Liesl Nel-Themaat, Ph.D., HCLD, is a certified High-complexity Clinical Laboratory Director and Technical Supervisor with a specialty in Embryology by the American Board of Bioanalysis.
She earned her undergraduate degree in agriculture (physiology and biochemistry) from the University of Stellenbosch. As her next move, Dr. Nel-Themaat left her native South Africa to pursue her Doctor of Philosophy in animal reproductive physiology from Louisiana State University. During her Doctoral studies, Dr. Nel-Themaat was a Graduate Research Assistant for the Audubon Center for Research of Endangered Species where she worked in assisted reproductive technologies in various exotic species. Her research included intergeneric nuclear transfer cloning for use in conservation and she managed the Frozen Zoo biomaterials resource bank, a collection of cell lines from endangered species as an insurance against extinction. After graduating with her Ph.D., Dr. Nel-Themaat did a postdoctoral fellowship and MD Anderson Cancer Center in Houston, TX, where she continued her studies of the reproductive system using transgenic animal models.
All her zoology-based groundwork laid the foundation for Dr. Nel-Themaat’s expertise in embryology, andrology, and endocrinology. Since joining the University of Colorado Advanced Reproductive Medicine in 2017, she has not only been a key player in all lab activities, but also participates as faculty for the REI Fellowship Program.
Over the course of her career, Dr. Nel-Themaat has contributed to dozens of professional publications, covering topics such as development of new technologies for use in the reproductive lab, cryopreservation of sperm, embryos and eggs, in vitro fertilization (IVF), and diminished ovarian reserve. She is an active member of professional organizations including the American Board of Bioanalysis (ABB), American Society for Reproductive Medicine (ASRM), Colorado Association of Reproductive Technologists, College of Reproductive Biologists (CRB), and the Society of Reproductive Biologists and Technologists where she is the president. Dr. Nel-Themaat is among the founding members of the International IVF Initiative (i3), a non-profit global educational project for the Assisted Reproductive Technologies (ART) community.
Dr. Nel-Themaat was formally the IVF Lab Director for SGF Colorado and now IVF Lab Director and Associate Clinical Professor at Stanford University, California. When she is not overseeing the labs, you can find Dr. Nel-Themaat outdoors running, snowboarding, mountain biking, and scuba diving. She has also recently completed her Executive MBA.


Pierre Comizzoli started his career more than 25 years ago as a research veterinarian South America and Africa. He then completed a PhD in 2000 on in vitro fertilization in bovine and deer species. In 2002, he joined the Smithsonian Conservation Biology Institute in Washington, DC to develop new cryo-banking projects on gametes and gonadal tissues from rare and endangered species. This also includes the coordination of reproductive monitoring and artificial inseminations in different species (including giant pandas, clouded leopards, or Eld’s deer). He is leading since 2007 a Smithsonian-wide initiative to improve the management and use of frozen biomaterial collections within the Institution.


Professor Evelyn Telfer holds a chair in Reproductive Biology at the University of Edinburgh. She heads a research group in Ovarian Development with a particular interest in developing in vitro models to support oocyte development from immature stages in domestic species and human. Evelyn’s group has developed a culture system that supports in vitro growth of human and bovine primordial follicles to the Metaphase II stage. They are now using these models to study the potential of female germ line stem cells isolated from adult ovaries in a range of species.
Evelyn is a regular invited speaker at International meetings, she has several international collaborations and her research is funded by the Medical Research Council U.K. and The Wellcome Trust. Her group has won several awards at international meetings and in 2019 she received the distinguished scientist award from the Society of Reproduction and Fertility. Evelyn also has an interest in the Public understanding of science and contributes to workshops and delivers lectures at science festivals and other public forums. Evelyn was appointed Commander of the Order of the British Empire (CBE) in the Queen’s Birthday Honours 2021 for services to female reproductive biology and in 2022 was named the prestigious Marshall Medal awardee by the Society for Reproduction and Fertility.


Jenny Graves is an evolutionary geneticist who exploits our distant relationship to Australian animals to discover how animal genes and chromosomes evolved, and how they work. She uses this unique perspective to explore the origin, function and fate of human sex genes and chromosomes, (in)famously predicting the disappearance of the Y chromosome.
Jenny studied at Adelaide University (BSc, MSc) and the University of California Berkeley (PhD). She lectured at La Trobe University, then at ANU she founded and directed the Comparative Genomics Group and an ARC Centre of Excellence. She returned to La Trobe as Distinguished Professor and Vice Chancellor’s Fellow.
Jenny has produced three books and more than 400 research articles. She received the international L’Oreal-UNESCO prize (2006), an Order of Australia (2010) and the Prime Minister’s Prize for Science (2017). She was elected to the Australian Academy of Science (1999), and the US National Academy of Science (2019).



Dr. Bruce D. Murphy earned his BSc (Biology) and MSc (Physiology) at Colorado State University. He was awarded a PhD in reproductive biology (University of Saskatchewan), where he continued on the Biology faculty. In 1985 he founded the Reproductive Biology Research Unit in the Department Obstetrics and Gynecology, College of Medicine and served as Director until 1991. From 1991 to 2013 he was Director of the Centre de recherche en reproduction, Université de Montréal where he currently holds a joint appointment Département de obstetrique-gynecologie, Faculté de médecine. He has held visiting appointments at Cornell University, and at the Institute of Genetics, Cellular and Molecular Biology, Louis Pasteur University, Strasbourg, France and the School of Biosciences, University of Melbourne. He founded the Réseau Québécois en Reproduction (Quebec Reproduction Network, RQR) that is currently funded by federal and provincial grants. This network coordinates collaborations, sponsors symposia and provides training funds to 80 researchers in the province of Quebec. He was founder of the Canadian Consortium in Reproductive Biology,and chaired of the Institute of Human Development Advisory Board and Standing Committee in Reproductive Biology. He was Treasurer of the Society for the Study of Reproduction (SSR) 2000-2009, and served as President of that Society in 2015-2016. He is on the editorial board of five journals and served as Editor-In-Chief of Biology of Reproduction, 2009-2013. Dr. Murphy’s laboratory has been continuously funded since he began as an independent investigator for studies of diapause and embryo implantation and for investigation of ovarian function. He is author of more than 250 scientific publications on these topics and has been a plenary and symposium lecturer at several international conferences. Among the awards he has received are the SSR Distinguished Service Award, the Pfizer Award for Research Excellence and the CFAS Award for Excellence in Reproductive Medicine.

He was the organizer of the ICAR Workshop on Diagnostic Tools for Gametes and Embryos, member of the Program Advisory Committee, CIHR Training Program in Reproduction, Early Development, and the Impact on Health, invited contributor to the report of the Canadian Royal Commission on New Reproductive Technologies, and founder of Embryo-Mail.

Don is now a consultant in Reproductive Biology..


Maurizio Zuccotti is an embryologist at the University of Pavia, Italy, where he is full professor of Developmental Biology. His research focuses on the identification of the cellular and molecular factors that during oogenesis contribute to the acquisition of the mammalian oocyte's developmental competence. Thanks to an interdisciplinary approach based on tomographic and optical imaging, correlative microscopy, histochemical and molecular biology tools (e.g., spatial transcriptomics), machine and deep learning, he is dedicated to build a 4D digital model of the ovary from homeostasis to dysfunction.
He is coordinator, with Dr. Danilo Cimadomo, of a Master course in 'Biology and Biotechnology of Reproduction: from research to the clinic' organised together with GeneraLife.
