Cristina Xavier (CX) is an Invited Assistant Professor at IUCS-CESPU (since 2024),
a Lab Member of the Toxicologic Pathology Research Lab (UCIBIO–CESPU) and a Research
Collaborator at the Cancer Drug Resistance (CDR) Group at i3S. She currently serves
as Portugal’s Management Committee representative in the COST Action CA21116 (2023–2026),
dedicated to translational research in pancreatic cancer, reflecting her international
recognition in this field. CX holds an H-index 26 (Scopus) and has authored 46 peer-reviewed
publications (12 as 1st author, 11 as last or corresponding author), demonstrating
scientific independence and leadership. She graduated in Applied Biology from the
University of Minho (2006) and completed a European PhD in Health Sciences (FCT-funded,
2010) in collaboration with the Institute of Cancer Biology (Denmark), focusing on
the identification of novel compounds and combinatorial strategies to improve cancer
therapy. CX then secured a competitive 3-year postdoctoral contract (2012–2015) at
the Division of Cancer Therapeutics, Institute of Cancer Research (ICR-UK). There,
she led high-throughput functional screening approaches to identify key genes in pancreatic
cancer, and she developed drug-resistant pancreatic cancer models to evaluate novel
in-house compounds. She also contributed to multidisciplinary drug discovery programs,
being involved in the preclinical validation of 2 small molecules that progressed
into Phase I clinical trials, positioning her research at the interface of discovery
and clinical translation. In 2015, CX joined the CDR Group at i3S. After an initial
1-year postdoctoral fellowship (2016) investigating extracellular vesicles (EVs) in
drug resistance, she was awarded a competitive Individual FCT Postdoctoral Grant (2017–2023).
During this period, she established an innovative research line exploring macrophage-derived
EVs in pancreatic cancer resistance, in close collaboration with IPO-Porto within
the framework of the Porto Comprehensive Cancer Centre. This work secured funding
to lead a Beacon Project (2021–2022) and consolidated her scientific independency.
She also contributed to projects identifying novel drug combinations to overcome drug
resistance in lung cancer. Currently, CX leads a research line focused on discovering
novel molecular targets and rational combination therapies to counteract pancreatic
cancer drug resistance. Her most impactful contributions include: (i) the identification
of CHI3L1 as a driver of pancreatic cancer drug resistance (PMID:33212158); (ii) the
validation of CHI3L1 inhibitors capable of reversing resistance (PMID:33212158; 39225813);
and (iii) the generation of a drug-resistant pancreatic cancer cell line as an advanced
model for therapeutic discovery. Ongoing projects aim to validate innovative combination
strategies using advanced cellular systems. CX has supervised 5 PhD (4 ongoing), 13
MSc (2 ongoing), and 15 undergraduate (2 ongoing) students, demonstrating strong mentoring
capacity and commitment to advanced training. She actively participates in international
research networks through 4 COST Actions (CA24162, CA21135, CA21116, CA17104), fostering
collaborative projects and strengthening European integration. CX serves as Guest
Co-Editor of Special Issues in IJMS and Cells, is a Reviewer Board member of several
international journals, and has reviewed over 50 papers. She regularly contributes
to scientific committees, thesis juries, and national and international project evaluation
panels. She is an EACR Science Ambassador and a member of EORTC. She also teached
at the Faculty of Pharmacy, UP (2022-2023) and at Dep. Biology, University of Minho
(since 2022). CX received the Annual Scientific Productivity Award 2024 and 2025 from
CESPU-IUCS. CX has evolved into an emerging independent leader in translational pancreatic
cancer research, integrating scientific innovation, international collaboration, and
strong clinical and mentoring impact.
