Haley E. Adcox, PhD
Postdoctoral Research Associate
Department of Microbiology, Immunology & Cancer (MIC)
University of Virginia
Email: dmg8ny@virginia.edu
Haley acquired her PhD at Virginia Commonwealth University under Dr. Jason Carlyon primarily investigating two different effector proteins and how they modulate the immune response for the benefit of the obligate intracellular bacterium, Orientia tsutsugamushi, the causative agent of Scrub Typhus.
Due to the lack of currently developed genetic tools for chromosomal manipulation of O. tsutsugamushi and the limited lab options for utilizing in vivo model systems, Haley decided to leave the Rickettsiales world and jump into the more competitive field of Chlamydia trachomatis. Although still a very difficult task, the Chlamydia field is on the leading edge for utilizing and developing genetic tools for obligate bacteria that have undergone reductive evolution.
In the summer of 2023, Haley joined the lab of Dr. Isabelle Derré to study C. trachomatis pathogenesis. While still maintaining an interest in host-pathogen interactions, a lot of her work now heavily focuses on the bacteria and how it regulates conversion from an infectious to a non-infectious but replicating form early in its developmental cycle.

LinkedIn Profile: https://www.linkedin.com/in/daviddelgadod/
David is a microbiologist and biotechnologist with a strong interest in sexually transmitted infections (STIs), particularly those affecting underserved populations. After earning a Bachelor’s degree in Biotechnology Engineering in Peru, he moved to Australia, where he completed a Master of Biotechnology at the University of Melbourne and a PhD in Microbiology and Immunology at the Burnet Institute and Monash University. His doctoral research explored how vaginal microbiota-derived metabolites influence immune responses and epithelial barrier integrity in the female reproductive tract, and how these changes affect susceptibility to HIV, leading to three publications.
During his PhD, David was awarded the prestigious MBio Postgraduate Discovery Scholarship from Monash University, which funded his tuition and stipend throughout his studies. He also received travel grants from HIV Research for Prevention (HIVR4P) and the Burnet Institute’s Pauline Speedy Travel Award, allowing him to present at HIVR4P 2018 in Madrid, Spain, and the 2020 Australasian Virology Society (AVS) meeting in Queenstown, New Zealand.
Following his PhD, David spent four years in the biotechnology industry, where he developed innovative, multiplex point-of-care diagnostic tools for infectious diseases. This experience sharpened his skills in product development and translational research, reinforcing his ability to bridge scientific discovery with real-world application.
Currently, David is a postdoctoral researcher at the University of Virginia in the laboratory of Dr. Isabelle Derré. He is leading the development of a novel 3D biomimetic model of the human cervix to study Chlamydia trachomatis infection in a physiologically relevant context. His interdisciplinary approach integrates microbiology, cell biology, immunology, and bioengineering to recreate the complex cervical environment—including cellular components, mucus, microbiota, and sex hormones. This platform aims to uncover key microbial and host factors driving STI acquisition and progression, and to support the evaluation of new preventive and therapeutic strategies.

Songyu received her PhD from Ohio State University, where she studied the pathogenic mechanisms of actin-targeting bacterial ADP-ribosylating toxins. She analyzed the behavior of ADP-ribosylating toxins secreted from various pathogens, including Photorhabdus luminescens and Salmonella enterica, under more physiologically relevant conditions in the presence of multiple host regulators. Impressed by how bacterial toxins efficiently manipulate the complex actin cytoskeleton, she joined the Agaisse lab in the MIC Department in December 2024 to investigate the interactions between actin-binding proteins and virulence effectors of Shigella flexneri.

Chandra Shekhar Misra, Ph.D., is an engineer (by Degree) turned biologist, as his interest wavered from once being a part-time environmental biotechnologist to what he now prefers to call himself: a fundamental biologist. After a brief stint in corporate world after his Bachelor´s, he returned to academia and has been there ever since.
His initial experiences piqued his curiosity to work with these seemingly inanimate life forms which not only feed us but also possess one of the most interesting physiologies for coping with different environmental factors. Yes, we’re talking about plants. He finished his PhD in Plant sciences from Portugal before moving to US for his postdoc. He did his first postdoc at UMASS Chan Medical school, working on understanding the molecular mechanism behind transcriptional buffering in budding yeast.
He joined Cliffe lab at UVA in April 2025 to work on something more translational- an area he has been eager to explore for some time now. Currently, he is focussed on understanding how host cells regulate the HSV-1 viral gene silencing by manipulating its chromatin structure.

Steven is a cellular microbiologist passionate about uncovering the mechanisms used by intracellular bacteria to infect their hosts and cause disease. He discovered his interest in host-pathogen interactions during his MSc at the University of Paris Diderot and Pasteur Institute (Paris, France), where he studied the intracellular bacterium Listeria monocytogenes. He earned his PhD from the University of Poitiers (Poitiers, France), investigating the physiology of the free-living amoeba Acanthamoeba castellanii during encystment and its interaction with the intracellular bacterium Legionella pneumophila.
In October 2020, Steven joined the Agaisse lab at the University of Virginia to study the host factors facilitating the cell-to-cell spread of Shigella flexneri. He believes that a deeper understanding of the mechanisms involved in pathogenesis is essential for combating the alarming rise of multi-drug-resistant strains by targeting host factors to disrupt bacterial pathogenesis.

She also spent five years at the Noguchi Memorial Institute for Medical Research, where she investigated the transmission dynamics of Mycobacterium ulcerans and the molecular epidemiology of diarrheal diseases.
During her PhD, Caitlin collaborated with Dr. Brady Spencer to explore the relationship between GBS prophages and the Type VII secretion system—work that resulted in a co-authored publication. This experience deepened her interest in secreted bacterial effectors and microbial interactions. In September 2024, she joined the Spencer Lab, where she is currently investigating the mechanisms of a toxin secreted by the Type VII secretion system in GBS.

University of Virginia
Email: krt9kk@virginia.edu
Xian completed her graduate studies at Fudan University in Shanghai, where she gained valuable experience in both human and mouse vaccine development, adjuvant screening, and evaluation of immune responses post vaccination. In 2017, she joined the Mayo Clinic as a postdoctoral fellow, focusing on metabolic regulation of immune cell development and function, as well as immune metabolism in autoimmune diseases.
Driven by a strong interest in cancer immunology, she later joined Dr. Hui Zong’s laboratory at the University of Virginia (UVA) to investigate immune surveillance against pre-cancerous cells during the premalignant stage of breast cancer. The Zong lab has developed a triple-negative breast cancer (TNBC) mouse model using stochastic Brca1–Trp53 knockout with Mosaic Analysis with Double Markers (MADM) (Zong et al., Cell, 2005; Zeng et al., Dis. Model. Mech., 2023) in active mammary progenitors. Using multiple spatial profiling tools, she discovered that immune surveillance—particularly T and B cell–driven immune aggregate formation—plays a critical role in restraining premalignant progression long before tumor formation.
