Team & responsibilities
One study, two complementary forms of leadership
Alejandra Benavides Rojas leads the experimental and primary analytical pipeline. Dr. Sandra Perdomo advises the scientific strategy, protocol, interpretation, and computational extensions. Their work converges on the same specimens and sequencing files, allowing methylation, immune, and—subject to feasibility—fragmentomic signals to be interpreted together.
The study is connected to InMubo, the Cellular and Molecular Immunology Research Group at Universidad El Bosque. The university describes a program spanning cancer immunology, mucosal immunity and infection, autoimmunity, systemic inflammation, and research training.

Advisor · Universidad El Bosque
Sandra provides scientific and translational direction:
- ground the hypothesis in colitis and cancer biology;
- verify protocol, regulatory, and analytical coherence;
- guide fragmentomics feasibility and interpretation;
- direct comparison with public cancer resources;
- connect DMRs to pathways and biological systems; and
- keep exploratory findings aligned with validation requirements.
Clinical network
Recruitment and screening are described as taking place with gastroenterologists Viviana Parra, Cristian Flores, and Ricardo Villareal across Los Cobos Medical Center, GastroAdvanced, and HIC Bucaramanga.
The project presentation identifies approval by the HIC Bucaramanga–Fundación Cardiovascular de Bucaramanga research committee under Minutes 005-2024, with the study framed under Colombian Resolution 8430 of 1993.
