@BehnazGhoraani @Sensors_MDPI Congratulations🎉

Congratulations to my PhD students and our team on this ✨Editor’s Choice Article✨! Proud of their outstanding work on comprehensive gait analysis, recognized in @Sensors_MDPI

@shirin_sadri @S_NarayanMD @Sabya_Bando Congrats, Shirin! Great working with you!

#AHA25 was the best! Got to present our work in @S_NarayanMD lab with @ Kelly Brennan, @Sabya_Bando @prash030 using large language models to detect VT recurrence in clinical notes and enable prediction of outcomes, towards precision pharmacotherapy in VT.

@BehnazGhoraani Congrats!

Presenting our cutting-edge Parkinson’s research at #IEEEEMBC2025 in Copenhagen! Using wearables + AI to track and manage motor symptoms. Grateful to share this moment with my amazing PhD student Johnny Forde and colleagues!

Check out our state-of-the-art open weights MedGemma multimodal model for making sense of longitudinal EHR data as well as medical text and medical imaging data in various modalities (radiology, dermatology, pathology, ophthalmology, etc.) See the blog post linked below! ⬇️

Flow Matching (FM) is one of the hottest ideas in generative AI - and it’s everywhere at #ICML2025. But what is it? And why is it so elegant? 🤔 This thread is an animated, intuitive intro into (Variational) Flow Matching - no dense math required. Let's dive in! 🧵👇

Gemini powers our multimodal health research! 💙 In our new paper on multimodal AMIE, we're pushing conversational diagnostic AI beyond text to handle images such as skin photos, ECGs, and clinical docs, which provide crucial context in healthcare. Blog: goo.gle/42D0QcB Paper: gstatic.com/amie/multimoda… How do we make an AI reason like a clinician during a dynamic, multimodal conversation? One of our key contributions is multimodal state-aware reasoning, built on @GoogleDeepMind Gemini 2.0 Flash. Instead of just reacting turn-by-turn, AMIE maintains an internal "understanding" of the consultation: ✅ What is known about the patient? ✅ What are the likely diagnoses? ✅ What information (text or visual) is missing? This internal state allows AMIE to: 👉 Intelligently guide the conversation through phases like history-taking & diagnosis. 👉 Strategically ask for relevant images (like skin photos or screenshots of ECGs/docs) when its internal state shows uncertainty. 👉 Accurately interpret multimodal data and weave the findings back into the ongoing dialogue and diagnostic process. Essentially, it mimics the adaptive reasoning clinicians use, leading to a more structured and effective consultation. We evaluated multimodal AMIE against primary care physicians (PCPs) in a demanding, blinded OSCE study using 105 diverse multimodal scenarios. The results demonstrate clear progress: AMIE achieved similar or superior performance when compared to PCPs across a wide range of metrics, including diagnostic accuracy, empathy, and critically, the handling and reasoning about multimodal data. While the OSCE results are very promising, it's important to remember this was a test environment with patient actors! Real-world care is more complex. Making sure it's safe, reliable, and actually helpful in the real world needs more work, starting with our upcoming study with Harvard BIDMC. The work would not have been possible without an amazing team @GoogleAI, @GoogleDeepMind: @RyutaroTanno, @alan_karthi, @vivnat, @AdamRodmanMD, @timstro, @taotu831, @hardyshakerman, @JanFreyberg, @_cjpark, @yasharmaa, @apalepu13, @arkitus, @weballergy, @valentinlievin, @ckbjimmy, @davidstutz92, @dgtbarrett, @yongcheng16 @SaraM66905, @dr2w, @ymatias

Great reminders from @S_NarayanMD re: Mapping in the current era - we still have work to do! * EGMs ≠ Action Potentials * How to we compare across #AI models? Very tough to do * with implementation of AI, outcome & workflow need better synchronization #StanfordBiodesign2025

Why do we need #AI in #cardiacEP ? AI models can do tasks beyond humans' capability. Learning features unknown to humans, forecasting, automated remote monitoring, etc. Need more collaborative efforts to bring AI into practice. Great talk by @TinaBaykaner45! @SUBiodesign

Happening now: Stanford Biodesign New Arrhythmia Technologies Retreat at #SanDiego ! Opening remarks from @Wanginnovate @S_NarayanMD . Great talks coming up!
