Dr, Christian Tiambo decides to become vulnerable on the show and tells more about the struggles he had and the triumphs of his journey in science.Scientist. Livestock Genetics/Genomics: Precision Breeding and Reproductive Technologies, Biobanking management, Access & Benefits Sharing Officer CTLGH/ILRIThe Vulnerable Scientist is a Kenyan-based podcast that focuses on scientists' stories about their daily lives, work, and how they got to where they are. I am your host Sarah Nyakeri, a scientist, informal science communicator and a hiker. I am a multidisciplinary individual that does digital marketing and website design during my free time.The main questions asked that scientists are expected to answer vulnerable are: How are you, Introduce yourself, how did you become a scientist, What are the highs and lows you have experienced in your science career, tell the listeners about your hobbies, what question would you like to answer that has not been asked and how do you feel after having this conversation.Why did I start this podcast? You might ask. When doing my MSc project, my experiments started to fail at a certain period and it was very frustrating. I thought, If I finally get a new vaccine target for CBPP in cows, it would be all smiles but no one will ever know what I went through. I also wondered how many scientists were going through the same rough patch but did not openly talk about it?One day when I had just had a rough day, I talked into a mic about my day and I felt better. That was the first episode. At first, I thought it would just be journalling but after some fellow scientists heard it, they wanted to be Vulnerable too. Since then I have brought scientists from different fields to tell their stories of the highs and lows they have experienced with honesty and authenticity being the lead of our informal and long conversations.I enjoy asking questions since I am a naturally curious person. Feedback from the audience, including scientists and non-scientists, is the main motivation I message scientists or accept their request to be on the podcast, schedule an interview, edit audio, design the artwork, post it, and share it on social media platforms.
