主講人介紹：主要研究方向為應用動力系統及其在復雜生物系統的應用。論文發表在Journal of Nonlinear Science, SIAM Journal of Applied Mathematics, IEEE Transactions on Automatic Control, Journal of Differential Equations, Proceedings of the Royal Society of Edinburgh-A, Journal of Mathematical Biology, Scientific Reports, Chaos, Bulletin of Mathematical Biology, Journal of Theoretical Biology, Ecological Complexity等主流應用數學以及理論生態學雜志。近年來對具有季節驅動或年齡結構的復雜系統以及復雜網絡上的疾病傳播動力學感興趣。曾獲加拿大MITACS博士后基金。近期研究受國家自然科學基金和香港特別行政區大學教育資助委員會資助。
內容介紹：This talk presents a mechanistic model for describing the spatial dynamics of tick-borne diseases by considering systemic transmission, seasonal climate impacts, host movement as well as the co-feeding transmission route. The net reproduction number for tick growth and basic reproduction number for disease transmission are derived, which predict the global dynamics of tick population growth and disease transmission. Further numerical simulations will also be presented in the talk to not only verify the analytical results, but also characterize the contribution of co-feeding transmission route on disease prevalence in a habitat and the effect of host movement on the spatial spreading of the pathogen. This is based on joint work with Xue Zhang and Bei Sun from Northeastern University.
