Postdoctoral Scholar in Microfluidic Disease Diagnostic Technologies

The Institute for NanoBioTechnology (INBT) and Department of Mechanical Engineering at Johns Hopkins University invite applications for a Postdoctoral Scholar position in the BioMEMS Laboratory led by Tza-Huei “Jeff” Wang (For information about the lab, see: https://me.jhu.edu/thwang/ ). We seek a highly motivated, independent researcher to lead scientific efforts and technology development on microfluidic-based in vitro diagnostic technologies toward infectious disease and cancer detection…

applications.

Key Responsibilities

Independently lead and collaborate on research projects aimed at detecting human diseases including infectious diseases (especially bacterial bloodstream infections and antimicrobial resistance) and cancer (especially lung and ovarian).
Design, execute, and troubleshoot experiments focused on development and testing of microfluidic devices and related workflows, as well as development and validation of nucleic acid-based diagnostic assays.
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).

Minimum Qualifications

Ph.D. in biomedical engineering, bioengineering, mechanical engineering, or a closely related discipline.
Demonstrated track record in microfluidics and in vitro diagnosis of human diseases.
Expertise in designing, fabricating, and testing microfluidic devices and platforms (e.g., cleanroom microfabrication, laser cutting, thermoforming, 3D printing) and in microscopy-based characterization.
Expertise in molecular diagnostics, especially for nucleic acid targets (e.g., PCR, digital PCR, methylation-specific PCR, LAMP, RPA, CRISPR‑based assays).
Expertise in either microbiological assays (e.g., culture, antimicrobial susceptibility testing) or cancer detection assays (e.g., liquid biopsy handling, nucleic acid extraction).
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.
Demonstrated ability to mentor and lead junior researchers and work effectively in multidisciplinary teams.

Preferred Qualifications (Not Required)

2 or fewer years of postdoctoral experience.
Experience in safe handling of clinical specimens (e.g., blood and plasma) and infectious materials (e.g., bacteria) in BSL‑2 laboratories environment.
Experience in developing, implementing, and maintaining laboratory standard operating procedures and biosafety practices at the BSL‑2 level.
Prior experience with clinical microbiology workflows and familiarity with regulatory pathways (e.g., FDA EUA/510(k)) for diagnostic devices. Experience with technology translation, commercialization, or interactions with industry partners.

Salary and Benefits

Salary will be commensurate with qualifications and experience, consistent with NIH FY2026 standards (https://grants.nih.gov/grants/guide/notice-files/NOT-OD-26-044.html). For information on benefits, visit: https://engineering.jhu.edu/studentaffairs/postdoctoral-fellows/services-and-benefits/.
