My name is Kehinde Faronbi. I am a student at Alverno college. My Major is Mathematics and my minors are Computer Information Technology and Elective studies. My research title is "Calculating the Effect of Competition on Survivability on an Ecosystem Using a Weighted (1,2)-step Competition Graph Model" with Andria and Dr. Factor. I will be focusing my research on Lake Tanganyika Ecosystem.<br />
