Rajnish Shree Raj
IISER Tirupati, MSc project IISc (June 2024-)
I am from Jharkhand. I am doing my master’s thesis in the Population and Community Ecology lab under Prof. Saskya. My interests lie in the realm of behavioral ecology and evolutionary biology. It deeply fascinates me to unravel the dynamics of the ecosystem, and I am passionate about solving the mysteries behind organism’s behavior and interactions. My current research with Dr. Prabitha Mohan in the lab focuses on studying the effect of intraspecific competition on the performance traits and resource utilization of parasitoid wasps. This work will help me to examine the complexities of parasitoid interactions and contribute to our understanding of species behavior under competitive conditions. Beyond this, I like herping, birding, and venturing out. Quality time with friends is what I always enjoy.

Gauravya Mohan
Indian Institute of Science, M.Sc. Life Sciences (August 2024-)
I pursued my bachelor’s in Biological Science at Sri Venkateswara College, University of Delhi. Growing up in Delhi, a place thought to be bereft of wildlife, was essential in my interest in ecology. It forced me to scrutinize my surroundings deeply for organisms, if only to look at the smallest plants growing in cracks in the asphalt. I worked in a project with the Wildlife Trust of India for anuran ecology and conservation at Delhi NCR, to mitigate roadkill and create awareness. Additionally, I worked on anuran behaviour and bioacoustics. I also briefly interned at the Wildlife Institute of India, working in tree identification and phenology, to develop a field identification guide. This allowed me to further explore my interests in ecology as well as build my skills in graphic design. Though I have worked with higher plants and animals in the past, I harbor a deep interest in the ecology of ferns, bryophytes and invertebrates. At the PoCo Eco lab, I wish to gain a deeper understanding of species interactions and community ecology, and expand my interests. I am certain I will be able to achieve that under the guidance of Prof. Saskya and my supportive lab mates. Besides my scientific interests, I spend my time browsing classic literature. Some of my favourite storytellers include Munshi Premchand and Saki.

Shri Avanthika J
Central University of Karnataka, M.Sc. project IISc (Dec. 2024-)
Growing up around silkworms and silk moths, I’ve always felt a special tie to insects, which made me learn more about their ecosystem dynamics. So, I did my bachelor’s in Zoology major from PSGRKCW, Coimbatore, where I worked on “Luring activity against houseflies using different essential oils” as my UG thesis; I also observed different wasp nest architecture, and I also documented the butterflies and birds of my college campus. During my master’s, I became acquainted with behavioural ecology and animal interactions, which made me join the ‘PoCo Eco Lab.’. Currently, I am working with Anaswar, a PhD scholar, on my master’s project, “Rutaceae-associated moth diversity in human-managed and wild landscapes.”.I am specifically examining and studying more about the microlepidopterans (micromoths) families associated with Rutaceae plants, their identification keys,their species richness.I am intrigued to understand the community shift of those moths in different habitats. Apart from academics, I love to do pencil sketching and painting, which I am currently doing in a digital format as cartoons and illustrations. I also love dancing and gaming.

Vandana P M
Yuvaraja’s College, University of Mysore, MSc project (Mar. 2025-)
I am from Mandya District, Karnataka.I was bought up in a small village which is rich in biodiversity having wide variety of Flora and Fauna. The internship that I did on “Thermal Biology of Cold Specialist” under the guidance of Prof. Subhash Raj Purohit in ‘Experimental Ecology and Evolution Laboratory’ at Ahmedabad University, Gujarat, invoked my interests in Ecology and Evolutionary Biology. Additionally, my fascination in studying and understanding Animal Behaviour led me to select the ‘PoCo Eco Laboratory’ for my Master’s thesis research. I am working with Dr. Prabitha Mohan on the project “Diversity of Egg Parasitoids and the association of Wolbachia”. Egg parasitoids are a diverse group of parasitic wasps that lay their eggs inside or on the eggs of other arthropods, mainly insects. I hope to gain and enhance my understanding of parasite ecology, evolutionary dynamics, and real-world applications such as biological control and disease management, that are valuable for careers in conservation biology, agriculture, epidemiology and evolutionary ecology.
