Dr. João de Deus Pereira de Moraes Segundo is a Mechanical Engineer (B.Sc. and Ph.D.) and researcher specializing in polymeric membranes, nanocomposite materials, and transport phenomena. With extensive doctoral and postdoctoral experience, his work bridges polymer processing, rheology, and continuum mechanics to engineer hierarchical porous structures via electrospinning and phase inversion (NIPS). His research interests encompass high-efficiency air and water filtration, antiviral/antimicrobial functional materials, green solvent systems, and the application of machine learning and polymer informatics to membrane design. Apaixonado about engineering education and open-source hardware, his mission is to translate sustainable, high-performance membrane technologies from bench-scale prototypes into practical industrial, environmental, and healthcare solutions.
