Professor & Chair · she/her/hers


My research focuses on plants! My love of plants started with some inspiring professors in college at the University of New York, Binghamton and continued afterwards as I worked a few years after graduation at a local landscaping nursery learning the basics of plant horticulture. Working at the nursery made me think a lot of the enormous variety in plant traits like leaf shape, root systems, colors, flowers, size, cold resistance (the list goes on and on). All of these observations made me realize I was very interested in learning more about how plants develop, so I applied to graduate school and studied the physiology of fruit set and ripening in Washington navel orange at the University of California, Riverside. I had supportive mentors and labmates and loved the weeks of orange and avocado harvests when we could come home with buckets of each (lots of fresh OJ and guacamole). While in graduate school, I was able to meet a lot of new people from different backgrounds and perspectives. I realized through courses and thoughtful discussions that I had a deep interest in the molecular processes underlying plant development; this is what I continue to investigate in my lab here at WWU with the help of both graduate and undergraduate students.

Beyond the lab and research, I’m a mom, wife and cat owner. My family loves to travel when possible, both near and far. We try and spend lots of time outdoors and enjoy hiking and downhill skiing, so the PNW is a really great fit for us. Sometimes I feel like am the only person in Bellingham that doesn’t kayak, but do I get out on Galbraith for mountain biking with friends when I can and enjoy the great views from trails.

Research Interests

Plant genetics, Developmental mechanisms, Transcriptional regulation, Microscopy

The broad research interest of the lab is to explore the molecular underpinnings of developmental processes. I use the model organism, Arabidopsis thaliana, as a system to investigate some of the genes involved in cell division and cell-type differentiation.  Why does a cell differentiate instead of divide? To investigate these processes, we use tools from molecular biology, microscopy, and reverse genetics. We are currently investigating the transcriptional regulation of key regulators involved in the production of small pores on the surface of all land plants called stomata. These structures allow for efficient gas and water exchange between the plant and it environment. New discoveries in the lab may take us into investigating root development and stomata function as well.
