Associate Professor David Lee leads the Acacia, Backhousia, Corymbia, Eucalyptus, Grevillia, Khaya and Santalum tree improvement programs in northern Australia. His tree improvement and taxa site matching work has resulted in a change in the hardwood tree varieties grown, commercialisation of new species and development of hardwood plantations in new regions in Queensland, South Africa and Brazil. David currently focuses on breeding, disease tolerance and wood property characterisation of Corymbia species and hybrids, Eucalyptus cloeziana, Backhousia citriodora, Khaya senegalensis and Santalum lanceolatum.

Across the projects David manages, the following has been achieved in the last 10 years.
- Over $11 million (AUD) in competitive grants 400K; DAFF Forest Industries Climate Change Adaptation Fund $600K; Queensland Government Smart State Funds $5.5M; Queensland Government Plantation Hardwood Research Fund $1.7M); RIRDC Backhousia $160K; Forest and Wood Products Association: Southern Pine Resource Characterisation [Pinus caribaea and elliottii and their hybrids] $2.6M.
- Genetic bases have been established and managed for 8 species with potential in the region as plantation species.
- Extensive taxa trials have been established and data collected and report on the optimal matching of species to sites, the climate of tomorrow and build baseline data for development of process based physiological models of tree growth for the tropics and subtropics
- Controlled crossing and hybrid testing programs for the production of Eucalyptus and Corymbia hybrids have been successfully developed with over 60 ha trials established and gene flow studies initiated;
- Experiments have been initiated to screen Puccinia psidii disease tolerance for key Myrtaceous species;
- Innovative technologies have been developed (e.g. molecular, acoustic, ultrasound and infrared spectroscopy) to understand the biology, fast track the genetic improvement and understand the wood properties and value of the Eucalyptus, Corymbia, Santalum and Southern Pine species.
