Dr Harisree Paramel Nair

Postdoctoral Research Associate

Associate Lecturer

Faculty:Faculty of Science and Engineering

School:Life Sciences

Location: Cambridge

Areas of Expertise: Microbiology

Harisree is a molecular microbiologist with interest in environmental microbes and zoonotic pathogens. Her previous research focuses on culture-based and culture-independent analyses of microbial communities in marine and mangrove ecosystems and in mud volcanic sediments. Harisree’s current research focuses on antimicrobial resistance (AMR) in wild birds and the environment.

View Harisree’s profile on ResearchGate


Harisree obtained her PhD from Cochin University of Science and Technology (India) in 2016 for her research investigating the metagenome of marine and mangrove sediments, particularly focusing on phylogenetic diversity and characterisation of amylase obtained by functional screening. During her doctoral research, she also worked as a junior and senior research fellow in a Govt. of India funded research project to study the metagenome of marine sediments. Later, she joined the Indian Institute of Science as a postdoctoral fellow until 2018.

She joined Anglia Ruskin University in 2019 and started working alongside Joana Rodrigues and under the guidance of Dr Caray A Walker. Their research group is focused on researching the prevalence of enteric pathogens in wild birds and investigating potential antimicrobial resistance mechanisms and virulence factors. The Walker group works in collaboration with a number of wildlife trusts and rescue centres across England in order to complete their research. We are always actively looking for new collaborators in these areas.
