​I’ve always loved science and problem solving. In college, while being drawn to literature, I found my passion working in a research laboratory. In graduate school my research focused on deciphering the signaling pathways of the phytohormone auxin during seedling development in Arabidopsis thaliana. An unexpected phenotype of an auxin signaling mutant introduced me to the world of circadian biology. I was instantly fascinated by this internal clock that tracks changes in daylength and coordinates plant growth with the external environment. Later, my interests shifted towards exploring the consequences of this internal timekeeping on plant fitness. Little did I realize at the time that studying the circadian clock meant sacrificing my own clock when performing essential multi-day time course experiments.

As an NSF National Plant Genomes Initiative Postdoctoral Fellow, I applied co-expression network analysis to integrate temporal changes in transcriptomic and physiological responses to drought in the crop Brassica rapa. This study revealed early temporal indicators of drought perception and the importance of time when assessing stress response. Over time, acquired RNA-sequencing datasets provided the basis for exploring the expansion of the circadian transcriptome in Brassica rapa and has led to a broader interest in exploring the role of the clock during crop domestication. Due to the extensive polyploidy inherent in crop genomes, we are more dependent on computational approaches and the need for broadening our collaborations to computer science, engineering and mathematics. If my research experience has taught me anything, it is that discovery often happens outside our comfort zone and we must be willing to accept being uncomfortable if it means learning something new.

While my work focuses on plant fitness, I really love spending time on my own fitness. A successful day for me contains either a CrossFit workout or getting out on my bike. No matter the state of fitness, I believe the world is never brighter than after a good cup of coffee.

While there are numerous ways that plants continue to fascinate me, what I find most compelling about these organisms is their incredible ability to adapt to stress. Some might assume that non-sessile organisms (ie. mammals) which can often flee, fight, or at least conceptualize stress, are more likely to succeed in such demanding environments. However, we continue to find captivating plant adaptations that allow them to excel in stochastic and inhospitable environments.  

What, then, makes one plant better at withstanding stressful environments over another? Are there specific adaptations that we can identify; and if so, can we use these “tools” to improve less tolerant crops? One mechanism that plants may use to become more tolerant is through alterations in (specialized) metabolism. Although there are numerous ways that this can arise, what I am most interested in is understanding how differences in time-of-day specific (circadian) regulation of specialized metabolism contributes to plant stress responses. My PhD research; therefore, explores this question in very tasty (and occasionally spicy) Brassica rapa cultivars, with a particular focus on sulfur-related metabolites. 

Before becoming a scientist, I was a thespian-bartender hybrid for many years. I continue to pursue both aspects as often as I can, although now-a-days this is usually through a Netflix-wine combo. My beautiful pup, Ella, sincerely appreciates these endeavors and is more than happy to provide her opinion should any show/movie not be up to her tastes. Our most recent non-lab related aspirations include: finding every vegetable that I can pair with Farro (it’s not Brassica, but it’s delicious and Ella agrees), discovering fun new things that the Twin Cities have to offer, and hopefully -finally! – really discovering who John Galt is.

​As an undergraduate, my exam final in introductory biology asked the question: “Plants are sessile and modular. How does this affect their life strategies?” This intentionally vague question was immensely influential in my life, though I did not understand it at the time.

In the Greenham Lab, I have been fortunate to learn techniques in plant gene editing, phenotyping, grant writing and greenhouse upkeep. My position also allows me to be part of several ongoing projects on characterizing circadian rhythms and plant stress response, which has been an immensely rewarding experience. We have begun doing preliminary work in characterizing the circadian dynamics of nectar production and pollinator attraction in Brassica rapa.
​
Outside the lab, I enjoy keeping tropical fish and houseplants, watching bad TV and playing video games.

I have always been interested in the biological sciences from a young age. Some of the first books I read supplied my brain with animal facts and identification. Although my interests now align with plant biology, I have kept the wonder of observing the differences between them and studying their evolution. I am especially fascinated by plant community interactions as well as plant resistances to extreme temperatures, pests, and drought.
 
Working for the Greenham lab has been highly enjoyable! So far, I have helped with a variety of tasks from plant care and seed collection to gene cloning and analysis to pollinator observations out in the field. There is always something new to learn about! While I am here, I hope to continue to learn more about the circadian rhythm in plants and how it guides the processes of Brassica rapa morphotypes.
 
Outside of work, I love to bike, draw, read, and hang out with friends! I also keep a variety of houseplants (terrestrial and aquatic), as well as a menagerie of pets including bunnies, fish, a leopard gecko, and a kitten.
