Biography

I am a native Texan that grew up swimming and boating on the rivers and lakes of central Texas. As a first generation college student, I had no idea that these waterbodies of my youth were filled with tiny green microorganisms that would inspire my passion for biology. My research interests involve the reciprocal interactions between microorganisms and their chemical environment, with a particular interest in the photosynthetic and heterotrophic microorganisms in lakes. Research projects in my lab often address how human alterations to landscapes impact the ecology and chemistry of lakes, and how resulting water quality can reciprocally influence human welfare.
