Introduction
I study the relationship between changes in plant physiology and ecology, and insect and arthropod species diversity. I also look for nutritional and allelochemical changes in plants as mechanisms for changes in insect/arthropod diversity. Aside from that, I research pedagogical methods that can improve student engagement and learning in large courses.

Climate change is predicted to increase the frequency of drought conditions and alter plant–insect interactions. Despite over 530 studies on the effects of water‐deficit stress on plant–insect interactions, we still cannot accurately predict plant–insect interactions under drought conditions. Most studies have focused on how insect herbivores respo...
This is the sequencing and annotation of a novel Microbacterium foliorum phage.
This is the GenBank publication of the sequencing and annotation of Gordonia phage Avazak.
This is the GenBank publication of the sequencing and annotation of the Arthrobacter phage LouisXIV.
The USDA stated that 21.2% of households in Arkansas experienced food insecurity in 2013, compared to 14.3% nationally. Johnson County in Arkansas was also designated as a “food desert”, in which households lack access to fresh, healthy, and affordable food. Community gardening in Johnson County is an attempt to mitigate this food shortage and a so...
In our mixed methods study, we used the Professional Learning Communities framework as a support for the analysis of teaching strategies across academic disciplines. This study was conducted by colleagues from the Biology, Psychology, and Teacher Education departments who collaborated to explore the impact of the flipped classroom method on student...

Bacteriophage discovery, the journey, and applications to medicinal research.
Predicting interactions between drought and plant–insect interactions has been a challenge. Currently, we are unable to accurately predict herbivore abundance on stressed plants despite over 500 publications and half a dozen formal hypotheses. With drought predicted to increase in severity with climate change, determining herbivore abundance on str...
Social living poses challenges for individual fitness because of the increased risk of disease transmission among conspecifics. Despite this challenge, sociality is an evolutionarily successful lifestyle, occurring in the most abundant and diverse group of organisms on earth-the social insects. Two contrasting hypotheses predict the evolutionary co...
Drought stress is predicted to become more prevalent in the future and affect plant-insect interactions. During drought stress, plants may increase concentrations of nutrients (amino acids, carbohydrates) in order to alleviate the effects of stress, but these nutrients may also increase herbivore abundance on stressed plants. The effects of stress...

There are many hypotheses that explain the interactions between plants and insect herbivores. The plant stress hypothesis (PSH) states that water stressed plants will raise herbivore performance due to increases in N containing compounds (White 1969). The plant vigor hypothesis (PVH) states that plants that are growing...
Modified environmental conditions are driving phenological changes in ecosystems around the world. Many plants have already responded to warmer temperatures by flowering earlier and sustaining longer periods of growth. Changes in other environmental factors, like precipitation and atmospheric nitrogen (N) deposition, may also influence phenology bu...
Plant physiology is altered dramatically when water stressed. Nitrogen (N) availability, digestible carbohydrates, and nutrients all change when plants are water limited and changes in the availability of these resources may benefit insect herbivores. Currently, we are unable to accurately predict herbivore response to host water-deficit stress. Th...

Plant physiology is altered dramatically when water stressed. Nitrogen (N) availability, digestible carbohydrates, and nutrients all change when plants are water limited and changes in the availability of these resources may benefit insect herbivores. However, the degree and duration of these benefits depends upon the severity of the experimental s...
