Summary
The Dean Lab research involves in vitro and integrated bioinformatic approaches along with studies of human populations to address host-pathogen interactions, including bacterial genomics, host immune responses, antimicrobial resistance and multi-omics analyses of microbiomes. Disease protection and pathogenesis related to the obligate intracellular bacterium Chlamydia trachomatis are a key focus. The Dean lab also studies the evolution of zoonotic chlamydial species. The Lab’s international research involves the epidemiology and molecular epidemiology of and risk factors for trachoma and sexually transmitted disease populations in Nepal, India, Ecuador, Thailand, Vietnam and Fiji. In addition, her group collaborates with Bay Area biotech start-ups to develop vaccines and rapid inexpensive point-of-care diagnostics for C. trachomatis and Neisseria gonorrhoeae for global deployment. Professor Dean has a track record of over 34 years of uninterrupted R01 funding from the National Institutes of Health in addition to grants from the U.S. Centers for Disease Control, World Health Organization and the National Science Foundation. She is a Fellow of the American Academy of Microbiology and has mentored over 170 national and international undergraduate, graduate and medical students, and postdoctoral fellows who have gone on to university professorships and positions at institutes of health and centers for disease control throughout the world. In 2018, she was awarded the Influential Alumni Award for Significant Contributions in the Field of Public Health by the UC Berkeley School of Public Health and, in 2021, became a UCSF Diversity, Equity and Inclusion Champion. She remains an advocate for ocular and reproductive health among vulnerable and neglected populations worldwide.
​​Olusola (Shola) Olagoke, PhD
Postdoctoral Fellow
Shola is a microbiologist with expertise in microbial genomics, host–pathogen interactions, and multi-omics data analysis. He has an MSc in animal and veterinary sciences and a PhD in Microbiology. His research is focused on applying and creating integrative bioinformatics tools to explore the molecular mechanisms of chlamydial pathogenesis and host-pathogen interactions related to sexually transmitted infections and trachoma — the leading infectious cause of blindness in the world today.
Augusta Uwamanzu-nna, BS
MD/PhD student
Augusta has a BS in Engineering Sciences with a focus in Bioengineering from Harvard University and is currently a UCSF MD/PhD student in the lab. Her research focuses on understanding ocular microbiomes in trachoma populations in the Global South through defining community state types using various clustering algorithms. She also aims to develop predictive models for infection risk and trachomatous disease.
Neeraja Sripada, BA
Post Bac Researcher
Neeraja graduated May 2025 from UC Berkeley with a BA with Honors in Molecular and Cell Biology and a minor in Bioengineering. She completed her Honor’s Thesis in the lab and is the recipient of the MCB Departmental Spencer W. Brown Award in Genetics, Genomics, Evolution, and Development. Her research focus has been to characterize the host immune response to rectal C. trachomatis infections among females residing in Fiji and the role that C. trachomatis genomic strain types have on immunity and persistent infections, integrating comparative and functional genomics into the analyses.
Seongwon Chung,
dual BAs
Staff Research Associate
Seongwon graduated May 2025 from UC Berkeley with a BA with Honors in Molecular and Cell Biology and a BA in Public Health. He completed his Honor’s Thesis in the lab and is the recipient of the MCB Departmental Award for Academic Excellence in Immunology. His research focuses on defining the host immune response among trachoma populations and the role that the microbial composition of the microbiome might play in enhancing disease pathogenesis.
