cesar's expertise in agricultural entomology, genetics and wildlife ecology is backed by a team of specialist scientific consultants, many of whom are PhD qualified with a wealth of experience working to Australian and international standards. Our team has a combined total of over 30 years consulting experience and more than 80 years experience in science and research. We apply the highest scientific rigour to every client project, with our team having published over 150 peer-reviewed articles in national and international science journals.
cesar has strong collaborative links with several high-calibre research and government organisations, in particular the University of Melbourne and the Bio21 Molecular Science Institute. Our close association with the University of Melbourne provides connections to world-leading scientists and cutting-edge facilities. We also work with a number of expert consultants, providing cesar with access to a range of specialised skills and equipment.
cesar has a comprehensive range of field and laboratory equipment at our disposal. Both divisions of cesar utilise the latest equipment and facilities to provide a complete service to our clients. Our equipment and facilities include:
