Jane Goodall was my first example of how a childhood love for nature could evolve into a lifelong purpose.

I’m deeply honored to be named to this year’s #TIME100Next list. time.com/collections/...

While at a winestore in rural New York State this weekend, I happened to be wearing a t-shirt from my time in the U.S. Public Health Service. At checkout, one of the staff asked, “Does that even still exist?”

Jane Goodall has been my hero since childhood. In challenging times, I often turn to her for guidance—and that’s why I just read her "Book of Hope". It’s an incredible piece that reinforces for me that hope is not passive—it’s a discipline, a choice, and a call to action. 🧵

What’s happening at CDC should concern all of us. Public health threats don’t care about politics or borders.

🌍 Exciting News for Global Health Professionals! The Global Health Council (GHC) has launched an Individual Professional Membership—a fantastic opportunity to stay engaged in global health at a time when collaboration and informed advocacy are more critical than ever.

This has been the hardest week I’ve had in a long time. 🧵 (1/6)

I'm excited to be in the running to speak at #SXSW 2025 with @monicamedinadc.bsky.social on why human health depends on nature. If you could take a moment to vote in support of this proposal, I'd greatly appreciate it! Thank you! 🗳️ Vote by Aug 24: lnkd.in/em3MDMiC ❤️ Click the heart! #OneHealth

Just finished reading Biocentrism by Robert Lanza and Bob Berman. It’s one of those books that shakes up your assumptions about reality. 🧠🌌

Just finished "Everything is Tuberculosis" by John Green—and I can’t recommend it enough. As a TB doctor, I thought I understood this disease. But until I read this book, I hadn’t fully grasped just how deeply TB is woven into the fabric of our history, society, and even geography. 🧵

Over 100,000 people die from measles each year globally—a completely preventable tragedy. With U.S. cases rising, we risk losing our elimination status. I shared insights with @emilymullin.bsky.social / Wired magazine on what’s driving the outbreak. www.wired.com/story/can-us...

Honored to work alongside so many committed colleagues. We can reduce spillover risk — and in doing so, we: 🌍 Prevent pandemics 🌱 Fight climate change 🦋 Protect nature ⚖️ Advance equity The path forward is clearer than ever. Let’s act. #OneHealth #SpilloverPrevention #GlobalHealth #ClimateAction

A historic day! The Pandemic Agreement is adopted! 🌍✍️ This landmark achievement will make the world safer from future pandemic threats.

Check out my ode to reptiles in the LA Times. This Earth Day, may we all resolve to admire the exquisite variety of life on this planet; meet the strange and fearsome with curiosity; and remember that we are one small part of nature, rather than masters of it. www.latimes.com/opinion/stor...

Loss of nature is promoting the spread of infectious diseases. I joined @lisapatel.bsky.social's Healthy Climate America podcast to discuss this and so much more--including why we should retain hope during challenging times. Listen here: bit.ly/HealthyClimateAmerica

Thrilled about this news out of the @who.int. If adopted next month, the pandemic treaty will leave us all safer. @alexandrafinch.bsky.social , @nschwalbe.bsky.social and I shared a few thoughts on this with the NY Times. www.nytimes.com/2025/04/16/h...

One of my personal missions is to do what I can do bridge the divide in an increasingly polarized world—that’s why I wrote this essay for Men’s Health about jiu jitsu and what it can teach the US about community. I have hope during these difficult times. www.menshealth.com/fitness/a644...

Sharing our new @thelancet.bsky.social piece on spillover prevention & #OneHealth in the WHO #PandemicAgreement. We call on states to adopt the agreement next month. Huge thanks to @alexandrafinch.bsky.social for leading this. Let's get this done and make the world a safer place! bit.ly/3E7RKeu

To safeguard against a pandemic of #H5N1 avian flu, @conservationdoc.bsky.social says Health and Human Services Secretary Robert F. Kennedy, Jr should embrace his environmentalist roots—and capitalize on One Health practices to protect the public.

Thrilled that “One Health” is included in this @npr.org piece on global buzzwords for 2025. There is no human health, animal health, or environmental health—there’s just One Health. www.npr.org/sections/goa...

👇Must-read piece this weekend by @emmagoldberg.bsky.social @nytopinion.nytimes.com and as you and your orgs consider year-end giving priorities. As someone who has been on both the grantee and donor sides of the table, a few reflections: 🧵

Thrilled that 196 governments have agreed that biodiversity is a key determinant of health. This Plan is the closest global agreement that there is on planetary health. My colleagues and I discuss this in the @thelancet.bsky.social: www.thelancet.com/journals/lan...

So fun to record this podcast for @mongabay.bsky.social! @mikedigirolamo.bsky.social and I go into pandemic prevention, and then move into the importance of storytelling and why we need more collaboration between scientists, artists, and philosophers. Cheers! news.mongabay.com/podcast/2024...
