Northwestern University Allergy and Immunology Research Program

Our Mission:

The overall aim of the Northwestern University Allergy and Immunology Research (NUAIR) Program is to train MD and PhD postdoctoral scientists in translational research, here defined as research of disease mechanisms that includes investigations in human subjects or human samples. The NUAIR program builds on our Allergy and Immunology Fellowship, which has a long history of excellence in clinical and academic training. Unified efforts of established investigators in our division with those from other divisions and departments have created a rich environment for translational research in the NUAIR program in which clinical and basic researchers, both faculty and trainees, collaborate and interact in weekly research and didactic activities. These collaborations have led to multidisciplinary translational research programs in several allergic diseases supported by well-equipped laboratories and a large number of research cores and facilities.

Under the NUAIR program, four MD and/or PhD postgraduate trainees per year will receive two years of research training. Each will work together with a clinical research mentor and a basic research mentor to study mechanisms of allergic and immunological diseases, including studies of human subjects or their derived samples. In addition to well- structured research training and didactic activities, strong mentoring and close monitoring of trainees’ performances based on milestones will ensure proper progress during training. Our retention plan includes support for trainees who remain in our division as junior faculty members after T32-supported training, while they seek external funding support. Senior faculty members in the Division of Allergy and Immunology have a strong record of mentoring trainees toward obtaining K awards and new R01 grants. We also offer programs to inspire medical students and residents to pursue careers in Allergy and Immunology. Taken together, our rapidly expanding and comprehensive Allergy and Immunology research environment provides state-of-the-art training to highly qualified MD, MD/PhD and PhD postdoctoral trainees. These trainees will conduct collaborative translational research in Allergy and Immunology, initiating research careers that will help solve a severe national need for academic leaders in this field.

 Program Eligibility and Application Process

Applications from postdoctoral fellows and clinical fellows are being accepted via our online application portal.

The NUAIR T32 Fellowship program is designed for MD and/or PhD trainees with an interest in advanced training in translational research in the field of Allergy and Immunology. Projects of trainees are those that have both clinical and laboratory components, and trainees have access to renowned mentors in both clinical and basic departments in order to develop a mentoring team with expertise in both realms to successfully complete projects and training. NUAIR is highly compliant with scientific, programmatic, and social initiatives of the NIAID and the NIH.

Program Eligibility

This program recruits post-graduate trainees with MD and/or PhD background who will propose research in allergy, asthma or immunology that includes investigation in human subjects or samples. Bench/animal-oriented research proposals should have a translational component, utilizing human subjects or human samples.

The NUAIR Program builds on the Allergy-Immunology Fellowship, which has a long history of excellence in clinical and academic training. Together with established investigators from other Divisions and Departments, we have a rich environment for translational research in the NUAIR program in which clinical and basic researchers, both faculty and trainees, collaborate and interact in weekly research and didactic activities. These collaborations have led to multidisciplinary translational research programs in several allergic diseases supported by well-equipped laboratories and a large number of research cores and facilities.  These trainees conduct collaborative translational research in Allergy-Immunology, initiating research careers that will help attenuate a severe national need for academic leaders in this field.

Important criteria for applicants:

  • Applicants should have a research project with a translational component and a primary mentor.  The projects usually involve a bench research mentor and a clinical research mentor though other arrangements are possible. The main mentor, who will work most closely with the applicant, must be a NUAIR T32 preceptor.  If a potential candidate has identified a mentor that qualifies to serve on NUAIR based on their NIH funding, mentoring success, and relevance to the Allergy-Immunology goals of NUAIR, we are happy to consider adding the mentor/applicant pair to the NUAIR team.
  • NIH T32 requires that the individual to be trained must be a citizen or a noncitizen national of the United States or have been lawfully admitted for permanent residence by training appointment date.
  • NRSA Support: No individual trainee may receive more than 5 years of aggregate Kirschstein-NRSA support at the predoctoral level and 3 years of aggregate Kirschstein-NRSA support at the postdoctoral level, including any combination of support from Kirschstein-NRSA institutional research training grants and individual fellowships.

For more information on NRSA eligibility requirements, see the NIH Grants Policy Statement on Kirschstein NRSAs.

Postdoctoral Appointments

The program appoints two trainees during the grant year for a two-year period.

Application Process and Deadlines

  • A two-year commitment is required, or an earlier departure will incur NIH-payback of the first year of support. 
  • Candidate must dedicate at least 75% of effort to research during T32 support.
  • Candidate must have a strong commitment to a research career.
  • Appointment is renewed yearly, and depending on adequate performance. 
  • In the initial phase of application, the candidate must submit a resume, an abstract of the research proposal, and must indicate the mentors and who will be the main T32 mentor/preceptor in our online portal.  Contact Lauren Rudolph, Research Administrator, with any questions regarding this process.

Allergy T32 Trainee Summaries:


Elisa Ochfeld, MD

Mentor: Bruce Tan, MD and Amer Khojah, MD 

Project Title: Using Kappa- Deleting Recombination Excision Circles (KREC) to Coding Joint Ratio to Estimate B Cell Bone Marrow Output in Patients with Immunodeficiency 

Research Description: Currently, there is no clinically useful way to reliably measure a person’s number of newly formed B cells. By quantifying the amount of KREC DNA and coding joint DNA, via real- time PCR (RT-PCR), one can estimate the number of B cell divisions in that population and ascertain the number of newly formed B cells. This measure could be clinically useful to assess severity of B cell immunodeficiencies, and to help predict risk of disease complication or susceptibility to infection.


Gayatri Patel, MD

Mentor: Anju Peters, MD and Joshua Wechsler, MD

Project Title: Real world clinical experience of biologics used for moderate to severe persistent asthma and chronic rhinosinusitis (CRS) at an academic tertiary care center

Research Description: This project is investigating clinical outcomes for newly approved biologics in patients with moderate to severe persistent asthma, including those with comorbid CRS. Her ultimate goal is to understand the efficacy of these different biologics and characterize the patient populations that benefit the most from these therapies.


Alexander Schneider, MD

Mentor: Bruce Tan, MD

Project Title: Association of sinonasal endotyping with subjective and objective response to medical and surgical therapy in patients with chronic rhinosinusitis (CRS)

Research Description: This project is investigating associations between the underlying sinonasal biochemical signature (endotype) and responses or lack thereof to medical and surgical therapy in CRS. We aim to determine what role endotypic information obtained cross-sectionally and longitudinally from a variety of nasal sub-sites can play in predicting treatment response, particularly in the realm of Type 2 inflammation.


Melissa Watts, MD

Mentor: Joshua Wechsler, MD

Project Title: Determining whether a common food additive contributes to the pathogenesis of eosinophilic esophagitis

Research Description: This project is evaluating whether a common food additive, carrageenan (CGN), contributes to the pathogenesis demonstrated in eosinophilic esophagitis by determining if CGN promotes epithelial barrier disruption or stimulates immune cells and/or pro-inflammatory mediators in EoE. Determining this possible role could potentially support a novel mechanism for the pathology of this chronic disease process as well as an opportunity for novel targeted therapies and dietary intervention.

What is a Payback Obligation?  How do I know if I incur one?
Any NRSA postdoctoral trainees or fellow incurs a payback obligation during their first year of support.  Pre-doctoral NRSA trainees do not incur a payback obligation.  Payback means that you will perform qualified research or teaching activities for a length of time equal to the period of NRSA support you received.  Receiving 12 months of postdoctoral training support obligates you to perform 12 months of qualified research or teaching activities as payback.  Only the first year of training incurs a payback obligation; the second year of training pays back the first year, with each month of qualifying payback activity paying back one month of NRSA support.  If you receive two full years of NRSA training, you will have completed your payback obligation.  In general, payback activity must involve at least 20 hours per week and be conducted over 12 consecutive months. Special exceptions to these requirements may be considered on a case-by-case basis.

Additional resources on Payback Obligations can be found on the NIH website, along with a separate payback FAQ.
