Joshua Yap has started teaching in universities in 2004. He has been teaching modules with various subjects from seed science to cell biology, plant biotechnology, biodiversity, cryopreservation and environmental science. The modules that he teach ranged from foundation level to postgraduate level. His expertise is plant conservation.

Current Research

Currently Joshua's research focuses on plant tissue culture of medicinal plants, seed science and technology of Malaysian minor fruits, phytochemical studies (anti-microbial, anti-diabetic, etc) leading to drug discovery.

His research work started off with the interest of propagating plants via in vitro techniques, and later extended to using in vitro technologies as a platform to cryopreserve various non-seed-producing, recalcitrant seed and vegetatively propagated plant species. He had developed several ground breaking technologies in conservation various minor fruits with recalcitrant seeds (unable to be dried and kept in seed bank) including modified encapsulation and vitrification techniques.

In recent years, Joshua had ventured into manipulating the in vitro grown plants and callusses to produce useful secondary metabolites. This requires him to go into phytochemical studies and make comparisons between field grown and in vitro grown plants.
