Dr. Nandini Rajamani
Assistant Professor

  • 537 F9926 e1460344604160 1024x576

Nandini’s research interests include examining the ecology of species, and understanding adaptations and processes, particularly with respect to environmental (eg: climate change, production, and human-altered landscapes), and historic (eg: trade, collections) factors. Her lab works primarily with small mammal systems. Outside of research, she is involved in several initiatives to promote and communicate science to students, researchers, administrators, and the wider public.

Aravind P S

PhD Student

  • Aravind

Aravind is broadly interested in behavioral ecology and invasion ecology. Currently, he is studying the occurrence and behaviour of palm squirrels in the Western Ghats in response to invasive plantations and native vegetation profile. In the past, he has examined changes in the distribution of the invasive plant Lantana camara and its impact on native vegetation, using a 21-year long dataset. His previous experience with animal behaviour includes examining the reproductive behavior of field crickets. Aravind enjoys exploring new landscapes and documenting experiences.

Harsha Kumar

PhD Student

  • Harsha

Harsha’s interests broadly lie in ecology, evolution, animal behavior and natural history. The Trans-Himalayas of Ladakh pose some of the most unique and harshest environments to animals that live there. During his PhD, he is studying behavioral and physiological adaptations of pikas to hypoxia and cold using a combination of field experiments, comparative phylogenetics and genomics. He has previously studied the behaviour of zebra finches and crickets at IISER Pune and CES, IISc. He has been a butterfly watcher since he was a child and finds insect systems fascinating enough to consider working on them in the future. He spends most of his free time outdoors watching and photographing creatures.

Manzoor Ahmad Dar
PhD Student

  • Manzoor

Manzoor is broadly interested in feeding ecology and invasion biology. His current research focuses on understanding the diet of the ‘Critically Endangered’ Kashmir Stag (Hangul) in Dachigam National Park, using D.N.A metabarcoding techniques, under the joint supervision of Dr. Manzoor A Shah, Associate Professor in Botany at the University of Kashmir, and Dr. Nandini Rajamani. Manzoor’s past research includes the study of the impact of the invasive weed Iberian knapweed on native plant diversity.Outside of research,Manzoor is very interested in Apple cultivation, and loves playing cricket.

  • Nivetha1

Nivetha is interested in studying the genomic and behavioral basis of evolutionary adaptations. For her PhD, she is studying the evolution of coat color adaptation and pigmentation diversity in rodents, including squirrels in India, using image analysis and bioinformatics tools. She is also part of projects examining morphological variation in small mammals using museum specimens, and variation in acoustic behaviour in palm squirrels using field recordings. She has parallel interests in communicating environmental and eco-political issues in the Tamil language.

  • Rakesh

Rakesh is broadly interested in animal cognition, behavioural ecology and urban biodiversity. For his PhD, he plans to study behavioural adaptations in palm squirrels in response to urban changes. Previously, he has worked with BNHS to understand the impact of urban development on the population and behaviour of migratory waterbirds; and at IISER Berhampur, he explored the reproductive behaviour of Drosophila. In his free time, you can find him birding and capturing photos of wildlife; apart from that, he enjoys listening, composing and producing music.

Rigzen Mingyur


  • Mingyur

Mingyur’s interest lies in environmental science. He has worked at the Himalayan Institute of Alternative(HIAL), Ladakh for the past three years. During his time at HIAL, he worked on various projects including the construction of ice stupas or artificial glaciers in Ladakh to address the acute water shortages in some villages in Ladakh, rehabilitation of Kulum village, and on developing and executing the Himalayan Farmstays programme in Ladakh. In his free time, Mingyur likes watching birds and reptiles, and loves to play ice hockey.

Senan D'Souza


  • Senan3 1

Senan’s research interests lie in ecology and biogeography. He works on documenting the occurrence of small mammal assemblages, primarily in extreme habitats of the Trans-Himalayas, but also in other landscapes like the Eastern and Western Ghats. He identifies environmental predictors to understand how species have evolved to specific conditions, and how climate change and anthropogenic pressures could impact species in the future. Senan’s other interests include bird-watching and wildlife photography, and he is always looking for the next mountain to climb.

Swati Udayraj

PhD Student

  • IMG 20210506 085547

Swati is primarily interested in understanding species interactions, landscape ecology and conservation biology. Her doctoral research is focused on understanding the impacts of resource availability on species numbers, foraging, and other associated behaviours in palm squirrels along an urbanisation gradient. She is also part of a project examining genetic connectivity across marmot populations in Ladakh, and has previously worked on understanding the genetic structure of Asian elephant populations. Outside of research she is interested in wildlife photography and doodling.
