Dr. Tzouanas' research interests are in the following areas: 
   1) process design, modeling, and simulation 
   2) process control
   3) renewable energy systems.

The objective of his research is to not only invent new knowledge but also convert the "feasible" into "practical". The result is control systems that help optimize process operation (i.e. maximum return on investment) subject to operational excellence (i.e. safety, environmental, reliability, quality) constraints. Process examples are drawn from different industrial sectors such as chemicals, refining, bio-systems, and renewable energy systems.

Dr. Tzouanas' research efforts provide high impact learning experiences to many UHD undergraduate students by involving them in research early on in their studies.

Dr. Tzouanas is the recipient of the following awards:

  • Halliburton Professorship, 2016.
  • Halliburton Professorship, 2014.
  • Lyondell Corporate Award for Efficiency, 2006.
  • Amoco Technical Award, 1998.
