Karla Kariny Ferreira Barbosa
PhD
Bachelor’s degree in Physics from the Federal University of Amazonas (UFAM, 2013), and M.Sc. (2019) and Ph.D. (2025) in Physics from the Federal University of ABC (UFABC). She has experience in the synthesis of REMEIKA-type intermetallic compounds via Sn self-flux and in the mechanochemical synthesis of lead-free double perovskites. Her expertise includes structural and optical characterization techniques such as UV-Vis spectroscopy, photoluminescence, SEM-EDS, powder X-ray diffraction (XRD), high-resolution transmission electron microscopy (HRTEM), electron paramagnetic resonance (EPR), SQUID-VSM magnetometry, and PPMS. Currently, she is a postdoctoral researcher at UFABC, focusing on the structural characterization of graphene-based materials for applications in nanoecotoxicology. She also works as a high school Physics teacher (Colégio da Polícia Militar and ETEC Carlos de Campos) and as a facilitator at UNIVESP, where she has supervised several integrative projects.
Jose Zuñiga
PhD Student
I graduated in Metallurgical Engineering from the National University of Engineering (UNI) in Lima, Peru, where I developed in the study and processing of polymetallic minerals and graphite, as well as working in engineering for the design of metallurgical plants. I completed my MSc in Materials Science and Engineering at the Federal University of ABC (UFABC) in São Paulo, Brazil. Focusing my research on thin films synthesis and transducers fabrication for electrochemical biosensors, using metal films, amino acids, enzymes and reduced graphene oxide (RGO) as a platform for biological events. Currently, I'm a PhD student in Biosciences at UFABC, continuing the development of transducers, but focusing on the piezoelectric properties of a polymer-ceramic composite material (RGO/GO) transducer to obtain an ultrasound biosensor, as well as continuing to work on the design of electrochemical biosensors.
