Dr. Kushan Udayanga Tennakoon

Associate Professor


Educational Qualifications: BSc (Sri Lanka), PhD (Western Australia)

Research Interests

  • Ecophysiological and biochemical attributes of parasitic plants and mycoheterotrophs, their biogeography, structural biology and mechanisms of solute transfer.
  • Restoration of degraded tropical habitats with local native plant species and investigating their physiological responses to varying environmental conditions.
  • Impacts of alien invasive plant species (i.e. holoparasites, Pinus, Acacia spp) on native flora and potential arable lands.
  • Alternative energy - Applications of native plant pigments in dye-sensitized solar cells.
