Appointment Type Postdoctoral Fellow

Department IUSM - Microbiology & Immunology

Campus IU School of Medicine Indianapolis

Position Summary

Position Title: Postdoctoral Fellow in Peptide Chemistry and Cancer Immunotherapy The Peptide Laboratory at the Indiana University School of Medicine is seeking an outstanding and highly motivated Postdoctoral Fellow to join a multidisciplinary research program focused on the discovery and translation of next-generation peptide-based cancer immunotherapies. The laboratory has pioneered B-cell epitope peptide vaccines targeting immune checkpoint molecules and oncogenic growth factor receptors and is advancing novel multivalent and multispecific vaccine platforms toward clinical translation. The successful candidate will lead innovative projects integrating peptide chemistry, structural immunology, cancer biology, and translational immunotherapy. This position offers the opportunity to work in a highly collaborative environment with access to state-of-the-art chemistry, proteomics, immunology, and animal research cores while contributing to projects with strong publication, patent, and clinical translation potential. Research Focus

Current research programs include:

Therapeutic peptide vaccines targeting PD-1, CTLA-4, TIGIT, IL1RAP, HER-2/HER-3, VEGF, and other immune and tumor-associated targets
Development of multispecific and multivalent peptide vaccine platforms
Peptide conjugation using click chemistry and advanced linker technologies
Structural design and optimization of conformational B-cell epitopes
Combination immunotherapy with chemotherapy, targeted therapies, and immune checkpoint modulation
Translation of peptide vaccines from preclinical models to Phase I clinical trials

Responsibilities

The successful candidate will:

Synthesize therapeutic peptide vaccine candidates using Fmoc solid-phase peptide synthesis (SPPS).
Develop and optimize peptide conjugation strategies, including CuAAC, SPAAC, thiol-maleimide coupling, PEGylation, and multivalent scaffold assembly.
Purify and characterize peptides using analytical and preparative HPLC, LC-MS, and MALDI-TOF mass spectrometry.
Execute studies evaluating vaccine immunogenicity and antitumor efficacy in preclinical models.
Collaborate with multidisciplinary teams in chemistry, immunology, oncology, and bioinformatics.
Analyze and interpret experimental data and maintain detailed laboratory records.
Prepare manuscripts for publication in high-impact journals.
Contribute to NIH grant applications, progress reports, and intellectual property development.
Mentor graduate students, technicians, and undergraduate trainees.
Present research findings at national and international scientific meetings.

IU School of Medicine is committed to being a welcoming campus community and we seek candidates whose research, teaching, and community engagement efforts contribute to robust learning and working environments for all students, staff, and faculty. We invite individuals who will join us in our mission to improve health equity and well-being for all throughout the state of Indiana.
