Bridging materials science, technology, and sustainability

Advanced materials have an unparalleled ability to reshape medicine, energy, and electronics. Our group, Multifunctional Devices and Materials Development and Innovation Group (GDDM), designs multifunctional materials — from complex oxides to magnetic nanoparticles — and uses AI-driven discovery to turn scientific insight into real-world impact.

Multiferroics & Smart Devices

We employ a wide range of experimental techniques — including X-ray and neutron diffraction, electron microscopy, impedance spectroscopy, and magnetic and dielectric measurements — to investigate the electrical, magnetic, multiferroic, structural, and microstructural properties of materials and devices, establishing the structure–property relationships that guide the design of sensors, microelectronics, spintronics, and energy harvesters.

Nanomedicine Innovations

Imagine treating cancer with particles thousands of times smaller than a human hair — that is the promise of nanomedicine. We design biocompatible magnetic nanoparticles that can be guided directly to tumors, where they gently heat up and destroy cancer cells without harming healthy tissue (a technique called magnetic hyperthermia). These tiny particles can also carry and release medicines exactly where they are needed, and help doctors see diseases earlier through safer, non-invasive imaging methods.

Sustainable Energy Systems

We develop advanced materials that help generate and store clean energy and we use artificial intelligence to discover them much faster than traditional methods allow. One of our fronts is the production of special catalysts designed in the lab for green hydrogen generation. Beyond energy, we create materials that clean polluted water using magnetic particles togheter fungus that capture toxic metals from industrial waste — and can then be collected with a magnet. It is materials science working for a cleaner, more sustainable future.

About

Two decades advancing science without borders

Luiz Fernando Cotica
Prof. Luiz Fernando Cotica — Department of Physics, UEM

With a career spanning over two decades, I am a physicist dedicated to advancing materials science, fostering innovation, and addressing global challenges in healthcare and sustainability. My academic journey began at the Universidade Estadual de Maringá (UEM), where I earned my Bachelor's (1998), Master's (2001), and Ph.D. (2005) in Physics, followed by a postdoctoral fellowship at the University of Texas at San Antonio (2014).

I currently serve as Associate Professor in UEM's Department of Physics and as a Permanent Faculty Member of the Graduate Programs in Physics and Environmental Biotechnology. My leadership roles have included Vice-President for Research and Graduate Studies (2020–2022), Director of Research (2018–2020), and Coordinator of UEM's Innovation and Technology Hub. I also was the Coordinator of the Graduate Program in Physics at UEM (2022–2024), a prestigious Graduate Program with a CAPES score of 6, a national mark of academic excellence. Since 2025, I am the Head o the Department of Physics at UEM.

From 2016 to 2018, I directed UEM's Multiuser Central Laboratory (COMCAP), a facility with 120+ advanced instruments supporting over 3,000 researchers annually. As a coordinator of UEM's Internationalization Laboratory, I partnered with CAPES and the Fulbright Foundation to secure 36 international initiatives, expanding the university's global footprint.
