Jan Pluháček

Co-Chair/EEP coordinator for the common hippopotamus / Olomouc Zoo, Czechia

I perform research on hippos in captive environment, focusing on topics like suckling behaviour or sex ratio. In addition, I am keeper of the European studbook and coordinator of European breeding programme for common hippopotamus aiming to keep population viable and diverse. 

Rebecca Lewison 

Co-Chair/ Professor, San Diego State University, United States

My area of research focuses on common hippo foraging behavior and population dynamics in response to changing environmental conditions. I have a particular interest in hippo telemetry. My current efforts focus on supporting collaborative and inter-institutional initiatives on hippos as well as compiling country-level data for Red List assessments.


Executive Director of Congo Basin Conservation Society / CBCS-Network

Main interest and activity in hippos: my interest is related to the community-based protection and conservation of common hippopotamus of Lake Tanganyika and the Ruzizi River a transboundary wetland between DRC, Rwanda and Burundi where we are developing community-based strategies for species protection.  

Elie Bogui

Research Associate, Centre Suisse de Recherches Scientifiques in Côte d'Ivoire/Lecturer, University of Man, Côte d'Ivoire

My interest is related to scientific research and the involvement of local communities (environmental education) in the conservation of the pygmy hippopotamus in Côte d'Ivoire. Our main work is carried out in the Taï National Park where we have the largest number of pygmy hippopotamus individuals.

(i) Population dynamics of the hippo, which is important in addressing competing demands between various user groups, thus the hunting community on one hand and photographic tourism on the other. (ii) Hippo pasture (grazing areas) as this is critical in ensuring the long-term survival of the population and is an important tool in securing the critical components of the hippo habitats as anthropogenetic activities are the major factors responsible for loss of hippo habitat. (ii) Law enforcement, as well as compliance with national and international legislative frame works such as the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES).

Gabriella Flacke, DVM, MVSc, PhD

Pygmy Hippo SSP Veterinary Advisor/Associate Veterinarian, Zoo Miami

I am primarily involved with conservation and research with pygmy hippos but am interested in both hippo species. My PhD research focused on the pygmy hippo; I conducted field surveys in the Taï National Park in Côte d'Ivoire and also investigated ways to optimize health, reproduction and well-being under managed care. Together with several collaborators, I am trying to continue to support conservation and research efforts for this species throughout its native habitat, as so little is known about its basic ecology and biology.

Beatrice Steck

Global studbook keeper and EEP coordinator for the pygmy hippopotamus/Basel Zoo, Switzerland

My aim is to monitor the demographic and genetic development of the captive population of the pygmy hippopotamus worldwide in the global studbook for this species. In addition, I am responsible for the European breeding programme for this species with the objective of maintaining a healthy and viable population in European zoos. In addition, I am interested to inform the zoos holding this species about current conservation and research topics relating to pygmy hippos.

Thierry Aebischer

Head of Conservation and Biodiversity/Chinko Conservation Area/African Parks Central African Republic 

I'm interested in complex, species-rich ecosystems and their resilient functioning as well as ecological and evolutionary processes and their long-term conservation and restoration at large-scale. Currently I work in Eastern CAR in an area drained by the Chinko River, one of the most pristine tropical savanna rivers on earth that has high potential to harbour a large prospering common hippopotamus population. As one of the last grass-feeding megaherbivores they play a fundamental role in this freshwater system of Central Africa.

My work focuses on the management of natural resources and the conservation of large mammals, especially primates and pygmy hippos. This work makes the link between ecology, economy and culture for the empowerment of rural communities. In my approach, research feeds actions and vice-versa.

Ollo Théophille Dibloni


My research on hippos involves investigation of their habitat and their conservation in West Africa, and in Burkina Faso in particular as many populations are facing the problem of fragmentation there. Therefore, my aim is to summarise the status of all common hippo populations in at least eight West African countries. In addition, I deal with human-hippo conflict and the solutions how to mitigate it.

Deo has been working on Hippopotamus since 2009 during his MSc. Currently working with ICCN to protect hippos in the Luama Landscape (DRC). In the meantime, he works for the Wildlife Conservation Society in DRC. 

Chris Ransom

Durrell Wildlife Conservation Trust

I have been involved in conservation across Africa for almost 20 years and spent several years working in and involved with projects in West Africa with a focus on pygmy hippos. As part of this work I led, in 2010, on the first Conservation Strategy for pygmy hippos and have been involved with the Specialist Group since that time. 

Douglas J McCauley

Professor, University of California Santa Barbara

My research on the common hippopotamus is centered on understanding how hippos shape both aquatic and terrestrial ecosystem processes. Our group has a particular interest in the intersections between hippo spatial ecology and ecosystem ecology. With colleagues in Tanzania, we conducted the first successful study to track wild hippos using GPS technology.
