Gratitude to the University of Sao Paulo faculty.

Thank you for three decades of science and clinical care for people living with HIV in Brazil, and for bringing that same devotion to public health into the leadership of Latin America's largest research university.

Thank you for turning the genetics of muscular dystrophy into real hope for thousands of Brazilian families, and for building a human genome and stem cell research center where patients always come first.

Thank you for four decades of measuring the breath of the Amazon, aerosol by aerosol, and for carrying that evidence into the IPCC so the world could act on what the forest was telling us.

Thank you for sequencing the genome of the new coronavirus just 48 hours after Brazil's first confirmed case, and for a career spent making blood transfusions and public health safer for the whole country.

Thank you for telling Brazil the truth about its own history of race, slavery and empire, in books so alive that rigorous scholarship became something millions wanted to read.

Thank you for showing how sugarcane and the plants of Brazil respond to a changing climate, and for putting Brazilian plant science at the center of the global bioenergy conversation.

Thank you for proving, particle by particle, what polluted air does to human lungs, and for making the health of city dwellers a matter no government could comfortably ignore.

Thank you for building protein crystallography for drug discovery in Sao Carlos, and for leading Brazil's national research council with a scientist's honesty while opening structural biology to a generation of students.

Thank you for defending the rights of migrants and of patients during Brazil's pandemic with the full rigor of international law, and for training a generation to see global health as a matter of justice.

Thank you for a lifetime of showing that energy done wisely is development done right, from ethanol science to the global environmental agenda, and for still teaching Brazil candor at 98.

Thank you for a lifetime of reading Spinoza with Brazilian eyes, and for naming authoritarianism in everyday life so clearly that generations of students learned to think against it.

Thank you for teaching philosophy of law with the same hands that organized the 1992 Rio Earth Summit, and for showing that diplomacy and scholarship can honor each other.
