Esmeralda Herrero BSc. PhD


Esmeralda Herrero graduated from University College Dublin (UCD) with a BSc in Pharmacology and completed a PhD in Microbiology in University College Dublin. Her research investigated bacterial proteases and their role in prion decontamination and was filed into a UK patent in 2015. Following her PhD, Esmeralda worked for a year as research and development scientist for a novel biotech company before her role as scientific officer in virology in airmid healthgroup.

Esmeralda has over 5 years research experience in mammalian cell culture, molecular biology, bacterial culturing, infectious assays, protein purification, protein biochemistry and laboratory management


Tristan Russell BSc. PhD


Tristan graduated from the University of Leeds with a BSc in Microbiology. During his degree, Tristan completed a one-year internship at a pharmaceutical company where he gained experience of working in an industrial laboratory. Tristan moved to Ireland in 2014 after choosing to study for a PhD at University College Dublin. The PhD research used molecular biology techniques to study infectious disease, specifically host-virus interactions. Tristan recently graduated from his PhD and joined the virology team at airmid healthgroup in the spring of 2019.

Kevin is in his third year at DCU where he has been studying Genetics and Cell biology. He is working in the Environmental Chambers under the supervision of Jake Behan.


30m3 Environmental Test Chamber Specifications

The 30m³ environmental test chamber is constructed from low emitting and low polluting powder-coated insulated steel panels, based on the requirements in the following standards ASTM D6670-01, ANSI/AHAM AC-1:2006, JEM1467 and GB21551 3. The test chamber has HEPA filtered supply and exhaust air, along with recirculating ceiling and wall fans. The air in the test chamber can be conditioned to a broad range of temperature and relative humidity settings. The test chamber also has an independent air circulation system, which enables the control of the number of air changes per hour from as low as 0.10 to 1.0 and above. The ante-room is also supplied with HEPA filtered air, which is maintained at a positive pressure of approximately 20 kpa. UV lamps are used to sterilize the chamber environment. The air is supplied can be purged from the chamber enabling an air purity level after cleaning to be considerably above class 10,000.

Specialist monitoring instrumentation measures concentrations of suspended particulates and the levels of other harmful airborne pollutants such as allergens, viruses, mold, bacteria, volatile organic compounds (VOCs) and formaldehyde. Air samples can be collected remotely via sample ports at designated time points.

Our chambers are located in the centre of our facility and are surrounded by our molecular biology, microbiology, mycology, virology and allergen laboratories, thus allowing air and surface samples generated in the chambers to be rapidly processed and analysed.
