I am a Lecturer in Mathematics in the School of Mathematics, Statistics and Applied Mathematics at NUI Galway. From 2008 to 2019 I was a member of the AG-Differentialgeometrie in Münster, where I completed my Habilitation under the guidance of Burkhard Wilking. In 2016 I spent a semester as a Research Member at MSRI in Berkeley during the Program on Differential Geometry, while in 2017 I spent a semester in Bonn as Professurvertreter. I received my PhD in 2008 from the University of Pennsylvania, under the supervision of Wolfgang Ziller.

My main research interests are

- Positive and non-negative sectional curvature
- Geometry and topology of homogeneous spaces and biquotients
- Isometric Lie group actions and compact transformation groups
- Rational homotopy theory

I am a founder and organiser of the Irish Geometry Seminar.

I am also an organiser of the upcoming Groups in Galway meets the Irish Geometry Conference.

In the past, I helped organise five iterations of the international Workshop on Curvature and Global Shape in Münster: CGS2019, CGS2017, CGS2015, CGS2013 and CGS2011. I was also an organiser of the conference Representations of Riemannian Geometry, which took place at St. Joseph's University in Philadelphia in August 2017.
