I have been working as a chemical engineering consultant for over. nine years. I hold a PhD in chemical engineering and am PE licensed in Ohio and Colorado. As a consultant I have over seen a variety of chemical process problems, primarily in the thermal engineerign arena. I have also been involved in a six year effort to develop and model a bioartificial pancreas. I have utilized CFD an a variety of other process flow sheet development tools to solve more traditional chemical process problems.
