Dr Filipa VM Silva

BE, ME, PhD

Biography

Filipa Silva completed a five year Food Engineering Bachelor degree in the Superior School of Biotechnology, Catholic University of Portugal, and a two year Master of Engineering at the University of Florida, USA, focusing Postharvest Technology and Distribution of Perishable Fruits and Vegetables.In 2000 she concluded a PhD in Biotechnology in the field of Food Science and Engineering.  She taught the following courses in tertiary education institutions between 1995 and 2006: Agricultural Products Technology, Postharvest Technology, Introduction to Bioprocesses, Thermodynamics, Process Engineering and Statistics.

From 2003 to 2009 she investigated the biological activity of new plant extracts, carbohydrates and natural products at the University of Lisbon and the Polytechnic School of Santarem.

Her research activity and interests are in Food Process Engineering, in particular studying the effects of new food preservation technologies such as high pressure processing (HPP), on food safety and shelf-life, and the design of proper pasteurisation processes. Her expertise in microbiology and enzymes are helpful for studying the effect of emerging food preservation technologies on food spoilage microbes/enzymes. The production of plant extracts and the determination of their biological activity such as antibacterial, antifungal and insecticidal activities, is another area of research.
