JULIÁN DAVID ARIAS-LONDOÑO
Doctoral student

Julián David Arias Londoño was born in Manizales, Colombia in 1983. He received his undergraduate degree in electronic engineering and his M.Eng. degree in industrial automation from Universidad Nacional de Colombia, Manizales, Colombia, in 2005 and 2007, respectively. Currently, he is pursuing a Ph.D at Universidad Politécnica de Madrid, Spain and Universidad Nacional de Colombia Sede Manizales. His main research is in the field of stochastic process and machine learning applied to biosignal processing.
