IMS Pacific-Rim Complex-Simplectic Geometry Conference in 2019 was held at the Institute of Mathematical Sciences (IMS) at ShanghaiTech University from July 28-August 3, 2019. The conference brought together active and leading researchers to exchange experience, knowledge and ideas about the most recent developments in various aspects of complex and Kähler geometry, algebraic geometry, symplectic geometry and Riemannian geometry. Over 40 researchers participated the 7-day conference and 23 plenary lectures were given covering some of the most exciting recent works in these fields.
