Harikrishnan Vijayakumar Sreelatha is a veterinarian, who graduated from the College of Veterinary and Animal Sciences, Mannuthy, Kerala, India and he joined Sree Chitra Tirunal Institute for Medical Sciences and Technology to start working with porcine models in a drug-eluting stent pre-clinical safety and efficacy evaluation programme in 2003. During this period, he also worked on ovine and caprine models as well. Since 2005, he started to work with rodents and rabbits for various proof of concept projects. In 2009, he received the International Young Scientist Award offered by the Japanese Association of Laboratory Animal Science for his work in hindlimb ischemic rabbit model. He joined for a Master’s programme in laboratory animal science at the Department of Veterinary Disease Biology, University of Copenhagen, Denmark with scholarships and travel grants from Laboratory animals Ltd. United Kingdom, UFAW, UK, Federation of European laboratory Animal Science Associations (FELASA), EU, Scandinavian (SCAND-LAS), Swiss (SGV), and British Laboratory Animal Science Associations awards during 2010-14. Later, he joined the PhD programme at the Department of Experimental Medicine, University of Copenhagen in 2016-23. He is currently a serving member of the Committee for the Control and Supervision of Experiments on Animals (CCSEA), New Delhi, which is the statutory body regulating animal experimentation in India. He also served as a working group member to revise the syllabus for minimum standards for Veterinary Practice regulations for Laboratory Animals formed by The Veterinary Council of India, a statutory body and a member of the Health Product Screening committee of Indian Council of Medical Research (ICMR), Government of India to evaluate Phase-I clinical trials readiness of medical products and drugs. He has several International academic grants, projects and scholarships and has widely published in laboratory animal science and medicine and has over 55 peer-reviewed publications, and over 8 book chapters. His current area of interest is refinement of animal models and refinement of rodent care, handling, and housing standards. Dr. Satish Patel is working as general manager and head of Animal Research Facilities, Zydus Research Centre, Ahmedabad, Gujarat, India. He is a veterinarian and done his Ph.D in veterinary pharmacology and toxicology from Anand Agricultural University, Gujarat, India. He has been working with laboratory animals for more than 24 years. He has performed key role in establishing many laboratory animal facilities at different organizations, and among these few are GLP and AAALAC accredited. As part of research and development activities that he is leading in Zydus Research Centre, he travels and works with many foreign CROs in the USA, Canada, and Europe for preclinical studies including veterinary Bio availability and Bio equivalence studies. He has also developed many preclinical disease models, in different therapeutic areas like diabetes, inflammation, arthritis, dyslipidemia, cancer etc. using different novel methodologies and techniques. He has enormous knowledge and experience in care, management, breeding and regulatory experimentation of laboratory animals including inbreds, outbreds, mutants, transgenics (genetically modified), immune-deficient and humanized animal models, dogs and non-human primates. He has also to his credit, a few innovative products which are commercialized and, are in the market, where he has been involved in basic research and development. He also worked for B.V. Patel Pharmaceutical Education Research & Development (B.V. PERD) Centre, Hester Bioscience ltd, and Cadila Pharmaceutical Pvt ltd, Ahmedabad in the field of biomedical research and development. He has undergone several training programs on laboratory animal management, health monitoring and animal model development. He served as a working group member to revise the syllabus for minimum standards for veterinary practice regulations for laboratory animals formed by The Veterinary Council of India (VCI), a statutory body. He has published more than 25 research publications in national and international peer-reviewed journals. He is also member of few societies of veterinary science and laboratory animal science. His current area of interest is improvement of current practices of laboratory animal care and management and refining methodologies in animal experimentation.
