Current Lab Members


Helen Chu

M.D. M.P.H., Assistant Professor

Dr. Chu earned her M.D. at Duke and her M.P.H. at the University of Washington. She is board certified in both Internal Medicine and Infectious Disease. Her research is focused on maternal vaccines, in particular vaccines against influenza and respiratory syncytial virus. She studies the virologic and immunologic correlates of protection from respiratory viral infections in mothers and infants in rural Nepal and performs clinical trials of vaccine candidates in both domestic and international sites.


Kira Newman

M.D. P.h.D., Internal Medicine Resident

I am an internal medicine resident. My research focuses on diarrheal disease immunology and epidemiology. 


Denise McCulloch

M.D. M.P.H., Infectious Disease Fellow

Denise earned her M.D. and M.P.H. in Epidemiology from Emory University in Atlanta, Georgia. She completed her Internal Medicine residency at New York University prior to beginning Infectious Disease fellowship at the University of Washington. Her research interests include viral epidemiology and emerging infectious diseases.


Seda Ekici

P.h.D., M.D. Student

I am a second-year medical student at the University of Washington. My research focuses on the characterization of the burden of respiratory viruses in pregnant women. 


Emily Scott

M.D. M.P.H.

I am a fourth year medical student headed into internal medicine. My research focuses on the molecular and community epidemiology of respiratory viruses. 


Alex Murray


Born and raised in Seattle, Alex started working in Dr. Chu's lab group in collaboration with Dr. Englund in 2014 after graduating from the University of Chicago in public policy. He is now a 4th year medical student at George Washington University and will be starting Pediatrics residency next summer. Within the lab group, Alex has focused on infantile viral respiratory disease, specifically protection via maternally derived antibody and the role of nasopharyngeal pneumococcal bacteria in viral infection.


Izzy Brandstetter

M.P.H., Research Coordinator

I completed my undergraduate degree in Chemistry from St. Olaf College, and my MPH in Epidemiology from the University of Washington. My research interests include infectious disease epidemiology and modeling, and infection prevention both domestically and internationally. 


Jessica Heimonen

M.P.H., Research Coordinator

I graduated from the University of Michigan with a degree in Biochemistry, then I received my MPH in Hospital & Molecular Epidemiology from the University of Michigan. My research interests include infectious disease and spatial epidemiology, though I am particularly interested in the transmission and severity of respiratory viruses.


Annie Emanuels

M.P.H., Research Coordinator

Originally from San Francisco, I am a second-year MPH student in Epidemiology at the University of Washington. My Master’s thesis focuses on the effects of viral coinfection on respiratory illness in a cohort of infants in Nepal. As an assistant in the Chu lab, I will be investigating the epidemiology and transmission dynamics of influenza on college campuses. As an undergraduate I studied biology and environmental science at Hamilton College in upstate New York before moving to Seattle for graduate school.  


Kiel Shuey

M.S., Research Scientist

Originally born and raised just north of Atlanta, I graduated from the University of Alabama with undergraduate degree in Microbiology and a Master’s degree in Cell Biology. My previous research experience has been in age-related and immune-mediated neurodegeneration in both Alzheimer’s and Parkinson’s disease models. My research interest is in immunology.   


Audrey Osterbind

B.S., Research Scientist

Originally from Alabama, Audrey graduated from Agnes Scott College with a degree in Biology and Classics. Prior to moving to Seattle, she worked with tick-borne bacterial pathogens in the order Rickettsiales at the CDC. The majority of her research was centered on better understanding the ecology of rickettsial diseases through both field and molecular work. Her research interests include molecular biology and immunology.


Caitlin Wolf

B.S., Research Scientist

Originally from Albuquerque, I graduated from the University of New Mexico with a degree in microbiology and chemistry and studied bacterial communities of streams in the McMurdo Dry Valleys, Antarctica. My current role in the Chu Lab is lab manager and running the specimen workflow for the Seattle Flu Study. I am interested in international women’s and maternal health initiatives and research. 


Jenni Logue

B.S., Research Scientist

I graduated from the University of Washington with a degree in molecular, cellular, and developmental biology and performed research using zebrafish as a model to gain a deeper understanding of the mechanisms underlying hearing loss. My research interests include molecular biology, computational modeling of biological systems, and epidemiology.


Ashley Kim

B.S., Research Scientist

Originally from southern California, I moved to Seattle to attend the University of Washington and graduated with a BS in Molecular, Cellular, Developmental Biology and a minor in Global Health. My research interests include molecular biology, global health, and the immunology and epidemiology of infectious disease.


Julia Rogers

M.P.H. Student, Research Scientist Assistant

Julia is an MPH student with the Department of Epidemiology at the University of Washington, with specialized interest in infectious diseases and vulnerable populations. Prior to moving to Seattle, she worked with global health organizations in rural Burkina Faso and Liberia for 5 years on community health worker programming and community-based case detection of HIV and TB. Julia is originally from Scituate, MA.


Jessica O’Hanlon

B.S., Research Scientist Assistant

Moving from northern California to Seattle to complete my undergraduate degree at the University of Washington, I graduated with a degree in Biology. While the beginning of my undergraduate research was primarily focused on bees and paleobiology topics, my interests have shift to environmental health and microbiology.


Kristen Huden

A.A.A.S., Research Technologist

Born and raised in Seattle, I recently earned my AAAS to become a Biotechnology Lab Specialist. From 2017-2018 I worked for UW research on a Wound Healing study for the Department of Defense. My current role in the Chu lab is Research Technologist. My work on the Seattle Flu Study includes specimen collection, data entry, and basic lab maintenance. I am interested in microbiology, epidemiology, and biomimicry.


Briana Del Rosario

Undergraduate Research Assistant

I am an undergraduate student (sophomore) at the University of Washington in Seattle. I intend to major in Microbiology, and subsequently earn a PhD in the molecular biology field to pursue my passion for disease research.
