Allergy/Immunology Fellowship

Heather Lehman and Parteet Sandhu.

Program director Heather Lehman, MD, with fellow Parteet Sandhu, MD.

Our two-year fellowship program combines participating faculty from the departments of Medicine and Pediatrics.

Our cross-departmental collaboration allows for strong clinical training and excellent research opportunities spanning the broad spectrum of allergic and immunologic medicine (asthma, food allergy, atopic dermatitis, primary immunodeficiencies and other allergic conditions).

Our two-year fellowship is fully integrated in both the Department of Medicine and the Department of Pediatrics, with significant cross-training in pediatric and adult allergy and clinical immunology.

You will gain valuable clinical and research experience in the fields of allergy and clinical immunology. We provide all fellows with opportunities to apply immunologic theories, principles and techniques to the investigation, diagnosis and treatment of a broad spectrum of allergic and immunologic diseases.

Our areas of clinical strength include: asthma, allergic disorders, drug reactions, urticaria, primary immunodeficiency diseases, food allergy and autoimmune diseases.


Educational features of our training program include:

  • orientation lecture series for incoming fellows (weekly in July/August)
  • didactic asthma/allergy conferences (weekly during academic year)
  • Allergy/Immunology Journal Club (monthly)
  • Allergy/Immunology Case Conference (monthly)
  • Basic Immunology course (weekly)
  • Board Review Jeopardy (monthly during academic year)
  • Department of Medicine grand round series (weekly)
  • anaphylaxis simulation training (yearly)
  • Annual Weed Walk
  • Buffalo Allergy Society meeting (monthly)
  • Laboratory Technique course (6 weeks biannually)

The Immunobiology Clinical Laboratory supports our laboratory techniques wet-lab course for allergy/immunology fellows, instructing fellows on the fundamentals of diagnostic immunology assays used in clinical practice.

Clinical Service

Clinical education includes direct patient contact in both the outpatient and inpatient settings, clinical care conferences and record reviews. Fellows provide inpatient consultations to the medical and pediatric services for allergic and immunologically-mediated disorders. You will also participate in the following outpatient clinical activities:

  • Monday a.m.: BGMC Adult Allergy/Immunology Continuity Clinic
  • Monday p.m.: BGMC Adult Autoimmune/Vasculitis Clinic or OCH Pediatric Rheumatology Clinic
  • Tuesday a.m.: VA Adult Allergy/Immunology Clinic or UBMD Pediatric Allergy/Immunology Clinic at University Commons
  • Tuesday p.m.: UBMD Pediatric Allergy/Immunology Continuity Clinic
  • Wednesday a.m.: VA Adult Allergy/Immunology Clinic or OCH IVIG Infusion Service
  • Friday a.m.: UBMD Pediatric Allergy/Immunology Procedures Clinic

You will train in diverse clinical sites, including Buffalo General Medical Center, Oishei Children's Hospital, UBMD Pediatrics outpatient centers, and VA Medical Center.


Our faculty is involved in a number of research projects, in both clinical and basic immunology. You will develop and complete your own research project(s). We provide our fellows with a structured research experience sufficient to result in an understanding of the basic principles of study design, performance, analysis and reporting of the assigned area of investigation. Some of these areas include/have included:

  • role of B cells in Sjogren syndrome
  • role of mycoplasma infection in eosinophilic esophagitis
  • development of an anaphylaxis simulation program
  • evaluation of specific pneumococcal antibodies in PIDD patients receiving IVIG
  • effect of a room hepafiltration system on pediatric asthma
  • assessment of humoral immunity in children with Down syndrome
  • utility of text message medication reminders for adolescent asthmatics
  • identification of SNPs in food allergic children


Our comprehensive fellowship training program in allergy/immunology is fully accredited by the Accreditation Council for Graduate Medical Education (ACGME) and the American Board of Allergy Immunology (ABAI).

To Apply

The postdoctoral education prerequisite is three years of general pediatric residency training. Candidates should apply through ERAS and enter the allergy/immunology match through NRMP.
