Hi! My name is David and I recently graduated from Columbia with my Masters in Public Health. I am very passionate about science and I hope to dedicate my career to improving the environment and people's health. I've always enjoyed teaching whether I'm with my students as a TA or just with my friends helping them with assignments. I think understanding difficult concepts can be stressful at times so I hope to make learning enjoyable by simplifying hard questions and boosting my students' confidence.
