ELIZABETH GEORGE (Research Scientist)
​
I am broadly interested in the causes and consequences of animal social behavior. I completed my PhD with Dr. Kimberly Rosvall at Indiana University, where I studied behavioral and physiological responses to female-female competition in tree swallows. I then did a postdoc with Dr. Courtney Fitzpatrick at Texas A&M University, where I explored patterns of female reproduction in yellow baboons. Most recently, I have been working with Dr. Gerry Carter at OSU and Princeton University to study the social behavior of common vampire bats. In the Hellmann lab at OSU, I will be studying the effects of the social environment and predator exposure on females' physiological responses and the growth and survival of their offspring. In general, I am passionate about engaging with undergraduate and graduate students at all stages of the scientific process to mentor budding scientists. I also enjoy birdwatching and wildlife photography.

MICHAELA ROGERS (PhD student)
​
Overall, I seek to understand the conditions under which adaptive transgenerational plasticity occurs. My research focuses on the impact that different types of predator cues (visual, olfactory) have on the next generation's fitness. A secondary interest lies in the connection between predator exposure and immune response.

TRUTH MULLER (MS student)
​
I seek to understand the transgenerational effects of social interactions between conspecifics. My current research focuses on the impacts of competition between K. marmoratus parents on their offspring. I also have strong interests. environmental education, science communication, and the behavior and development of marine invertebrates.
​
SIDNEY RYAN (PhD student)
​
I am interested in the ability of organisms to adapt to changing environments within their lifetime and the mechanisms that underly that adaptation. My previous work has included investigating the homing abilities of nesting male Threespine Stickleback in Vancouver Island, British Columbia and studying a lineage replacement event of the extinct Threespine Stickleback counterpart G. doryssus in a late Miocene lakebed.

CAITLIN WEID (PhD student)
​
I seek to understand the transgenerational effects and consequences of multiple stressors. I also have a soft spot for all things marine and spineless (marine inverts!)
