Research interests

I am a microbiologist working in the field of nutrition, food science and biotechnology. My research focuses on how microbiomes both within the gut and along the food chain impact on human/animal nutrition, health and disease risk. I have a particular interest in host:microbe interactions and the inter-Kingdom molecular communication channels via bile acids and other microbiota related metabolites, which respond to diet and influence host health. My recent work has been focusing on the gut microbiota as a therapeutic target for nutritional interventions. I have been researching within the field of gut microbiology for a total of 14 years and I can now offer a 'scientific bridge' between Academia and industrial partners that look for expertise in the field of nutrition. This unique role has given me the opportunity to widen my horizons and appreciate the importance of certain types of analysis for the successful transition of a research discovery into a commercial product (the most popular from bench to bedside). I have developed a fascination for the microbial world of the intestine and how dietary changes can alter this world and hence impact on health. Results of my scientific research have shown great potential for translation into therapy.
Currently, with my independent research identity and leadership in research, I am in the position of capitalising on these experiences to move forward my scientific research into investigation of nutritional influences.




I am currently support with the development of any necessary emergency procedures for activities/areas involving the performance of clinical procedures.

I am collaborating with a team of academics and administrators in planning and delivering the undergraduate BSc Nutrition and Biomedical Sciences and Academic Degree programmes. I am overseeing quality assurance processes to ensure that programme standards are maintained, including regular evaluation of teaching and assessment methods and integration of employability skills. I am liaising with other departments and professional services (timetabling, registry, communications, recruitment) to coordinate programme delivery. I am working on incorporate innovative approaches to placements, in addition to the newly established placement year, and I am investigating courses for the wider workforce such as health coaching practical nutrition diploma and short courses; in fact, the MSc Clinical Nutrition modules lend themselves to be taken as individual courses. As a part of Nutrition and Health Team already I lead CPD for the professional organisations such as the Association for Nutrition, British Dietetics Association and MyNutriWeb, since CPD is essential for all Registered Nutritionists and Dietitians. Moreover, I have been working with the British Nutrition Foundation (BNF) to not only offer student internships but to create links with their funders who are food producers and manufacturers, retailers, and food service companies, for research, Knowledge Exchange and to further the dissemination of research findings.

As well, I managed different modules for PG and MRes students providing me with the opportunity of deepening my knowledge and understanding of clinical sciences and nutrition in a social or behavioural context, as well as behavioural and multilevel strategies to implement overall health within the population. I engaged in planning both teaching and assessment across the curricula and I used module evaluations and feedback to improve the student experience, but not at the expense of dropping standards. I ensured that module development is effective and appropriate to the needs of the students and the required learning outcomes.

Till now I am convener of two MSc modules in Clinical Nutrition (Dissertation HEP060L004Y and HEP060LD04Y and Body Composition Practical HEP020L035Y for 60 MSc in Clinical Nutrition students). I also the Module Convener for Food Science - HEA020N223Y for a total of 40, 2nd year BSc Nutrition and Health.

Contribution to other Modules: Nutrition in Acute and Chronic Illness HEP020L037A & HEP020LD37A, Advances in Nutrition and Health - HEA020X339Y, Nutrition through the Lifespan - HEA020N212Y, Public Health and Health Promotion - HEA020N213Y, Public Health Approach to Cardio-Metabolic Diseases - HEP020L076S, Integrated Approach to Obesity - HEP020L114Y, Communication HEP020L002Y, Research Methods - HEP020L001A.

I as well supervising and lead MRes Research Projects in the field of microbiome and clinical nutrition. Over the past 20 years, I have developed my experience through supervising undergraduate, MSc and PhD students (including experienced researchers) in the laboratory. I have provided support during study conception, data analysis, offered feedback and assessed students’ understanding and knowledge through formative presentations.

I have successfully planned and designed teaching and learning activities (e.g. lectures, seminars and laboratory/field practical sessions across all years (2nd year undergraduates, MSc and MRes students) ranging from modifying/updating previously delivered material through to the design and delivery of completely new contents and sessions as appropriate.

Thus, I revised module descriptions as a part of our programme revalidation process and I also contributed to the curriculum review in Health Sciences.

I regularly present my work at group meetings, seminars, project meetings, dissemination events and conferences informing my research knowledge and provide pedagogical thinking on how to link research and teaching. I always endeavour to create for my students an inclusive learning environment where they can benefit from a variety of support and guidance. I give individual supervision and mentoring sessions as well as run meetings in groups of peers using similar methods to conduct their research. I encourage them to work together sharing their laboratory’s work on projects that are of a similar nature. I think this enriches the teaching and learning environment where students can find common ideas and perhaps extend their academic interactions to a social setting, which is especially important for international students who are away from their home. In my experience with a varied student population in the Nutrition, Biomed and Health programmes, group and team approaches in student supervision can be extremely beneficial, particularly with international students to help them to fully integrate in the new academic and social environment.

I am conducted impactful independent research projects utilising key modelling and analysis techniques, effectively communicating research findings through publications, presentations, and participation in conferences. I am successfully supervised PhD students and mentored younger colleagues, fostering their professional growth and development in a computational research environment. I was also a Visiting Lecturer at the University of Hertfordshire, London for the Nutrition and Health (NH2; year 2 food science students) from 2015 to date, and a Visiting Lecturer at the University of Surrey-MSc in Nutritional Medicine.

Notable Achievements

Significant learning and development activities undertaken in previous 5 years

Setting up (2015-2016) and leading a brand-new gut microbiome laboratory at the Department of Life Sciences, University of Roehampton. Gut microbiota research is a rapidly developing area within life sciences and my expertise and experience were instrumental in establishing this new laboratory and opening it for internal and external collaborations. To date, I conduct the innovative research linking diet to microbes throughout the human lifespan and its impact on health and disease that remain fruitful areas of new research investment by industry as evidenced by the priorities of biotech companies with whom I collaborate and who are already funding my ongoing research. I brought with me the unique equipment for in vitro glass colon fermentation systems purchased with my grants from Reading University. Several successful external grants have been attracted to Roehampton thanks to this new laboratory and a group of researchers formed that I supervise; it includes PGRs, visiting researchers and post-doctoral fellows.

Since that I joined the University of Roehampton, I gained experience in teaching in higher education and within a healthcare setting.

I have contributed to improve the Clinical trial’s setting at the Life Sciences. Since 2020, my expertise and experience were instrumental in creating suitable suites and a designated area in our laboratory for all work involving venepuncture procedures (phlebotomy/cannulation/infusion). I am stepping up with my expertise continued to provide support with the development of risk assessments and Standard Operating Procedures (SOPs) for clinical human intervention procedures that are performed by University ‘employees, to ensure the risk assessments and the SOPs are reflect the standards expected in professional clinical settings.

I also been advice and arrange the Good Research Practice as a part of the Research and Knowledge Exchange workshop series in collaboration with medical consultants at Imperial College Hospital in London.

Up till now, I have demonstrated expertise in grant writing, securing funding for research projects, and actively collaborating with multidisciplinary teams on scientific advancements.

Since last April 2023, I have been involved in the BIG Health Innovation Network (HIN) - Recruitment Events with the aim to Improve health and well-being in South Londoners. The BIG Health Innovation Network is a free networking programme for SMEs in South London. In joining this network, SMEs will have the opportunity to grow and development their business and/ or entrepreneurial potential while at the same time improving the health of South Londoners and benefiting from a networking platform made up of similar business partners and relevant academics.
