Biography

Simioan Petrovan

Simioan Petrovan earned his MS degree in 1963 and PhD degree in 1974 in Pulp and Paper Technology from Technical University Iasi, Romania. He held the positions of Assistant to Professor at Pulp and Paper Department and Macromolecules Department until 1997, where he taught various courses in Pulp and Paper Technology, Polymer Processing, Chemical Engineering Fundamentals, Chemical Reactors, and Transport Phenomena and Unit Operations.

In 1997 he joined the Chemical Engineering Department at Louisiana State University, Baton Rouge as a Research Associate Professor. From 1999, Petrovan was a Research Associate Professor at Chemical and Biomolecular Engineering Department, the University of Tennessee, Knoxville.

He has authored or co-authored 90 technical papers, over 110 presentations at national and international conferences, 1 book, and chapters in 3 books. Among the most recent research fields of interest are rheological characterization of cellulose solutions in environmentally friendly solvents such as N-methyl-morpholine oxide monohydrate and ionic liquid 1-butyl-3-methylimidazolium chloride, carbon fiber precursors from cellulose/ionic liquids solutions, and lignin carbon fiber precursors.
