Summary of Expertise: Listed with other top experts in: 
In 30 years working with polyurethanes, Expert has developed numerous types of polyurethane elastomers, foams, adhesives, coatings, and other products with specific application requirements.

In the past several years, her work has extensively involved development of polyurethanes for medical applications. The materials for medical applications need to meet a rigorous set of standards. As an example these materials must be non-toxic and biocompatible. For long-term implantation the materials also need to be biostable, resisting in-vivo degradation. Furthermore, the materials need to meet the specified application function.

In the past 5 years, Expert developed 3 different polyurethanes for surgical applications: 1) 2-component structural bone cement adhesive, 2) load-bearing surface for joint implants, and 3) porous foams for as scaffolding platform for tissue in-growth.

These materials are in different stages of development, with some of these products already receiving the FDA and CE approvals.


polyurethane material

Over the past 30 years, Expert has developed and invented various polyurethane products that include rigid and flexible foams, elastomers, coatings, adhesives, sealants, etc. Her experiences in wide variety of polyurethanes often results in unique approach to product development. As an example, Expert was first to combine polyurethane foams with moisture-cured isocyanate resins to produce novel curable tapes used in medical immobilization and other applications.


The basic components in the synthesis of polyurethanes are isocyanates and polyols, which form urethane linkage. Under appropriate processing conditions, isocyanate may also form other linkages, such as urea, allophanate, biuret, isocyanurate, carbodiimide, uretdione, amide, imide, oxazolidone, etc. In applications requiring good heat and thermal stability, polyurethane linkages are often not suitable as they starts to dissociate (break) at 100-140° C. Therefore, for higher temperature applications other linkages may be preferred such as urea, oxazolidone, isocyanurate, imide, etc.

The formation of these bonds is controlled by the selection of appropriate catalysts, reaction temperature, and composition of the starting components, etc. Expert has completed several studies of the kinetics and catalysis of formation of heat resistant groups, including oxazolidone, isocyanurate, and imides. The study on model reaction systems was extended to development of various heat resistant isocyanate-based products, such as isocyanurate foams, polyoxazolidone composites and coatings, polyimide foams, etc.

Research Director


Coordinates and leads contract R&D efforts for development of wide range of polyurethane materials with tailored properties for biomedical, electronics, construction, automotive, space, chemical, and agricultural applications. Her expertises are in polyurethanes foams, elastomers, structural adhesives, immobilization casts, blocked-isocyanate heat activated products, clear polyurethane cast elastomers, and hydrophilic polyurethanes. In addition to application development, she is routinely involved in evaluation of new and novel raw materials for polyurethanes. She had also coordinated studies on the environmental stability of isocyanates.

1988 to 2001


University of Detroit Mercy


Polymer Institute


Senior Research Scientist and Adjunct Professor


Conducted fundamental research and application development projects with focus on polyurethanes. These research efforts were primarily contract research projects sponsored by private sector and governmental agencies. She also coordinated research work of visiting scientists from around the globe and graduate students working on graduate thesis. Her area of research covered kinetics and mechanism of isocyanate-based reactions, structure-property relationship in polyurethane elastomers and foams (both rigid and flexible), development of heat resistant polymer properties (oxazolidone, isocyanurate, polyimides), fuel resistant foams, medical products (immobilization cast, artificial joints, drug release platform), acrylate/polyurethane blends, etc.
