Qui sóc?

Sóc Professor Agregat (Associate Lecturer) a la Facultat de Matemàtiques i Informàtica de la Universitat de Barcelona.
He impartit diversos cursos de mètodes numèrics, equacions diferencials, sistemes dinàmics, anàlisi matemàtica, estadística, programació científica,... a nivell de grau. També imparteixo classes d'algebra lineal numèrica en el master "Data Science" de la Facultat de Matemàtiques i Informàtica.

Estic interessat en el camp dels sistemes dinàmics en general i, en particular, en dinàmica Hamiltoniana, aplicacions simplèctiques, escissió de separatrius, teoria de bifurcacions, caoticitat, pertorbacions feblement dissipatives, dinàmica d'atractors estranys i mètodes numèrics adaptats a l'estudi de sistemes dinàmics.
