Biography

Biography

I am an Associate Professor in Molecular Microbiology and Employability Coordinator in the School of Biomedical Sciences. I teach and research in the field of Clinical Microbiology and Infectious Diseases. My interdisciplinary research is focused on Infection Prevention and Control (IPC) and development of sustainable Molecular Diagnostics (using novel technologies) to help tackle the Global Healthcare Challenge of Anti-Microbial Resistance (AMR). My research group is based within the Frontiers in Discovery Science research theme in the Plymouth Institute of Health and Care Research.

I am a recognised national expert in Anti-Microbial Resistance and my knowledge exchange and policy activities contribute to help policy makers and the wider public enhance their understanding of AMR. I am passionate about public engagement and I regularly provide expert commentary in the areas of Infectious Diseases, COVID-19 transmission and AMR in local, national and international media. I sit on the Microbiology Society Council and the Science Committee Board of Antibiotic Research UK.

Dr Joshi's professional YouTube Channel.

Background: After obtaining my BSc in Microbiology at Cardiff University, I completed my PhD in Molecular Microbiology (development of Biosensor Diagnostics for infections) at the Welsh School of Pharmacy, Cardiff University and patented the findings. I subsequently undertook several multidisciplinary Postdoctoral projects exploring commercial development and translation of these biosensor technologies in collaboration with microwave engineers at Cardiff School of Engineering and with Industry partners. I translated the technology to detect a wide range of clinical pathogens while gaining teaching experience. In August 2017 I joined the University of Plymouth as a Lecturer in Molecular Microbiology and was promoted to Associate Professor in August 2022. I have successfully built an independent research group and strong national and international collaborations focusing on developing point-of-care Microbial Diagnostics for AMR and Infection Control. I am a very strong advocate for feasible incentives to promote Equality, Diversity and Inclusion (EDI) in Academia and Microbiology.

Lead for the Microbial Diagnostics and Infection Control Research Group.

Lead for the Microbial Diagnostics and Infection Control Research Group.

Rapid point of care detection of Antimicrobial Resistant (AMR) bacteria

Tina is an expert in the development of novel ultra-rapid point-of-care diagnostics for detection of infections. Her research was featured on BBC One's "The Truth about Antibiotics" in 2019. She is developing an international reputation of excellence within this area. Tina's multidisciplinary experience (<15 years) lies specifically in the areas of novel microwave-enhanced rapid diagnostics for microbial detection and DNA extraction, combined with the newest developments in molecular biology. She honed these multidisciplinary skills during her Ph.D placement at the Institute of Fluorescence at the University of Maryland, Baltimore County, USA with global experts in novel rapid diagnostics. 

Tina's Areas of expertise include: Clostridioides difficile, Bacillus anthracis; AMR pathogens; Field effect transistors (FETS), thin-film transistors, application of Microwave engineering to molecular biology, aptamer design, aptamer-functionalisation of nanoparticles, microwave-accelerated metal enhanced fluorescence, microbial bioinformatics and biosensor development. 

Infection Prevention and Control & Microbicides

Tina has a strong interest in infection control and this research looks to understand how biocide use can affect the genomic and phenotypic properties of viruses, bacteria and spores. A key theme is Clostridioides difficile spore persistence and transfer across fomites and clinical environments. 

Tina's Areas of expertise include: Category 2 &3 pathogens, biocide testing, molecular microbiology, DNA sequencing, industry collaborations. Tina also provides expert consultancy in these areas.

Other research

Community Engagement

Tina is passionate about public engagement and knowledge mobilisation. During the COVID-19 pandemic Tina regularly provided voluntary expert information about infectious disease transmission via broadcast media (BBC Spotlight, BBC Radio Devon & BBC Radio Cornwall) to support her local Community in the South West. 

Recently she collaborated with local Plymouth charities to produce infection control and hygiene learning resources for adults with learning difficulties. She is collaborating with the School of Psychology & School of Art, Design & Architecture to examine impacts and public opinions of AMR and COVID-19.

Other academic activities

Media & Public Engagement:

I have strong engagement with the media in promoting the understanding of antimicrobial resistance and COVID-19. This includes newspaper articles, blogs, online social media, radio and national television. I provide expert commentaries via live broadcast on BBC Spotlight, BBC Radio Devon and BBC Radio Cornwall. My research and expertise has been featured and sought for in blogs, newspapers and international documentaries, including the "End of Medicine" directed by Alexander Lockwood, produced by Keegan Kuhn; Executive Producers Joaquin Phoenix and Rooney Mara.

Additional information

I am a strong advocate for promoting STEM with the aim of encouraging interest in studying these subjects. I am part of "Inspiring the Future" and am a STEM Ambassador. I continue to mentor students with their prospective scientific career choices and am heavily involved in varying Women in Science mentorship schemes. I am interested in advancing equality across HE, specifically with regard to race equality (Race Equality Charter) and gender equality through the Athena Swan Charter. 

I am a Mentor in the Pardesi Mentorship Programme which supports South Asian Women globally.
