Biographic Sketch:
I am presently serving as an Associate Professor at the Department of Microbiology, Central University of Tamil Nadu, India. Prior to this role, I held a position as a Research Assistant Professor at Hong Kong Baptist University (HKBU) in Hong Kong. During my tenure at HKBU, my responsibilities encompassed both teaching and research endeavours, with a primary focus on microbiology and neurodegenerative diseases. I earned my doctoral degree in fungal biotechnology from the University of Hong Kong (HKU) in 2004. During my time as a PhD fellow at HKU, I had the privilege of gaining valuable insights into fungal taxonomy and diversity under the guidance of the distinguished mycologist, Professor Kevin D. Hyde. Furthermore, I hold Master of Science and Master of Technology degrees, which I acquired from the University of Madras and the Indian Institute of Technology in 1998 and 1999, respectively. During my initial postdoctoral training at the Vaccine R&D Centre at the National Health Research Institutes in Taiwan (2005-2006), I actively contributed to a project titled "Identification of an alternative receptor for the SARS CoV virus." Subsequently, I sought to further enhance my expertise in neuroprotective strategies for addressing neurodegenerative diseases, prompting my decision to assume a postdoctoral fellow position at the School of Chinese Medicine at HKBU from 2006 to 2012. Throughout this tenure, my focus as a postdoctoral fellow was dedicated to unravelling the molecular intricacies of Alzheimer’s and Parkinson's diseases while validating potential therapeutic targets for Alzheimer’s disease treatment. In addition to my research pursuits, I have significantly contributed to laboratory management and provided guidance to PhD students, postdoctoral fellows, and senior research assistants across various research topics. In recognition of my achievements, I was honoured with an outstanding research award in fungal biotechnology from the Venus International Foundation in India in 2022. My research contributions are also underscored by the publication of 49 papers in peer-reviewed journals, reflecting an H-index of 28. Additionally, I have secured two patents in the United States and two in China, along with receiving nine extramural grants from institutions in Hong Kong and India.
