Asad Ullah

Bio

I am a postdoctoral researcher at the Shanghai Institute for Mathematics and Interdisciplinary Sciences (SIMIS). I completed my PhD at the Universidade da Beira Interior, Portugal, under the supervision of Professor Helder Vilarinho. Before that, I completed a Postgraduate Diploma in Mathematics at the International Centre for Theoretical Physics (ICTP), Italy. I obtained my M.Phil (Master ’s) degree from Quaid-i-Azam University, Islamabad, Pakistan. My research is in dynamical systems, particularly in ergodic theory. I am interested in the existence of physical measures for certain dynamical systems using inducing schemes and in studying their statistical properties. I am also interested in continuity of physical measures.
