Andre Unger, PEng

André Unger develops and applies numerical methods and algorithms to solve a wide variety of problems involving Earth Sciences and Geological Engineering

Professor Unger studies how municipalities can sustainably manage their water resources and infrastructure using a variety of tools, including groundwater and surface water modeling, and water infrastructure asset management tools.

Professor Unger also studies the financial and health risks associated with re-developing hazardous waste sites known as "brownfields" using alternative clean-up techniques.

Professor Unger also studies aspects of signal analysis and spectrogram inversion with specific application to speech recognition and synthesis.
