Over the last century of plant research, whether 植物相互作用 will be competitive, 中性, or facilitative has remained elusive.  This enigma may persist because most investigations have failed to consider the role of ubiquitous common mycorrhizal networks formed by symbiotic arbuscular mycorrhizal fungi.  

Arbuscular mycorrhizal fungi are symbiotic, 根栖真菌, that associate with the majority of plants in the world today. 因此, arbuscular mycorrhizal fungi can interconnect plants when hyphae from one root system forage for mineral nutrients throughout the soil, then encounter and colonize the roots of another plant, forming a common mycorrhizal network.

To understand how these fungi contribute to plants’ competitive abilities and consequent species dominance, my research investigates the influence of common mycorrhizal networks on plant mineral nutrition, 植物相互作用, 营养运动.  To understand how being interconnected to neighbors affects plant individuals, my research incorporates the use of various cutting-edge tools such as stable isotopes, and in the future I plan to utilize 在体外 root organ cultures, and Next Generation Sequencing

A second research interest of mine is in the science of teaching.  I am interested in the role of course-based research experiences in student achievement, retention within STEM (Science, 技术, 工程, 和数学)领域, and interest in pursuing extracurricular research experiences.   I am particularly interested in how course-based research experiences may influence students from underrepresented minority or first-generation backgrounds.
