Hi everyone, ​My name is Selina, and I am a high school student at Mfantsiman Girls’ High School in Ghana. I am an aspiring surgeon and very passionate about using data to solve healthcare challenges in Africa. ​I have joined this challenge to learn more about how we track and fight infectious diseases. As a beginner in data science, I would appreciate any tips on which tools I should start learning (Python, Excel, or others) to be successful in this field. ​Looking forward to learning from you all! ​Best, Selina Nana Akua Nyavor
