Current Committee Members

Ashleigh Kitchiner (Chair)

Ashleigh KitchenerAshleigh is a passionate marine biologist and environmental advocate. She is educated formally with a BSc. (Hons) Biology and MRes Marine Mammal Genetics from the University of Chester, UK. She conducted research utilising stranding data to compile population genetics of long-finned pilot whales (Globicephala melas) across the UK. She has been fortunate enough to work in the energy, NGO and tourism sectors, working offshore in various roles. Ashleigh is passionate about onboarding environmental advocates and has developed and delivered webinars, conferences and, training courses at all levels.

She now works as a consultant and her main areas of expertise are marine mammal ecology, policy and legislation, impact assessments and acoustics. Ashleigh is a commercially-minded research-driven individual and would like to bring her experience to the Marine Mammal Observer Association (MMOA) executive committee to create a network of empowered Marine Mammal Observers (MMOs) and professionals internationally.

Carolyn Barton (Stone) (Vice-Chair)

Carolyn Barton (Stone)Following a PhD on barnacles, Carolyn spent 5 years with the JNCC's Seabirds at Sea Team but has spent the last 25+ years working in MMO-related areas.

She has substantial experience working as an MMO covering seismic surveys, drilling, dredging and pile-driving operations. She has been an accredited MMO trainer since 1996 and has trained over 3000 MMOs. Carolyn has also been involved in the development of mitigation measures and data recording protocols. She has created and analysed JNCC's database of MMO data from UK waters, including analysis of a 25-year dataset to examine the effects of geophysical surveys on marine mammals and compliance with the JNCC guidelines.

Carolyn recognises the importance of maintaining professional standards and is pleased to have served on the MMOA committee since 2007.

Mike Ambler (Treasurer)

Mike AmblerMike completed an undergraduate degree in Aquatic Biology from the University of Aberystwyth and then went on to gain an M.Sc. in Applied Hydrobiology from the University of Cardiff.

After a spell as a biologist with the Environment Agency Wales, Mike trained to become a teacher and was employed as a secondary school science teacher for almost a decade, before moving into the offshore consultancy business in 2010. Mike is now an experienced Marine Mammal Observer, PAM Operator and Environmental Scientist and has undertaken many offshore projects around Africa and Europe.

Mike has conducted marine mammal surveys for MARINElife in the Bay of Biscay, and devotes a lot of his onshore spare time to conservation work with the Wildlife Trusts. Mike has been a full member of the Marine Mammal Observer Association for the past five years and joined the Executive Committee in 2016.

Patrick Lyne

Patrick LynePatrick Lyne has worked in mitigation for 11 years and been involved with the MMOA committee for seven years. Patrick is committed to improving standards of mitigation at a regulatory and MMO (and PAM) level. Industry contraction has affected everyone and perhaps the standards in mitigation more so. However Patrick hopes things will change and would like to see a shutdown employed in all mitigation procedures where an injurious level of sound is used.

He would also like to see experience as part of requirements in future work, such that one MMO and PAM operator on the mitigation team has some credible expertise.

Neil Niru Dorrian

Neil Niru DorrianNiru is a Senior Offshore Ecological Coordinator and Marine Mammal Biologist. He is a Fellow and Chartered Marine Scientist through the IMarEST, a Chartered Scientist through the Science Council, and a certified Environmental Clerk of Works. With over 18 years´ experience over multiple international projects specialising in marine mammal and protected species fieldwork, environmental mitigation & monitoring, permitting, EIA, project management, advisory services, conservation, animal rescue, and pathology. 

He is also a Co-Founding Director at Whalefish, an international non-profit marine conservation organisation, and Co-Chair of the IMarEST Marine Mammal Special Interest Group. In 2018, Niru received the IMarEST Outstanding Contribution Award – Marine Ambassador, recognising his work as an individual who has made a significant contribution to advocacy, communication, outreach, policy, and public service in the marine sector. 

Niru is passionate about driving positive and progressive changes in environmental sectors while maintaining professional standards and improving science communication.


Denis Kovshov

Denis KovshovDenis is a skilled marine environmental consultant experienced in research and protected species mitigation and environmental sampling. Having worked extensively investigating the distribution and abundance of the IUCN Gray whale population in the shallow waters of Sakhalin Island with Shell and Exxon since 2008, he then moved on to work in the United Arab Emirates with ADNOC since 2019.

He is familiar with behavioral responses and veterinary examination being involved in various projects. He has accrued over 10 years of work experience undertaking a variety of marine environmental surveys and advisory projects for the offshore sectors.

He specialises in Marine Mammal Surveying for Baseline and Environmental Impact Assessments, advisory services, conservation outreach, crew briefing and operational standards.

Justin Judge

Justin Judge

Justin works as a Discipline Lead and Subject Matter Expert on Marine Mammals and Sea Turtles, Senior Marine Mammal Observer and Board Member for several NGOs. He has strong interests in functional ecology, conservation biology, conservation management, marine mitigation and MPAs. Justin completed his PhD in marine food web dynamics in 2020 and actively seeks to apply his findings across many different trophic levels in marine systems. Justin's expertise lies in investigating the effects of anthropogenic and natural perturbations in ecosystems as well as providing associated mitigation services.

Regarding the latter, Justin has worked as a Marine Mammal Observer for 8 years and has been involved in numerous domestic and international projects.
