Operations Manager

Dr Ciara O’Donovan

Ciara completed her BSc in Nutrition and Health Science at the Cork Institute of Technology. She completed her PhD in Microbiology with University College Cork where her focus was on elucidating the microbiome of Irish athletes.

During this time she focused on the investigation of several parameters on the gut microbiome of athletes. During her subsequent postdoc her research focused primarily on the microbial composition and activity within fermented food environments.


Marcus O’Brien

Marcus completed his BSc in Microbiology and MSc in Bioinformatics in University College Cork. He has worked on projects involving Parkinson’s disease, Listeria and Chlorella.

He is currently working as a Bioinformatician for SeqBiome, performing analysis on genomic, 16s and metagenomic data on a wide array of microbiomes.


Dr Shriram Patel

Shriram completed his BSc, MSc and PhD in Biotechnology in Sardar Patel University, India. He has extensive microbiome analysis experience in studying host and microbial interactions of various ecosystems.

In addition to analyzing a wide array of microbiomes for SeqBiome, his research interests includes the role of the microbiome and host genetics in coeliac disease.

Laboratory Technician

Ramya Balasubramanian

Ramya has an undergraduate degree in pharmacy and a MS in Pharmacology and toxicology. She is a PhD student at UCC and Teagasc. Ramya’s current research question aims at developing an understanding of the impact of diet on the microbiota-gut-brain axis.

She is also looking at key microbial players and their metabolites that possess neuromodulatory abilities, which can influence gut to brain communication. This work would be in line with microbiome targeted therapeutics that are aimed at the mental health and overall wellbeing of the consumer.

Laboratory Technician

Emmanuel Osei

Emmanuel completed a BSc in Biological Sciences in Ghana following which he worked as a research assistant for a year with focus on bacterial pathogens and helminths. He completed his MSc work in bacteriophage therapy at the University of Leicester, UK.

Emmanuel is a lab technician with SeqBiome while working towards his PhD. His research focuses on microbial genomics and the application of synthetic biology in developing phage-based biocontrols.

Laboratory Technician

Laura Finnegan

Laura graduated with a BA in Human Genetics from Trinity College Dublin, after which she worked for four years as technician on the Teagasc sequencing platform and is now working with SeqBiome and towards a PhD in Microbiology in University College Cork.

Laura’s primary research focus is on developing next-generation sequencing tools and methods, with a view to improving the application of the technology to microbiome studies and to enhance understanding of the role of the microbiome in food and human health.

Laboratory Technician

Vinicius Pedrosa

Vinicius graduated with a BSc in Biotechnology from Federal University of Uberlandia (UFU) in Brazil. He also did part of his bachelor’s degree at the University of Western Australia in Perth for two semesters. He is currently working at SeqBiome as Laboratory Technician where he is responsible for DNA extraction and libraries preparing.
