Rate My Professor Haishen Yao

Haishen Yao serves as Professor and Chairperson of the Department of Mathematics and Computer Science at Queensborough Community College, part of the City University of New York. He earned his Ph.D. from the University of Illinois at Chicago in the Department of Mathematics, Statistics, and Computer Science in 2004. His doctoral dissertation, titled "Asymptotic Analysis of the Infinite Server Shortest Queue Problems," was supervised by Charles Knessl. At Queensborough Community College, Dr. Yao has advanced from Assistant Professor to his current leadership position, managing departmental teaching schedules, office hours, and serving on committees such as the Honors Committee. His contact details include office S-227 and phone (718) 281-5204.

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.
