Alexander R. Bazazi
Year started: 2012
Alexander Bazazi is in the MD-PhD Program at YSM and the Department of Epidemiology of Microbial Diseases at YSPH. His research focuses on quantitative methods for evaluating harm reduction interventions and characterizing the epidemiology of HIV among people who inject drugs. Currently, he is studying the epidemiology of HIV among people who inject drugs in Malaysia and is evaluating a drug treatment intervention for incarcerated opioid-dependent individuals living with HIV. Alex has methodological interests in techniques for generalizing randomized controlled trial findings, drawing causal inference with observational data, and network-based sampling methods.

My research interests broadly include the spread of infectious agents through populations and the interventions that seek to limit or reverse epidemic spread. I am most interested in the transmission of infectious agents and the variability of immune responses to pathogens.
Year started: 2011
Research interest: I use diverse methods from operations research, disease modeling, economics and decision science, stochastic processes and other quantitative disciplines to improve the conduct and impact of programs to treat and prevent infectious diseases. I also co-direct the Yale Global Health Justice Partnership, where I explore the relationship between public health and medicine, human rights and politics with students and faculty from Yale Law School, Yale School of Public Health and Yale School of Medicine.

I am interested in endemic and epidemic dynamics of infectious diseases, and relatedly in Bayesian and maximum likelihood methods for parameter estimation in partially-observed systems. In my dissertation work I seek to contribute a differential equation modeling framework linking within-host competition to inter-host transmission dynamics of Streptococcus pneumoniae.

Kelsey Loeliger was admitted to MD/PhD program in 2011, affiliating with the Epidemiology of Microbial Diseases Department in 2013 after three years of medical school. She is interested in conducting clinical and community-based research with an emphasis on marginalized populations and the social constructs surrounding infectious diseases. Her work is aimed at developing a better understanding of the many interconnected factors that play a role in the prevention, progression, transmission, and treatment of these diseases. Her most recent ongoing research with Dr. Gerald Friedland and Dr. Sheela Shenoi explores the personal and systematic barriers HIV+ patients face with regard to initiating and adhering to antiretroviral therapy (ART). Under the direction of Dr. Frederick Altice, current areas of interest also include women with substance use disorders in Malaysia and how the interplay between substance abuse, HIV/AIDS, mental health disorders, and violence as well as other social circumstances impact the health of the individual. Prior to joining the MD/PhD program, Kelsey earned a B.S. in Biological Sciences from University of Maryland-Baltimore County where she studied the retroviral mechanism for genome packaging in the Howard Hughes Medical Institute biochemistry laboratory of Dr. Michael Summers. After graduating, she worked as a post-baccalaureate research fellow (IRTA) at the National Heart Lung and Blood Institute where she conducted translational research on the role of chronic inflammation in Myelodysplastic Syndrome and Aplastic Anemia.

Katharine (Katie) Owers
Year started: 2013
I am interested in applying advanced quantitative methods to questions of disease transmission and natural history in complex ecological settings. My doctoral research applies a variety of spatial and temporal analytical methods to questions about leptospirosis, an environmentally-transmitted zoonotic disease.
Year started: 2015
Research interests:My primary interest is in identifying how HIV and TB screening strategies can be optimized to increase testing uptake and to improve the cascade of care. My past research has focused on the evaluation of novel diagnostics for HIV and TB in China and South Africa. Prior to attending Yale, I received a BA in Neuroscience & Behavior and Sociology from Columbia University and an MSc in Epidemiology from the Harvard T.H. Chan School of Public Health.
Year started: 2011
Katharine is fascinated by the histories contained within pathogen genomes. She uses genomic information to ask questions about how pathogens evolve and how they move across space. She is particularly interested in how vector-borne and zoonotic pathogens respond to changes in climate and biodiversity. For her dissertation research, she is investigating the origins and emergence history of the Lyme disease bacteria, Borrelia burgdorferi. This project incorporates spatial modeling and bacterial phylogeography to reconstruct the invasion history of Lyme disease in North America.
