- Incoming Grad Student: Michael Mulroy will be joining the Geoecology Lab for his graduate studies this coming fall. A warm welcome to him. Michael hails from Carpinteria, California. He graduated in 2010 from Pomona College with a degree in Environmental Analysis. Since then, he has spent 6 years in the San Francisco Bay Area working as a wildlife biologist, and recently completed 2 years of service as an Environmental Conservation volunteer with the Peace Corps in Panama. Currently, Michael is working as a field technician and biologist for Channel Islands Restoration. Michael is broadly interested in species diversity and ecology, as well as how plant communities change across spatial and temporal scales, and how these changes relate to patterns of historic and present-day land use and management. At Cal Poly, Michael looks forward to investigating lichen communities of serpentinite substrates. In his free time, Michael enjoys reading, riding his bicycle, birding in remote areas, searching out edible mushrooms, and most recently, identifying lichens. Congratulations, Michael!
- Incoming Grad Student: Roisin ‘Rosie’ Murphy-Deak will also be joining the Geoecology Lab for her graduate studies this coming fall. A warm welcome to her! After graduating from UC Davis with a degree in Environmental Science and Management Rosie has pursued botanical field work that brings her far and wide. For the last seven years she has spent her time in the employment of various agencies including UC Davis, CNPS, and the US Forest Service. She is broadly interested in disturbance and the maintenance of biodiversity on the landscape and using insights gained from the field to inform land management practices. She is planning a collaboration with the US Forest Service to investigate how controlled burns can be used to maintain meadow diversity and whether they are effective means of preventing Pine invasion. Congratulations Rosie!

Amber Williams is a 4th year Biological Sciences student concentrating in Ecology. She is working under Dr. Rajakaruna through the STEM Teacher and Researcher (STAR) program, which aims to produce excellent K-12 STEM teachers by providing aspiring teachers with opportunities to do authentic research while helping them translate their research experience into classroom practice. This summer, she is working alongside undergraduate research student and Garden Club of America scholar Mary Devlin exploring the effects of nutrient enrichment in serpentine soils on native and non-native species.
