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 then 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). Ben started his own laboratory in the Pathology Department at Johns Hopkins in 2014, within the Division of Immunology. Here, our team develops and deploys massively multiplexed technologies to better understand human immune responses in sickness and in health.

Postdoctoral Fellows

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 a new technique for analyzing RNA in clinical FFPE tissue specimens, which is called Ligation in situ Hybridization (‘LISH’).s

Gabriel Roman, Ph.D.

IMG_7466Gabriel began studying chemistry at the University of Puerto Rico and finished his B.S. at Baylor University. Working with professor Neil Marsh, he earned his Ph.D. from the University of Michigan studying how a particular class of enzymes is able generate highly-reactive radical intermediates and direct them toward productive catalysis (Biochemistry 53, 169-177). Currently a postdoctoral fellow in the Larman lab, Gabriel is developing post-translational modification-based applications for Phage ImmunoPrecipitation sequencing (PhIP-seq).

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.
