Leonardo Sacht

Thanks for visiting my website. I am a Mathematics Professor at UFSC, Universidade Federal de Santa Catarina, Brazil.

My research focuses mainly on Image and Geometry Processing. I am currently looking for motivated students at all levels (undergraduate, Master or Doctoral) that wish to work on the intersection of Mathematics, Computer Science, Engineerings and Applied Sciences.

Feel free to contact me: leo@mtm.ufsc.br
