Current Graduate Students:

2015-       Emily Kiehnau (B.S. Lawrence University 2015; current Ph.D. student)

Emily Kiehnau holding a Glew gravity corer for sampling sediments in the Muskoka Lakes, Ontario, Canada  July 2016.

Emily’s research focuses on quantifying the plastic and evolutionary responses of native species to exotic introduced species and on identifying how these responses influence community level processes. She has been studying the exotic introduced zooplanktivore, Bythotrephes longimanus (a.k.a. spiny waterflea).  This species is a threat to pelagic biodiversity of North American lakes because of its heavy predation on native zooplankton, particularly Daphnia. Of the many Daphnia species found in North American lakes, only D. mendotae appears to thrive in the presence of B. longimanus. Emily’s research centers around identifying the antipredator response of Daphnia species to Bythotrephes via a variety of behavioral and morphological kairomone (i.e., chemical cue) studies conducted on pre- and post-invasion Daphnia populations.


2018-        Matt Wersebe (B.S. SUNY-Binghamton 2018) – Matt will be joining the lab in August 2018.


Current Undergraduate Students:


2017-2018  Ritu Kulkarni  (B.S. Honors – U. of Oklahoma)

Ritu Kulkarni – Honors B.S. (Microbiology)

Ritu joined our lab in fall 2017.  She has taken Honors Reading and is currently conducting Honors Research.  Her Honors Research project has been  focusing on the interactions between food quality and predator kairomones on the life-history features of Daphnia pulex, D. pulicaria, and an experimentally-created hybrid clone between these two parental species. 


2018-2019 Kristina Floyd (B.S. Honors, U. of Oklahoma)

Kristina has been working as a summer Undergraduate Research Assistant (UGRA) for summer 2018 in our lab.  She will begin her Honors Thesis project in fall 2018.


2018-2019 Ekene Nwakoby (B.S. Honors, U. of Oklahoma)

Ekene will be joining the lab in fall 2018.


2018-2019 Brandon Day (B.S., U. of Oklahoma)

Brandon will be joining the lab in fall 2018.
