Institute of Technology(MIT), my group focuses on advanced electronic devices based on new semiconductors, especially nitrides and graphene. These semiconductors are, probably, the most complete semiconductor family ever, and we are currently using them in 4 different applications:

High frequency electronics (>300 GHz)
High voltage electronics (600 V – 10 kV) for power conversion
Digital electronics in a post-Si scenario
New concepts for biosensors and energy harvesting devices
