This allows him to contribute his expertise to a different academic environment while fostering international collaborations in the field of forestry. Overall, his experience as a senior lecturer, combined with my research contributions in tropical agriculture, forestry and pteridology, has allowed him to make meaningful contributions to the academic community and advance our understanding of the plant kingdom's diverse aspects.
