My research concerns taxonomy, systematics and evolution of birds, especially Asian passerines.

Avian tree of life
I use molecular data to reconstruct the phylogeny ("tree of life") of different groups of birds. I have been involved in comprehensive studies of multiple avian families, which have revealed previously unexpected relationships and complex evolutionary patterns; e.g. Emberizidae (Alström et al. 2008), Acrocephalidae (Fregin et al. 2009), Muscicapidae (Sangster et al. 2010), Cettiidae (Alström et al. 2011), Locustellidae (Alström et al. 2011, Alström et al. 2018), Alaudidae (Alström et al. 2013, Alström et al. 2023), Cisticolidae (Olsson et al. 2013), Prunellidae (Liu et al. 2017), Phylloscopidae (Alström et al. 2018), the 2–7 ‘babbler’ families (depending on taxonomy; Gelang et al. 2009, Cibois et al. 2018, Cai et al. 2019), Laniidae (Fuchs et al. 2019) and Estrildidae (Olsson & Alström 2020), and the superfamily Sylvioidea (Alström et al. 2006, Fregin et al. 2012; review paper: Alström et al. 2013) and the large Passerida clade (including description of a new family of birds: Alström et al. 2014), as well as the first genomic-level studies of all passerine families (Oliveros et al. 2019) and all avian orders (Jarvis et al. 2014).

I have also been involved in phylogenetic and/or phylogeographic studies of smaller groups, such as genera of parts of genera, e.g. Acrocephalus (Olsson et al. 2016), Aegithalos (Wang et al. 2014, Zhang et al. 2017), Anthus (Alström et al. 2015), Alaudala (Ghorbani et al. 2020), Calandrella (Stervander et al. 2016), Cyornis (Zhang et al. 2016, Singh et al. 2020), Eremophila (Ghorbani et al. 2020), Ficedula (Hooper et al. 2016), Heteromirafra (Spottiswoode et al. 2013), Larvivora (Zhao et al. 2017), Motacilla (Alström et al. 2015, Li et al. 2016, Harris et al. 2018), Phylloscopus/Seicercus (Irwin et al. 2001, Olsson et al. 2004, Olsson et al. 2005), Pica (Song et al. 2018), Scotocerca (Alström et al. 2011), Tichodroma (Zhao et al. 2016), Turdus (Nylander et al. 2008) and Zoothera (Olsson & Alström 2013).

Taxonomy of birds
I use an integrative taxonomic approach, involving analyses of e.g. morphology, vocalisations, behaviour, DNA, ecology and geographical distributions, to study the taxonomy of birds. These studies have resulted in a significant increase in the number of recognised species in the studied groups, including the description of seven new species and three new subspecies to science. E.g. within the genera Acrocephalus, Alaudala (Alström et al. 2021), Brachypteryx (Alström et al. 2018), Calandrella (Alström & Sundev 2021; Stervander et al. 2020; incl. new subspecies: Calandrella cinerea rufipecta), Carpodacus (Liu et al. 2020), Calliope (Liu et al. 2016), Cyornis (Zhang et al. 2016, Gwee et al. 2019, Singh et al. 2020), Emberiza (Olsson et al. 2013), Eremophila (Ghorbani et al. 2020), Ficedula (Dong et al. 2015), Horornis/Cettia (Alström et al. 2007, Wei et al. 2019), Lanius (Olsson et al. 2009), Locustella/Bradypterus (Alström et al. 2008, Alström et al. 2015, incl. new species: L. chengi), Motacilla (Duckworth et al. 2001, new species: M. samveasnae), Mirafra (Alström 1998), Phylloscopus/Seicercus (Alström & Olsson 1990, Alström & Olsson 1992, Alström et al. 1993, Olsson et al. 1993, new specie: P. hainanus; Alström & Olsson 1995, new species: P. emeiensis; Alström et al. 1995, Alström et al. 1997, Alström & Olsson 1999, incl. new species: S. soror; Alström & Olsson 2000, Alström et al. 2010, incl. new species: P. calciatilis, Alström et al. 2011, Zhang et al. 2019, Zhang et al. 2021), Pica (Song et al. 2018), Prinia (Alström et al. 2020; incl. new subspecies: P. polychroa deignani; Alström et al. 2021, incl. a new subspecies P. gracilis ashi), Sylvia (Olsson et al. 2013) and Zoothera (Alström et al. 2016, incl. new species: Z. salimalii).

Evolution of birds
I am also very interested in various evolutionary questions, and I have been involved in studies of such diverse subjects as speciation (e.g. Alström et al. 2015, Semenov et al. 2021), evolution of different geographical avifaunas (Johansson et al. 2007, Price et al. 2014, Lei et al. 2015, He et al. 2019, Cai et al. 2020), evolution of vocalisations of some passerine groups (Xia et al. 2013, Xing et al. 2013, Wei et al. 2017), evolution of UV vision in shorebirds (Ödeen et al. 2009) and passerines (Ödeen et al. 2011), biogeography of several groups of birds (Saitoh et al. 2010, Song et al. 2016, Liu et al. 2017, Song et al. 2020), pitfalls of comparisons of genetic distances (Fregin et al. 2012), species concepts (Alström 2006), and genome evolution (Zhang et al. 2014). These studies have used an array of data, e.g. phylogenetic, morphological, ecological, paleoclimatic, and distributional (including “big data” from e.g. GBIF), and a plethora of analytical methods.
