Principal Investigator

H. Benjamin Larman, Ph.D.

Originally from Portland, Maine, Ben earned his B.S. in Engineering Physics and Bioengineering from UC Berkeley in California. He went on to obtain his Ph.D. from Harvard-MIT’s Division of Health Sciences & Technology in the laboratory of Steve Elledge, developing new molecular assays such as “Phage ImmunoPrecipitation Sequencing” (PhIP-Seq), and “ParalleL Analysis of Translated ORFs” (PLATO). He next postdoc’ed with Pete Schultz at The Scripps Research Institute in La Jolla, CA, where he worked on high throughput screening methods, including “RNA Annealing, Selection and Ligation sequencing” (RASL-seq). In 2014, Ben started the Laboratory of Precision Immunology in the Pathology Department at Johns Hopkins, within the Division of Immunology. Here, his team develops and deploys massively multiplexed technologies to better understand human immune responses in health and disease states.


Laboratory: Joel Credle, Ph.D.

Joel earned his bachelor’s degree from Radford University and his Ph.D. from Georgetown University. Joel solved the first crystal structure of IRE1, a sensor of unfolded proteins within the ER while in the lab of Peter Walter at UC San Francisco. Joel’s Ph.D. involved elucidating the role of the unfolded protein response in the progression of Parkinson’s disease. In the Larman lab, Joel has developed oligonucleotide probe ligation based techniques to analyze RNA in clinical specimens Ligation in situ Hybridization (‘LISH’).s

Manju earned her B.S. in Biology and Chemistry at Osmania University in Hyderabad, India, followed by an M.S. in Biochemistry at Pune University in Pune, India and an M.S. in Biochemistry at Ohio State University. Manju runs the antibody profiling platform for the Larman lab.

Postdoctoral Fellows

Raja Venkataraman, Ph.D.

Raja grew up in the city of Chennai, India. He earned his Bachelor’s degree (Biosciences) and Master’s degree (Biotechnology) in India before he moved to the United States. Having always been interested in immune responses against viral pathogens, he investigated anti-viral signaling mechanisms focusing on the role of the Rig-I-like receptor (RLRs) LGP2 and how it contributes to interferon signaling at the University of Miami’s Miller School of Medicine. Raja earned his Ph.D studying host responses against the SARS coronavirus at the University of Maryland School of Medicine. In the Larman lab, he is investigating the heritability of anti-viral humoral responses using VirScan and developing novel applications for PhIP-Seq.

Anna Liebhoff, Ph.D.

After her Master’s in Computer Science in 2014, Anna worked at Airbus and then consulted EdTech startups. She then completed a Ph.D. in Systems Biology in Hamburg, Germany, where she became fascinated by the role of the microbiota in human health. Currently she holds a co-appointment in the Larman and Langmead Labs where she explores the gut-phage-immune axis via development of novel algorithms for antibody profiling applications.
