Laura Doepker, PhD

Title: Postdoctoral Fellow

2016-present
I study the evolution of human antibody responses directed against HIV-1 infection.  We sequence antibody genes from B cells within longitudinal patient blood samples to estimate how their HIV-specific antibody lineages developed.

Joshua Marceau, PhD

Joshua Marceau, PhD

Title: Postdoctoral Fellow

2018-present
I am interested in defining which interferon-stimulated genes are involved in the restriction of lentiviruses.

Mackenzie Shipley, PhD

Mackenzie Shipley, PhD

Title: Postdoctoral Fellow

2019-present
I am currently working on isolating and characterizing HIV-specific broadly neutralizing antibodies from women who are superinfected with HIV-1. Superinfection with two distinct viral strains generates a broad polyclonal repertoire of neutralizing antibodies targeted to HIV. Understanding how these antibodies evolve and develop may assist future vaccine design.

Title: Postdoctoral Fellow

2019-present
I am interested in flavivirus biology and circulation in Africa. I will develop methodology to surveil global presence of Zika and other flaviviruses with high specificity, and will investigate genes that govern innate immune responses during infection.

Title: Graduate Research Assistant

2017-present
I am interested in studying the function and epitope of antibodies that potentially mediate protection from HIV, with the goal of informing HIV vaccine design.

Title: Graduate Research Assistant

2019-present
I am interested in applying high-throughput techniques to identify interferon-induced genes that are potent inhibitors of early viral infection and replication (restriction factors).

Feli Ruiz

Feli Ruiz

Title: Graduate Research Assistant

2020-present
I am broadly interested in host-pathogen interactions and the evolution of the immune system to target human pathogenic viruses. Specifically, understanding the natural evolution of broadly neutralizing antibodies in HIV-1 infected individuals to inform vaccine development.

Title: Graduate Research Assistant

2020-present
I am interested in studying mechanisms of innate and adaptive immunity to emerging viruses, including Zika virus and SARS-CoV-2.

Zak Yaffe

Title: Graduate Research Assistant

2019-present
I am interested in studying the evolution of both neutralizing and non-neutralizing antibodies in HIV-1 infected individuals. I would also like to better understand how effector functions influence whether a given antibody will be beneficial or detrimental in the context of HIV infection.

2020-present
I am interested in the intersection of microbiology and global public health, particularly as it pertains to viruses.  I believe that understanding disease from the molecular level all the way to the population health level can help us achieve a healthier world.

Title: Research Technician

2021-present
I am interested in how CRISPR-Cas9 technology can be used to study the innate immune response to HIV and SARS-CoV-2.

Title: Research Technician

2008-present
I perform Gen Probe QC HIV viral RNA loads and population based sequencing for resistant mutations for women on ARV for the QRS cohort. I’ve also been involved with neutralization assays using the PBMC and TZM methods for PBMC and 293T-passaged chimeras with monoclonal antibodies.
