During my career at three universities, I have taught numerous graduate and undergraduate courses, including:
- Introduction to Soil Science
- Soil Fertility and Plant Nutrition
- Soil-Plant Relationships
- Nutrient Dynamics in Soils
- Graduate Seminar
- Senior Seminar
- Nutrient Management in Soils.
I am an agronomist and soil scientist and have worked with vegetable crops, trees, and agronomic crops such as cotton, grains, and alfalfa. Recently my research has focused on conservation agriculture practices and adoption in smallholder farming systems of developing countries.
Role of Graduate Students
One of the best things about being a faculty member is working with graduate students. I have served as advisor for more than 20 graduate students. As a graduate mentor, I believe in “paying it forward”. I had two very different mentors in graduate school, and both contributed tremendously to my maturation as a scientist. Now, I try to do that for others.
One must learn to adapt in research. It’s important to look for opportunities, and sometimes you don’t end up where you expected. And that can be exciting.
