Efficient Control of Tunnel Freezers
Food products need to be rapidly cooled and frozen using freezer tunnels but with minimal energy wastage. The research considers striking a balance between energy conservation, freezer performance, and quality, given the food products are stochastic in terms of size and thermal loads. Using a stochastic dynamic programming model, total system-wide cost is minimized by controlling cryogen generation optimally. Industrial Partner: Air Liquide.

Energy Conservation in Wireless Sensor Networks
Efficient information sharing in multi-hop wireless networks is needed to optimize energy usage while not compromising performance. The research is a combination of multiple topics: (a) strategies to leverage network coding opportunities; (b) maintenance policies for underwater sensors; (c) techniques based on epidemic spread models for information dissemination.
