@LazearLab

Helen grew up in Calgary, Alberta, Canada and majored in Biochemistry at the University of Alberta. She received a Ph.D. from the University of Pennsylvania, where she studied herpes simplex virus neuronal transport in Harvey Friedman's lab. Her postdoctoral research, with Mike Diamond at Washington University in St. Louis, focused on innate immune control of West Nile virus pathogenesis. She joined the Microbiology and Immunology Department at UNC in Fall 2015. Work in the Lazear Lab focuses on pathogenic mechanisms of flaviviruses and the innate immune mechanisms that determine tissue and species tropism

Derek Carbaugh

PhD Candidate

dcar5 [at] email.unc.edu

Derek grew up in Lancaster, PA and majored in Biology at Millersville University of Pennsylvania. He did a summer undergraduate research experience (SURE) internship at UNC-CH in the genetics department prior to his last semester of undergraduate studies. He is now a 4th-year PhD student in the Microbiology & Immunology program. His work currently focuses on understanding viral and host determinants of Zika virus pathogenesis.

Cesar Lopez

PhD Candidate

cesar_lopez [at] med.unc.edu

Cesar grew up in Modesto, CA, and received his BA from Rice University in Philosophy as well as Biochemistry & Cell Biology. He worked in Jason Kimata's lab at Baylor College of Medicine as an undergraduate, studying innate immune restriction of SIV by SAMHD1, as well as a summer internship with Peter Hotez studying a Trypanosoma cruzi vaccine. He is currently a 4th-year MD/PhD student in the Microbiology & Immunology program, investigating how prior dengue immunity affects congenital and sexual transmission of Zika virus.

Becca Casazza

PhD Candidate

rcasazza [at] email.unc.edu

Becca is originally from New England; she grew up in Bedford, NH and received her BA in Biology from College of the Holy Cross in Worcester, MA. There she began her research training in the lab of Dr. Ann Sheehy studying the anti-HIV mechanisms of the Apobec3G protein. Becca is a 3rd-year PhD student in the Microbiology & Immunology program; her research in the Lazear Laboratory focuses on understanding the role of interferon lambda in restricting congenital infections such as Zika and rubella viruses.
