2011 REU Students

Garrett Vanhoy

Garrett VanhoyGarrett Vanhoy is a senior from the University of Arizona, returning to the Virginia Tech REU program for a second time. He is a double major in mathematics and electrical engineering. Last year, he came to the REU program at Tech because he had done research in mathematics but none in electrical engineering. Since there were fewer opportunities at his school for that research, one of his math professors recommended the REU program.

Outside of school, Garrett enjoys sports such as paintball, snowboarding, and almost anything that involves competition. He played travel and school baseball for eleven years. He also enjoys mathematics, because of the problem-solving involved. “I can really get lost in solving problems,” he says, “and will think for hours about them.”

In his senior year of high school, Garrett taught himself the whole curriculum of physics: electricity and magnetism, because no formal course was taught at the school. He then got a 5 on the AP test. He also taught himself C++ and Python by reading books and looking at source code.

After graduating college, he looks to attend graduate school—possibly at Virginia Tech, but is not sure yet—and eventually wants to teach.

Since he also is considering attending graduate school at Virginia Tech, he thought the program would be a good way to get to know more about the research going on in his field, and also to get to know the researchers.

Mohit Iyyer

Mohit IyyerMohit Iyyer is from Burke, Virginia and attends Washington University in St. Louis. He is a senior, majoring in computer science. At school, he is working on developing a medical diagnosis system with one of his professors to determine if a particular patient will experience clinical deterioration and require a move to the ICU based on around three hundred medical parameters such as blood pressure and shock index. The system creates a model by “learning” from existing patient data and uses that model to predict the condition of future patients.

Because of his work at school, Mohit wanted to increase his knowledge of learning algorithms. When he saw one of the suggested projects on the Virginia Tech REU web page involved signal classification, an area of research in which machine learning can play a major role, he thought it could be very helpful. Also, the communications aspect of the program was something he had never done before, so he wanted to apply his computer science study to an area which he knew little about.

Mohit hopes to attend graduate school and study computer science, and would potentially like to teach later on. In his spare time, he enjoys basketball, writing, and reading.
