I investigate time in drawing and painting. To create a visible record of time, I alternate and partially superimpose painted and penciled marks, experimenting with simple principles including younger-over-older and younger-cuts-older. Visible traces of earlier time intervals may be obscured by events occurring in later time intervals. Works exist on a continuum between mystery and enlightenment: only physical evidence of time may be provided, requiring deductive reasoning to unravel a history of events; or the title may reveal the order in which letters were created; or creation history may be shown plainly via numbering of pencil lines by time interval. Concerns include the desire to investigate and understand, memories of my late father, and the experience of living with and caring for my mother, who suffers from dementia.
