Graduate student Piyush Dak from Professor Alam's group has recently explained the extraordinary high sensitivity of MoS2-based cancer biosensors as a consequence of the insulator-free detection enabled by hydrophobicity of the two dimensional semiconductors. The theoretical work promises early detection of cancer biomarkers. The results, along with the experimental demonstration by colleagues from  Kyung Hee University in Korea, were recently published in Nature Scientific Reports.  Piyush Dak's  research focuses on building a simulation framework and providing design guidelines for portable, wearable and implantable electronic biosensors. In the past , he has worked on modeling and simulation of charge trap flash memories .
