Biography

Marianna Foldvari is a Professor and served as the Associate Director for research and graduate studies in the past 4 years at the University of Waterloo’s School of Pharmacy. Foldvari’s expertise is in pharmaceutics, dosage form and drug delivery system design and pharmaceutical nanotechnology. She has over 20 years of experience as an academic researcher and in research and development in the pharmaceutical industry through technology transfer activities.

Foldvari is an internationally recognized expert in nanomedicine. Her research program focuses on the development of intelligent and non-invasive drug delivery systems design for protein drugs, gene therapy and pharmaceutical development of nano-enabled products.

Foldvari developed Biphasix™, a needle-free drug delivery system for dermal delivery of drugs. Important characteristics of the delivery systems are improved drug encapsulation and drug permeation through the skin.

She is Associate Editor of Nanomedicine: Nanotechnology, Biology and Medicine, Editorial Board Member and Hot Topic Editor for Current Drug Delivery, the Journal of Nanomedicine and Biotherapeutic Discovery, the Journal of Bionanoscience and the International Journal of Pharmaceutical Compounding.

She is the founding Director of the American Society for Nanomedicine (ASNM) and the International Society of Nanomedicine (ISNM). She served as board member for Genome Prairie and was a member of the advisory committee to the Prime Minister on Science and Technology and was a Founder of the Canadian Society of Pharmaceutical Sciences (CSPS). She has received the Young Women's Christian Association (YWCA) Women of Distinction Award and the Sabex Award of Innovation.

Foldvari has authored more than 100 papers and 70 conference presentations and is the inventor on 15 patents. She is a frequently invited speaker at national and international conferences on gene and protein delivery systems and nanomedicine development and applications. She founded two spin-off companies that focus on nanomedicine product development to commercialize technologies that she and her research team have developed.

Research

Non-invasive technologies

The main objectives of Dr Foldvari’s research are to develop new, non-invasive technologies for the delivery and ultra-specific targeting of therapeutic agents into the body and to diseased tissues and to investigate the fundamental properties of these delivery technologies and the cells they target.

Protein delivery system for transdermal delivery

Professor Foldvari created a spin-off company called PharmaDerm to commercialize the Biphasix™ technology, which was later purchased by Helix BioPharma. Biphasic vesicles are complex, multicompartmental systems, in which lipid bilayers entrap a stabilized submicron emulsion.

DNA delivery system for cutaneous gene therapy

Skin is the largest and most accessible organ of the body and is an ideal target for gene therapy. Professor Foldvari’s group is using keratinocytes transfected topically by non-viral delivery systems in the skin as "in situ bioreactors" to produce the therapeutic protein for local and systemic treatment. Professor Foldvari’s gemini surfactant-based nanoparticle delivery platform had led to increased gene expression in the skin. Professor Foldvari formed a company called Forte Pharma Inc. to commercialize this technology.
