My research explores how rapid climate-driven changes in sea ice are altering the microscopic algae that form the base of Arctic and Antarctic marine food webs. I am particularly interested in how sea ice decline is altering the community composition, physiology, and nutritional value of microalgal communities, particularly during key seasonal periods such as the spring bloom and autumn freeze-up. My work combines extensive Arctic field observations with a wide range of tools including molecular, chemical, and microscopy-based approaches. Ultimately, my research aims to better understand how declining sea ice will transform energy flow and carbon cycling in polar oceans.
