My interest is in combining immunology with bioengineering to understand how our bodies deal with the invisible but rich microbiological world in which we are immersed.

I'm also a co-founder of Day Zero Diagnosticsan early start-up that's developing a diagnostic for rapidly identifying the species and antibiotic susceptibility of bacterial infections using whole genome sequencing and machine learning.

In my free time I love to travel, take photographs, and spend time with my wonderful husbanddaughter, and friends.

Depo-Provera and Nur-isterate modulate host inflammatory responses and HIV acquisition risk in women. The existing paradigm is that vaginal monocolonization by Lactobacillus is normal, and encroachment by other bacteria is pathologic. By characterizing cervicovaginal bacterial communities in a cohort of young South African women using 16S rRNA and shotgun sequencing, we found that the majority of participants had low Lactobacillus abundance and high ecological diversity.

One diverse Prevotella-containing community type strongly correlated with increased female genital inflammation and a 4x higher HIV aquisition rate compared to women with Lactobacillus crispatus dominance. Members of the Prevotella-containing bacterial community induced genital epithelial cells and antigen presenting cells to secrete the same cytokines that we found in vivo, partially through LPS sensing via TLR4.

Our results identify specific bacterial species that not only alter the inflammatory state of the FGT but more broadly impact a woman's risk of acquiring HIV, and we raise the hope of novel preventative therapeutics.

We also investigated the immunological effects of IPCs, the most common form of birth control in sub-Saharan Africa.

Although highly effective as a contraceptive, IPCs are controversially associated with increased HIV susceptibility by an unclear mechanism. We found that IPC users had a 3-fold higher risk of acquiring HIV than women not using a long-term family planning method.

INTRODUCTION

Phenotypic cellular analysis revealed that IPC users also had a significantly higher frequency of activated HIV target cells in the cervix. Since the availability of target cells in the genital mucosa enables early viral replication, recruitment or retention of these cells, the association between IPC use and target cell availability may explain the observed increased HIV acquisition rates in these women.

Furthermore, IPC use was not associated with differences in genital cytokine levels, indicating that cervicovaginal bacteria and exogenous progesterone increase HIV susceptibility by unique pathways. As part of my rotation project, I made a small contribution to the elucidation of a new mechanism of T cell exhaustion and dysfunction in the gut of HIV-infected people by determining the cellular subsets expressing E-cadherin in the lamina propria.AMPs are generally considered as positively charged small peptides, comprising about 12 −50 amino acids,,.The availability of the positively-charged amino acids, such as lysine and arginine, confers a general positive net charge to the AMPs.
