Dr Constandina Pospori (Post Doctoral Researcher)

I studied medicine and obtained my PhD in Tumour Immunology in 2013, as a UCL MBPhD student. In my PhD, with Prof. Emma Morris and Prof. Hans Stauss, I investigated the phenotype and function of T cells specific for the tumour-associated antigen WT1 and showed for the first time that T cell specificity for a tumour-associated, self-antigen mediated the spontaneous generation of functionally competent, memory phenotype T cells rather than tolerance. I moved from UCL to Imperial College and entered the world of stem cells , where I studied the recruitment of endogenous progenitor cells with pro-angiogenic potential towards the site of bioengineered transplants with Prof. Sara Rankin. 

In 2016, I joined the Lo Celso group to investigate the dynamic interactions between T cells, Leukaemia and Haematopoietic Stem cells throughout the course of disease as well as in the presence of T cell Immunotherapy. My project is funded by Bloodwise. Being a big fan of science, I love sharing my enthusiasm for it and communicating my work with the public and I have taken part in the Imperial Fringe, the Imperial Festival and the Science Museum Lates. With the not-so-secret hope that my little ones will choose to study science when they grow up, I have also enjoyed school visits to talk to a class of 5year olds about DNA and I have been amazed by their inquisitive minds!

 Richard J Burt (Clinical Post Doctoral Fellow)

I studied medicine at the University of Otago in New Zealand before moving out to the U.K. to complete my Core Medical and Haematology specialist training. I was then fortunate to obtain a CRUK-funded PhD studying the role of stromal cells in treatment resistance in acute lymphoblastic leukaemia (ALL) in Adele Fielding’s lab at UCL in 2015. During my PhD we made the exciting discovery that stromal cells rescue leukaemia cells from chemotherapy induced oxidative stress by transfer of mitochondria. This led to my obsession of all things metabolism and microenvironment-related! Following my PhD I took up a 1 year post-PhD fellowship in Mariia Yuneva’s group at the Francis Crick Institute to understand more about the metabolic perturbations in the treatment resistant leukaemia population. In 2021 I was awarded a CRUK Clinician Scientist Fellowship at Imperial College in the Lo Celso lab. My current work is on identifying metabolic vulnerabilities in the treatment resistant population in B-ALL with a focus on cystine metabolism. I also work at UCLH as an honorary Haematology Consultant treating adults and young adults with leukaemia and myelodysplastic syndromes.  

 Sara González Antón (PhD student)

I studied Biology at University of Leon and a Masters in Regenerative Biomedicine in University of Granada, both in Spain. I have always been very interested in stem cells and tissue regeneration. When I moved to London, I joined Cristina’s lab for an internship and stayed to work as a research assistant. This experience allowed me to get involved in multiple projects, get to know different people and fall in love with microscopy!

In 2018, I got the opportunity to start a PhD under Cristina’s supervision fund by CRUK. In my project I focus in understanding how acute myeloid leukaemia and chemotherapy disrupt the niche, how this remodelling affects haematopoietic stem cell transplantation and I am trying to find new targets to improve this process. Outside the lab I love wandering around London, traveling and enjoying any kind of art!

Christiana Georgiou (PhD student)

After obtaining my degree in Biological Sciences at University of East and Anglia and Masters in Genetics of human Disease from University College London I fall in love with science and research. For couple of years as Research Assistant, I explored science from different angles, from neural development and differentiation, parasympathetic system activity after ischaemic episode to studying retrotransponsable elements in Acute Myeloid Leukaemia patient samples. Working with blood and particularly haematopoietic stem cells (HSCs) fascinated me and wanted to understand deeper how disease affects them. So in 2019 I joined Cristina’s group as a PhD student. My project, funded by Welcome Trust, explores a) haematopoietic stem cell heterogeneity in severe infection and b) understanding heterogenous HSCs interactions with Bone marrow microenvironment in the context of infection. 

Outside the lab I very much enjoy going to the gym, exploring the world, playing the piano and read psychology books.

Andrew Killeen (PhD student)

I obtained an MEng in Mechanical Engineering from the University of Southampton in 2017. During my undergraduate studies I gradually became more interested in applying the concepts I was studying to biological problems, with my research projects focussed on modelling blood flow through a stent and lubrication within a novel hip implant. These experiences applying fluid dynamics to biological problems led me to apply to Imperial College’s Centre for Doctoral Training (CDT) in Fluid Dynamics. As part of the CDT I obtained an MRes in 2019 - with my thesis focussing on the design of a scaffold for retinal implants - before starting my PhD in the Bioengineering department under the supervision of Dr. Chiu Fan Lee and Dr. Thibault Bertrand.

My research focusses on modelling cellular dynamics and interactions to understand the causes of emergent behaviour seen experimentally. I am collaborating with the Lo Celso lab to model interactions between healthy and leukemic cells in the bone marrow, to better understand how leukaemia outcompetes healthy haematopoiesis.

Marine Secchi (Master+PhD student)

I moved to London to study Biology at Imperial, with a year in industry. I worked at GSK for a year and loved doing research and applying the knowledge I had of Immunology. I got into the Molecular and Cellular Basis of Infection Wellcome PhD program to pursue my interest in the interactions between pathogens and our immune system. I did a 3-month project in Cristina' and Tiago's labs and really discovered the stem cells field, I found it fascinating. I will now be investigating platelet-biased stem cells and platelet replenishment following depletion and infection. Outside of the lab I'm part of the synchronized swimming team and I love exploring London and going to the theater/ cinema.

If you are interested in joining the group as a PhD student or posdtoctoral researcher please get in touch (c.lo-celso@imperial.ac.uk).

We do not have open positions at the moment, but you may be eligible for support to apply for your own funding.

Ben Partridge (PhD student)

CHIARA PIRILLO (PhD Student)

I received my BSc and MSc from the University of Pisa, Italy, in Molecular Biology and Biology applied to Biomedical Sciences, respectively. For my MSc thesis, I have spent one year at King’s College of London where I focused on Neural Stem Cells and Brain Tumours using Drosophila Melanogaster as model organism. This experience allowed me to discover my deep passion for stem cells and is one of the main reasons that has led me to the choice of working in this field.

In October 2016, I joined the Lo Celso group to start my PhD project, which is funded by Bloodwise. I am interested in understanding the interaction between invading leukaemia, declining healthy haematopoietic cells and remodelled stroma cells in the bone marrow using a range of techniques including intravital imaging. In my free time I like to travel and discover new places and relevant cultures.

Myriam Haltalli (PhD student)

After having graduated with a degree in Genetics from Queen Mary University, I joined Imperial for a masters in Biomedical Research, where I developed an interest in Infection and Immunology through my research projects. This led me to apply for and gain a place on the Wellcome Trust Molecular and Cellular Basis of Infection programme where I had the opportunity to spend some time with different research groups working on topics ranging from the neonatal immune response to Influenza and investigating the epigenetic regulation of HTLV-1.

I eventually joined the Bone Marrow Dynamics group, in October 2015, to start my PhD project  supervised by Cristina Lo Celso and Andrew Blagborough. I am interested in understanding the role of the bone marrow microenvironment in the response of haematopoietic stem cells to malaria infection using a variety of techniques including intravital imaging. When I am not stuck in the lab, I enjoy travelling.

Delfim Duarte, MD (PhD sTUDENT)

I graduated in Medicine from the University of Porto, Portugal in 2012. As an undergrad, I participated in projects looking at angiogenesis and inflammation and completed a Master’s on cell microparticles, under Raquel Soares supervision. In 2011, I was selected by the Harvard Medical School–Portugal programme for a small internship at Tom Kirchhausen’s lab, where I studied dynamin in clathrin-mediated endocytosis. In 2014, I entered in the specialty training of Haematology, which I interrupted to pursue a PhD through GABBA (gabba.up.pt).

In October 2014, I moved to Imperial College London to start a PhD project under Cristina Lo Celso’s supervision. I’m interested in intravital imaging and understanding the role of the bone marrow microenvironment in leukaemia development. I love to travel and am a great fan of art, history and gastronomy.

Nicola Ruivo (research technician & lAB MANAGER)

I studied at Stellenbosch University in South Africa where I received my B.Sc in Human Life Sciences.  I then went on to do an M.Sc in Molecular Biology & Genetics where I developed molecular tools to find quantitative trait loci in commercially reared abalone.  I relocated to the UK in 2008 and joined Imperial College London in 2009 in the Centre for Molecular Biology and Infection (CMBI) where I was fortunate enough to work in two infection groups over 2.5 years as a Research Technician.  This enabled me to develop my technical laboratory skills and gain a greater understanding in host-pathogen interactions.  I joined Dr Lo Celso’s lab in 2011 and have since furthered myself as a researcher by gaining insight into haematopoietic cell biology.  I also have the role of lab manager which helps keep the lab running smoothly and the whole team working efficiently.  It should also be noted I’m a great cook and an excellent baker.

Dr Edwin Hawkins (Postdoctoral fellow, now group leader at WEHI, Melbourne)

I originally studied for my BSc at Otago University in New Zealand before moving to the Australian National University in Canberra, Australia for my honours degree. I relocated to the Walter and Eliza Hall Institue to conduct my PhD studies developing quantitative models and using miroscopy to study single cell lymphocyte behaviour. After my PhD, I obtained an NHMRC Early career fellowship to study molecular mechanisms that regulate cell fate decisions in protective and malignant lymphocyte populations. I moved to Dr Lo Celso's laboratory to study how the fate of single cells is regulated by interactions with the microenvironment. My work is currently funded by a European Haematology Association (EHA) Young Investigator Fellowship a project grant from Leukemia and Lymphoma Research (UK).

Dr Narges Rashidi (Postdoc, now at Ragon Institute, Boston MA)

DR REEMA KHORSHED (POST DOCTORAL RESEARCHER)

I graduated in software engineering (B.Eng) with a first class degree in 2007 at the University of Bradford, UK. I then completed my masters in informatics by research and PhD in biological image analysis at the same university. During my PhD I investigated and developed a cell level automated approach for quantifying antibody staining in immunohistochemistry images. This allowed me to employ my computational skills into producing biological solutions by bridging computing, microscopy and biology together. In 2013 I joined Dr LoCelso group at Imperial College London, where I had the opportunity to employ my image analysis expertise to designing and developing advance image analysis tools for the automated quantification of large 3D in vivo imaging data. I then became increasingly fascinated by the interaction of haematopoietic stem cells (HSCs) in the bone marrow microenvironment and their relation to their complex niches. Therefore, I had undergone extensive training at the LoCelso lab on cutting edge intravital microscopy approaches and murine experimental models to study the interaction of haematopoietic and their relation to their complex niches in three dimensions and in real time. This has widened my expertise and gave me the opportunity to integrate all these skills collectively to investigating novel biological findings in the stem cell biology field as well as developing state of the art customized image analysis and quantitative tools.

Emanuel - Visiting student

Ecem Kirkiz (MRes Student)

I recently graduated from King’s College London with a BSc (Hons) degree in Molecular Genetics with Extra Mural Year which I completed at the University of Oxford. I am currently an MRes Molecular and Cellular Biosciences student, undertaking the first lab project of my degree within the Lo Celso group. Here, I study the role of bone marrow derived macrophages in acute myeloid leukaemia development through examining a specific chemokine-chemokine receptor interaction between these cells. My ultimate aim is to understand whether AML cell homing and migration is negatively affected when this chemokine receptor is knocked out on the AML cells, possibly revealing one important way through which AML development and progression in the bone marrow is enabled by bone marrow macrophages. 

Alba Rodriguez Meira (Mres Student)

I studied Biotechnology at the University of Salamanca, Spain, and moved to London to join the Master Research in Cancer Biology at Imperial College London. Since the very beginning of my research career I have always shown a particular interest about this disease, firstly working in the Cancer Research Centre (Salamanca, Spain) and then at the Department of Surgery and Cancer at Imperial College. I joined Cristina Lo Celso’s Group for the first rotation of my MRes course, focusing on the cellular and molecular crosstalk between leukemic cells and the bone marrow niche.  This rotation has been a great opportunity for learning powerful imaging techniques that will be for sure extremely valuable for my future research. Next year I will continue my career doing a PhD and further developing my passion about cancer biology at the University of Oxford.

Zahra Aboukhalil

I did my undergraduate degree in Biochemistry at Imperial and am now doing my MRes in Molecular and Cellular Biosciences. I have done two of my rotations in this lab. In my first project I used photoconvertible fluorescent proteins in vitro and learnt a lot about confocal microscopy. In my current project I’m lookin g at the effect of TNFα on cultured haematopoietic stem and progenitor cells and am learning a lot about flow cytometry. For this project I have the great help of Rachel the undergrad in the lab! Next year I will be starting my PhD at the Weatherall Institute of Molecular Medicine, University of Oxford. For my PhD I plan on characterising self-renewal in haematopoietic stem cells. My projects in Cristina’s lab have interested me in haematopoietic stem cells and hopefully I’ll continue with this in the future!  

THOMAS WILLIAMS (MRES STUDENT)

I recently completed a BSc in Pharmacology, during which I developed a keen interest in immunology and cancer –related inflammation. I am delighted to have joined the Lo Celso lab as a Master’s student and am currently investigating the complex interaction between T lymphocytes and leukemic cells in vivo, with the aim of understanding how cancers escape immune surveillance. I hope to continue working on pressing scientific questions, with the aim to develop and improve therapies for patients.

William Foster

I’m working in Cristina’s lab for the final rotation in my MRes course. My project attempts to deconstruct the haemopoeitic stem cell niche in leukaemic conditions. To do this I am looking at the interaction of macrophages derived from the bone marrow with a mouse model of acute myeloid leukaemia. Outside of the lab I am still an active member of a few student societies, most notably the rock and heavy metal society, where I was president in my last two undergraduate years and co-hosted their radio show on ICRadio this year.

An Imperial College Biochemist of Class 2014. I am cur rently doing a UROP placement in Cristina's lab involving the sorting of lineage negative cells using FACs alongside Zahra. I am so thankful for this opportunity. Everyone in the lab has been so friendly and helpful! I have learnt so much during this short placement. I will be continuing my education with an MRes (Stem Cells and Developmental Biology) at UCL in September. I am highly interested in the field of Regenerative Medicine and am keen to learn more about how we can use stem cells to culture the growth organs in a dish. Editors Note: Rachel is officially Zahra's lucky charm for all experiments!

Sandra Sullivan 

I am doing an MRes in Molecular and Cellular Bioscience and my interest in cancer biology has brought me to the Lo Celso group for my 2^nd lab rotation. I am researching acute myeloid leukaemia and novel ways to disrupt the leukaemia-bone marrow interactions to tackle chemoresistance to chemotherapy drugs. My interest in cancer biology started during my BSc in Biomedical Science and evolved into many projects I have been involved in, including cancer clinical trials in melanoma, breast cancer research and now leukaemia. I hope to take my passion for the field into a PhD, soon after I finish my MRes. When I’m not studying I love cooking! My specialty is Portuguese Fish Stew and Moroccan lamb tagine! I absolutely love the Mediterranean, the warmth, the sun, the beaches but especially the food.’
