Research and career

Pham Hoang Hiep graduated from Hanoi National University of Education in 2004 and obtained his PhD at Umea University in 2008. He obtained a doctorate in science at Aix-Marseille University in 2013.^[7] He is known for being the youngest full professor in Vietnam.^[3][8] He is on the editorial board of Acta Mathematica Vietnamica^[9]

Pham has worked on plurisubharmonic functions and (with Jean-Pierre Demailly) found a lower-bound on the log canonical threshold of such a function. If ${\displaystyle \phi }$ is such a function then Pham and Demailly found a sharp inequality on the largest constant, c, so that ${\displaystyle e^{-2c\phi }}$ is integrable in the neighbourhood of a singularity.^[10][11] Pham later also worked on the "weighted log canonical threshold", which pertains to the integrability properties of ${\displaystyle f^{2}e^{-2c\phi }}$ for a fixed holomorphic function f.^[12]
