Marta R. M. Lima, Assistant Professor


I have been studying plant responses to biotic and abiotic stresses using an interdisciplinary approach with an emphasis on metabolomics. Specifically, I have been characterizing molecular and biochemical mechanisms of plant-pathogen interactions, plant responses to combined biotic and abiotic stresses, as well as processes involved in plant response to iron deficiency and the impact of legume iron composition on human nutrition. One major aim of my work is to elucidate changes induced by stress on overall plant metabolic pathways and translate that knowledge into practical applications. Recently, I started using metabolomics to study the relationship between nutrition and health using the neonate pig as a model. My current research focuses on the impact of external factors (biotic/abiotic stresses or management practices) on plant physiology and biochemistry, and addresses issues of crop productivity, plant health and nutrient/phytochemical composition of fresh fruit and legume species. The ultimate goal of my research program is to improve agricultural sustainability, crop quality and yield, food security, and human health and nutrition.

Jessica Hodgkins, Undergraduate Researcher


Jessica Hodgkins is an undergraduate student in the Biomedical: Medical Microbiology B.S. program.  She has assisted research on antifreeze proteins (Varga lab 2017) and is currently assisting research on the virulence factors of Serratia marcescens (Tisa lab 2018).  She is also supporting the launch of the research program in the Lima lab (2018). Hodgkins plans to continue her education, enter the biotechnology industry, and eventually become involved with government research policy and management.




Plant Physiology and Metabolomics

A Graduate Assistantship is available in the Lima Lab in the Department of Agriculture, Nutrition and Food Systems at the University of New Hampshire, starting Summer or Fall 2019.

Candidates should have a background in Biology, Biochemistry, Agricultural Sciences or related field, and a strong interest in metabolomics and interdisciplinary research. Experience working with plants, and basic laboratory, research and writing skills are preferred. Interested applicants should send a letter of interest along with a copy of their curriculum vitae and contact information for three professional references to Dr. Marta Lima, via email (
