**Undergraduate Research Supervised**- Michael Lin (Summer 2014)

He studied a four species evolutionary game that had previously been studied by Basanta, Scott, Rockne, Sanson and Anderson. He made good progress at mapping out the phase diagram, showing that some of the results in the paper were not correct. - Luxi Wei (Fall 2013- Spring 2014)

In the Fall of 2013, she read papers on modeling credit risk in preparation for writing a senior thesis, which she completed in the Spring of 2014. She graduated with distinction at the end of that semester. - Anne Talkington (Summer 2013 - Summer 2016)

In the summer of 2013 she studied models for cancer growth as part of the math biology RTG. During the 2013-2014 academic year we developed the research into a paper that has recently been accepted by the Bulletin of Mathematical Biology. She will graduate at the end of the Fall 2015 term but will stay around to do research with me in the Spring. - Kaveh Danesh (2011-2013)

In a collaboration with Evan Myers and Laura Havrilesky in the Duke Medical school, we worked on predicting the window of opportunity for ovarian cancer screening, resulting in a paper in J. Theor. Biol. Kaveh was a Fulbright Scholar studying cancer villages in China during 2013-2014, and is now in the Applied Math program. Since he is a student trustee I see him three times a year when they meet. - Yifei Chen (Summer 2011)

Participant in math bio RTG. His simulations were useful in improving a reuslt in my paper on population genetics of exponentially growing populations. - Aashiq Dheeraj (2012-2013, Spring 2014)

Math Bio RTG participant. Studied spatial versions of evolutionary game models in cancer. In the Spring of 2014 he wrote up this work as an honors thesis and graduated with distinction. - Conrad de Peuter (Spring 2013)

His honors thesis was "Using Markov renewal processes to model basketball games." He went to work at ESPN after graduation but later learned that a job that involve watching lots of basketball was not the dream it sounded like. He is now applying to graduate school in statistics. - Willie Zheng (Spring 2013)

Supervised his honors thesis in Math. Upon graduation he enrolled in an MD/PhD program at Washington U. St. Louis.
