With deep sorrow, I received the news of Dr. Eugene Braunwald’s passing, one of the greatest figures in world cardiology.

His scientific legacy, clinical vision, and immeasurable contribution to generations of cardiologists will continue to live on in our daily practice and in the history of medicine.

My heartfelt condolences to his family, friends, students, and to the entire cardiology community. May he rest in peace.

The first time you start a research lab, there’s no manual.

So I made one.

A practical toolkit for postdocs and early-career faculty launching their first lab: hiring, startup planning, collaborations, and building a sustainable research program.
