Molecular Endocrinology and Reproductive Physiology
My research interests are focused on spermatogenesis and its regulation at anatomical, cellular and molecular level using mouse and/or rat as animal model.
I am actively engaged in evaluating reproductive toxicity of emerging environmental contaminants like brominated flame retardants (BFRs), which are potential threat to human health, using a combination of in vivo, in silico and molecular approaches to investigate as to how the male progeny responds to these contaminants after maternal exposure during lactation.
My research interest further lies in exploring the effect of neonatal hypothyroidism on male reproductive health especially in terms of glucose homeostasis in mouse testis and these experimental models illustrate the thyroid control of testicular differentiation and metabolism during development.
Recently, I am trying to elucidate the role of certain neuropeptides and cytokines in regulation of spermatogenesis.
1. Defining the role of Orexin B, a novel hypothalamic neuropeptide, in regulation of spermatogenesis in mouse model (2020-2022). Funded by: DST-SERB, India (Rs. 29,26000/-).
2. Chemical profiling and evaluation of antifertility potential of aqueous leaf extract of Allamanda cathertica L. in male laboratory mice (2021-2023). Funded by: RSM grant, Central University of Punjab (Rs. 3,00000/-).
