239 steps up Duke Chapel with the QIAL team! Worth it for the view, the reset, and the reminder to step back and see the bigger picture.

Congratulations to Dr. Rohan Nadkarni on successfully defending his PhD today. We are proud of all his hard work and contributions in the QIAL lab, and we wish him the very best ahead.

Congratulations to QIAL’s Dr. Alexandra Badea and Dr. Trong-Kha Truong on receiving the 2025 Medical Physics Fall Seed Grant Award for their project, “Predictive Modeling of Alzheimer’s Disease Risk Using Explainable AI and High-Resolution MRI.”

Delighted to host Dr. Kristina Bliznakova, Fulbright Scholar, at Duke’s Quantitative Imaging & Analysis Lab. Looking forward to teaming up on photon-counting CT and virtual  imaging.

Our team developed anatomically variable digital Wistar rat phantoms for realistic preclinical imaging simulations, enabling PCCT studies & reducing animal use. Segars, H. E., Nadkarni, R., Badea, C. T., Badea, A., Chin, B., Johnson, G. A., Payne, J., Samei, E., … Continue reading →

Our QIAL lab member Rohan Nadkarni brought the heat at the BME retreat—taking 2nd place in the rapid-fire challenge with original rap lyrics

Congratulations! Dr. Hae Sol Moon has successfully defended his PhD on “Integrative Modeling of Alzheimer’s Disease Risk”.

Huge congratulations to Dr. Alex Allphin on a successful PhD defense! A key member of our QIAL lab, Alex’s work has pushed the boundaries of imaging science.

Voluntary & enforced exercise drive distinct brain changes in Alzheimer’s models.MRI reveals how emotion, memory, & motor circuits adapt—showing exercise’s neuroprotective power. Badea A, Mahzarnia A, Reddy D, et al. Neuroimaging biomarkers of neuroprotection: Impact of voluntary vs. enforced exercise … Continue reading →

This study investigates the impact of exercise on cardiac function across different APOE genotypes in mice using low-dose cardiac photon-counting micro-CT and deep learning-based segmentation. Results show significant, genotype-dependent improvements in cardiac performance, with the largest effects observed in APOE3 … Continue reading →
