Tell me about you...

I am a full time Professor at Methodist Tech University Izabela Hendrix and PhD in Economic Sociology at Minas Gerais Federal University. I love programming (specially R, Python and C++), and I love working with Machine Learning and Network Analysis. Have been working as a consultant on Data Science, Analytics, Network Analysis and Web Crawling for a while. Open Source enthusiast!

What about your academic work?

sample-image My scientific investigations include the fields of Economic Sociology, Sociology of Art, Sociology of Music and Sociology of Education. I am interested on music and art markets, scientific productivity and scientific collaboration networks, international transaction networks, migration networks and inequality in educational system. I work mainly with Social Network Analysis, the base paradigm on which I am developing my dissertation.

I also teach disciplines in four undergraduate courses in Brazil: Data Science, Computer Engineering, Bioinformatics and Music. What I most like to tell my students is
