Projects and funding availability come and go but we are always on the look out for passionate undergraduates, and graduate students, and postdocs. We'd be happy to connect with you!
About Purdue:

Purdue University is a worldclass land grant-university located in Tippecanoe County, Indiana, USA dedicated to learning, discovery, and engagement. The university is consistently ranked among the leading research institutions in the country. Purdue is one hour from Indianapolis and two hours from Chicago.

Purdue University is an affirmative action, equal opportunity employer and the Linnes lab is an inclusive lab. All individuals, including Black, Ingenious, LatinX, people of color, women, LGBTQ+, individuals with disabilities, and veterans are encouraged to apply.


PhD students

We typically recruit 1-2 students each year. Please apply to Purdue Graduate School with Biomedical Engineering as your major (check Purdue Biomedical Engineering Admissions for important dates and recruiting events) and be sure to list your interest in our lab in your application. Also, feel free to email Dr. Linnes about why you are interested in the lab along with your resume/CV.


Postdocs (available Jan 2021) – Point-of-care diagnostic design for manufacturing

Project Description:

The Linnes Laboratory at Purdue University has an immediate openings for full-time Post Doctoral Research Assistants to design and translate paper-based point-of-care diagnostic devices emanating from projects sponsored by the NIH and Gordon and Betty Moore Foundation. These projects will enable the design and translation of paper-based diagnostic platforms for low-cost and robust device manufacturing at scale. The platforms are based on colorimetric immunoassays and isothermal nucleic acid amplification-based detection.

The 2 postdoctoral fellows involved in the projects will 1) perform applied experimental research to design, tune, scale, and evaluate these rapid point-of-care testing platforms at the cut sheet and roll-to-roll manufacturing scales and 2) develop novel protein and nucleic acid assays for emerging and existing infectious diseases (current funding includes COVID-19, HIV, cervical cancer, among others). Postdocs will develop critical design parameters and perform molecular assay development, reagent storage, ink-jet printing, and metrology. They will have access to Purdue’s roll-to-roll manufacturing at the state-of-the-art Birck Nanotechnology Facility for fabrication as well as rapid prototyping equipment within the Linnes lab itself.

Activities may involve but are not limited to paper-fluidic device design, process control target development, low-volume cut-sheet production, and medium volume roll-to-roll manufacturing, and immunoassay and isothermal amplification and reagent storage optimization. Postdocs will be expected to assist with supervision and mentorship of graduate and undergraduate research assistants and actively publish results of their research in peer-reviews journals and conference proceedings. Further, the resulting platforms will be designed through cross-disciplinary collaborations with multiple stakeholders including community health workers, contract manufacturers, patients, and other health services.

Postdoc Qualifications:

Applicants should have a Ph.D. degree in relevant mechanical biomedical/bioengineering, materials science, biochemistry, immunology, molecular biology or related fields. Prior experience in microfluidics/paper-fluidics, inkjet printing, bioassay development, lateral flow immunoassays, roll-to-roll manufacturing, human-centered design and/or point-of-care diagnostic device development is required. Strong oral and written communication skills are necessary as is previous experience mentoring undergraduate and graduate students and engaging with community stakeholders. The candidate should be proactive and organized, with the ambition and commitment to excel in a highly cooperative, interdisciplinary, entrepreneurial, and productive translational research environment.

Application Information:

Applicants should contact Prof. Jacqueline Linnes (jlinnes@purdue.edu) with their cover letter and CV to apply. Screening of applications will begin immediately and will continue until the position is filled.


Postdoctoral Fellow Position available – Point-of-care cervical cancer diagnostic

Project Description

Although cervical cancer is an easily curable disease if detected early, it continues to claim the lives of hundreds of thousands of women worldwide. Due to disparities in healthcare access, women in rural America and other low-resource settings worldwide are twice as likely to die from cervical cancer as their urban and high-resource counterparts.

This research will develop a paper-based sample-to-answer test that provides sensitive and specific detection of high-risk pre-cancer and invasive cervical cancer at the point-of-care. The project will translate the detection of recently identified dysregulated protein biomarkers from centralized laboratory assays to rapid paper-fluidic tests. The postdoctoral fellow involved in the project will perform applied research to develop and evaluate this rapid, point-of-care test for cervical cancer screening in low-resource settings. Activities could involve but are not limited to immunoassay design, biomarker screening, sample preparation, micro- and paper-fluidic device design and manufacturing for multiplexed sample processing. Further, the assay must be designed in collaboration with the end users, community health workers, clinicians and manufacturers. Implementation of this test in the field will ultimately unable healthcare providers in under-resourced settings to obtain relevant clinical insights, including cervical cancer risk stratification, and enable same-visit treatment of high-risk cervical lesions.  

Postdoc Qualifications

Applicants should have a Ph.D. degree in relevant biomedical engineering, biochemistry, molecular biology, or related fields. Prior experience in bioassay development, lateral flow immunoassays, or point-of-care colorimetric device development is required. A Masters in Public Health, graduate certificate in global health, and/or prior experience with human-centered design are encouraged. Strong oral and written communication skills are required. The candidate should be highly motivated with the ambition and commitment to excel in a highly cooperative, interdisciplinary, and productive translational research environment.

Application Information:

Applicants should contact Prof. Jacqueline Linnes (jlinnes@purdue.edu) with their cover letter and CV to apply. Screening of applications will begin immediately and will continue until the position is filled.
