Ph.D., 1978, SUNY College of Environmental Science and Forestry; 1978-80, Postdoctoral Research Associate, Department of Chemistry, SUNY-Binghamton; 1980-81, Development Chemist, St. Regis Paper Company; 1981-98, Various research and technology management positions, Texaco R&D, Beacon, NY; Joined the ESF - Department of Chemistry in September 1998.

Dr. Stipanovic is a polymer chemist with interests in biobased, biodegradable materials and analytical technologies to support the wood-based biorefinery. He has taught FCH 552: “Polymer Science: Properties and Technology”, which deals primarily with polymer physical chemistry, characterization, and applications. His teaching experience also includes General Chemistry II (FCH 152) and General Chemistry Lab I and II (FCH 151,153).  Ongoing, externally funded research projects are summarized below:

1. The impact of solid-state structure and morphology of cellulose on the activity of recombinant cellulase enzymes (Yao Chen, M.S. 2005; Jessica Hatch, Ph.D. Candidate); Joint initiative with Cornell University and Dr. W. of ESF ( DOE supported).
2. NMR and TGA methods in the high throughput characterization of lignocellulosic biomass such as fast griwng willow species (Michelle Serapiglia, Ph.D. Candidate). 
3. Extraction of hemicellulose from biodelignified wood and the development of new applications for xylan hemicellulose as a renewable, biodegradable material (Collaboration with Drs. Amidon and Scott; PSE; USDA McIntire Stennis, Xerox Foundation support; Kunal Mishra, M.S. 2007).  
4. The production and characterization of thermoplastic, biodegradable, microbial polyesters using wood-based feedstocks such as xylose and levulinic acid (jointly with Dr. Nakas, EFB). Fabrication of polyester blends with cellulose and xylan derivatives.
5. The fabrication, characterization and release rate modeling of micron-sized controlled release polymer particles for insect pheromones (Patrick Hennessy, MS 2003; Co-PI: Dr. Fran Webster; Financial support from the USDA).
6. The use of cellulose particles in the development of electro- and magneto-rheological fluids and elastomers in stimuli responsive materials (Shengbin Zhang, Ph.D., May 2004; Financial support from Eastman Chemical Co. and the USDA).
7. Reducing the recalcitrance of cellulosic biomass for biofuels production using electron beams and microwaves, jointly with Dr. Mark Driscoll and industrial collaborators.
