In a recent blog post, my colleague Dr. Yinjie Qiu posted his article entitled “How did I become a turfgrass guy?” in response to finalizing his graduate degree. As I too prepare to leave, his message provoked personal reflection on how my own experience in turf science was also not run of the mill. Many turfgrass scientists develop an interest in the science and biology of our nation’s #1 irrigated crop by spending their early years mowing golf course greens and fertilizing sports fields. I, however, grew up on a hobby small farm where I was far more interested in forage grasses than in turfgrasses. Although I did mow the lawn on occasion, producing vegetables and raising chickens, goats, and beef cattle for the annual county fair kept me heavily engaged in 4-H and FFA throughout my childhood and adolescence. As my high school years waned and I looked forward to college, I decided to pursue a degree in crops and soil science. After gaining some work experience on a forage research farm, I saw an agricultural path as a fulfilling choice.

As I made my way through a four-year degree at UW-River Falls, I must admit turfgrass science was not on my academic radar; courses such as corn and soybean production, forages, and even interior plantscapes took precedence. In fact, when it came time to take my education beyond a B.Sc., I really had no plans for my future beyond gaining entrance to a school that had a plant breeding program. So, what was it that facilitated my not-so-usual entrance into the ranks of turfgrass scientists? Well, as far as I can recollect, it was a mixture of happenstance, luck, and general curiosity of grass biology. My second on-campus interview for graduate school was an informal and impromptu visit with Dr. Eric Watkins. The project he proposed focused on seed production systems for the turf market and on-farm research in northwest MN, which sparked my interest. During a walk though some Kentucky bluegrass plots he asked the question, “Do you know what apomixis is?” and I rapidly and eagerly tried to articulate the bits of knowledge I had retained from my forage classes at UWRF (Kentucky bluegrass also being a common forage species). My excitement for the project, and a fairly accurate response to an inquiry on the reproductive strategy of a common cool-season grass, helped launch my six-year graduate career.

During my master’s program (2013-2016) at the University of Minnesota I researched methods to increase the longevity of perennial ryegrass seed production systems near Roseau, MN. I also investigated the impact of a widespread species of fungal endophyte on the freezing tolerance of perennial ryegrass. Because of my focus engaged me in agricultural systems of a horticultural amenity species, I had the opportunity to engage in other research on forage grasses and legume cover crops. The dual working environment kept things interesting and I stayed at the UMN to earn my Ph.D. (2016-19). I continued my focus on perennial ryegrass and seed production systems; however I transitioned the bulk of my work to breeding and genetics. I worked to improve our ability to simultaneously select for turfgrass quality and seed yield, examined the potential of fungal endophyte mediated disease resistance, and worked to backcross herbicide tolerance into elite germplasm. During my Ph.D. and my short stint as a postdoc (2019-20), I also gained sufficient computer coding knowledge to develop an open source image analysis system that quantifies some diseases on grass tissue and I also gained fulfillment in teaching tutorials on applied statistical analysis.

Looking to the future I hope to stay involved in the turfgrass industry with a focus on seed production which I would like to couple with forage seed production as well. In May 2020, I am moving to eastern Washington State to start work on a short-term project on lentil pathology and forage seed crops in collaboration with scientists at the USDA-ARS. Luckily, like my entrance into turfgrass science, this move seems to have placed me in an ideal region to continue my research and support the turfgrass seed industry, an industry that has provided me many fulfilling research opportunities, including grower engagement, and cross disciplinary collaborations.
