Dr. Carlos C. Goller
I am an Associate Teaching Professor in the Department of Biological Sciences and teach in the Biotechnology (BIT) Program at North Carolina State University in Raleigh, NC. My research interests include molecular microbiology, metagenomics, epidemiology, history of disease, science education, and open educational practices. I am also interested in teaching with technology and the scholarship of teaching and learning.

Gold and precious metals are in high demand. The increased desire for electronic components requiring gold and other metals and the environmental impact of mining present a challenge to developing sustainable sourcing methods. Fortunately, microbial communities have found ways to cope with gold toxicity by using unique genetic mechanisms to reduce toxicity and increase competitive advantage in bustling cities of microbes. One such fascinating microbe is Delftia acidovorans.
Delftia have over 50 kilobases of sequence dedicated to producing a non-ribosomal peptide that allows precipitation of gold and kills pathogens, including methicillin-resistant Staphylococcus aureus (Johnston et al. 2013, Tejman-Yarden et al. 2019). For the last five years, we have leveraged the power of citizen scientists on our campus and high-throughput (HT) approaches to catalyze the discovery and better understanding of Delftia in numerous courses at NC State and NC Central University (Riley et al. 2020).
