Effect of anthropogenic sound on aquatic life

Using playback experiments to see how oyster toadfish respond in their calling to both anthropogenic sound (vessel engine) and the calls of other toadfish. This work is in collaboration with Alayna Mackiewicz (a PhD candidate at the University of North Carolina Chapel Hill) and Nora Curtis (an undergraduate at the University of Minnesota Duluth).

Sensory physiology

I have been investigating the effect of eugenol as an alternative anesthetic when performing neural experiments on fishes. Using oyster toadfish (Opsanus tau) as my model organism, I used electrophysiology to record the neural activity of the lateral line when exposed to a vibrating sphere and see if the reaction is suppressed under anesthetization. This work is in collaboration with Loranzie Rogers (a PhD candidate at the University of Washington).

Soundscape ecology under ice and open water conditions

I have been involved in numerous passive acoustic monitoring studies both in temperature reef systems (New Zealand) and in freshwater lakes (Minnesota, USA). I investigated the sounds produced by geological, biological and anthropogenic activity and how soundscapes changed over temporal and spatial patterns.
