Shiva Abbaszadeh, PhD, is an Assistant Professor in the Department of Nuclear, Plasma, and Radiological Engineering at the University of Illinois. Her research seeks to develop state-of-the-art technology to visualize and detect cancer at the molecular level and to further our understanding of disease mechanisms. This research involves radiation detection and instrumentation for molecular imaging, computational problem solving, and quantitative characterization of biological processes. She previously developed a novel high-gain, high-resolution X-ray imaging detector that is currently being pursued for commercial use in low-dose mammography where maintaining excellent image quality at high spatial resolution is crucial. The proposed technology, based on direct conversion amorphous selenium, enables better detection of small tumors and facilitates early cancer diagnosis.
