Principal Investigator
Santiago Correa
Prof. Correa heads the Nanoscale Immunoengineering Lab. His research interests lie in developing biomaterials and nanotechnology for reprogramming the immune system.
Postdoc
Robert Hincapie
Programmable self-assembling materials; protein chemistry and bioconjugation; glycans in immunology
Born in New York, Robert has been slowly making his way back up north. He did his Ph.D with M.G. Finn at Georgia Tech, where he worked on developing protein nanoparticle glycoconjugates for immunotherapy. He joined the Correa lab to further explore the role of glycans and self-assembling materials to precisely direct immune responses.
Ph.D. Candidate
Ryan R. Hosn
Engineering injectable hydrogels for the induction of immune niches
Raised in Gambia to a Lebanese family, Ryan completed his education in Spain. Fascinated by the intricacies of the human body and driven by a desire to build tools, he pursued a bachelor's and master's in bioengineering. After two and a half years as a research technician in Dr. Darrel Irvine's lab at MIT, Ryan is now applying the skills he has acquired over the years to modulate the immune system in immune-related diseases.
Ph.D. Candidate
Artemis Margaronis
Designing bioactive extracellular vesicle hydrogels for immunomodulation and tissue regeneration
Originally from Athens, Greece, Artemis spent the second half of her life in Bethsda, MD. In the Correa Lab, Artemis is exploring how extracellular vesicles can be used to formulate bioactive hydrogels that modulate immune responses and promote tissue regeneration. Outside of research she enjoys FaceTiming her dog, Millie, yoga classes, long walks, and beach trips.
Ph.D. Candidate
Sarah Bortel
Harnessing biomaterials to reprogram "cold" tumor microenvironments
Sarah engineers bioactive materials that localize and potentiate immune signals to overcome the barriers of treatment-resistant tumors such as pancreatic ductal adenocarcinoma (PDAC). Her work aims to improve the potency, durability, and efficacy of next-generation immunotherapies. Outside the lab, Sarah teaches bioengineering through Columbia's Science Honors Program and ceramics at Uptown Clay.
Ph.D. Candidate
James Wang
Developing biomaterials for modulating T cell fate and activation
With varied experiences in the drug discovery, autoinflammatory, and cognitive science spaces, James is excited about improving understanding and efficacy of cancer immunotherapies. In his free time James enjoys cooking, exploring new places and cuisines, and talking about Costco.
Co-advised Ph.D. Candidate
Satya Nayagam
Engineering targeted gene delivery vehicles
With a background in nanoparticle formulation and characterization, Satya is passionate about developing biomaterials that enable targeted gene delivery. Satya completed his undergraduate training in the Prud'homme Lab at Princeton University and is currently co-advised by Prof. Kam Leong. Outside of lab, he enjoys traveling and flying small planes above the cornfields of his native Ohio.
Co-advised Ph.D. Student
Oriana Marrone
Single-cell genomics-guided design of immunomodulatory biomaterials
Born and raised in Venezuela, Oriana moved to Miami, FL to pursue her B.S. and M.S. in Biomedical Engineering. During her M.S. research work, Oriana got really interested in biomaterials for immunomodulation in hydrogels. She now hopes to integrate her expertise in biomaterials with single-cell genomic tools to help her better design systems that elicit specific immune responses. Outside of lab, she is a full-time cat mom.

M.S. Student
Ethan Kriss
Ethan completed his bachelor’s degree in biomedical engineering at Tufts University, where he worked in Dr. David Kaplan’s lab on neural tissue engineering and therapies for Glioblastoma Multiforme. Fascinated by programmable biomaterials, he joined the Correa Lab to explore how hydrogels can modulate immune interactions to fight cancer. Outside of lab, Ethan enjoys cooking and running through Central Park.
Undergraduate Researcher
Daniella Uvaldo
Developing cell-derived nanovesicles for drug delivery applications
As a biomedical engineering student, Daniella is passionate about the intersection of medicine and technology to create a healthier future. Specifically, her research involves deriving nanovesicles from mammalian cells for therapeutic applications. Outside of the lab, Daniella is involved in the undergraduate Biomedical Engineering Society and CU Public Health Club.

Undergraduate Researcher
Mackenzie Wright
Liposome encapsulated drugs for targeted cancer immunotherapy
Passionate about the intersection of biotechnology, medicine, and computational innovation, Mackenzie aspires to be a physician assistant. Her research engineers liposome-based drug delivery systems to improve targeted treatments for diseases like pancreatic cancer. She also plays on the Columbia’s club volleyball team, is active in the Women in Computer Science (WiCS) club, and enjoys playing piano.
