Sven Nelander is a cross-disciplinary scientist focused on understanding, modeling, and treating brain cancers. With a background in medicine and mathematics, his research applies mathematical and experimental techniques to identify mechanisms and therapeutic targets, emphasizing cellular reprogramming to suppress tumor growth and improve therapies. Originally from southern Sweden, Sven studied medicine and mathematics in Lund before earning a Ph.D. in developmental processes in Gothenburg, doing early work in decoding cell type-specific gene regulation. As a postdoc in Chris Sander’s lab and later as an independent investigator, he invented new ways of modeling how cancer cells integrate perturbations from mutation, treatment, and stress. Since joining Uppsala University and SciLifeLab in 2012, Sven has built a research program linking tumor biobanking and neuro-oncology with modern systems biology, with support from several major foundations. He also serves as the founding director of CNSx3, a national center advancing modeling approaches for brain diseases. Outside the lab, Sven enjoys time with family, running, mushroom foraging, and restoring his summer house. He’s also an avid watercolorist with a passion for capturing light and fleeting moments in pigments.
Irem Uppman is a PhD student in Nelander lab. A molecular biologist by background, Irem is interested in investigating cell-states and clonal evolution in primary brain tumors. Her main projects focus on cell-state plasticity and invasion in adult and pediatric high-grade gliomas. She hopes to continue her career in research and contribute to our understanding of brain malignancies. In her free time, Irem likes to read (very quickly), knit (very slowly), take care of her plants (very poorly) and spend time with friends and family.
Anders Sundström is a bioinformatician working predominantly across the omics landscape along some ventures into system biology and image analysis. Since 2015, he has been part of the Neuro-Oncology program at the Department of Immunology, Genetics, and Pathology at Uppsala University. In his parallel personal journey, he spent a year at art school where he participated in a group exhibition at the Iziko National Gallery of South Africa, earned a green belt in capoeira and became a two-time champion in the international Gagarin Cup floorball tournament.
Madeleine started as a computational PhD student in Nelander lab in 2023, after earning her M.Sc. in Biophysics from Uppsala University the same year. Her work is focused on leveraging machine learning and image analysis to investigate the morphological and transcriptional heterogeneity and plasticity in glioblastoma. Her most recent work involves developing a method of single-cell tracking for in vitro and ex vivo settings, with the goal of following fluctuations in cellular morphology and protein expression over time. Outside of work, Madeleine dedicates most of her time to catching up with family and friends, as well as taking the occasional forest bath.
Hitesh Mangukiya specializes in studying the complex interactions between tumor cells, vascular cells, and microglia, with a focus on cell dynamics and invasion in glioblastoma. His current research centers on investigating cell dynamics, characterizing patient-specific tumor-endothelial interactions, and enhancing our understanding of glioblastoma’s invasive nature.
Josephine Heinold is a new Ph.D student in Sven Nelander’s group focusing on plastic changes of cell states in GBM and DMG based on CRISPR-Tag genome editing. Originally from Germany, she completed her bachelor in pharmaceutical Biotechnology in a small town called Biberach an der Riss. She continued her education at Uppsala University in molecular medicine focusing on cancer mechanisms at a molecular level. Josi likes to try to do it all in her free time by jumping from knitting, to half-marathons ending up playing the accordion to let her creativity flow while also keeping her house plants alive. She also loves to ‘keep the tan up’ by traveling to warmer places in the summer.
Rebecka is a PhD student in the group studying how primary brain tumors adapt and invade, focusing on single-cell technologies and CRISPR. She holds an MSc in Medical Biotechnology from the Royal Institute of Technology (2018). Along the way, she developed CRISPR-tag, a method for tracking protein expression at single-cell resolution in vitro and ex vivo, to reveal patient-specific treatment differences and identify new therapeutic targets. Resourceful, reflective, and resolute: Rebecka brings the same patience and playfulness to research as she does to life outside the lab, whether she’s knitting, spending time with her family, or hiking in remote landscapes.
Soumi Kundu, is a researcher with an experimental and molecular biology background. She focuses on understanding the biology of glioblastoma, particularly the mechanisms driving its progression into an invasive and aggressive tumor. She specializes in modeling glioblastoma using patient-relevant systems to address the critical challenges of studying tumor complexity. In her current project she employs in vivo genetic perturbation screening to unraveled networks and regulators driving tumor development, advancing our understanding of glioblastoma biology. Beyond the laboratory, she enjoys Indian classical music, spending time with walks in nature and water colorings at times.
Faidra Voukelatou is a PhD student in Nelander Lab studying glioblastoma invasion using zebrafish xenograft models. Her research investigates patterns of tumor growth and vascular migration, leveraging the zebrafish system to uncover mechanisms that drive glioblastoma invasion. By combining in vivo imaging with molecular analyses, her work aims to provide new insights into the cellular and molecular dynamics that underlie glioblastoma migration.
Filippa is a new Ph.D. student, having completed an M.Sc. in Engineering Physics with a focus on complex adaptive systems and high-dimensional data analysis. Their work centers on developing data-driven models to analyze Perturb-seq and spatial transcriptomics data, with the aim of uncovering spatially aware mechanisms driving glioblastoma invasion. Outside of work, Filippa enjoys crocheting, knitting, rollerskating, hiking, and reading - and considers trying new hobbies to be their favorite hobby of all.
Lioudmila is a research engineer in Nelander lab.
Mia is a research engineer in Nelander lab.
Clara Nordquist is a research assistant in the Nelander lab, working with sequencing and imaging data to understand the plasticity of glioblastoma cells and what affects it. She joined the lab in 2025, after finishing her MSc in molecular biotechnology engineering at Uppsala University. When not at work, you are most likely to find Clara out with her running shoes on, training for another long-distance race, or wandering the forests around Uppsala with her dog by her side.
