Zhao Chen

Dr. Zhao Chen serves as an Associate Professor in the Department of Mathematics within the School of Arts and Sciences at New York City College of Technology, City University of New York (CUNY). He holds a Ph.D. in Mathematics from the CUNY Graduate Center (2000) and teaches a comprehensive range of courses from developmental mathematics (MAT063) to advanced topics including cryptography research projects in upper-level classes.

His scholarly work centers on symbolic and numerical computations, with deep specialization in structured matrix algorithms, displacement structures, and efficient polynomial root-finding methods. Chen's research bridges theoretical mathematics and practical computational applications, consistently focusing on accelerating solutions for linear systems and matrix operations through innovative preprocessing techniques and displacement-based frameworks.

Analysis of his publication history (1998-2011) reveals sustained contributions to structured matrix theory, particularly Cauchy-like and Toeplitz systems. His work demonstrates progressive refinement from foundational displacement structures to practical algorithmic implementations, predominantly published in numerical analysis journals and high-performance computing conferences. Key themes include recursive factorization methods, operator theory applications, and polynomial division approximations.

Chen actively contributes to educational infrastructure through co-development of campus-wide software systems: the MMT scheduling tool (with Alexander Rozenblyum), Advisement Registrations Schedule (with Rozenblyum, Sandie Han, and Henry Africk), and Random Generating Exams software (with multiple collaborators). These projects showcase his commitment to integrating computational research with institutional service while supporting student learning through applied cryptography projects.
