Feisal Khoushab

Feisal has earned degrees in computer science, bioengineering, natural resources, biology, and is currently working towards his education degree. He has two patents, has published articles in international journals, andhas presented at international conferences. While doing scientific research, Feisal found that he was interested in teaching and so shifted his focus to education. While studying, he also realized how the different sciences are all connected to each other, so in the classroom he tries to make as many connections as possible between the different fields. In this way, students develop an understanding of the inter-relatedness of things, and are able to develop a sense of the ‘bigger picture’ of things.
