The economy based on horticultural produce is adversely affected by infection due to plant viruses, especially those that are vector-borne and have no R-gene mediated control strategies available. My Ph. D. research work is developing around the epidemiology of viruses infecting Carica papaya. It follows on an ongoing survey for detection and characterization of diverse Begomoviruses transmitted by the whitefly Bemisia tabaci and other viruses infecting commercial and feral plants. In our lab, virus testing of symptomatic papaya plants is first conducted serologically, using Enzyme-Linked Immunosorbent Assay (ELISA). Subsequently, molecular techniques like isolation of nucleic acids with associated downstream processes like Polymerase Chain Reaction (PCR), cloning of viral genes and genomes, sequencing, and bio-informatics analysis are used. The overall purpose is to identify the virus species that persist in an area, as well as those that are visitors. Currently, drivers of persistent virus species infecting papaya in the region are not known. The epidemiological work is carried out with firm belief that it will contribute in helping out breeders and struggling cultivators. Along with my research I like to spend my time reading historical/sci-fi/romance/mystery novels, listening to gospel/rock/country/ballads/jazz/ music, and exploring the diverse culinary realm our country has to offer.

With the advent of metagenomics, microbiomes in environmental samples are getting ample attention. My M.Sc. dissertation work involved data analysis of microbial communities in sewage samples with a special focus on syntrophic cybernetics. A meticulous study of metagenome data in light of ecological contrasts and physiological profiles of bacterial groups helped me understand how sewage acts as an ecological umbrella and harbours unique microbes within. Through my forthcoming research endeavours, I intend to unravel more intricacies of microbiomes thriving in unique environmental niches. I find it profoundly equipping as it allows being a part of a ‘real time’ contemporary fictional page-turner and help to connect the dots to find ‘who and how’ the characters interact to make it to the end!

Plants play a crucial role in ensuring food security and prosperity worldwide. Since, India is primarily an agrarian economy, the need to study interactions among plants, viruses and vectors becomes important. Plant-pest interactions especially those that involve insect vectors of plant viruses that cause disease with economic impact involve complex processes and a diversity of participants. Earlier, during the course of my dissertation work, interactions with my supervisor led me to develop a keen interest in plant-pest interactions. The broad theme of my PhD. thesis is to study the interactions among host plants, Begomoviruses and their whitefly vector at the molecular level. Whiteflies, are one of the major pests that wreak havoc in the agricultural fields by transmitting Begomoviruses and other viruses leading to yield loss. My work primarily revolves around the quest for knowledge on the “how” and “why” of these interactions occurring at the molecular level. Apart from studies, I am a yoga enthusiast and have interest in painting as well as photography.

I was introduced to the area of insect-plant interactions during the fourth semester of my M.Sc. in the special paper “Molecular interactions of plants with symbionts, pathogens, and pests”. Discussions with Prof. Sudeshna Mazumdar-Leighton allowed me to delve deeper into the fascinating world of insects and their adverse impact on agricultural produce. In my Ph.D. I want to investigate the population biology of a storage grain pest Tribolium castaneum (Herbst), commonly known as the “red flour beetle”. It infests a variety of host plants like wheat, rice, millets, sorghum, barley, maize and many other products. Because of its broader host range, it poses a major threat to global food supply. We will try to determine the genetic diversity of this globally distributed pest by employing suitable molecular markers. Understanding the factors involved in shaping the population architecture will help us to devise a sustainable method to control the spread of this insect. Besides research, I am an ardent gardener. I also enjoy clicking pictures of nature in my leisure time.
