I coordinate the Finnish common bird monitoring schemes and lead my research group the Helsinki Lab of Ornithology in the Finnish Museum of Natural History. I wrote my first bird observations in year 1987. I started my biology studies in 1999 and finished my MSc thesis about population dynamics and diet of the Great Cormorant in 2003. In my PhD thesis (2009), I studied impact of climate and food availability on timing of breeding and breeding success of eight bird species. I have been working in the Finnish Museum of Natural History since November 2009. I'm also a board member of the European Bird Census Council and a member of the Finnish Nature Panel ( in Finnish). I am also an active ringer and observer at the (website in Finnish).

In my PhD, I am exploring the effects of agriculture and climate change on farmland biodiversity indicators, with a focus on birds and butterflies. Through this, I aim to be able to direct conservation strategies and policy making. My thesis supervisors are Johan Ekroos, Aleksi Lehikoinen and Laura Bosco and I am funded by the Wihuri foundation. During my free time, I can be found volunteering in or popularizing science such as through writing nature articles into kid’s magazines.

I am a researcher at Helsinki Lab of Ornithology HelLO, where I have been working since 2020. My research focuses on understanding avian responses to climate and land-use changes in relation to habitat loss and fragmentation at various spatial scales. I am particularly interested how landscape ecological aspects play into species responses to global change. I graduated in 2018 from the University of Bern (Switzerland) where I researched effects of vineyard management and landscape structure on Woodlarks and their arthropod prey. Afterwards I worked at the Swiss Ornithological Institute as scientific collaborator in a project on increasing vineyard biodiversity in southern Switzerland. I am President-Elect of the  since 2024, chair of the  and board member-at-large of the . For the BES journal , I have been contributing as an Associate Editor since 2023.

I started my PhD thesis at the beginning of 2022. My project aims at understanding altitudinal shifts in avian communities under climate change across European mountains and the implications for the conservation. The project takes a macroecological approach to understand the broad impacts of climate change on species communities. My thesis is supervised by Aleksi Lehikoinen, Emma Marjakangas and  Andrea Santangeli and is funded by the Kone Foundation. During my free time, I like to knit sew and walk in the nature.

I’m a postdoctoral researcher working with avian acoustics in the HelLO and . I did my PhD in HelLO in 2016-2020, although situated at the Lund University as a visiting researcher, and joined the group again in 2025. In my PhD, I studied how conservation measures benefit birds in responding to changes in climate and land use. At the moment, I study how visitor pressure affects bird communities in National Parks, using automated bird sound identification and novel citizen science tools. Otherwise, I’m widely interested in avian ecology, e.g. enhancing conditions for waterbirds through wetland restoration. I coordinate  in Finland. I’d like to find myself more often immersed in bird monitoring and ringing, fishing, taking my dogs to lure coursing and above all hiking in montane tundra.

I'm an ecologist who graduated from the University of Helsinki in 2020 and I started my PhD in the Helsinki Lab of Ornithology in 2022. In my work, I investigate how population dynamics of European birds are affected by survival and productivity by analyzing European long-term bird ringing datasets of . I aim to deepen the understanding of the population dynamics of European birds for better conservation planning and implementation. My work is supervised by Aleksi Lehikoinen, Laura Bosco, and Markus Piha and funded by . In my free time, I like watching birds and exploring nature.

I began my PhD in the Helsinki Lab of Ornithology in 2025. My research aims to examine cumulative responses of avian species to climate change and determine how those responses vary spatially and seasonally. My thesis is supervised by Aleksi Lehikoinen, Laura Bosco, Yanjie Xu, and Emma-Liina Marjakangas. Prior to starting my PhD, I completed my master’s thesis at Ohio State University in the USA studying drivers of spring phenology in the Prothonotary Warbler. Outside of work, I enjoy writing stories, reading novels, and hiking.

I coordinate the 100 Species Challenge , a citizen science project led by Aleksi Lehikoinen. The challenge encourages participants to observe and identify at least 100 species of plants, insects, or fungi within a year. Our goal is to inspire people to explore nature, improve their species identification skills, and potentially become lifelong citizen scientists. I joined the project and HelLO in early 2024, shortly after completing my master’s degree in ecology and evolutionary biology at the University of Helsinki. My role involves communicating with participants and sharing information about the challenge and Finnish species through social media, outreach events, and various media outlets. The project is funded by Kone Foundation.

I started my PhD project in 2023. In my project I study bats in a boreal setting, specifically trying to identify possible latitude-dependent factors that influence bat activity. My questions focus on habitat use, predation (bottom-up and top-down) and weather. I am using acoustic technology and passive ultrasound recorders to record echolocation calls and collect activity data on a large spatio-temporal scale across Finland. My thesis is supervised by Thomas Lilley and Aleksi Lehikoinen and funded by Societas pro Fauna et Flora Fennica.

I am doing my PhD in the . 

Before my PhD journey I was coordinating the Complete checklists -project, which is a part of BIOMON program for monitoring biological diversity. Complete checklists -project aims to collect monitoring data in particularly on common species from different taxa, such as plants, mushrooms, amphibians and reptiles, and various insect groups.

I am a macroecologist broadly interested in different research topics on macro-spatial ecological dynamics. I currently work in the Finnish Environmental Institute, but I hold a visiting researcher position in Luomus, where I am supervising PhD researchers in the HelLO. I joined HelLO from 2020 and have been working on climate-driven dynamics of wildlife and zoonotic diseases in European birds and bats; pan-European conservation prioritization for birds under global change; waterbird diversity and abundance trends with wetland restoration practices in Finland. Before joining HelLO, I worked on connectivity of global bird migration networks and defended my PhD thesis entitled ‘Unravelling Networks: Causes and Consequences of Decreasing Connectivity in Bird Migration Pathways’ at Wageningen University & Research (the Netherlands).
