Marya Lieberman's Biography

Marya Lieberman, Professor, University of Notre Dame

Dr. Marya Lieberman is a surface and analytical chemist with over 60 peer-reviewed papers in the area of molecular electronics, DNA nanostructures, and low-tech analytical methods. She studied chemistry at MIT, obtained her doctorate in inorganic chemistry at the University of Washington, Seattle, and was a postdoc at the California Institute of Technology. Her current research focuses on paper millifluidic devices for chemical analysis in low-resource settings. These robust, inexpensive, and easy-to-use test cards help people solve problems outside the laboratory. Applications include detection of falsified and substandard medicines, monitoring nutritional supplement quality and population nutrition status, presumptive identification of illicit drugs, and evaluation of toxins in the environment.

Serious problems with the quality of both human and animal medications have been found in most of the developing world.  Although there is general agreement that removing low quality pharmaceuticals from the supply chain would be a good idea, there is no global program in place to monitor the quality of pharmaceuticals.  Existing analytical methods for pharmaceuticals lack the combination of low cost, reliability, rapid turn-around, and scalability needed in low-resource settings.  My research group has been trying to crack this problem by developing paper test cards to assay pharmaceutical dosage forms.  The prototype test card incorporates a library of chemical tests that generates a chemical profile of active ingredients and excipients present in a pharmaceutical.  We are now using the test cards at a project site in Kenya where we are attempting to find fake drugs using a random sampling process across 350 pharmacies in Western Kenya.  In this talk, I will demo the test card, show how it performs with different types of substandard and falsified drugs, and discuss the manufacturing and image processing challenges of scaling up the test cards.
