Proud parent moment! 🚀
My daughter’s AstroTech team at the Cornell Mars Rover is building the rover’s spectroscopy system for the University Rover Challenge.
They’re fundraising for components & travel—if you can please support our future engineers!

We developed a self-supervised #deeplearning method using sparse coding and #VisionTransformers to denoise pediatric cardiac #photoncountingCT. The model adapts to local noise and preserves anatomy. Clark, Cao & Badea, Med Phys (2025)

Thrilled to share that Hae Sol Moon has successfully defended his PhD! His resilience, creativity, and growth as a scientist carried him through every challenge. Great committee guidance and mentorship along the journey!
Proud and excited for what’s next! #PhDDefense #Duke #BME

[Cristian Badea @ct_badea]

Congratulations to my mentee Dr. Alex Allphin on the successful defense of his PhD in Biomedical Engineering! A major milestone achieved—wishing you all the best ! Well done! #photoncountingCT #DukeBME #QIAL

[Cristian Badea @ct_badea]

Our #QIAL latest study combines #photoncountingCT and #deeplearning to uncover how exercise improves cardiac function in #APOE mouse models. Major gains seen in APOE3 & APOE4—genotype-specific insights that could inform precision interventions🧠🫀🧬📄 https://t.co/4lmqsIwAGd

[Alexandra Badea @portokalh]

APOE is known for its role in Alzheimer’s disease—but it also shapes your bones.
Our study shows how APOE, immunity, and sex interact to alter bone structure in aged mice.
Grateful to Rohan Nadkarni & QIAL team for uncovering this brain–bone connection.

It was a pleasure presenting on Friday at the University of Toledo’s Bioengineering Department seminar, "Spectral Micro-CT Imaging: New Frontiers in Preclinical Biomedical Research." A big thank you to Prof. Juan-yu Lu for the kind invitation! #photoncountingCT #MicroCT

[Alexandra Badea @portokalh]

Excited to share our latest paper in Brain Structure and Function! 🧠✨

We explore how age & APOE risk factors impact long-range brain connections using multiscale bundle analysis.

A great presentation today by Rohan Nadkarni, our #Duke #QIAL group member on #PhotonCountingCT for bone imaging in APOE mouse models—showcasing how advanced imaging provides deeper understanding of bone and its connection to genotypes, sex, and immune system.

[Cristian Badea @ct_badea]

Great research presented at #SPIEMedicalImaging from our #Duke #QIAL lab! Dr. Darin Clark & Rohan Nadkarni showcase their latest work on #photoncountingCT #Deeplearning #MedicalImaging

Excited about the 2025 DIPY Workshop! Whether new to diffusion imaging or looking to deepen your expertise, this workshop offers something for everyone. Join us, learn with us, and help define the steps the field needs to take to advance. Thanks to DIPY team at IU and beyond!

[Alexandra Badea @portokalh]

Celebrating 40 years of dedication from Gary Cofer, the heart that has kept MRI pulses in required harmony, building hot diffusion application, and keeping things cool at the same time! Thank you!

[Alexandra Badea @portokalh]

How do risk factors for late-onset Alzheimer's disease impact brain networks? Read our latest publication to learn what diffusion imaging reveals about these key edges in the brain connectome, and how immunity interacts with APOE genotypes.
