Rate My Professor Kevin Liang

Dr. Liang's research focuses on theoretical and mathematical optics, investigating superresolution imaging techniques that incorporate quantum-inspired methods, Fisher information, aberrations, and partial coherence to exceed conventional resolution limits such as the Rayleigh criterion. He received a $242,300 grant from the National Science Foundation in 2025 for the project 'LEAPS-MPS: Developing Novel Imaging Techniques and Limits with Fisher Information-based or Quantum-Inspired Superresolution,' involving undergraduate students in numerical simulations to assess resolution improvements for applications in astronomy, telescopes, microscopes, and intracellular imaging. Additionally, he has led Adelphi University student teams in NASA's Innovation and Tech Transfer Idea Competition over the past two years, advancing to Phase 2 and presenting at NASA's Johnson Space Center in Houston, Texas. His key publications include 'Supergrowth in Speckle Patterns' in Optics Letters (2025), 'Quantum Fisher Information for Estimating N Partially Coherent Point Sources' in Optics Express (2023), 'Off-Axis Aberrations Improve the Resolution Limits of Incoherent Imaging' in Optics Express (2023), 'Coherence Effects on Estimating General Sub-Rayleigh Object Distribution Moments' in Physical Review A (2021), 'Theoretical Analysis of Quantum Random Walks with Stress-Engineered Optics' (2019), and 'Effects of Defocus and Other Quadratic Errors on OTF' in Optics Letters (2017). With 40 publications and 278 citations, his contributions advance optical imaging, quantum optics, and free-form optics manufacturing tolerances.
