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.

A. S. Chandrakala, Graduate Researcher


A. S. Chandrakala earned a Bachelor of Science in Biochemistry (University of Madras – India, 1994), and holds two master’s degrees in Clinical Biochemistry (MSc, University of Madras – India, 1996; MPhil, Bharathidasan University – India, 2006), along with professional certification in Bioinformatics (Gujarat University – India, 2004). For several years, Chandrakala was a Senior Lecturer in Biochemistry at various colleges in India. For the past three years, at the University of New Hampshire, Chandrakala pursued independent investigations in the areas of plant tissue culture and biotechnology (Minocha lab 2016-2019) and protein expression and purification (Varga lab 2018-2019). She also worked as a research technician in the Minocha lab (2016-2019) and at the USDA Forest Service (2017-2018), in addition to teach Cell and Molecular Biology at Concord Community College (2018). Chandrakala joined the Lima lab in 2019 as a graduate student to pursue a doctoral degree. Her research project involves the study of phytochemicals, and their roles in grapevine health and nutritional quality of grapes.

Madeline Young, Undergraduate Researcher



Madeline Young is an undergraduate student in the Biology B.S. program. At the Lima lab, she is working with soybeans evaluating factors related to iron deficiency chlorosis and iron bioavailability. Previously, she has assisted research on Ceratina calcarata (Rehan lab 2018). Young plans to continue her education through Graduate school to pursue a M.S and PhD in Biomedical Engineering.

Molly Hanlon, Undergraduate Researcher



Molly Hanlon is a senior undergraduate Biomedical Science: Medical and Veterinary Science major. She is on the pre-Physicians Assistant track and plans to take a year off before Physicians Assistant school. Molly hopes to specialize in OB/GYN someday due to her interest in the female reproductive system. At the Lima Lab, Molly is working on the biochemical analysis of grapes as it relates to their nutritional quality important for human health.
