Peter Ho, born in Singapore in 1971, received his PhD from University of Cambridge in 2001 (thesis advisor, Professor Richard Friend) for work on polymer organic semiconductor devices. He subsequently won a junior Research Fellowship from St John’s College, Cambridge, during which tenure he also moved to Bell Laboratories, New Jersey, as visiting scientist.  He returned to Department of Physics, National University of Singapore in 2004, and set up an integrated research laboratory (ONDL) to investigate the science and technology of polymer organic semiconductors together with Lay-Lay Chua, who later joined Department of Chemistry. Innovations from this laboratory include: generalized n-type organic field-effect transistors (2005), printable low-temperature nano-metal inks (2007), semiconductor-grade photocrosslinkers and morphology-stabilized devices (2010, 2012), broadband optical limiting formulations (2011), self-release 2D material transfer technique (2013), and self-compensated doped polymers with ultrahigh and ultrahigh work functions (2016–2017).  Peter’s research seeks to leverage these developments to gain insights into the physics and design of solution-processed devices, including organic light-emitting diodes, transistors, solar cells, and graphene–organic hybrids.
