PH.D. PROJECT
In 2018, I started my Ph.D. in Plant Pathology as a member of RGE-FABI Tree Health Programme (RGE-FABI THP) and Tree Protection Co-operative Programme (TPCP).
For my Ph.D., I am investigating a serious disease recently named as Eucalyptus scab and shoot malformation. The disease was first observed in North Sumatra, Indonesia in 2014. However, the causal agent was discovered only recently as a novel species of Elsinoe. The name of the pathogen is derived from the Latin word “necatrix” (killer, murderess) to refer to the destructive impact that the disease has on its Eucalyptus hosts.
The disease is characterized by black necrotic spots that initially appear on young leaves and petioles, which become scab‐like as the lesions age. Infected trees respond to infection by producing shoots with small leaves that commonly appear feathered. Severely affected clones usually die after a number of successive infection cycles, generally over a period of 2–3 years.
The origin of Elsinoe necatrix is unknown, but evidence suggests that this is likely an area where Eucalyptus species are native. The pathogen would then have been accidentally introduced into North Sumatra where it has encountered susceptible host trees and an environment conducive to infection. In this regard, it should be considered as a high-risk pathogen and efforts should be made to prevent its spread to new environments.

M.SC. PROJECT
I first joined FABI family in 2016 as a Master student under the supervision of Prof. Michael J. Wingfield, Prof. Irene Barnes and Prof. ShuaiFei Chen. In 2018, I completed my MSc. in Plant Pathology (Cum Laude) with the dissertation entitled "New species of Calonectria and Cylindrocladiella from Vietnam, Indonesia and Malaysia".
