Lauren Steinbaum comes to us from Stanford University, where she recently completed a PhD in Environmental Engineering and Science. For her PhD, she investigated environmental transmission of soil-transmitted helminths, a type of intestinal worms that infect humans, in rural homes in western Kenya. Her PhD focused on disease transmission on at the micro-level (she actually used a microscope!), and she is excited to learn more about macro-level (i.e. population-level) disease transmission as a postdoctoral researcher in the Bellan lab.

Rachel Mercaldo obtained her Bachelor’s degree from Pennsylvania State University, where she majored in mathematics until she discovered Fourier Series and began incorporating biology and chemistry into her degree. While at Penn State, she studied the effectiveness of Agion® Antimicrobial. She also had the opportunity to attend a research experience at the Odum School of Ecology at UGA that cemented her interest in infectious disease transmission. She is particularly focused on Zika virus and enjoys leading a committee in the Epidemiology and Biostatistics department’s new Zika working group. Rachel can be contacted via email at .
