Hiew was hired in January 2023 as an assistant professor in the Pharmaceutics Program of the Pharmaceutical Sciences and Experimental Therapeutics Department (PSET). Her research interests center on pharmaceutical oral solids, including pre-formulation, formulation, and manufacturing science of drug products, particularly related to tablets and pellets.  

Dr. Tze Ning Hiew received her Bachelor of Science (Pharmacy) and Ph.D. degrees from the National University of Singapore, Singapore. Prior to graduate school, she completed her pre-registration training at Tan Tock Seng Hospital, Singapore, and subsequently worked as an inpatient pharmacist in the same hospital.

During her Ph.D. studies, Dr. Hiew's thesis focused on the role of water–excipient interactions on product stability. While excipients used in oral dosage forms are commonly assumed to be inert substances since they do not play a critical role from the pharmacotherapy perspective, the physicochemical properties of the excipients could have a profound impact on the performance of the dosage form.
