Undergrads

Natalie Gonzalez
My research in the Parker Lab looks at the effects of cover crops on microbial communities. Although it’s understood that cover crops are used between growing seasons to prevent soil erosion and mitigate disease, little is known about the impact of the cover crops on soil microbe communities. I’m working with environmental DNA (eDNA) extracted from soils collected before and after the introduction of cover crops at the UCSC farm. My research makes use of metabarcoding, next generation sequencing technologies, and bioinformatics to answer the question of how cover crops affect soil microbial communities. I’m a plant molecular biologist in the making!
Martin Genova
I am currently working on a project at Elkhorn Slough National Estuarine Research Reserve with Karen Tanner to look into the feasibility of using Biochar (basically charcoal!) as a restoration tool to increase transplant success of five native salt marsh plant species. The benefit of biochar is well studied in agriculture but not so much under a restoration context in salt marsh ecosystems. I use observational techniques to assess differences in long term plant growth between treatments of varying additions of biochar to salt marsh soil.
Elizabeth Davis
Dean’s Award for Undergraduate Research A Widespread Nitrogen-fixing Invader Experiences Negative Soil Feedbacks Despite Increased Root Nodulation and Mycorrhizal Colonization. I researched plant-soil feedbacks in the invader Cytisus scoparius predominantly focused on the interactions between C. scoparius and soil biota. Currently I am continuing to collaborate with Ingrid Parker and Sara Grove to publish our research on plant-soil feedbacks.
Sarah Berman
I worked with Karen Tanner on the Elkhorn Slough salt marsh project and Sara Grove on Douglas Fir and Scotch Broom interactions. My senior thesis was under Karen Tanner and focused on the effects of different saline concentrations and water volumes on halophyte physiology. Some of my favorite memories include getting stuck in the mud while planting Jaumea carnosa, my first tick encounter, and endless bargaining with the Decagon WP4! I graduated in 2018 and am currently working as a research associate at Mendel Biological Solutions, focusing on the effects of applied natural products on crop plant.
