Area of Research Interests

  • Conducting research in the field of reproductive biology. Experiments involving Histological, histochemical, immunohistochemical, histoenzymic, and Ultrastructural studies on the female genitalia of buffalo are being conducted to characterize the female genitalia of buffalo during different phases of the cycle and prenatal life. Immunohistochemical studies on ER and PR in female genitalia of buffalo. Immunohistochemical studies on follicular atresia in buffaloes. Spermatogonial stem cell dynamics in buffaloes. Nuclear maturation and lipid dynamics in oocytes during in-vitro maturation in buffaloes. Applied research on the anatomical characterization and decellularization of caprine heart valves
