• B.S. in chemistry, The Pennsylvania State University, USA

Research Interests

Dr. Lumsargis-Roth completed her Ph.D. at Purdue University where she worked in an ultrafast spectroscopy laboratory. During her graduate studies, she characterized and investigated charge dynamics at organic-inorganic 2D interfaces and perovskite quantum dots. She is now applying her knowledge of spectroscopy (PL, Transient Absorption, UV-Vis, FT-IR, & Raman) and microscopy to study the progression of ultramarine sickness in oil paintings. Ultramarine blue is a historical pigment which was used by artists around the world. Art conservation scientists and cultural heritage researchers have noticed that many oil paintings containing the ultramarine blue pigment have dulled over time. This fading is called ultramarine sickness. Dr. Lumsargis-Roth and her team are investigating the degradation mechanism of this effect through controlled UV-radiation on natural and synthetic ultramarine pigments dispersed in traditional, oil-based binding media. Frequent instrumentation utilized in her research include the Bruker Alpha FTIR, Varian 450-GC with 240-MS, Bruker NMR 400 MHz Ultrashield Plus, Shimadzu UV 2600i, and JEOL 6460LV STM
