Karthika Kelat is a third-year Ph.D. student in Biomedical Engineering, working in the Department of Radiology under the guidance of Dr. Claudia Mello-Thoms, PhD. Her academic journey includes holding a Master of Technology degree in Signal Processing and a Bachelor of Technology degree in Electronics and Communication Engineering. Karthika's research is focused on modeling radiologists’ visual search in breast cancer screening. With a profound interest in the intersection of machine learning and medical imaging, Karthika aims to advance the understanding of radiologists’ visual perception in 2D digital mammograms and 3D digital breast tomosynthesis. The focus of her research is to develop a model that can help radiologists reduce wrong decisions during breast cancer screening. Although she initially aspired to be a nurse, her current path allows her to impact patients' lives in a unique way. Beyond her academic pursuits, Karthika finds joy in traveling with her husband, Subin, who is also pursuing his Ph.D. at the University of Iowa.
