Assistant Professor - decoding the complexity of vascular physiology and blood flow control, one ion channel at a time. @Harraz_Lab @UVMvermont
Burlington, VT
Joined February 2011
Dr. Yaghi did his Nobel-winning work in the US, at the University of Michigan, UCLA, and UC Berkeley. Being welcoming to immigrants helps make American science the best in the world.
This year’s chemistry laureate Omar Yaghi was born in Amman, Jordan, in 1965 to parents who were refugees from Palestine. When we spoke to him he shared his story: “I grew up in a very humble home, we were a dozen of us in one room, sharing it with the cattle that we used to

Inspiring..
“My parents could barely read or write. It’s been quite a journey, science allows you to do it.” New laureate Omar Yaghi was in the middle of changing flights when we reached him, just after he heard that he had been awarded the 2025 #NobelPrize in Chemistry. In this interview

Why do we do what we do? The "My Why" campaign will help disseminate and strengthen this message. Let's tell our stories and share what keeps us busy with research!
Introducing the“My Why” campaign... We invite all Larner researchers to share the motivations driving their work so we can shine a light on the essential role of research and funding in advancing medicine. Share your 'why' at: https://t.co/RVeh87XQuW

It was fun! Thanks for the shoutout!
Now: @OsamaHarraz - graduate of our Center for- giving a Ted Talk at @UVMLarnerMed Research Rally! We need to look at the traffic in the brain, not just the structure! We need to learn how to give the brain lifelines back to restore orderly traffic! An exceptional communicator!

Extremely happy to see the first paper of the lab out in @NatureSMB. We determined the cryo-EM structures of GluA4 (alone) and in complex with TARP2, trapping the receptor in different functional states.

Very true!
New PI life: competing with the “big labs” for rotation students feels like bringing a salad to a pizza party. 🍕🥗 No takers this round, but we’ll keep cooking 💪— the right students will come🫵

New preprint from @mfco5m et al: Beat-locked ATP imaging in mouse SA node reveals an energetic hierarchy—high-Ca-ATP gain cells set rate; low Ca-ATP gain cells expand bandwidth & stabilize under load. Pacemaking is a beat-to-beat division of labor.

Pacemaker myocytes of the sinoatrial (SA) node initiate each heartbeat through coupled voltage and Ca2+ oscillators, but whether ATP supply is regulated on a beat-by-beat schedule in these cells has...
