The combined long-term objectives of our research are to better understand the molecular, genetic, and cellular mechanisms causing neurodevelopmental and neurological disorders. Overall, my research interests lie primarily in the study of disorders of brain development and neurological disease, and specifically involve the following areas of investigation:

1) functional analyses of AHI1 and CSPP1, two novel genes which we mapped and cloned in individuals with Joubert syndrome (Ferland et al., Nature Genetics, 2004; Doering et al., J. Comp. Neurol., 2008; Hsiao et al., Hum. Mol. Genet., 2009; Westfall et al., J. Neurosci., 2010; Tuz et al., J. Biol. Chem., 2013; Tuz et al., Am. J. Hum. Genet., 2014; Bourgeois and Ferland, Dev. Biol., 2019; Munoz and Ferland, J. Cell Sci.; 2019),

2) formation and function of the primary non-motile cilia in development and disease (Hsiao et al., Hum. Mol. Genet., 2009; Westfall et al., J. Neurosci., 2010; Hsiao et al., Cilia, 2012; Tuz et al., J. Biol. Chem., 2013; Tuz et al., Am. J. Hum. Genet., 2014; Hua and Ferland, Cilia, 2017; Hua and Feland, Cell. Mol. Life Sci., 2018; Hua and Ferland, Bioessays, 2018; Bourgeois and Ferland, Dev. Biol., 2019; Munoz and Ferland, J. Cell Sci.; 2019),

3) genetic and neuroanatomical mechanisms of seizure threshold, seizure propagation,  epileptogenesis, and Sudden Unexplained Death in Epilepsy (SUDEP) (Ferland et al., G3 Genes, Genom. Genet, 2017; Ferland, 2017; Loscher, Ferland, and Ferraro, Epilepsy and Behavior, 2017; Kadiyala et al., J. Neurosci., 2016; Kadiyala et al., Epil. Res., 2015; Kadiyala et al., PLoS ONE, 2014; Papandrea et al., Exp. Neurol., 2009; Papandrea et al., Epil. Res., 2009; Ferland et al, 1998a,b,c, 1999, 2002a,b, 2003).
