Biography

I am currently a lecturer of Astronomy and Science education at the University of Southern Queensland.

In this capacity I have worked to diversify the pedagogical outcomes of the courses, creating a diverse

learning experience for students. In the Masters Science courses, I have worked in an interdisciplinary

manner enhancing the intrinsic motivation of students. Throughout the astronomy courses, which range

from undergraduate, to graduate level, I strive to enhance student learning with the latest astronomical

advances. My scientific interest lies in asteroid astrocladisicts and dynamical simulations, for which I have

mentored Masters level students in the exploration there of. In a broader context, I am interested in the

taxonomy and dynamics of Solar system bodies, as well as Exoplanets.
