Service: In charge of the Dewel Microscopy Facility – a multi-user core facility in the College of Arts & Sciences (CAS). For more information about the facility, please visit http://www.casmifa.appstate.edu/
Teaching: Independent Study of Microscopy (Bio 5500 for graduate students and Bio 3500 for undergraduate students) that covers optical microscopy including laser scanning confocal microscopy and electron microscopy (SEM and TEM). (Previous teachings include Botany, Plant Physiology, and Traditional Chinese Medicines.)
Research: Plant root development – Roots play a critical role in growth and yield of vascular plants, such as crops and medicinal plants. Individual root development occurs primarily at the apical meristem while root system formation coordinates with shoot development and the organism as a whole. Research aiming to further our understanding of root development and root system formation has been conducted in the lab using the model species Ceratopteris richardii (triangle waterfern), Arabidopsis, and maize (corn, Zea mays).
Co-PI on AppalSEED Academy that is funded by Burroughs Welcome Fund.
