Rodolphe has worked on beneficial microbes, focusing on the occurrence and diversity of lactic acid bacteria in fermented foods and as probiotics. Using functional genomics, he has focused on uncovering the genetic basis for health-promoting traits, including the ability to uptake and catabolize non-digestible carbohydrates. He spent 9 years at Danisco-DuPont, characterizing probiotics and starter cultures, and established the functional role of CRISPR-Cas, as adaptive immune systems in bacteria. He has focused on establishing the molecular basis for their mechanism of action, as well as developing and applying CRISPR-based technologies for genotyping, building immunity and genome editing.

Yong Jun Goh
Hometown: Kuala Lumpur, Malaysia
Past Education: BS Food Science & Technology, University of Nebraska-Lincoln; PhD Food Science & Technology, University of Nebraska-Lincoln
Jun is a Senior Scientist in the group and provides leadership to the functional genomics program, with core responsibilities in study design, the development of murine study platform, genetic tools and phenotypic assays, managing prebiotic research, and graduate student mentorship. Jun's research focuses on gene function discovery in probiotic microbes that contributes to their host fitness and immunomodulatory activities in the gut epithelium. Her interests include in vivo transcriptome studies of probiotic lactobacilli, the functions of S-layers and cell surface components on gut retention and immunomodulation, molecular mechanism of prebiotic oligosaccharides utilization by gut microbes, and she recently discovered the link between glycogen biosynthesis and in vivo gut competitiveness. With her previous experience in establishing a upp-based counterselective gene replacement system for L. acidophilus, Jun is presently working on developing a CRISPR-Cas9 based tool for programmable genome editing in lactobacilli.
Hometown: Wicklow, Ireland
Past Education: BA (Mod) Microbiology, Trinity College Dublin Ireland; PhD Microbiology National University of Ireland, University College Cork, Ireland
Sarah's graduate research concerned the study of bacteriophage and lysins as potential anti-microbial agents against Staphylococcus aureus. Sarah moved to the United States from Ireland after obtaining her Ph.D and joined the laboratory of Dr. Todd R. Klaenhammer as a postdoctoral research associate where she researched functional genomics of lactic acid bacteria and probiotic-host interactions. Currently as a senior research scientist, she continues research on functional genomics, probiotic-host interactions, developing the murine research platform, and is the lead scientist for the vaccine program which focuses on mucosal vaccine delivery systems using lactic acid bacteria. Her research also involves methods to improve on existing genetic systems and to identify new antigen and therapeutic targets. Sarah provides research assistance and supervision to staff, postdoctoral researchers and graduate and international visiting students across various research topics.

Claudio Hidalgo Cantabrana
Hometown: Oviedo, Spain
Past Education: BS Biology, University of Oviedo; MS Food Biotechnology, University of Oviedo: PhD Microbiology ,University of Oviedo
Claudio has worked on functional and genetic characterization of exopolysaccharide production by several bifidobacteria strains. During his PhD he studied the gene clusters involved in EPS production in Bifidobacterium animalis subsp. lactis, developing knockouts, studying the chemical composition of EPS and performing in vitro, ex vivo and in vivo assays to probe the immune modulation capability of bifidobacteria and EPS. Now a days, he is working at NCSU as a post-doctoral researcher in Barrangou’s lab focused on CRISPR and probiotics to develop new applications of CRISPR regarding probiotic genome enhancement, vaccine delivery and antimicrobials in new probiotics species of Lactobacillus and Bifidobacterium. Claudio provides research assistance to graduate students in probiotics and genetics areas.
