Research Activities in the Brunkow Lab

Many different kinds of research projects have been undertaken in the lab, incorporating many undergraduate and graduate students. Some of these projects have been completed to a greater degree than others; however, all have led to an increased understanding, on my part as well that of my students, of the scientific process and the natural system examined. Projects have been completed in field as well as laboratory settings, sometimes combining both.

Students have always kept the lab vibrant and moving forward, and I see students working in the lab as my greatest asset. For a list of the students who have worked under my supervision or who have been trained or otherwise mentored in the lab, click here.

The links in the right column of the table below highlight only some of the research projects that have been tackled in the lab. They are meant to show the diversity of studies we've examined, the range of techniques and approaches used, and the many ways that students have been integrated into my research activities.
