Biography
Basundhara pursued a Bachelors of Science degree in Physics from the University of Delhi and later obtained a Masters of Science degree in Physics from Indian Institute of Technology, Bhubaneswar. For her PhD from the University of Geneva, Switzerland, she worked on bridging the gap between theoretical predictions and cosmological observations in the late Universe, specifically focusing on weak gravitational lensing and astrophysical effects like intrinsic alignments.
Before joining the University, she was a CV Raman Postdoctoral Fellow and later a DST-INSPIRE Faculty at the Indian Institute of Science, Bengaluru, where she worked on open questions such as the nature of dark energy and the current rate of expansion of the Universe.
Basundhara is interested in exploring different aspects of undergraduate teaching through active learning and inquiry-based learning in the classroom, which makes scientific pedagogy fun and approachable. In her free time, she enjoys watching films and discussing them on social media.
