Area of Focus
Plant Breeding, Genetics, and Molecular Physiology
Acidic or alkaline soils occur on most of the earth, and these conditions limit mineral nutrient availability to plants. Plant-based foods are a primary source of human nutrition that is typically at suboptimal mineral density. My research focus is in plant nutritional physiology and molecular genetics, and seeks to gain a mechanistic understanding of how plants respond to mineral nutrient limitation, the physiological processes that move minerals from the soil, through the plant, and into the edible portions, and to determine which genes or gene products carry out or regulate these processes.
Research areas in the lab include regulation of plant responses to iron deficiency stress, biofortification of crops by increasing mineral density in edible portions of plants, control of carotenoid accumulation and other quality traits in melon (Cucumis melo) fruit, and nutrient use efficiency. Our approach combines traditional plant physiology with molecular biology, genomics, genetics, and use of natural variation.
Major Project Activities
- Regulation of mineral deficiency stress responses.
- Mineral partitioning dynamics and regulation of gene activity over the plant life cycle.
- QTL mapping of biofortification related traits.
- Expression profiling of genes involved in mineral remobilization during leaf senescence and translocation to seeds during seed fill.
I currently teach Scientific Writing and Communication (AGRO/HORT 403/803). This course serves as a capstone for the Plant Biology major and the Horticulture (Research Option) major, and is an ACE 10 certified course. The course is offered every spring. For two years, I have participated in the Peer Review of Teaching Program, and produced course portfolios about measuring student learning in the course.
