Dr Nina Zhu, PhD, MPH, MSc, BEng, is the Research Associate in Health Systems and System Dynamics in the National Institute for Health Research (NIHR) Health Protection Research Unit (HPRU) in Healthcare Associated Infections and Antimicrobial Resistance (HCAIs & AMR).


System Dynamics modelling

Nina's research in the Organisational Change, Health Economics and Evaluation Theme in the HPRU primarily focuses on applying System Dynamics (SD) modelling to examine doctors’ and patients' decision-making processes to inform design, implementation, and evaluation of antimicrobial stewardship (AMS) interventions. She aims to establish meta-methodology to help identify and develop optimal systems thinking tools, combined with other simulation methods, including discrete event simulation (DES), and agent-based modelling (ABM), to solve real-life problems in system management in general.

She is the SD modeller and quantitative data analyst of the ESRC funded multi-national research project, ASPIRES (Antibiotic use across Surgical Pathways - Investigating, Redesigning and Evaluating Systems), to model the impact on patient, health systems, and health economic outcomes of interventions proposed to optimise antibiotic use along surgical pathways. 

Before joining HPRU, she was a visiting researcher at Harvard T. H. Chan School of Public Health. She has employed the same modelling methodology to investigate evidence in health system strengthening and healthcare intervention evaluation in low- and mid- income countries (LMICs).

Applied data linkage and MODELLING

Nina is currently conducting the investigation project in the AMR/HCAI Division at Public Health England (PHE) to assess underlying risk factors of Gram-negative blood stream infections (GN BSIs) in England. This is for the first time national scale patient-level data linkage has been performed using prescribing data, laboratory surveillance data, and hospital administrative data to produce baseline description and regression models for GN BSIs. 


Nina has a PhD in Clinical Medicine Research. Her doctoral research focused on investigating factors influencing doctors' antibiotic prescribing decision-making processes in secondary care using System Dynamics. Nina has a Bachelor of Engineering (BEng) (hons) of Biomedical Engineering and a Master of Public Health (MPH) from Imperial College London, and is a candidate of MSc in Economic Evaluation in Healthcare from City, University of London.
