Dr. Dadarwal teaches courses in farm animal reproduction, including cow palpation and ultrasonography, obstetrics, and male breeding soundness evaluation to third-year DVM students. He is actively involved in fourth-year clinical rotations and coordinates key areas such as large animal imaging and neonatal management, while also participating in bovine field service and clinical rotations. At the graduate level, Dr. Dadarwal coordinates and teaches courses including Advanced Bovine Reproduction, Spermatology, and Principles in Embryo Transfer. In addition to his academic responsibilities, he provides both primary and referral clinical services for theriogenology cases, primarily in cattle, but also for small ruminants and camelids, supporting clients and field veterinarians.

Dr. Dadarwal is a clinical researcher dedicated to improving the reproductive efficiency of farm animals. His work spans various areas, including estrus synchronization, egg quality, uterine health and immunity, and breeding strategies for both heifers and cows. A major focus of his research is the postpartum period, during which the uterus recovers after birth. Dr. Dadarwal has established a research program in reproductive mucosal immunity (ReproMI), funded by NSERC. His team investigates how inflammation, immune cells, and local signaling influence uterine recovery. By identifying early markers of uterine health and dysfunction, he aims to help prevent long-term fertility issues. His research group has recently developed an in-vitro culture system using in-vivo harvested uterine cells. He is also involved in studying prenatal fetal testing in cattle. Currently, Dr. Dadarwal is focusing on the development and integration of sensor-based technologies for cattle management (funded by ADF) and the creation of 3D models using in-vivo harvested cells. Additional research interests include refining breeding soundness evaluations in rams and investigating the role of seminal bacteria in ram semen quality.

Dr. Dadarwal gained his academic teaching and clinical experience at Guru Angad Dev Veterinary and Animal Sciences University as an Assistant Professor (2002-2007, 2013-2014) and then at University of Saskatchewan as a resident (2014-2016). He has joined as a faculty member (Assistant Professor, Food Animal Theriogenology) in the Large Animal Clinical Sciences WCVM (Jan 2017) and was promoted to Associate Professor in 2025. 

He is a member of one reproductive health research group (https://research-groups.usask.ca/onereproductivehealth//index.php)
