Research interests:

My broad research interests lie in understanding:

  1. Endocrine, metabolic and molecular interactions coordinating physiological (homeostatic/homeorhetic) adaptation in key metabolic tissues during pregnancy and lactation, and delineating the aberrations induced by exposure to altered gravity.

  2. The biochemical and molecular constituents of an oocyte/embryo endowed with capacity to develop. Specifically, identify constituents that can aid in predicting developmental capacity and serve as reliable selection markers for assisted reproductive technologies.

  3. Molecular and cellular developmental chronology of a placenta, in particular, the cross-talk at the fetal, maternal and placental interface.
