Willemsen presents two distinct art pieces inspired by her academic experiences, in virology, microscopy, and infectious disease modelling.

Virulent Scream is an expressionistic triptych that invites the audience to confront the vast realm of infectious diseases and virology. In the central panel, an agonized scream releases a virus from the mouth, while the side panels depict a withering funeral flower and decaying bird, symbolizing the universal impact of viral diseases on plants, animals and humans alike. Created sustainably with recycled print paper, charcoal and acrylics, this piece aims to unsettle the detached viewer and bridge the emotional gap between scientific facts and human experience.  

​

​Invisible  offers a layered and immersive depiction of viral infections, capturing their chaotic and cryptic nature. Created with salvaged materials—acrylics, markers, wall filler, and scrap paper on a torqued canvas—the artwork reflects the fragmented and often incomplete understanding of these microscopic phenomena. Its unsettling palette and cryptic annotations evoke the duality of fascination and frustration inherent in studying the invisible world of viruses.
