CUSAT IQAC Profile
https://iqac.cusat.ac.in/Web/profile_view/415/Dr.SAYUJSayuj

Sayuj Koyyappurath obtained his PhD in Plant Biology with a specialization in Plant pathology from the French Agricultural Research Centre for International Development, La Reunion. After his PhD in 2016, he joined as a Research Associate at Rajiv Gandhi Centre for Biotechnology, Kerala where he was focused on plant-pathogen interaction studies, mostly in the realm of elucidating the Zingiber- Pythium pathosystem. In 2018, he joined Dr. Sarojam Rajanis Lab at Temasek Life Sciences Laboratory (TLL) affiliated with the National University of Singapore as a Post-Doctoral fellow. At TLL he was largely involved in developing spectral signatures for abiotic and biotic stress responses for leafy vegetables using Raman Spectroscopy. Besides, he investigated and unraveled the key metabolic pathways that were altered during the compatible interaction of leafy vegetables with
Xanthomonas campestris. In 2021 he was appointed as Assistant Professor at the Department of Biotechnology.

Research Interests
1. Genome assembly and Transcriptome sequencing
2. Plant-pathogen interaction
3. Developing diagnostic markers for plant disease detection
4. Hormone signaling in plants
