Alpha Baldé, PhD

After my university studies, I got involved in the field of herpetology. I live in a country where the herpetofauna is still poorly understood and some new species have only been discovered very recently. Serious threats continue to weigh on the amphibians and reptiles of Guinea, such as deforestation, bush fires, and mining. I hold a Master's degree in herpetology and recently finished my PhD on the venomous snakes of Guinea.

Cellou Baldé, PhD

Dr. Cellou Baldé is a herpetologist and snakebite expert with the Institute Research Biology Appliquee De Guinée. Dr. Baldé established a snakebite clinic in Kindia, Guinea where he treats more than 500 snakebite patients annually. Over 30% of these patients are high acuity envenomations due to neurotoxic elapids, a disproportionately high incidence in comparison to the rest of the continent. Cellou has extensive experience in the management of these patients and has joined forces with ASF to develop innovative strategies to reduce the death and disability caused by snakebite in Guinea.
