Tonghua Lin
I am a Ph.D. candidate in Supply Chain Management at Rutgers Business School, advised by Weiwei Chen. I study how firms make operational decisions under financial and behavioral constraints, combining stochastic modeling and optimization with empirical analysis.
My current work spans three areas: the operations–finance interface (inventory decisions under bankruptcy risk, valuation of cash conversion systems), platform logistics (order assignment with heterogeneous crowdsourced drivers), and healthcare operations (workforce structure and service quality in dialysis care). Papers from this work are under revision at the Journal of Operations Management and the European Journal of Operational Research.
I approach research as a builder. My strength is turning models into working systems: implementing large-scale optimization algorithms, accelerating computation (including GPU-based dynamic programming), and constructing data pipelines from messy real-world sources. I am also an active adopter of AI tooling — designing agent workflows and reusable skills for LLM-based agents — and I bring this into both my research and my teaching.
Core Competencies: Optimization (Mixed Integer Programming, Branch-and-Price, Dynamic Programming), Markov Decision Processes (MDP), Machine Learning, Causal Inference, Software Design & Engineering.
Collaboration: Actively welcoming research collaborators and coauthors.

Take a photo with me! I'll let my AI friend do a favor for us.

Modeling Liquidity and Survival: Inventory Speculation and Bankruptcy Risk
Authors: Tonghua Lin, Weiwei Chen, Xiaowei Xu
Status: Work in Progress
Studies how financially constrained firms should manage inventory when ordering decisions affect both profit and the risk of running out of cash.

Optimizing Order Assignments in On-Demand Delivery with Behavior Heterogeneity of Crowdsourced Drivers
Authors: Xinyi Huang, Tonghua Lin, Weiwei Chen, Hongyan Dai
Status: Almost Completed, Preparing for submission to Production and Operations Management
Studies how on-demand delivery platforms should assign orders when crowdsourced drivers differ in how they actually carry out deliveries.
