Liu and Peng are now two of 300 semifinalists who will now have the chance to advance to the finals, where 40 students will be invited to Washington D.C. in March to compete for the top award of $100,000.
Liu was named as a semifinalist for her work focusing on the defibrillation of the heart by light and the simulation of optogenetics in cardiac tissue.
Peng has been nominated for her work on a cellular automation model for critical dynamics in neuronal networks. The same project helped her take home $50,000 last month after finishing second in a 2012 Siemens competition in math, science and technology.
