Dr. Mandira Katuwal Bhattarai

Mandira photoMandira received her BSc. Agriculture and M.Sc. Agricultural Entomology from Tribhuvan University, Nepal (2005-2012). During her masters, she joined the Department of Agriculture, Nepal as a plant protection officer. There she worked with farming communities providing plant protection-related extension services. Her interest includes the broad area of pest management using novel genetic tools, and host-parasite interaction.

She received her Ph.D. degree from Northwest Agriculture and Forestry University, China (2014-2018). Her research was focused on screening of entomopathogenic fungi from genera; Beauveria, Isaria, and Metarhizium for their use as biological control agents and studying the host’s enzymatic response against those strains using Mythimna separata and Tenebrio molitor as insect models.

In the Gemmell Lab, Mandira’s work is mainly focussed on genomics and microbiomics of three NZ pasture weevils; clover root weevil, lucerne weevil and argentine stem weevil. She aims to compare their genomes and microbiomes to dissect the genetic underpinnings of how these weevil pests are becoming resistant to their biological control agents. She is supervised by Professor Neil Gemmell and co-supervised by Dr. Eddy Dowle and Dr. Craig Philipps from AgResearch.

मन्दिराले बि. एस्सी. एजी. र एम. एस्सी. एजी. (किट बिज्ञान) त्रिभुवन विश्वविद्यालय, नेपाल बाट पुरा गरेकी हुन। उनले वि. सं. २०६७ देखि कृषि बिभाग अन्तर्गत बाली संरक्षण अधिकृत पदमा रही किसान समुहहरुलाई कृषि प्रसार सेवा प्रदान गर्ने अनुभव पनि हासिल गरिन्। उनको रुचि विशेष गरि शत्रु जीव बेबस्थापन, होस्ट-परजीबी अन्तरक्रिया र जेनोमिक्स र माइक्रोबयोमिक्स जस्तो नया पद्दतिमा रहेको छ।

उनले चिनको नर्थ वेस्ट कृषि र वन विज्ञान विश्वविद्यालय (वि. सं. २०७१ - २०७५) बाट कृषि कीट विज्ञान र कीट नियन्त्रण विषयमा पीएचडी डिग्री प्राप्त गरिन। उनको पीएचडी अध्धयन कीरामा रोग उत्पन्न गर्ने तीन प्रकारका ढुसीहरु; बिउभेरिया, मेटारायीजीयम र ईसारिया हरुलाई प्राकृतिक कीरा नियन्त्रण प्रयोजनको निमित्त कसरी प्रयोग गर्ने र सो ढुसीले कीरालाई आक्रमण गर्दा उक्त कीराको प्रतिरोधात्मक एन्जाइम गतिबिधिमा आउने परिवर्तनमा आधारित थियो।

हाल उनी ओटागो विश्वविद्यालय, गेम्मेल प्रयोगशाला अन्तर्गत अध्धयनरत छिन। उनको अहिलेको अध्धयन  घास बालीहरुमा छति गर्ने तीन जातीका घुन् कीराहरुको जेनोमिक्स र माइक्रोबायोमिक्समा आधारित छ। उनी जीनोम असेंब्ली, एनोटेसन र तिनीहरुको तुलनात्मक अध्धयन साथै तिनीहरुको माइक्रोबायोम अध्धयनले यी घुनहरु किन र कसरी आफ्नो प्राकृतिक सत्रुहरुलाई कम्जोर तुलयाउन सफल भईराको छन् भन्ने प्रश्नको उत्तर खोज्नेछ । उनको पीएचडी अध्धयन सुपरिवेक्षण प्राध्यापक निल गेमेल र सह-सुपरिवेक्षण डा एडी डोल र डा क्रेग फिलिप्स, एग्री अनुसन्धान बाट भैरहेको छ।
