Prof Louis Vermeulen is a group leader/principal investigator within the Center for Experimental Molecular Medicine (CEMM), Laboratory for Experimental Oncology and Radiobiology (LEXOR) at the Academic Medical Center (AMC), Amsterdam. Louis Vermeulen studied medicine and obtained his PhD at the AMC, and afterwards worked as a research fellow at the University of Cambridge, UK. His group uses quantitative approaches in combination with state of the art in vitro and in vivo models to study the biology of intestinal cancers in order to improve tumor classification and therapies. Louis Vermeulen is supported by several personal grants, including an ERC starting grant, a VIDI grant from the Dutch Science Organization (NWO/ZonMw), and a career development grant of the Dutch Digestive Foundation (MLDS). He is a EMBO Young investigator and in 2017, he was awarded a Young Investigator New York Stem Cell Foundation (NYSCF) grant.


Laura Schwarzmuller, MSc

Laura, originally from Germany, did her Bachelor’s and Master’s in Molecular Biotechnology in Heidelberg. She performed her Master thesis in Hanno Glimm’s lab (NCT, Heidelberg) where she worked on IGF2-dependency in colorectal cancer. In November 2017, she joined the Vermeulen lab as PhD student. Her project is focused on the role of long non-coding RNAs in colorectal cancer. Together with Nicolas Leveille she is interested in identifying Wnt-regulated lncRNAs that are involved in transcriptional regulation and other processes in colorectal cancer (stem) cells. By screening a panel of colorectal cancer cell lines they aim to identify transcripts that play a crucial role in the signalling pathway and are biologically relevant for cancer cells.


Oscar Bril

Oscar did his Bachelor’s in Molecular Life Sciences and Master’s in Drug Innovation at Utrecht University. His two internships were with dr. Frank Redegeld (Pharmacology, Utrecht University) on the development of a high-throughput confocal microscopy method for detecting the effects of nutrition and mast cells on colorectal cancer, and prof. dr. Gunnar Nilsson (Immunology & Allergy, Karolinska Institutet, Stockholm) on alternative cytokines and growth factors for the culturing of mast cell progenitors. He joined the Vermeulen lab in may 2020 as a PhD student. Together with Nicolas Leveille, he will perform genome-wide functional screens to unravel oncogenic lncRNAs in colorectal cancer.

Ronja Adam, MD, MSc

From 2016 to 2021 she has followed a PhD trajectory in the Vermeulen lab to study the role of microRNAs and long non-coding RNAs in colorectal cancer and to broaden her skills in computational biology and genomic analyses.


Nicolas Leveille, PhD

Nicolas completed his postdoctoral studies in 2015 at the Netherlands Cancer Institute (NKI). During these years he developed an interest to understand how complex noncoding RNA regulatory networks shape gene expression and biological processes. He then joined the Vermeulen lab to apply his expertise on noncoding RNAs to colorectal cancer. In addition, Nicolas recently obtained a KWF grant to develop lineage tracing tools, which will help to uncover how cell population dynamics drive tumor growth, response to therapy and tumor progression.


Sanne van Neerven, MSc

Sanne van Neerven performed her Bachelors in Biomedical Sciences at the University of Amsterdam, and her Master Oncology at the VU Medical Center. After her Masters, she was awarded an NWO-OOA full PhD scholarship and landed in the lab of Louis Vermeulen. Her interests comprise all stages of colorectal cancer development, but her work mostly focuses on the initiating steps leading to the development of pre-malignant adenomatous polyps. More specifically, she studies the competition of healthy and mutant stem cells within the colonic crypt by implementing both in vitro organoid cultures and in vivo mouse models. Insights in this competition aid the development of chemopreventive strategies that could specifically benefit patients with heritable colorectal cancer predisposition syndromes such as familial adenomatous polyposis and Lynch Syndrome.


Leandro Ferreira Moreno, PhD

After completing his graduation in Biology, Leandro received his Master degree in Molecular Biology/ Biochemistry at the Federal University of Paraná - Brazil. During this time, he was working on the development of a pipeline for in-silico prediction of non-coding RNAs in bacteria using RNA-seq data. In 2013, Leandro moved to the Netherlands to do his PhD at the Westerdijk Fungal Biodiversity Institute - Utrecht. In November of 2018, Leandro defended his PhD thesis entitled "The Biology of Black Yeast genomes". In October of 2018, Leandro joined the Vermeulen group as a bioinformatician, where he is studying the presence of long non-coding RNAs in different cell lines of colorectal cancer by applying GRO-seq technology.

Sanne ten Hoorn, MD, MSc

Sanne ten Hoorn is a medical doctor. For her PhD she works on using the consensus molecular subtypes to predict the anti-EGFR response in metastatic colorectal cancer and on the implementation of the consensus molecular subtypes in the clinic.


Maartje van der Heijden, MD, MSc

Maartje van der Heijden studied Medicine at the Academic Medical Center (AMC) in Amsterdam. From early-on she was interested in oncology and during her studies she worked as a research assistant at the Laboratory for Oncology and Radiobiology (LEXOR) in the AMC and in the Tabar group at the Memorial Sloan-Kettering Cancer Center based in New York. After obtaining her Medical degree, she continued her scientific career as a PhD candidate under the supervision of Louis Vermeulen. Here, in close collaboration with other group members, she studies factors that influence the malignant transformation and outgrowth of intestinal (stem) cells, both in a qualitative and quantitative fashion. In addition, she studies the clonal growth dynamics of colorectal cancer in homeostasis and under drug pressure. Furthermore, she aims to unravel different therapy resistance mechanisms to commonly used chemo- and targeted therapies for CRC.


Sophie Lodestijn, MD, MSc

Sophie Lodestijn was born in Nijmegen. In 2007, she moved to Amsterdam to study Psychobiology at the University of Amsterdam and later Medicine at the Amsterdam Medical Center (AMC). She finished Medical school in 2015 and started her PhD project at the Center for Experimental and Molecular Medicine at the Amsterdam UMC under supervision of Louis Vermeulen and Maarten Bijlsma. The main focus of her project is to understand the stem cell dynamics in established colorectal cancer and pancreatic ductal adenocarcinoma. She uses a marker-free lineage tracing system in combination with a mathematical model for tumor growth to define the clonal dynamics during unperturbed tumor growth. This way different cancer types can be compared. In another project Sophie tries to unravel the stem cell dynamics during development and homeostasis in the heathy tissues.


Sanne Bootsma, MD, MSc

Sanne graduated medical school in 2017, after which she worked for one year as a resident-not-in-training at the internal medicine department of the Slotervaart hospital in Amsterdam. In 2018 she joined the Vermeulen lab to start a PhD. The focus of her project is on finding common vulnerabilities of molecular subtypes across gastrointestinal cancers. Furthermore she will work on orthotopic mouse models for gastrointestinal cancers, to test novel subtype specific therapeutics.

Kristiaan Lenos, PhD

Kristiaan studied Life Science and Technology in TU Delft and University of Leiden, followed by a PhD in Molecular Cell Biology at the Leiden University Medical Center, where he studied the regulation of the key tumor suppressor p53. After a 2 year postdoc at the VUMC, he joined the Vermeulen lab in 2014, to work on colorectal cancer stem cell dynamics. This work revealed an important role of the tumor microenvironment on cancer cell clonogenicity, therefore the cross-talk between cancer cells and surrounding cells is now one of his main research topics. Blocking these signals might be a promising new therapeutic approach to treat cancer patients. Another part of his research focusses on the formation of peritoneal metastasis in colorectal cancer patients. Studying the molecular pathways involved in this process could provide new strategies to prevent or treat this condition.
