Autumn Breaud, M.S., Clinical Laboratory Manager

Autumn earned her B.S. in biology from The University of Texas and a M.S. in Biotechnology (2008) and an M.S. in Environmental Science and Policy (2013) from The Johns Hopkins University. During her graduate coursework, Autumn, under the direction of Dr. William Clarke, has helped to build the mass spectrometry section of the Johns Hopkins University Clinical Chemistry Reference Laboratory. Autumn specializes in development of LC-MS/MS assays for implementation into the Reference Laboratory’s clinical and research testing menus.

Samantha Olszewski, Administrative Coordinator

Samantha came to Johns Hopkins in 2010 as the Budget Assistant in the Physiology department. In 2017, she moved to the Pathology Department, Clinical Chemistry Division as the Administrative Coordinator. She graduated from Towson University in 2010 with a B.S. in English.

Lijun Chen, Ph.D., Research Technologist

Dr. Chen received her Ph.D degree in Biophysics from Nankai University, China in 2008. After graduation, Dr. Chen joined the Department of Biochemistry at the Institute of Biophysics, at the Chinese Academy of Sciences as a research assistant from 2008 to 2011. In 2012, Dr. Chen joined the Center for Biomarker Discovery and Translation as a research technologist, working on the sample preparation and HPLC fractionation for LC-MS analysis.

Naseruddin Hoti, Ph.D., Senior Research Specialist

Dr. Hoti earned his Ph.D. in Molecular Biology and Biochemitry from the University of Science and Technology of China in 2004. Upon completion of his Ph.D., Dr. Hoti became a research fellow at the Max Planck Institute of Molecular Cell Biology and Genetics before joining the Brady Urological Institute at the Johns Hopkins School of Medicine in 2004. Dr. Hoti earned a faculty appointment at the Brady Urological Institute in 2010. 

Michael Schnaubelt, B. Sc., Research Data Analyst

Michael earned his B.Sc. in Physics from the University of Maryland, Baltimore County in 2011.  He joined the Center for Biomarker Discovery in January 2015 as a research data analyst.  He assists his colleagues on various projects in developing computational methods for improved and faster data analysis.

Jin Song, M.D., Ph.D., Research Program Manager

Dr. Song received his M.D. from Third Military Medical University and his Ph.D. in Ophthalmology from West China University of Medical Sciences. He also earned a M.S. degree in Biomedical Engineering from Louisiana Tech University. He did his postdoctoral fellowships in Cancer Research at both Louisiana State University and Johns Hopkins University. From 2004 to 2009, Dr. Song had been working in identification and characterization of tumor-associated markers for early detection and diagnosis of cancer at the Center for Biomarker Discovery. His research focuses on using high-throughput genomic and proteomic approaches to identify novel markers and their interacting partners; using independent sample sources and platforms to further evaluate their clinical utility; studying cellular functions of markers to better understand the role they play in development and progression of cancer; developing new immunoassays on these markers for the clinical applications. After five years of working in development and application of high-throughput genetic and epigenetic approaches to detect sequence alterations and epigenetic markers related to retinal degenerations at both NEI/NIH and Wilmer Eye Institute, Dr. Song rejoined the Center in 2014 to apply his expertise to develop new multiplex immunoassays of disease–associated markers for clinical applications.             

Sabitha Schools, B.S., Research Specialist

Sabitha Schools received her B.S. from Morgan State University in 2002. She is part of the University reference Chemistry lab and assists with routine data verification and quality to ensure data integrity of clinical and research protocols. She also serves as the clinical coordinator of the toxicology core of the HIV Prevention and Trials Network (HPTN). She currently is pursuing her master’s degree in Bioinformatics, with a focus on protein structure and synthesis.
