Joao is a physicist, researcher, and professor in Brazil. He earned his Ph.D. in Physics at the University of Rochester, NY in 2013. He has written several papers in international journals, mainly in field theory and cosmology. Joao is also a researcher and the outreach leader for the BINGO telescope. This state-of-the-art radio telescope will be operating in the Northeast of Brazil in a few years. He believes in the importance of spreading knowledge and high-quality information among society and the public in general. He also believes that people can enjoy the learning process if it is funny and if they can see it as a path to change their life, even in daily activities. In his free time, he enjoys running, playing tennis, cooking, traveling, and having pleasant moments with his relatives and friends.

Professional background and credentials
João has been working with physics since 2003. He has always been interested in studying the Cosmos and loves observing the night sky. Along with his undergraduate studies, João has studied the interface between classical and quantum theory and how some symmetry properties can be responsible for a system having real quantum energy levels. During his master's, he worked with classical chaos theory applied to field theory, trying to map different types of solutions of field equations using a method called Poincaré sections. In his PhD, João developed a new method to find analytic classical field models. He also worked with quantum field theory on flat and curved spacetimes, with field theory at finite temperatures, and with gravitational models. Since 2014, he has worked as a professor of physics and researcher in Brazil. He is also a member of an international collaboration to construct and operate the BINGO telescope, the largest radio telescope ever built in Brazil. At Omni, he aims to make calculators and scientific subjects accessible to the general public. He also aims to contribute to developing new tools with his background and expertise. João believes people need to see science as part of their daily activities.
Achievements
João is a research fellow of the National Council for Scientific and Technological Development (CNPq, Brazil). He has also been a referee for thirteen international journals and has received several scholarships during his academic career. In the last few years, he has started working with scientific outreach activities, presenting astronomy, physics, cosmology, and science subjects in schools, scientific fairs, and congresses. He has also organized fifteen scientific events so far and is a member of the Brazilian Society of Physics.
