Current group members

Camila Beraldo, PhD student

University of Helsinki (2020-) – Insect Symbiosis Ecology and Evolution
Co-supervised with Anne Duplouy

Pranoy MS, PhD student

Indian Institute of Science (2022-)
I am a biotechnology and biochemical engineering graduate with a passion for understanding biological systems and evolution. I will be working on poppy plants as a model system to understand the impacts of domestication on plant morphology and defensive chemistry during my doctoral studies under the guidance of Prof Saskya. I am also an aspiring and active entrepreneur dreaming of new and innovative solutions to solve challenging problems faced by humanity. you can write to me at : pranoys@iisc.ac.in

Sonali, PhD student

Indian Institute of Science (2022-)
A warm greeting to all of those who are reading this page. This is Sonali, enrolled in a Ph.D. program at the Centre of Ecological Sciences, this August. From a small town, Deoria to this premiere institute, the journey is full of excitement but has also witnessed many restless nights. After completing my graduation from BRD PG College Deoria and obtaining my Master’s degree from BHU in plant science, I developed my interest in ecology, namely their adaptation and responses to current global climate conditions. It was fun to get messed up with such an entity that is supporting our life system. So primarily, my research would revolve around global changes and their impacts on plants. Meanwhile, I would also try to find a solution to the emerging challenges as to how plants will cope with these situations. As my supervisor Prof. Saskya is been working on the butterfly-parasitoid wasp community, it is exciting to be here in her lab.

Tapasya Thapa, Project associate

Indian Institute of Science (2022-)
Born and brought up in a small city, Dehradun. Did my master’s in Biotechnology in 2018. It was my post-graduation dissertation that sparked my interest in the field of phylogenetics. Just after my masters, I joined Wildlife Institute of India, Dehradun and gained experience in conservation genetics tools and techniques. And since March 2022, I have been working as a Project Associate in Population and Community Ecology lab, Centre for Ecological Sciences, IISC, Bangalore. Here, I help with the molecular lab work and routine chemistry work. I am keen to understand the effect of the environment on the evolution of characters and the survival of these characters from the molecular point of view. Apart from extracting and amplifying DNA, I love to dance and read some good fiction. Also, a music fanatic and yes, a major Potterhead.
