MEET the Organizing Committee 


Dr. Giovanna Massei serves as Director of the Botstiber Institute for Wildlife Fertility Control Europe office and a Senior Researcher at the University of York, UK. For 25 years Giovanna has led research on wildlife management in the UK and overseas. Giovanna received her PhD from the University of Aberdeen (UK). Her research  interest focus on fertility control to manage wildlife and free roaming livestock and on the ecology and population control of wild boar. Giovanna published circa 150 scientific papers and popular articles and she’s an Associate Editor for the journal Human Wildlife Interactions.


Stephanie Boyles Griffin currently serves as the Senior Program Director in the Wildlife Protection Department at the Humane Society of the United States and as Chair of the Advisory Committee for the Botstiber Institute for Wildlife Fertility Control.
For over 25 years, she has worked with federal, state, local, and tribal agencies, non-governmental agencies, industries, academia, and policymakers to develop and advance the use of humane, effective, and sustainable methods for mitigating human-wildlife conflicts and promoting coexistence. She served as a Commissioner on the Maryland Wildlife Advisory Commission from 2011-2022 and currently serves on the Free-Roaming Equids and Ecosystem Sustainability (FREES) Network’s Steering Committee. She also serves as an Associate Editor for the journal Human Wildlife Interactions and recently served as a guest editor for a special issue of Wildlife Research on wildlife fertility control.
She holds a BA in Biology from Notre Dame of Maryland University and an M.S. in Environmental Science from Christopher Newport University. Her research has focused on assessing the efficacy, feasibility, fiscal and ecological benefits associated with installing and maintaining water flow control devices to mitigate conflicts with beavers on roadways in Virginia and using fertility control methods to manage federally protected wild equid populations in the U.S.

Léa Badoz 

After obtaining her Master’s Degree in International and European Environmental Law in 2017, Léa has worked with environmental organizations such as IUCN and BirdLife on various environmental issues ranging from mangrove governance to wildlife crime. Aware of the necessity to align policy and science, she is completing an MSc in Wildlife Biology and Conservation. Since 2021, Léa has been Programme Officer in the Wildlife Programme of Eurogroup for Animals exploring legislative and policy improvements for the welfare of wild animals across the EU. She is interested in finding innovative solutions to change mindsets and promote animal welfare as a condition for successful conservation policies.


Dr. Veronica ‘Ronnie’ Cowl is the Reproductive Biologist for Chester Zoo, UK and the European Association of Zoos and Aquaria (EAZA), the Netherlands. Dr. Cowl has worked in wildlife fertility control for 8 years, focusing on the application in ex situ managed animals. Dr. Cowl coordinates the activities of the EAZA Reproductive Management Group, which supports European ex situ breeding programmes by providing specialist advice in reproductive management. Alongside partners in the USA, she manages the ‘Contraception Database’, which holds over 56,000 records of contraceptive use in global zoos and aquaria and is used to develop contraceptive recommendations for managed wildlife. She holds a PhD in Animal Biology from the University of Manchester, UK.


Kay Haw is the director of the UK Squirrel Accord. A partnership of 45 signatories working together to protect the UK’s red squirrels and broadleaf trees from the negative impacts of introduced grey squirrels, including developing a grey squirrel oral contraceptive. Kay has a strong background in woodland ecosystem and invasive species issues, and a keen interest in human-wildlife conflicts and science communications. She was creator and editor of the Woodland Trust’s Wood Wise publication, which shares sector-wide best practice, and is now a member of the Botstiber Institute for Wildlife Fertility Control’s Science Communications Working Group. She is also a previous chair of the Wildlife and Countryside Link Invasive Non-Native Species Working Group. Kay is currently studying part time for a master’s degree in applied wildlife conservation at the University of the West of England.


Dr. Jens Jacob studied ecology and zoology in Jena, Germany and Miami, FL, USA. Since starting his PhD in 1997, he focused on applied rodent research. Following a 4-year position at CSIRO Wildlife Research (Australia), he became the leader of the Rodent Research Group of Julius Kuehn-Institute (Federal Ministry of Food and Agriculture) in Münster, Germany.
His research interests include 1) rodent population management that is ecologically and economically sustainable in various systems and various regions of the world, 2) assessing and mediating risk associated with rodent management and 3) the ecology of rodent-borne pathogens to help to take early and optimal action.
Dr. Jacob has published >150 scientific articles, chairs expert groups and is subject editor vertebrates for international peer-reviewed journals.


Dr. Manel Lopez-Bejar is a leading researcher and academic in the field of veterinary medicine, focusing extensively on animal welfare and fertility control. As the Dean of the College of Veterinary Medicine at Universitat Autonoma de Barcelona (UAB), he brings a profound commitment to advancing animal health and welfare through innovative research and education. Dr. Lopez-Bejar’s work has significantly advanced the understanding of the physiological and endocrinological aspects of animal welfare. His research on stress endocrinology has contributed to developing better welfare practices across various animal species, particularly in understanding how stress affects reproductive health and behavior.
His expertise also extends to fertility control, where he has pioneered several techniques that enhance reproductive efficiency and management in domestic and wildlife populations. This includes significant contributions to assisted reproductive technologies, which have implications for conservation efforts and the sustainable management of animal populations.
With over 250 peer-reviewed articles, Dr. Lopez-Bejar has a prolific output that underscores his leadership in these critical areas. His role as head of the ERPAW Research Group (Endocrinology, Reproductive Physiology and Animal Welfare Research Group) and membership in the multidisciplinary research group on Human and Animal Infertility of Barcelona (GRI-BCN) further highlight his influence and commitment to multidisciplinary approaches in veterinary science. Dr. Lopez-Bejar’s work not only enriches academic knowledge but also fosters practical solutions that improve the lives of animals globally, reflecting his dedication to the One Health initiative and animal welfare.


Andrea Monaco serves as a researcher at the National Institute for Environmental Research (ISPRA) in Italy. He has participated in numerous national and international projects in the field of conservation and management of large mammals and alien species, often with a focus on human-wildlife interactions. Currently, Andrea supports national health authorities in the management of the African swine fever epidemic. Andrea is a member of the IUCN Invasive Species Specialist Group and one of the founders of the Large Mammal Management Group of the Italian Mammal Society. He is also involved in science outreach and communication. In addition, Andrea teaches at the masters level at the University of Insubria. He studied Natural Sciences at the University of Milan and continued his studies at the Universities of Siena and Rome.


Antonio Varcasia is professor of Parasitology and Parasitic Diseases at the University of Sassari. His research activity is focused in diagnosis, epidemiology and molecular parasitology of Cestodes Zoonosis, in parasitic diseases of domestic animals and wildlife with over 135 international scientific publications.
