with an outsider’s perspective and gives me the freedom to  introduce  imagery and concepts derived from a different world than is traditionally encountered in fine art. My work is neonaturalist, art based on natural forms and influenced by scientific advancements that allows us to perceive the universe beyond human senses. Neonaturalism harmonizes unfamiliar scientific imagery and techniques with an experimental artistic scaffolding. For example, it demonstrates that fractal forms of nature are consistent across scale; that neural landscapes of the brain fit seamlessly into the established realm of Asian aesthetics; that expanses of the microscopic world are fundamentally equivalent to landscapes of the macroscopic world.


"Neonaturalism fuses the worlds of concept and aesthetics, chaos and order, art and data. This approach visually, conceptually, and  technologically brings the scientific method into design and technique to produce pieces that demonstrate surprising and sometimes beautifully abstract notions about the unseen while commenting on the  common foundations of art and science in communicating human experience. Neonaturalism translates the perpetual stream of inspiration at the cutting edge of scientific research into visceral artistic form to  portray the immense beauty that pervades all corners and all scales of our universe."

Self Reflected, 2016, 22K gilded reflective microetching series

Depicting a sagittal slice of the human brain, Self Reflected is the most complex and detailed piece of art on human brain in the world, capturing the connection between the mysterious three pound macroscopic brain and the microscopic behavior of neurons. It offers an unprecedented insight of the brain into itself, revealing the enormous scope of beautiful and delicately balanced neural choreographies designed to reflect what is occurring in our own minds as we observe this work of art. Self Reflected was created to remind us that the most marvelous machine in the known universe is at the core of our being and is the root of our shared humanity.

  • Made of 25 etched plates and required two years to complete. 

  • Contains the circuit dynamics of around 500,000 neurons through a hyper-precise etching technique capable of yielding animations from reflected light, depicts 500 microseconds of “brain time.” 

  • Hand gilded with 1,750 sheets of 22K gold leaf.

  • The appearance of Self Reflected is wholly dependent on its lighting, meaning that it can be displayed in animation or colored light. 

  • Installed with a programmable light array with 144 independently controllable LED fixtures.

  • Is made with a combination of hand drawing, adapted neuro-scientific data, algorithmic simulation of neural circuitry, photolithography, strategic lighting design, and gilding.

About the Artist


Greg Dunn is an artist who received his PhD in neuroscience from the University of Pennsylvania in 2011. While a graduate student, Dunn’s artistic experiments demonstrated that the qualities of neural forms cleanly fit into the aesthetic principles of minimalist Asian art and sumi-e scroll and gold leaf painting. Dunn is now a full time artist based in Philadelphia where he works to incorporate his knowledge of neuroscience, physics, and biology into the artistic process through imagery, concept, and technique.


Together with Dr. Brian Edwards, a collaborating artist, applied physicist and electrical engineer at University of Pennsylvania, Greg invented a revolutionary technique called reflective microetching that allows dynamic control of imagery and color in reflective gold surfaces. This work has led to the awarding of a grant from the National Science Foundation to produce an enormous 8’ x 12’ microetching of the human brain, the most complex and detailed artistic depiction of the brain that will exist in the world. The piece is now permanently installed at the Franklin Institute in Philadelphia

Blaze in the Black, 2013,  21” X 29” or 24” X 32”, 22K gilded microetching. 

A reflective microetching that reveals the point in deep meditation where a very quiet mind begins to perceive a bright light. Conceptually, this light is only visible when the viewer is standing at the center of the etching wherein the etching is illuminated with shafts of light emanating from the light source above. Much like the meditator's mind, when agitated, can no longer perceive this light, when the viewer moves off of center the light is no longer visible.
