In the Nursery of the National Tropical Botanical Garden (NTBG) Lawai, Kauai, Hawaii, USA
Over the last six years our focus has been the propagation of  endangered and unique species: the Amborella, an archaic species from New Caledonia, several species of the Cyanea genus endemic to Hawii and a new Kadua species,endemic to Kauai, nominally called the Haupuensis, after the region where it was found.

Cyanea BlossomCyanea: A project to enable three species of this endangered Hawaiian endemic genus to set seed

Amborella blosssomAmborella: A project to produce seedlings of an archaic flowering plant.

In Hawaii and the Islands of the South Pacific
For over fifteen year we have built mathematical and computer models of the chemical and biological processes that occur in
quarantine heat treatment of fruit (with colleagues at the University of Hawaii, the USDA Hilo, HORT (NZ), New Caledonia and MARDI, Malaysia).
