Dr. Harikrishnan is a laboratory animal Veterinarian. After completing his graduation from the College of Veterinary and Animal Sciences, he joined SCTIMST (An institution of National importance by an act of Indian parliament 1980, under the Department of Science and Technology, Govt of India) in 2003 and was into coronary stent evaluation project in porcine coronary artery model. After working with large laboratory animals for a while he joined the division of Laboratory animal science in 2005 and is still working with small animal models. He developed several small animal surgical models like the rabbit hindlimb ischemia model, osteoporosis in rats, spinal cord injury in rats, intervertebral disc degeneration in rabbits etc to name a few. For his work on hindlimb ischemia, Dr. Harikrishnan was awarded with the Japanese Association of Laboratory Animal Science award in 2009 in Kyoto, Japan.In 2014, Dr. Harikrishnan completed Master of Laboratory animal science postgraduation from University of Copenhagen, with prestigious scholarships from Laboratory Animals LTD. UK, UFAW UK, SCAND-LAS Sweden, LASA UK, SGV Switzerland, Novo Nordisk and Lundbeck, Denmark. Currently, he is a member of CCSEA, Govt. of India, New Delhi which is a statutory body regulating animal experiments in India. He is a PhD scholar at the Department of Experimental Medicine, University of Copenhagen doing work with refinement of animal model for spinal cord injury and nearing the completion of the project by the end of 2023.Dr. Harikrishnan has over 55 peer reviewed publications and several book chapters. 

Collection Overview

This Methods Collection focuses on creating animal models using surgical approaches in biomedical research. Significant progress has been made in the field of surgical animal models, leading to numerous publications. However, to enhance reproducibility and accessibility, video-based publications are proposed for several of these complex programs. By providing detailed visual demonstrations, other researchers worldwide can easily replicate these techniques, addressing concerns related to the reproducibility crisis in pre-clinical biomedical research.


The collection will specifically cover complex procedures such as:


1. Thoracic vertebral laminectomy for spinal cord injury in rats using a motorized approach.

2. Thoracotomy in rats.

3. Coronary ligation.

4. Implantation of electrodes in the skull.

5. Sleep research in rats.

6. Other related works, including the surgical induction of parkinsonism.


Despite previous publications on these techniques, their novelty and complexity will attract considerable interest from researchers seeking to view and replicate them. The goal is to contribute to the scientific community's knowledge base by providing comprehensive and accessible resources for advancing pre-clinical research.
