Diego Chaves graduated in Chemistry from the Federal University of Viçosa, campus-Florestal (Brazil) in 2013. He completed his MSc and DSc degrees in Agrochemistry-Inorganic Chemistry at the Federal University, campus-Viçosa (Brazil) in 2016 and 2020, respectively. During his postgraduate studies, Diego worked for six years at the Homogeneous and Heterogeneous Catalysis Laboratory, where he learned methodologies to prepare and test Keggin-type heteropoly salts in the development of catalytic processes for biomass valorization. During this time, Diego also acquired expertise in advanced material analysis techniques (ATR-FTIR, TGA/DSC, XRD, XANES and EXAFS, SEM/EDS, BET analysis) as well as organic compound identification and isolation (NMR ¹H and ¹³C, GC-MS, GC-FID). After completing his DSc studies, Diego worked for one year as a Collaborative Researcher in Analytical Chemistry at MCDALab (Federal University of Viçosa). During this postdoctoral period, Diego focused on Nb-catalysts and lignocellulosic material pretreatment, supervised master's and undergraduate students, learned and applied design of experiments, and was responsible for HPLC analysis, method development, and training. In 2022, Diego was selected for a postdoctoral position at University of Minho, sharing his research time between the Centre of Biological Engineering and the Centre for Science and Textile Technology (2C2T). During his post-doc he began working on processing natural fibers to improve the circular economy in the Portuguese textile industry as part of the Be@t PRR project. Currently, Diego is a Research Assistant, working with the InnoFiber Research Group (2C2T), focusing on the processing of fibers for sustainable textile materials.
