Noelymar González-Maldonado, PhD Student
Noely grew up in Lares, Puerto Rico. She pursued a B.S. in Agricultural Sciences at the University of Puerto Rico at Mayagüez where she did undergraduate research in saline-sodic soil management in semiarid tropical agroecosystems. After her undergraduate studies, she pursued a M.S. in Environment and Natural Resources at the Ohio State University with Dr. Steve Culman. Her master’s project focused on studying the long-term and temporal effects of no-till and crop rotations in soil health focusing on labile soil organic matter dynamics and crop (corn and soybean) productivity. During that time, she co-founded the Women in Ag Science collective, a platform to connect, support and empower women in the agricultural sciences. Currently, Noely is pursuing a PhD program in Soils and Biogeochemistry at UC Davis with Dr. Cristina Lazcano where she will be focusing her research in managements impacts on soil health and crop productivity/quality from the soil biology perspective.


Connie (Tsz-Fai) Wong, PhD student
Originally from Hong Kong, Connie moved to the US upon completion of secondary education and obtained a B.S. in Biology at California State University, Fresno. During the gap years after her undergraduate studies, she had a brief experience working in the wine industry which sparked her interest in Soil Science and sustainable agriculture in vineyards and other cropping systems. She pursued a M.S. in Agriculture with a Specialization in Soil Science at California Polytechnic State University, San Luis Obispo, and her Master’s Thesis focused on the effects of compost application on soil carbon and greenhouse gas emissions in a California Central Coast vineyard. She is currently a Ph.D. student in Soils and Biogeochemistry working with Dr. Cristina Lazcano at University of California, Davis. Her research interests are soil biology and microbiology, soil health, sustainable and regenerative agriculture.


Halima Malal, visiting Fulbright PhD student 
Halima MALAL was born in a small town named Aourir Near AGADIR city in Morocco. After two-year technical degree in industrial and biological engineering, she obtained her associate degree and succeeded in integrating the Faculty of Science and Technology of Marrakech for the preparation of an engineering degree in Industrial and Food Safety. she was interested in the environmental aspect in general, and particularly in sustainable agriculture and the production of healthy food. Currently, she is a PhD candidate in environmental science at Ibn Zohr University, Agadir, Morocco, under the supervision of Dr. LAKHTAR Hicham. she is working on the amelioration of vermicompost process and studying its application on sustainable agriculture. recently she joined UC Davis as a visiting scholar after obtaining a Fulbright grant, she well works with Dr. Cristina Lazcano about the effect of organic amendment on microbial community of soil under abiotic stress conditions.


Erika Yao, Junior Specialist
Erika graduated from Cal Poly, San Luis Obispo where she earned a BS degree in Environmental Earth and Soil Science with a concentration in hydrology and a minor in watershed management. She has been involved in various research projects as an undergraduate, from looking at how natural soil thickeners can reduce landslide risk to land rehabilitation through the regrowth of native vegetation. Her research interests lie in the overall impact of humans on the environment, but more specifically, the sustainable interactions between humans and soil. She is currently researching the health of vineyard soils in Napa and Paso Robles, CA.


Courtney Emerson, MS Student 
Courtney is a Washington, D.C. native. In 2020, she graduated from the University of Pittsburgh, receiving a Bachelor of Science in Environmental Engineering, where her focus was on sustainable, organic, and commercial farming methods. She interned at organic farms in Gales Creek, OR, and Hilo, HI, and studied Agroecology in France at the National Institute of Applied Sciences in Lyon (INSA Lyon). Her current research concerns salinity management and soil health in California processing tomatoes and she wishes to continue regenerative agriculture research and extension in the future.


Luisa Robles, Student Research Assistant 
Luisa is a senior undergraduate student majoring in Environmental Science and Management with a focus on Soils and Biogeochemistry at the University of California, Davis. She is working as a Student Research Assistant helping both in the field and in the lab. She is interested in managing agricultural soils to ensure food security, improve soil health, improve crop resiliency, and mitigate global climate change through carbon sequestration. Other strong interests include soil restoration.



Anna Marrs, Student Research Assistant
Anna Marrs is a 4th-year Sustainable Agriculture and Food Systems student with an emphasis on agriculture and ecology. She is currently working as a student research assistant focusing on the relationships between soil health and water management of California tomatoes. She has interests in the ecological restoration of soils and biodiversity, as well as the balance between soil health and crop productivity.


Claire Kisliuk, Student Research Assistant
Claire is an undergraduate senior majoring in Plant Sciences with an emphasis in soils. She currently works in the lab as a research assistant. She is interested in management of soils to benefit soil health, increase food security and mitigate climate change, as well as policy to support small-scale farmers utilizing practices to conserve and benefit soil.
