Jiwook Jang

Jiwook Jang is an Associate Professor of Actuarial Studies in the Department of Actuarial Studies and Business Analytics at Macquarie Business School, Macquarie University. He maintains dual affiliations with the Data Horizons Research Centre and the Emerging Risks Research Centre, reflecting his expertise in both traditional and emerging risk domains.

Dr. Jang earned his B.A. in Business Administration from Sogang University, Seoul, followed by a Master of Science in Actuarial Science from City University, London, and completed his Ph.D. in Statistics at the London School of Economics and Political Science (LSE) in 1998. His academic journey includes positions as Lecturer of Statistics at LSE, Lecturer of Actuarial Studies at the University of New South Wales, and Senior Lecturer of Financial Mathematics at Bayes Business School, London.

His research program centers on developing sophisticated stochastic models for insurance and financial risk applications. He specializes in compound processes including Poisson, Cox, Hawkes, shot-noise Poisson, and dynamic contagion processes, with recent expansion into cyber risk modeling. His work bridges theoretical mathematical frameworks with practical industry applications, particularly in catastrophe reinsurance and cyber risk assessment.

Dr. Jang's publication trajectory shows a strategic evolution from foundational actuarial mathematics toward emerging cyber risks, with multiple high-impact publications in 2022-2025 addressing cyber risk frequency, severity, pricing mechanisms, and systemic implications. His research integrates mathematical rigor with industry relevance, particularly evident in his recent work on multivariate contagion processes for modeling business sector spillover dynamics.

His significant research projects include:

• Catastrophe Insurance and Asian Option Pricing with Advanced Models (2018-present)
• Quantification of cyber risk and its driving risk factors: Optus-Macquarie Cybersecurity Hub (2020-2021)
• Deed of Standing Offer - Services for Health Economics Services Panel (2015-2018)

Dr. Jang has established a robust international research network, evidenced by invitations to present at leading institutions worldwide including Imperial College London, KAIST, ETH Zurich, and multiple Korean universities. His research fingerprint confirms distinctive expertise in Shot Noise Processes (100%), Cox Processes (92%), and Cyber Risk (60%), positioning him at the forefront of mathematical risk modeling.
