I enjoy sharing my knowledge and always appreciate teaching in which I have 18 years of experience.
Uppsala University, Sweden
From 1998 to 2005 I taught medical-, pharmacology- and nurse-students in the following subjects: hemodynamics (blood-vascular circulation-system), the safety of medical equipment (current), optical refraction of the eye, heart anatomy (dissection), oscilloscope and pacemaker and muscle structure and function. During this time I also supervised undergraduate and BSc biomedical students and lab assistants.
Plymouth University Peninsula Schools of Medicine and Dentistry, Plymouth, UK
From 2006 until present I have supervised PhD, BSc, and undergraduate students in different projects. Between 2006 and 2007 I taught medical students in 'Neurodegenerativedisorders' and 'Disease prevention and management-vaccines ‘and 2019 biomedical students in 'Tumours of the nervous system'.
- 2014 Internal and External Doctoral Examiners training
- 2011 Learning and Teaching for general Teaching Associates (GTA) training including: Theories of Learning and Teaching, Planning Sessions and Delivering Presentations, Learning in Groups, Evaluating Teaching and Giving Feedback, Assessment, Dealing with difficult Situations and Assessment Criteria and Marketing.
- 2008 Problem-based learning (PBL) facilitator training.
Research interests and experience
During my career I have been working on different projects including: 1) The development of immunomodulatory cancer vaccines to treat Acute Myeloid Leukaemia (AML) (Clinical Immunology),2)Investigation of the role of endogenous retroviruses in Multiple Sclerosis(MS)(Clinical Virology) and 3) Revealing the signalling of orexinergic receptors towards cell fate determination (Neuroscience).
Since January 2006 I have been working at Professor Oliver Hanemann’s laboratory (Plymouth University Peninsula Schools of Medicine and Dentistry, The Institute of Translational and Stratified Medicine). My work has centered on dissecting the signalling pathways involved in the development of Merlin-deficient tumours in order to find specific and effective therapeutic targets.
Ph.D. studentssupervision: 5 PhD students- first supervisor (DoS), 1- co-supervisor.
Our research team have received an award from Neurofibromatosis (NF) Advocature in recognition of our research and continued commitment to NF2. Additionally, my work within theNF2 field contributed to phase 0 clinical trials at our unit in collaboration with Manchester Hospital. My main goal is to find a good drug treatment for schwannomas and other Merlin-deficient tumours.
TAM family receptors as potential therapeutic targets in schwannoma and meningioma tumours
The role of cellular prion Protein (PrPC) in the development of schwannoma and meningioma tumours and its involvement in MDR.
The role of Endogenous retroviruse type K (HERVK) in the development of schwannoma and meningioma tumours.
p53/mouse double minute 2homolog complex deregulation in Merlin-deficient tumours
This project involved the investigation of the role of p53 deregulation in schwannoma development and targeting pathways involved in p53 degradation. In this project, I was first author.
Gas6/Axl-family receptors in schwannoma pathological proliferation, adhesion and survival
In this project, we have investigated the role of Axl receptor inschwannoma pathological proliferation, cell-matrix adhesion, and survival. In this project, I was the first and corresponding author.
The role of insulin-like growth factors (IGF1/2) signalling inMerlin-deficient human schwannomas
Insulin-like growth factor-binding protein-1 (IGFBP-1) regulates human schwannomaproliferation, adhesion and survival
In these studies, we have demonstrated that IGF1/2 and IGFBP-1 arereleased from schwannoma cells and IGF-I receptor overexpressed leading toincreased schwannoma proliferation and cell-matrix adhesion. In these projects I was first author.
Nilotinib alone or incombination with selumetinib is a drug candidate for neurofibromatosis type 2
In this project we have tested the therapeutic effectiveness of a PDGFRinhibitor Nilotinib and a MEK1/2 inhibitor selumetinib (AZD6244), in humanschwannoma in vitro model. In these projects I was firstauthor.
ErbB/HER receptoractivation and preclinical efficacy of lapatinib in vestibular schwannoma
This project was in collaboration with Dr Karajannis (USA) to test EGFR/HER inhibitor Lapatinib in human schwannoma in vitro model. In these projects I shared first authorship.
Targeting ERK1/2 activation and proliferation in human primary schwannoma cells with MEK1/2 inhibitorAZD6244
In this study, we have tested the therapeutic effectiveness of a MEK1/2inhibitor AZD6244, in human schwannoma in vitro model. In these projects I was first author.
Dissecting and targeting the growth factor-dependent and growth factor-independent extracellular signal-regulated kinase pathway in human schwannoma
Here we demonstrated that PDGFRβ is strongly overexpressed in schwannoma cells leading to increased schwannoma proliferation. We have also successfully tested a PDGFR/Raf inhibitor Sorafenib. In these projects, I was the first author.
Orexin Receptors in Recombinant CHO Cells. Signaling to Short- and Long Term Cells responses
The aim of this study was to investigate the mechanisms of orexin receptor coupling to the cascades regulating cell fate and also the assessment of the molecular determinants involved in orexin peptide-orexin receptor interaction.
Endogenous retroviruses in neurodegenerative diseases
This project focused on the investigation of the expression of the endogenous retrovirus (ERV9)-related proteins in peripheral blood cells and presence in sera from multiple sclerosis (MS) patients.
MSc research project
Immunomodulatory-and-cytokine gene-cancer therapy
The aim of this was to design cancer vaccines to treat leukemia and lymphoma. The vaccines would be implemented in both immunotherapy and gene therapy. For immunotherapy, human blood monocytes were separated and differentiated into dendritic cells for antigen presentation and activation of cellular immunity. For cytokine gene therapy, genes for various cytokines were transferred into acute myeloid leukemia (AML) cells via retrovirus- and adenovirus-based vectors.
I was involved in phase 0 clinical trials testing Sorafenib in Neurofibromatosis type 2 (NF2) patients. I perform tests on tumour tissue and blood samples from patients to look for the effect of these drugs on signalling pathways known to be involved in the development of Merlin-deficient tumours.
