Dr. Hiromi Muramatsu received his B.S. from the Tokyo University of Science in Tokyo, Japan in Chemistry in 1989. He earned his doctorate in Veterinary Science from the Nippon Veterinary and Life Sciences University in Tokyo, Japan in 2004 under the tutelage of Professor Kazuaki Takahashi. His thesis work focused on the role of superoxide anions during experimental cerebral ischemia using an MCA technique in rats. Dr. Muramatsu was a researcher at the Nippon Medical School in the laboratory of Professor Katayama from 1983-2001. In this role he became an expert in generating and characterizing focal ischemia in rats. He joined the laboratory of Dr. Frank Welsh in 2001 to continue his research in ischemia. He was an NRSA Post doc from 2004-2005 and trained under Dr. Katalin Kariko in molecular biology techniques focusing on RNA therapies. He worked with Drs. Kariko and Weissman through 2013, studying the effect of non-immunogenic mRNA on erythropoietin levels in mice. He joined BioNTech SE in 2013 with Dr. Katalin Kariko to starting up the mRNA Division, where they continued the work initiated at the University of Pennsylvania. He returned to the University of Pennsylvania in the laboratory of Dr. Drew Weissman in 2016. Working with Drs. Weissman and Norbert Pardi, his work focused on protein replacement therapies and mRNA vaccines.

Research Specialist
he/him/his
Adam Sirusas received his B.A. in Biomathematics from Rutgers University, New Brunswick in May 2020. While completing his degree, Adam helped investigate the molecular ecology of bats regarding the fungal pathogen P. Destructans, as well as how climate change affects gene expression in coral.
After a handful of temporary COVID-19 diagnostic positions, Adam joined the Weissman Lab in 2021 under the supervision of Drs. Mohamad-Gabriel Alameh and Istvan Tombacz. He supported his colleagues’ research on mRNA vaccine technology by producing in vitro-transcribed mRNA and performing a variety of assays. In the near future, Adam plans to attend graduate school and work on interdisciplinary research problems that incorporate his diverse academic background.

Research Specialist
he/him/his
Ousamah Soliman received his Bachelor’s degree in Biomedical Engineering, from Polytechnique Montreal in 2015. During his time as an undergraduate student, he completed three internships in a research laboratory focusing on biomaterials for gene delivery. Under the supervision of Professors Michael D. Buschmann and Marc Lavertu, he led experimental projects with the aim of optimizing the production parameters of chitosan based polyelectrolyte complexes. Within that group, he had contributed to the development and validation of a fully automated production system for sterile large scale and robust assembly of polymeric nanoparticles encapsulating different kinds of therapeutic RNA and DNA. Furthermore, he received his Master’s Degree within that same research group. The Master’s research project involved an exhaustive screening of polyelectrolyte complexes designed for mRNA delivery, with the aim of systematically evaluating the influence of macromolecular properties of chitosan and hyaluronic acid, and components stoichiometry on the physicochemical properties of the nanoparticles and their in vitro transfection efficiency. He had joined the Weissman Lab as a research specialist and worked under the supervision of Dr. Mohamad-Gabriel Alameh. Mr. Soliman has produced over 600 mg of pure mRNA used in several vaccine research & development projects. He has a strong interest in optimization of in-vitro synthesized nucleoside-modified mRNA.
