🌍 Gravity was here long before us—and it’ll be here long after we’re gone. Every part of our bodies evolved to manage this force.
💫 So excited to announce my new book, PULL, which uncovers the force that shapes your body, mind & health.

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 🌍 💪

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...

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?

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.

I’m currently developing a framework called "cognitive rewilding"—using spatial computing to counter pervasive biophobia and reconnect digitally detached minds with the natural world. It’s part of a broader idea I call "The Reality Paradox": using tech to return to what’s real. More soon! 🌱🧠🌍
