Rate My Professor Haishen Yao

Dr. Yao's research contributions center on applied mathematics, with a focus on queueing theory and asymptotic analysis. Key publications include "On the Nonsymmetric Longer Queue Model: Joint Distribution, Asymptotic Properties, and Heavy Traffic Limits" co-authored with Charles Knessl (2013), "On the Finite Capacity Shortest Queue Problem" with Knessl (2011), "On the Shortest Queue Version of the Erlang Loss Model" (2008), "Some first passage time problems for the shortest queue model" (2008), "On the infinite server shortest queue problem: Non-symmetric case" with Knessl (2006), "ON THE INFINITE SERVER SHORTEST QUEUE PROBLEM: SYMMETRIC CASE" with Knessl (2005), and "Restricted Flows and the Soliton Equation with Self-Consistent Sources" with Runliang Lin and Yunbo Zeng (2006). He has received PSC-CUNY research awards, including funding for "The Time-Dependent Solution of Longer Queue Problem." Dr. Yao mentors undergraduate research projects on topics like eigenvalues of Markov chain transition matrices and barrier problems in dice sums, participates in the CUNY Research Scholars Program, and organizes math challenges for students.
