I am a Senior Lecturer in Plant Physiology LJMU and I am interested in all aspects of the molecular physiology of abiotic stress tolerance. I have a particular focus on water relations, salinity and heat stress in crop plants. My recent research has specifically focused on underutilized vegetables and crop wild relatives including Amaranth, and wild tomato relatives. Current projects include investigating the drought tolerance characteristics of wild and cultivated Amaranthus species and the development of molecular markers to study the genetic diversity of vegetable amaranth. I have previously held post doctoral positions at The University of Nottingham investigating carotenoid biosynthesis in tomato, and The World Vegetable Centre, Taiwan investigating drought and heat stress tolerance in tropical tomato. I have held teaching positions at The University of Nottingham, Malaysia Campus and University College Dublin.
