About me

I am Henrik Bradtmüller, an Assistant Professor of Physics at the São Carlos Institute of Physics, University of São Paulo (IFSC/USP), Brazil. I use solid-state NMR spectroscopy to study how the atomic structure of glasses and glass-ceramics influences their properties.

Research

My work connects glass composition with chemical durability, ion transport, and crystallization. I combine NMR experiments with complementary measurements and molecular dynamics simulations, with three main interests:

• Bioactive and niobium-containing glasses: how local atomic environments and network connectivity affect dissolution and other material properties.
• NMR methods: experiments that reveal the environments of quadrupolar nuclei and the proximity of different elements in disordered solids.
• Relaxation and crystallization: how atomic arrangements change as glasses relax and crystalline phases form.

These questions span silicate, phosphate, borophosphate, and borosilicate systems. At IFSC/USP, I work with Marcos de Oliveira Jr. and our students, with support from FAPESP’s Young Investigator program.

Background and teaching

I joined IFSC in April 2025, after postdoctoral research with Edgar D. Zanotto at UFSCar. I completed my doctorate in physical chemistry at the University of Münster with Hellmut Eckert and Michael Ryan Hansen.

Alongside undergraduate physics and laboratory teaching, I write practical NMR tutorials. These explain both the software steps and the reasoning behind processing and fitting decisions.
