Priyanka did her BSc in Biotechnology and MSc in Microbial Gene Technology in India, followed by a PhD with Prof Pete Downes and Dr Nick Leslie at the University of Dundee studying Akt-independent mechanisms of tumour suppression by PTEN. For her post-doctoral research, Priyanka worked with Nick Leslie at Heriot Watt University, Edinburgh, studying  tumourigenesis in transgenic PTEN mice models . She then joined the Lab of Prof Markus Muschen at the University of Cambridge where she worked on the role of PTEN and PI3K in acute leukemias. She then briefly worked with Dr Elisa Laurenti at the University of Cambridge studying the role of inflammatory cytokines in haematopoietic stem cell function. Priyanka joined the Cell Signalling group in January 2017 to work on therapeutic intervention for PTEN Hamartoma Tumour Syndrome (PHTS).

Clinical PhD student

Victoria Rathbone
Victoria Rathbone, MBChB – PTEN hamartoma syndrome


Victoria is a Histopathology Specialist Trainee who gained her medical degree from Leicester University and an intercalated BSc in Haematology from Imperial College London. After graduating from medical school she obtained an Academic Foundation Programme post and spent her research time at UCL in Professor Flanagan’s lab, working on the development of a diagnostic test for H3F3A p.Gly34Try mutations in Giant Cell Tumours of Bone. Following foundation training she spent a further year in the same lab investigating circulating tumour DNA in chondrosarcoma and other bone tumours. She currently holds an Academic Clinical Fellowship and has been with the cell signalling group since June 2018, to focus on characterising mouse models of PTEN hamartoma syndrome. Victoria started her Clinical PhD studentship in April 2019 funded by Jean Shanks and the Pathological Society on the histological and molecular characteristics of PTEN-driven tumours.

PhD students

Georgia Constantinou
Georgia Constantinou, New mechanisms of PI3K-driven cancer development and alternative uses of PI3K-inhibitors in cancer


Georgia completed a BSc in Biomedical Sciences and later an MSc in Cancer at University College London. During that time she gained experience in a number of laboratories including the Vanhaesebroeck lab where she carried out her MSc research project which involved a screen of possible therapeutics for PTEN Harmatoma Tumour Syndrome (PHTS). After finishing her MSc, Georgia continued to, on a voluntary basis, work alongside Priyanka to work on a therapeutic intervention for PHTS. She officially joined the Cell Signalling group in January 2018, to investigate the effects of various drugs on the PI3K/Akt signalling pathway. Georgia started her CRUK-UCL Centre funded non-clinical PhD studentship in September 2019.

Sara Al-Jarrah Setó, Regulation of PI3Kdelta and alternative ways to modulate PI3Kdelta activity


Sara obtained the International Student Scholarship to complete her BSc in Pharmacy and Pharmaceutical Sciences (King Saud University, Riyadh) during which she worked on the formulation of nanocapsules for breast cancer dual therapy. Following that she did her MRes in Drug Design at UCL (2019-2020) and conducted two masters’ projects at the Centre for Inflammation and Tissue Repair on which she worked on the expression and purification of the recombinant protein PNPLA3 while also analysing problematic crystallographic datasets. Sara started her Marie Curie fellowship in October 2021 on understanding the role of activated PI3Kδ mutations in cancer with special interest in novel ways to modulate PI3Kdelta activity.

Fiona Black - Role of PTEN deregulation in early cancer development.


Fiona completed her BSc in Biological Sciences at Cardiff University in 2021. As part of her degree she undertook a Professional Training Year, for which she joined Dr Clare Davies’s lab at the University of Birmingham, which investigates the role of PRMT-catalysed post-translational arginine methylation in cancer. Fiona’s project focused on the RNA regulatory protein FXR1, a PRMT substrate, and its potential role in the regulation of DNA repair. Fiona joined the Cell Signalling group in October 2021 to complete her CRUK-funded PhD, focussing on growing organoids in which to answer questions about the early development of PTEN-mutant lesions.


Alberto Collado Remacha, Investigating signalling mechanisms of PI3Kalpha

Alberto completed his BSc in Biotechnology (UPV, València), 2019. During that time, he worked in Dr. Rosa Farras’ oncogenic signaling lab (CIPF, València). For his BSc thesis he conducted a pilot study with a novel pH dependent drug in tumoroshperes which was granted with honours. Then he enrolled in the MSc ‘Genes, Drugs & Stem Cells’ at Imperial College London and for his MSc thesis he joined Dr. George Poulogiannis’ lab (ICR, London) where the metabolic implications of PIK3CA in cancer gained special interest. The COVID-19 pandemic modified it into a systematic review of literature, obtained with distinction. In 2021 he joined the Cell Signalling group to continue research on PIK3CA signalling
