Phenotypic Traits of Switchgrass Cultivars Associated with Increases in Biomass Yield
Published:
In this talk I explored how C4 bioenergy crop switchgrass has phenotypic traits associated with increases in biomass yield of improved and/or registered switchgrass genotypes. I examined specific leaf area, tiller number, tiller diameter, tiller mass, and height in a common garden experiment.
The Role of Carbonic Anhydrase in C4 Photosynthesis and Mesophyll Conductance
Published:
Presentation on how the first enzyme involved in concentrating CO2 in C4 photosynthesis reacts to temperature. When carbonic anhydrase is low it may not be able to keep pace with the second enzyme in the pathway, PEPC.

Teaching English in China
Undergraduate Oral English, East China Institute of Technology; Inner Mongolia Normal University; and Teachall Consulting, 2009
I taught English as Second Language (ESL) in China for three years at the college/adult level. And while I was there I took Chinese language courses at Beijing Radio and Television University in Beijing. Most of my work was engaging students in the practice of conversational english. The following are some photographs and summaries of the Universities and venues I taught at.
BIO 106: Organismal Biology
Undergraduate Lecture and Lab Course, Washington State University, School of Biological Sciences Department, 2020
I TA for BIO106 and I wish that I had access to such a great course back when I was an undergraduate. The class teaches the foundational concepts of biology that enable generalizable understanding of life at micro, macro, and global scales. As a TA, I teach discovery-based learning in small(er) sections where students independently run experiments. My personal teaching style comes through in our class intro’s and the quiz material that I write. The main tenets of my teaching philosophy are:
