Biomedical engineering master's students won the top honor at
@asmedotorg.bsky.social's Innovation Showcase for their invention, DINA—the Dynamic Infant Neurorehab Aid, a soft robotic suit created to help rehabilitate newborns with brachial plexus palsy (NBPP). engineering.jhu.edu/news/student...
Team members Victor Ticllacuri and Yuxuan Bai pose for a photo with Prof Nitish Thakor in front of their poster. Prof Thakor is holding a doll wearing the DINA. A lifelike doll wearing the DINA, a blue plastic brace-like device extending from the shoulder to the wrist.

Earth-bound telescopes can see much more of the sky than space telescopes, but the photos are blurry & noisy. Until now: @johnshopkinsams.bsky.social Assoc Prof Tamás Budavári's new algorithm removes atmospheric interference for clear views of faraway galaxies. engineering.jhu.edu/news/sharper...
Set of Hyper Suprime-Cam i-band exposures showing different levels of atmospheric blur and noise across multiple astronomical images. The bottom-right panels display the corresponding point-spread functions used for image restoration, while gray bands indicate chip gaps where data are missing. Side by side photo comparison of galaxies taken without (blurry) and with (sharper) processing from the ImageMM algorithm

Dramatically cutting the cost of fine-tuning AI: By recycling open-source low-rank adapters (LoRAs), PhD candidate Prakhar Kaushik and team are saving compute and energy with EigenLoRAx (named for the eco-minded Seuss character). Read more: engineering.jhu.edu/news/in-the-...
Technical diagram illustrating the EigenLoRAx methodology. Shows the flow from pretrained weights through LoRA adapters (labeled A and B) to multiple tasks, then extraction of principal components to create a unified EigenLoRAx system that generates task-specific coefficients for new tasks. Includes frozen and trainable components marked with snowflake and teddy bear icons respectively. Comparison of LoRA (top) vs EigenLoRAx (bottom) generated anime-style characters, demonstrating maintained visual quality with significantly fewer parameters across different character designs and artistic styles Comparison of LoRA vs EigenLoRAx in text-to-image generation. Top row shows images generated by individual LoRAs, bottom row shows equivalent quality images generated by a single EigenLoRAx with 18× memory reduction. Includes diverse styles: surreal forest scene, cyberpunk cityscape, 3D character portrait, and abstract street art.

Live from #CVPR2025! @jhu-bdps.bsky.social's Alan Yuille sharing his computer vision research at Hopkins Engineering's booth 1317. Stop by to learn how we're harnessing the power and promise of AI, data science and machine learning. Check out our faculty in attendance:
A large group in a convention booth watching as a professor describes his work, gesturing towards slides on a screen. Promotional flyer for “Data Science and Artificial Intelligence at Hopkins – Meet the Experts” event, listing speakers, their photos, affiliations, session times, and research areas. Featured experts include Tinoosh Mohsenin (edge AI, robotics), Rama Chellappa (AI, computer vision), Alan Yuille (AI, cognitive science), Vishal Patel (deep learning, biometrics), Reno Kriz (natural language generation), and Tianmin Shu (embodied AI). Hosted by Johns Hopkins University.

🪫🔋🔬 Research assistant (and new matsci grad!) Liam McMullin is tackling mechanical failure in next-gen solid state batteries. By redesigning the cathode, he’s helping pave the way for phones that last longer and EVs that charge faster. Read more: engineering.jhu.edu/news/long-la...
Liam McMullin operates equipment inside a glovebox, used to safely handle materials for solid-state lithium battery research. Liam McMullin conducts a lab experiment wearing safety glasses and gloves, part of his work optimizing cathode materials. Gloved hand inserts a sample into a device emitting a blue light, likely for particle size or stress testing in cathode materials. Liam McMullin holds a battery cell prototype developed to test composite cathodes with varied material ratios.
