Lecturer in Molecular Microbiology (Teaching and Research) 

Lead for Microbial Diagnostics and Infection Control Research Group 

Employability Co-ordinator for School of Biomedical Sciences 

After completing BSc and PhD studies at Cardiff University, I undertook several postdoctoral roles from 2012-2017 before commencement of a Lectureship at the University of Plymouth. I specialise in infection control of clinically-relevant bacteria (Clostridium difficile) and development of molecular diagnostics for antibiotic resistant organisms.

Recently our research into Clostridium difficile spore resistance to chlorine and persistance on hospital gowns has made UK and international news. The paper has been published in Applied and Environmental Microbiology (2019).

In 2018 I was awarded the Hind Rattan "Jewel of India" Award from the Indian Government (Non-Resident Indian Welfare Society of India) for diasporal achievements in academia within the country of my birth - the UK.

Research interests

Described in detail on Tina's research pages:


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 (recently featured on BBC One's "The Truth about Antibiotics"). She is developing an international reputation of excellence within this area.

Tina's wealth of experience (<10 years) lies specifically in the areas of novel microwave-enhanced rapid diagnostics for microbial detection, combined with the newest developments in Molecular Biology. She has honed these multidisciplinary skills from commencement of her PhD (2008-2012) where she worked at the Institute of Fluorescence at the University of Maryland, Baltimore Country and with global experts in novel rapid diagnostics.

Areas of expertise include: Field effect transistors, 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 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 bacteria/spores. A key theme is Clostridium difficile spore transfer across clinical environments and resistance to chlorine disinfection.

Other research

Other interests include:

Bacillus anthracis decontamination and detection in the field.

Research degrees awarded to supervised students

Tina has successfully and independently supervised both undergraduate and postgraduate students. Applications for PhD research in Tina's areas of expertise are welcomed. Please email: tina.joshi@plymouth.ac.uk

Additional information

I am a strong advocate for promoting STEM with the aim of encouraging interest in studying these subjects.
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 at the University of Plymouth. I also work with Charity Well Connected to promote dental hygiene and antibiotic awareness.
