Postdoctoral Fellow in Infectious Disease Diagnostic Technologies Faculty

The Institute for Nano Bio Technology  (INBT) and Department of Mechanical Engineering at Johns Hopkins University invite applications for a Postdoctoral Fellow position in the BioMEMS Laboratory led by Tza-Huei "Jeff" Wang (For information about the lab, see: (Use the "Apply for this Job" box below).). We seek a highly motivated, independent researcher to lead scientific efforts and technology development on microfluidic-based in vitro diagnostics for bloodstream infections under an NIH‑funded project.

• Independently lead and collaborate on research projects spanning human infectious diseases, especially bacterial bloodstream infections and antimicrobial resistance.
• Design, execute, and troubleshoot experiments; develop and validate nucleic acid and microbiological assays for diagnostics.
• Contribute to the development, prototyping, and testing of microfluidic devices and related workflows.
• Help advance technologies toward clinical laboratory implementation and regulatory submissions (e.g., FDA EUA/510(k)).
• Mentor and supervise graduate and undergraduate students.
• Prepare progress reports and present results to collaborators and sponsors.
• Publish findings in peer‑reviewed journals.
• Contribute to competitive grant and contract proposals to federal agencies (e.g., NIH).
• Develop, implement, and maintain laboratory standard operating procedures and biosafety practices at the BSL‑2 level.

• Ph.D. in microbiology, infectious diseases, biomedical engineering, bioengineering, or a closely related discipline.
• Demonstrated track record in the in vitro diagnosis of human and/or animal infectious diseases.
• Experience working in BSL‑2 laboratories, including safe handling of blood samples and infectious materials.
• Expertise in microbiological assays (e.g., culture, antimicrobial susceptibility testing).
• Expertise in molecular diagnostics (e.g., PCR, digital PCR, LAMP, RPA, CRISPR‑based assays).
• Experience designing, fabricating, and testing microfluidic devices and platforms (e.g., cleanroom microfabrication, laser cutting, thermoforming, 3D printing) and in microscopy‑based characterization.
• Proficiency in data analysis and computational tools (e.g., MATLAB, Python, or equivalent).
• Strong written and oral communication skills and a record of publishing and presenting research.
