Prof. Dinnyes has been working on embryology, cloning and stem cell biology since 1985. Following his graduation in 1989 he worked as staff veterinarian at the Veterinary University of Budapest. He has been a Fulbright Scholar in the Smithsonian Institution, National Zoo, Washington D.C., visited Cornell University, Ithaca, NY and worked at the Univ. of Connecticut, Storrs, CT (1997-99) where he achieved major results in somatic cell nuclear replacement in cattle, rabbit and pig. He has worked in leading institutions in Belgium, Japan, New Zealand, China, UK. In 2000 Prof. Dinnyes joined the cloning team in Roslin Institute, BBSRC, Edinburgh, UK (the „Dolly team”) as team leader, under the guidance of Sir I. Wilmut and had a key role in production of the first gene knock-out lamb, and the first cloned piglet in Europe. After returning to Hungary he established the academic team which produced the first Hungarian cloned mice and rabbit for biomedical purposes, first in the Agricultural Biotechnology Center, Godollo, then as full professor from 2008 at Szent Istvan University, Godollo and from 2018 at Szeged University, Faculty of Medicine. Between 2008-16 he worked as full professor (0.2 FTE) at the Veterinary Faculty of Utrecht University, The Netherlands. Since 2005 as founder and CEO, leading a team of over 20 researchers in BioTalentum Ltd his main research activities are focusing on biotechnology, including animal and human stem cell research, transgenic cellular and animal models, iPS cell generation and differentiation for biomedical, toxicology and pharma purposes. Currently he is focusing on development of new pluripotent stem cell lines from different species, including mouse, rabbit and human and their differentiation towards cardiac, neural, beta-cells and other cell types, including 3D neural structures for disease modeling, drug development and in vitro toxicology. Another line of his current research is focused on epigenetic changes in early development (in animal models and human ART, obese or diabetic mothers) on adult diseases, co-morbidities and longevity. He has coordinated numerous national and international projects among them 14 EU FP6/7/H2020 projects, mobilising more than 70 M EUR funding. He is actively involved in advancing the biotech industry, being founder of SMEs and board member of the Hungarian Biotechnology Association and the Hungarian Innovation Society. For his pioneering and entrepreneurial work on genetic reprogramming technology, he has received the highest innovation award (“Denis Gabor Award”) in Hungary in 2013. He is member of the Academia Europaea and Honorary Professor of Sichuan University, China.
