The Antibody Biology Unit aims to study antibody responses to infectious pathogens at the monoclonal level. Our major goals are 1) to develop new antibody therapeutics or prophylactics to combat infectious disease, 2) to study the antibody responses to immunization and infection at high resolution, and 3) to investigate the use of monoclonal antibodies as tools for immunogen design.

Joshua Tan, Ph.D.
Chief, Antibody Biology Unit
Earl Stadtman Investigator
Education:
Ph.D., University of Oxford, England
Dr. Tan received his Ph.D. from the University of Oxford, England. His Ph.D. work focused on the identification of unusual LAIR1-containing human monoclonal antibodies targeting antigens on Plasmodium falciparum-infected erythrocytes. After his Ph.D., he was awarded a Sir Henry Wellcome Postdoctoral Fellowship to continue his work on human monoclonal antibodies against human-infecting pathogens...
Andrew J.R. Cooper, Ph.D.
Visiting Postdoctoral Fellow
Education:
Ph.D., Immunology, University of Dublin, Trinity College
Cherrelle Dacon, Ph.D.
Visiting Postdoctoral Fellow, Malaria Research Program
Education:
D.Phil., Infection, Immunology and Translational Medicine, University of Oxford
Cherrelle’s work in the Antibody Biology Unit centers on the discovery and characterization of human monoclonal antibodies. Her current research focuses are (I) the identification of novel mAb targets on P. falciparum sporozoites and (II) the characterization of broadly neutralizing antibodies against infectious viruses. Ultimately, this work will guide immunogen design and the development of...
Adriano Franco-Casín, Ph.D.
Visiting Postdoctoral Fellow
Education:
Ph.D., Molecular Microbiology and Immunology, Johns Hopkins University
The main goal of Adriano’s research is to identify next-generation monoclonal antibody therapeutics. A similar approach is being used to identify new mAbs that target P. falciparum sporozoite CSP for clinical development. His main research interests include infectious diseases and antibody and immune memory development in response to pathogens.
Shi-Hsia Hwa, Ph.D.
Visiting Postdoctoral Fellow
Education:
Ph.D., Infection and Immunity, University College London
Shi-Hsia’s project aims to discover new B cell antigens in Mycobacterium tuberculosis (Mtb) as well as functionally protective human monoclonal antibodies, using high-throughput, antigen-agnostic methods to isolate anti-Mtb antibodies from tuberculosis (TB)-exposed donors. While Mtb has a large number of protein, polysaccharide, and lipoglycan antigens that elicit specific antibodies, only a...
Jake E. Kritzberg, B.A.
Laboratory Manager
Education:

Jake supports and assists ongoing research projects focusing on human monoclonal antibodies to pathogenic viruses, malaria, and tuberculosis.
Mariah Lofgren, B.A.
Ph.D. Student, NIH Oxford-Cambridge Scholars Program
Education:
B.A., Sarah Lawrence College
Mariah will take an antigen-agnostic approach to discover antibodies in conjunction with structural biology techniques to identify sites of vulnerability on P. falciparum merozoites. With this work, she hopes to discover potential antibody and immunogen candidates for blood-stage malaria as well as help answer parasite biology questions. She’s excited about this project as it combines her...
Hasmik Manukyan, M.Sc.
Scientist
Education:
M.Sc., Environmental Chemistry, Yerevan State University
Hasmik’s research interests are in PCR and NGS methods development and validation, as well as implementing various molecular biology techniques for diverse research purposes. At the Antibody Biology Unit, she is working to develop an NGS library preparation protocol for single-sorted B cells and B cell lines expressing target antibodies to assess B cell activation by candidate immunogens.
Samantha L. Petros B.Sc.
Biologist
Education:
B.Sc., Translational Life Sciences and Technologies, University of Maryland, Baltimore County
In the Antibody Biology Unit, Samantha contributes to the advancement of malaria research by dissecting and collecting sporozoites from malaria-infected mosquitos. Her work involves research into malaria parasite development, utilizing microscopy techniques and cell culture methods. Samantha is committed to advancing infectious disease research and addressing global health challenges.
Courtney A. Tucker, B.Sc.
Graduate Student
Education:
B.Sc., Biology, American University
The focus of Courtney’s research project is to study antibodies that reduce or prevent the clinical manifestations associated with malaria infection using an antigen-agnostic approach to target asexual blood-stage malaria. Additionally, she is interested in identifying transmission-blocking antibodies capable of blocking the sexual reproductive cycle and parasite development in the mosquito vector...
Weizhi William Zhong, M.Sc.
Scientist
Education:
M.Sc., Biochemistry and Molecular Biology, Johns Hopkins University
At the Antibody Biology Unit, William is dedicating his efforts to the advancement of antibody engineering through the strategic utilization of cell surface display technologies. His work is focused on improving the affinity and avidity of antibodies, employing these biotechnological methods to pave the way for groundbreaking developments in therapeutic interventions and antibody research.
