In my diptych paintings made with acrylic, wool, and graphite on canvas, I use abstract geometric forms that evoke the human head to present the sheer beauty of color and texture in a way that can be viscerally felt, as well as responded to psycho-physiologically by the eyes; and invite viewers to consider the process of visual perception:
If the viewer stares fixedly at the center of the painted panel on the left for about ten seconds, and then transfers gaze to the center of the drawn panel on the right, an after-image will appear in the complementary colors.

My graphite and black pastel drawings titled self-portrait and sequentially numbered, in which I explore the chromatic, light absorbing and reflecting qualities of both mediums, are more about the portrait of the self – that intangible essence of being, and the head as a container of memory, dreams, ideas, and aspirations. ”
