🚀 Today’s the day! My new book PULL is officially out in the world. Grateful for everyone who helped bring this project to life—and excited to share how gravity shapes our bodies, steadies our minds, and guides our health. Get your copy here: amazon.com/Pull-Gravity-S… 📖🌍

Thrilled to announce my new podcast, "The Gravity Doctors," together with @brennanspiegel.bsky.social. We introduce the world of "Biogravitational Medicine"—how gravity shapes your body and mind for better or worse. All formats here: lnkd.in/gyviV7HY YouTube: lnkd.in/gAMB_Eq8 Hope you enjoy!

IBD is more than inflammation. Patients can struggle with fatigue, pain, stress, anxiety & depression. In our new paper, we discuss how #VR might support the gut–brain axis, easing psychological comorbidities while complementing physical care. More: pubmed.ncbi.nlm.nih.gov/39990506/

Yes, I know this looks ridiculous 😅. But it works: weighted vest (20 lbs), ankle weights (20 lbs each), standing desk, balance board. My way of sneaking fitness into office hours—and resisting the sedentary pull of gravity 🌍 💪 Because...🧍‍♂️ > 🪑

Thrilled that my forthcoming book, PULL: How Gravity Shapes Your Body, Steadies the Mind, and Guides Our Health, has been named one of Next Big Idea Club’s Must-Read Books—curated by Malcolm Gladwell, Susan Cain, Adam Grant & Daniel Pink. So honored! nextbigideaclub.com/magazine/nex...

🌿 Green = Good 🌿 I’m standing in Geiranger, Norway 🇳🇴, surrounded by nature at its most spectacular 🌄. It reminds me of biophilia—our innate love of green, living spaces 🌱. Turns out, nature boosts serotonin 🧠 and lowers stress 😌. I can feel it.

Ever feel weighed down—literally or figuratively? What if serotonin is the secret to resisting gravity’s pull? Maybe this ancient molecule isn’t just about mood, but about helping us stand up to gravity—body and mind. I explore this idea in my new paper: neurogastrolatamreviews.com/frame_eng.ph...

Recording my new book PULL… from the only studio with optimal acoustics, shoe inspiration, and flannel ambiance: my closet. 🎙️👞👔 Grateful to the producers and directors at @StMartinsPress for making this audiobook come alive. Book info/pre-order: amazon.com/Pull-Gravity-S…

"IBS Rates Nearly Doubled During the Pandemic" - @healthday.bsky.social covers our new study examining time trends of #IBS following the COVID-19 pandemic:https://www.healthday.com/health-news/digestive-system/ibs-rates-nearly-doubled-during-the-pandemic

How should doctors use AI? What happens if insurance uses AI to deny claims? How should we consent patients when AI is used? How do we train med students in AI? Those are just a few of the questions I discuss this new @amcollegegastro.bsky.social "Brains and Guts" podcast: gi.org/journals-pub...

Just over 10 yrs ago, we showed how computers could write a more thorough patient history than doctors. Below is published example, from a decade ago, before LLMs. The tech has exploded since then. What happens now when we pair great tech w/ great docs? 🔗https://pubmed.ncbi.nlm.nih.gov/25461620/

Empathy erodes as digital distance grows. ⬆️ In-person: mirror neurons fire ▶️ Video/chat: filtered but still human ⬇️ Anonymous online: empathy floor Can we design tech that bends this line back up? 👇 #DigitalHealth #Empathy

Exciting day today at #CedarsSinai where we’re hosting “AI in Healthcare: Trust and Accountability,” a joint symposium with the Hastings Center. Program agenda shown. I’ll be joining a panel on ethical use of #AI and #digitalhealth in the community. It’s been very engaging so far!

Some days it feels like we’re living inside an intractable riddle. But there’s existential meaning in trying to solve it—even if we never plumb the depths.

Technology has extended our lives, cured disease, and connected the world—yet rates of anxiety, loneliness, and chronic disease keep rising. Have we passed the peak of benefit? If this curve is accurate, what’s our prescription for the descent? More tech? Different tech? Or just disconnect?

Doctors can't just "touch grass" during 14-hour shifts—but what if they could feel like they did? Today at #DDW2025 I’ll explore how #VR can help address burnout in medical training & beyond—offering biophilic escapes 🌿, real-time biofeedback 💓, and moments of calm in a high-stress world.

Powerful talk by Kayla Griffin at #DDW2025, sharing her journey as an artist living with #gastroparesis. Misdiagnosed with anorexia and anxiety, told she needed surgery—when it was gastroparesis all along. Her story and art reminded us why listening matters.
