Brief Profile
Dr. Aswati obtained her M.Sc in Biotechnology from Department of Biotechnology, Cochin University of Science and Technology (CUSAT) with II rank and earned her Ph.D (Biotechnology) in 2006 from Rajiv Gandhi Centre for Biotechnology (RGCB). She has qualified various national level exams like CSIR-JRF (among top 20% of qualifiers in 2000), GATE and ARS-NET. During her doctoral research, she received Young scientist award (Biotechnology) in the XVII Kerala Science Congress and Dr. T. R. Sahu award in XIV Annual Conference of IAAT. Following a brief tenure as Lecturer (on contract) in Department of Biotechnology, University of Kerala, she pursued her post-doctoral work at RGCB as CSIR-Research Associate. In 2008, she joined the Department of Biotechnology at Goa University as a regular Lecturer and subsequently moved to the School of Biotechnology at National Institute of Technology (NIT)-Calicut as Assistant Professor in January 2009. In June 2016, she joined CUK as Associate Professor and was subsequenlty promoted as Professor. Dr. Aswati has successfully led six research projects as Principal Investigator, funded by DBT, DST, NITC-FRG, and KSCSTE; with the DBT- and KSCSTE-sponsored projects being multi-institutional, in collaboration with RGCB and JNTBGRI, respectively.
The overarching theme of her research involves:
• Understanding the molecular defense using Zingiber zerumbet-Pythium pathosystem in view of the unique metabolic architecture and obscure information available for this wild ginger taxon
• Studying endophyte and host metabolite diversity towards development of resources for sustainable disease management
• Identifying molecular factors determining Pythium pathogenesis
She has also been the recipient of BIG-12 (Biotechnology Ignition Grant) from BIRAC (Biotechnology Industry Research Assistance Council) and has been granted a patent and sealed a trademark for a biopesticide product. She has published more than 50 research papers in peer reviewed journals and books. Six scholars have completed Ph.D under her guidance and she has mentored 28 B.Tech (Biotechnology) dissertations and over 40 post-graduate dissertations, till date. She has successfully coordinated three International conferences, one National conference and one workshop. She has also actively taken up various academic/ administrative responsibilities, whenever given a chance.
