I am the Principal Investigator of the Washington DC Metropolitan Women’s Interagency HIV Study (WIHS) and a member of the DC developmental CFAR where I actively assist investigators transitioning to HIV research. I am a site investigator for the Georgetown University AIDS Clinical Trials Unit and was site PI on the recent study of the HPV vaccine in HIV infected women. I have been involved in all of the major substudies of the WIHS and I was the site investigator for the WIHS related RO-1 clinical trial, Pharmacology for Hazardous Drinking in HIV-infected Women. I have experience both in clinical trials and in observational cohort studies. Additionally as former Chair of the Georgetown IRB, I bring expertise in issues related to the protection of human subjects and of regulatory issues related to the conduct of research. In my capacity at WIHS, I oversee a research team of epidemiologists and biostatisticians who support affiliated proposals.

My laboratory focuses on the two most common fungal pathogens of immunocompromised patients - Candida albicans and Aspergillus fumigatus. We use molecular biological and biochemical approaches to identify new targets on these fungi that can be exploited in drug discovery. Supported by an NIH-NIAID grant, I performed anti-fungal drug discovery with a medicinal chemist to evaluate their in vitro inhibitory activity against a panel of fungal pathogens. Four of those compounds are now in patent. My research interests also include genomic mining of mitochondria to identify fungal-specific genes specific to electron transport chain complex I. Our observations may point to the use of anti-mitochondrial complex I compounds that synergize with standard azole therapies. I am interested in the colonization by Candida species of the oral and vaginal mucosa among WIHS participants.

I am a psychologist with trauma expertise who has worked in low-income urban communities for over 15 years. Many of these communities are affected by multiple traumas that include HIV/AIDS, substance abuse, community violence and interpersonal violence. My research with the WIHS study aims to improve highly active antiretroviral therapy (HAART) adherence in women with HIV and co-morbid depression and trauma. Previous research has found that depression and psychosocial factors associated with depression and trauma (e.g. isolation and lack of social support) contribute to poor medication adherence. Besides this study, I have several other ongoing research studies related to HIV/AIDS: understanding decision-making around maternal disclosure of HIV, developing an intervention for women living with HIV/AIDS who have histories of trauma and addictions and investigating the traumatic life histories of women living with HIV.

My research investigates how menopause affects the innate immune system in the female reproductive tract, altering susceptibility of postmenopausal women to HIV. This involves characterizing innate anti-HIV activity and determining the levels of protective anti-HIV innate immune factors as well as pro-inflammatory HIV enhancing immune factors in the genital secretions of postmenopausal women compared to those found in premenopausal women. Results of this study may prove highly relevant given that more women than men are being affected by HIV and the population of HIV-positive postmenopausal women are on the rise.

I have a PhD in Cultural Anthropology from Syracuse University, and an M.Phil. in social Medicine and Community Health, Jawaharlal Nehru University, New Delhi, India. My research expertise has focused on qualitative methods and mixed methods. My research interests include HIV risk behaviors, sexuality, reproductive health and gender. I have conducted research in the US, India, Ghana and Nigeria. I have also worked with international public health organizations in program planning, monitoring & evaluation of programs and capacity building in gender. In WIHS, I have conducted research on women’s perspectives on men-on-down-low, aging with HIV, disclosure of HIV status, and alcohol consumption. I am currently looking at the use, knowledge and acceptance of biomedical technologies Pre-Exposure Prophylaxis (PrEP), Post-Exposure Prophylaxis (PEP), and Treatment as Prevention (TasP) for prevention of HIV infection among women.

The majority of my past and current research has made use of three advanced MRI techniques: fMRI rapid adaptation (fMRI-RA), local regional heterogeneity (Hcorr), and multi-voxel pattern analysis (MVPA). Although I perform research on subject areas outside of the HIV/AIDS realm, I use WHIS study data in conjunction with these imaging techniques in my own lab. Two ongoing projects include (1) a DC D-CFAR funded study in which fMRI-RA techniques are being used to develop optimal experimental design for conducting fMRI-RA studies on people with HIV-infection and to study the change in neuronal selectivity in HIV-infected middle-aged adults, and (2) a NCRR funded project in which MVPA and DCM are being used to investigate the neural dysfunction of executive function. In collaboration with WIHS researchers, I am investigating the neuropathological change in middle-aged men and women with HIV-infection, as well as the neural basis of HIV-associated neurocognitive disorder (HAND) in the context of aging.

My laboratory is focused on defining transcriptional and chromatin mediated regulation of HIV and HTLV-1 infected cells.  Our studies have resulted in novel concepts regarding promoter-bound proteins that regulate all events of mRNA biogenesis (including capping, elongation, termination, poly A addition, splicing), nuclear-cytoplasmic transport, and activation of nonsense mRNA degradation. Among biothreat agents, the Kashanchi lab is interested in Rift Valley fever virus (RVFV) and Venuzueln Equine Encepalitis virus (VEEV) replication in vitro and in vivo and defining crucial host-pathogen interactions that are imperative to pathogenesis.

I am a co-investigator at the DC WIHS, clinical Infectious Diseases physician, and epidemiologist who trained at Stanford University. Having grown up in Ethiopia during the early years of the HIV epidemic, I have a strong interest in improving access to high quality care for those with limited resources. A particular interest of mine is in HIV during pregnancy, and in the prevention of mother-to-child transmission of HIV, an area that I focused on while at the Elizabeth Glaser Pediatric AIDS Foundation. Recently, I joined Georgetown University while continuing to provide HIV clinical services within the community. My plan is to study the molecular epidemiology of HIV; HIV drug resistance; and HIV/HCV co-infection to further our mission towards improved HIV treatment and prevention strategies for women and their families.

I serve as co-principal investigator and therapist for a pilot study that is adapting Interpersonal Psychotherapy as a telephone-based mental health intervention for women in the Washington, DC WIHS who have HIV infection and major depressive disorder. The aim of the study is to adapt an evidence-based treatment for depression specifically for urban women who experience multiple stressors and have low social support in addition to depression and HIV infection. I am examining whether the intervention positively impacts mood and interpersonal functioning, as well as assessing whether a mental health intervention delivered via telephone, helps with adherence to HAART medication.

I am an HIV/AIDS epidemiologist, and have been working with 2 large HIV/AIDS cohorts since I studied as a Ph.D. student: MACS and WIHS. While at University of California Los Angeles, I used data from the Multicenter AIDS cohort study (MACS) to examine genetic determinants for resistance to HIV infection among MSM. During my work at Johns Hopkins University as a postdoctoral researcher, I used data from both MACS and WIHS to examine impacts of HIV infection and HAART use on quality of life of HIV infected individuals. Since joining Georgetown University, I have been using WIHS data to conduct a variety of independent studies, including research on serosorting sexual behavior, genetics, neuroscience, HIV treatment effectiveness assessment, drug interaction and complementary and alternative medicine. My secondary role in WIHS includes collaboration with external investigators to help them make use of WIHS data and secure funds. Some of these efforts include studying the effect of HIV infection on neurotrophin levels, examining neurocognitive function of WIHS women using fMRI technique, and analyzing effects of HIV infection on microvascular dysfunction.

The primary goal of my research is to provide answers to common clinical questions that lack evidence and improve patient care. As a natural extension of my clinical training in family practice, my research portfolio is varied. I conducted what is believed to be the first adult primary care clinical trial in acute rhinosinusitis in the United States. I have also conducted studies on overusage of diagnostic tests and examined ways to decrease antibiotic usage. I am currently conducting a U01 AT003600-01A1 that required collaborative work with the FDA for over a year to acquire investigational new drug (IND) approval. My lab has also lead six other RCTs in the last 6 years, enrolling and retaining over 1,400 participants. I have also lead microbiome research using HIV + and – women recruited from the WIHS. We evaluated the steady state of candida colonization of the oral and vaginal mucosa, finding that the percentage of participants that were positive for Candida species from both the oral and vaginal mucosa was higher in the HIV + than in the healthy control. I have extensive experience with following adverse events, supervising research personnel, overseeing large budgets, complying with regulatory issues and many other aspects of conducting a high quality study. I have been working with the WIHS databases for the last seven years, with a concentration on complementary and alternative modalities and the impact family plays on HIV.

My research investigates mechanisms of HIV neurotoxicity with an end-goal to develop new adjunctive therapies to prevent or reduce HIV-mediated neuronal injury. This project involves determining the molecular and cellular mechanisms underlying the neurotoxic effect of HIV and the viral protein gp120 in the WIHS cohort. Additionally, we are testing the effect of HIV on the BDNF neurotrophin. This is an area of high relevance for human neurological diseases because lack of BDNF is a risk factor for developing neurological alterations. Other past research projects includes several NIH-funded grants that developed animal models of HIV dementia, and other pathologies relevant to human chronic diseases.

In the past decade, much of my research has focused on gender, culture, and health, especially relevant to HIV/AIDS. I have been especially interested in how individuals perceive the risk of their own behavior, and whether that perception of risk influences change in behavior or the adoption of safer behaviors. I am currently on the Executive Committee of the GW HIV/AIDS Institute, and am a co-director of the Behavioral Science, Public Health, and Biostatistics Core of the DC D-CFAR, 2010-2015. Some of my current and previous projects include (1) HIV Prevalence, Sexual Behavior, and Attitudes toward Circumcision among Colombian MSM, (2) Contextual Factors on Sexual Risk among Latino MSM and (3) Disclosure of HIV Status among Latino Gay Men. I am collaborating with WIHS on a research study on Disclosure of HIV status to Family and Friends: Impact on Health outcomes.
