Dr. Ontko’s research focuses on the anticancer activity of gold-containing coordination complexes in a variety of ovarian cancer cell lines. Specifically, his group examines the effects of a) the oxidation state of the central gold atom, b) variations in the ligand environment, and c) gold induced apoptosis on cellular signaling processes.  Other research interests include overcoming cancer resistance, DNA-based biosensors, and transition metal containing micronutrients.
