Graduate Education

Ph.D in Architectural Sciences with a Concentration in Lighting: Research Projects

Students enrolled in the Ph.D. program undertake unique research under the guidance of a faculty advisor. The doctoral thesis is considered the crowning achievement of the study.

Solid-State Lighting Research Projects

Students working in the area of Solid-State Lighting (SSL) explore optical, electrical, thermal, and materials issues to overcome some of the challenges faced by the SSL industry and further the science and engineering in this field. Sample research topics of past and present students include:

  • IoT: Remote monitoring of LED lighting system performance
  • Analysis of electrical and thermal parameters of InGaN-based LED packages with aging
  • Optimizing the performance of remote phosphor LEDs
  • Light extraction analysis of light guides used in edge-lit LED systems
  • Understanding heat transfer mechanisms in recessed LED luminaires
  • Mathematical model to analyze phosphor layer heat transfer of an LED system
  • Effect of thermal stress and short-wavelength visible radiation on phosphor-embedded LED encapsulants
  • Defining phosphor luminescence property requirements for white AC LED flicker reduction
  • Estimating the average junction temperature of AlGaInP LED arrays by spectral analysis
  • An accelerated life test method for LED drivers
  • Improving the performance of mixed-color white LED systems by using scattered photon extraction

Light & Health Research Projects

Students working in the area of Light & Health conduct basic and applied research to explore the many ways in which light affects, and can be used to improve, health and wellbeing in the general population and in special groups, such as individuals with Alzheimer's disease, shift workers, and infants in the NICU. Sample research topics of past and present students include:

  • Influence of blue and red light on melatonin suppression
  • Investigating the change in spectral sensitivity in human circadian phototransduction
  • Light and human performance
  • Measuring light for the circadian system
  • The impact of computer screens on melatonin suppression
  • Strategies for optimizing light therapy efficacy in Alzheimer's disease patients
  • Light and alertness during the daytime: keeping alert in an office environment
  • Brightness perception and melanopsin
  • The effects of daylight and high correlated color temperature on performance
  • Circadian rhythm control with active lighting
  • Alerting effects of light: implications for railway transportation
