PRESENTATION
PRESENTATION
I am a math professor at UFRJ, Rio de Janeiro, since Jan 2025. Before that, I was at UFF, Niterói, since 2016.
I got my PhD at UBA, Buenos Aires, in 2010 and wrote my Thesis on Homotopy Theory and Category Theory under the advice of Gabriel Minian. I had postdoc experiences at IMPA, Rio de Janeiro, IST, Lisbon, and UU, Utrecht. I was also Visiting Professor at IMPA and at CRM, Barcelona. Here is a link to my full CNPq Lattes.
RESEARCH
RESEARCH
I am currently a CNPq Productivity Fellow (PQ1D: 2021-2025, PQ2: 2018-2021). I had a FAPERJ APQ1 Grant (2019-2021) and a FAPERJ JCNE Fellow 2021 to 2024 I was a JCNE Fellow.
My research areas are Algebraic Topology, Differential Geometry, Mathematical Physics, and Category Theory. I work with Lie Groupoids and Lie Algebroids, and their role in Poisson and Symplectic Geometry. A list of my papers and citations is available at my Google Scholar profile, and my preprints can be downloaded from arXiv.org.
TEACHING
TEACHING
Here are some drafts of concise lecture notes (in Portuguese) on Espaços Métricos and Álgebra Linear. They are works in progress, please feel free to use them, and let me know of any comments, corrections, or suggestions you may have.
The courses I have taught for graduate students are Topologia das Variedades, Geometria Simplética, Teoria de Lie, Grupóides e Algebróides de Lie, and Topologia Algébrica (PhD), and Álgebra Linear and Introdução à Topologia (Master).
ADVISING
ADVISING
I am currently advising Rafael Hernandez Bolaños (UFF, Master) and also co-advising Dario Aza (UBA, PhD) with Federico Quallbrunn.
I formerly advised Juan Desimoni (UFF, PhD, 2023), co-adivsed Daniel Lopez (IMPA, Master, 2017) and Mateus de Melo (IMPA, PhD, 2019), and Caio Magalhães (UFG, Master 2024). I also supervised Cristian Cárdenas (UFF, Postdoc, 2019) and Eduardo Velasco Barreras (UFF, Postdoc, 2020).
If you want to work with me, send me a message, we can discuss some problems, and I can help you apply for fellowships.
