My research focuses on the evolution of human cognition, specifically primate comparative research on communication, language, and tool use behaviors.

PhD Mom: Baby development

Posted by

I’ve been doing this mom thing for about 2 years now and along the way I’ve gotten a chance to not only watch my child grow from being a squishy potato of a newborn into a boisterous, opinionated, and hilarious toddler, but I’ve also learned some cool things about baby cognition and child development along the way…

#PrimatesAreNotPets: A social media animal welfare campaign

Have you ever seen “#PrimatesAreNotPets” floating around Twitter and other social media platforms? There’s a good reason this hashtag is becoming more prominent on the internet; primatologists, animal welfare activists, and conservationists are pushing to bring attention to the illegal pet trade and the devastation that it wrecks on the animals and their natural habitats. Primates aren’t the only exotic animals affected by the illegal pet trade, but they provide an excellent example of what removing a species from an ecosystem can do both at home and in the wild…

Back to the Stone Age: Monkey see monkey do

Primate archaeology is a fast growing field. While archaeology usually refers to the study of the human past through the excavation of past tools, remains, and civilizations, primate archaeology unearths the technological (tool use) past of our primate relatives as well as observes tool use by primates in real time. Each year, scientists make new discoveries about primates and their behaviors that prompt questions about the full extent of our primate relatives’ cognition and how it relates back to our own cognitive evolution…

What you might not know about keeping animals: Misconceptions about zoos

Zoos, aquariums, and animal sanctuaries are really important because they support animal conservation, species survival, insightful animal research, and educational programs.  However, there’s a lot of misinformation and misconceptions about zoos and animal sanctuaries that animal activists, such as PETA, use in order to deter people from enjoying, learning from, and supporting facilities that house wild animals…

PhD Mom: A day in the life

Today, we’re going to talk about the typical day of a PhD parent – mom addition – except I don’t have a “typical” day. Instead, I have a three-and-a-half month old, Percy, who is teething and going through the four month sleep regression early, so no sleep for baby and no sleep for me. If I’m lucky, I’ll be able to run downstairs in the morning – normally, a little bit before 7 a.m. – to start making my breakfast. Before it’s even ready, my son will wake up from his last nighttime sleep session. Before eating my oatmeal and drinking my tea, I’ll go back upstairs and change him out of his pjs and dirty diaper. When infants don’t feel well (like when teeth are forcing their way through their gums), they tend to get clingy, so he’ll sit on my lap while I eat breakfast…

Where did all the jobs go?

I was recently re-watching an episode of The Big Bang Theory, where the unfortunate passing of a colleague opened up a tenured position in the department that Sheldon, Raj, and Leonard were all vying for. While most people would find their various tactics to shmooze the tenure committee funny, the part that I found most hilarious was a tenure line being maintained instead of turned into cheaper, temporary adjunct positions. In reality, tenure is a dying position in academia, and it’s severely impacting the job market…

Welcome to the Weaver Lab: An interview with Dr. Lesley Weaver

Dr. Lesley Weaver, an alum of IU’s Department of Biology, has returned to campus as an Assistant Professor after her finishing her postdoctoral research at Johns Hopkins University. This past September, I had the opportunity to interview her about her experience as an early career researcher, setting up her lab, navigating IU in her new role as an Assistant Professor, and how the COVID-19 pandemic shift to online has simultaneously highlighted issues with and solutions to accessibility and diversity in academia.

Science with Nemo: Ethics of Care in Animal Research

Posted by

[animated GIF of seven tropical fish of various kinds, who are all in plastic bags, floating in the ocean. The image captions one fish, speaking, who asks the group, “Now what?”]

We are all familiar with the plot of Finding Nemo: a scuba-diving dentist takes a small clownfish, Nemo, from a reef, keeps him in a fish tank in his office, and Marlin (Nemo’s father) goes on a whirlwind adventure to rescue his son. Obviously, Disney’s creative fiction is just that — fiction. However, many millions of fish are kept in tanks in the real world, for both recreation and research. Although we cannot know the fate of home-kept fish, for fish used in scientific research, there are specific rules for ethical treatment and proper care for fish of all kinds. How and why do scientists use fish in research anyways? 

What social media has taught me about science

Science communication on social media largely happens through Facebook, Instagram, and Twitter (you can find the ScIU blog on all three platforms), but in reality, it extends beyond these three primary sites into platforms such as TikTok, Reddit, YouTube, and more. On any one of these platforms, people from around the world are able to form digital communities where they can talk, educate, learn, advocate, and make new friends. I have been the Social Media Chair for ScIU for over a year now, and in that time, I have learned quite a lot about science communication from social media.
