Research interests:

  • Greenhouse-, high tunnel- and controlled environment crop production
  • Plant growth in response to light intensity, quality, day length and the use of light-emitting diodes (LEDs)
  • Energy efficient production techniques in greenhouse- and season extension environments
  • Crop growth, development and productivity under large high latitude seasonal variations in temperatures, light levels and day lengths
  • Development of guidelines to optimize vegetable, small fruit and floral crop production
  • Environmental plant physiology as it applies to commercial horticulture at high latitudes

 Current research programs:

  • Alaska high tunnel, greenhouse and controlled environment production  (USDA-Hatch, 2013-2017) 
  • Controlled environment horticulture for Alaska  (USDA-Hatch, 2007-2013)
  • Develop and integrate components for commercial greenhouses (NE-1035 multi-state project, 08-13)
  • Controlled environment use and technology  (NCERA-101 multi-state project, 2011-2016)
  • Resource management in commercial greenhouses  (NE-1335 multi-state project, 2013-2018)
