I have always appreciated the depth and emotion portrayed within the film Perks of Being a Wallflower, which hits on uncomfortable issues in a beautifully cinematic way. While there are a multitude of scenes Icould analyze, I’d like to focus on a clip towards the very end of the movie, in which Charlie (the main character) experiences a flashback that, in my interpretation, can be attributed to post-traumatic stress disorder, or PTSD…

The brain and moral decision making
How do we separate right from wrong in moral decision making? Some moral decisions, like whether or not to commit murder, seem like easy and intuitive moral decisions. However, we are often caught in moral dilemmas in our lives where the “right” thing to do is not as clear…
Debunking myths about therapy
Embarking on the journey of mental health therapy can be a truly transformative experience. However, it’s not uncommon for misconceptions to cloud the path to healing. Despite the increasing demand for mental health treatment, persistent myths still predominate. But here’s a spoiler alert: Therapy isn’t merely about sitting on a couch (or lying down) and pouring your heart out. It’s a dynamic process that goes beyond stereotypes…
Philosophy and moral decision making
Should you cheat on your exam to get a good final grade in your class? When is it okay to lie? If your child is going for an internship at your company, is it morally permissible to give them a leg up over other applicants? We make moral decisions every day, forming a moral personality from the choices we make about right and wrong…
Graphene: A single-layer magic material
You’re likely familiar with graphite: the chalky gray material we often refer to as pencil lead. In recent years, graphite has been making headlines due to increased interest in its younger sibling: graphene, lauded as a supermaterial of the new age for properties that hold out the promise of novel technological feats. Graphene has the potential to replace silicon-based computer chips, improve the performance of touchscreens, realize ultra-sensitive biometric sensor devices, and even faster charging and increased storage capacity in batteries and capacitors…
How did we find out that an asteroid killed the dinosaurs?
If you ask almost any kid today how the dinosaurs died, they’ll tell you an asteroid killed them, but this didn’t used to be the leading theory. When you look at key papers about the asteroid impact the kids are referring to, you’ll learn that it defined the transition from the Cretaceous to the Paleogene (K-Pg) boundary ~66 million years ago. Before the discovery of the asteroid, there wasn’t a single agreed upon theory on what caused the 5th global mass extinction…
The hunt for continuous gravitational waves
In 1916, Einstein predicted there are ripples in the fabric of space that travel through the universe at the speed of light. Today we know those ripples as gravitational waves. A century after Einstein’s prediction, science gave Einstein one of his biggest victories: the detection of gravitational waves. The detection came from gravitational waves emitted by black holes…
How gender is conveyed through speech
When we hear a voice, the speaker’s gender is one of the first things we notice about them. Even if we’re asked to categorize speakers based on dialect or accent, we still gravitate toward grouping them based on how we perceive their gender. In my lab, we study which specific physical properties of speech (known as acoustic cues) control how gender identity is perceived. The acoustic cues we examine are voice pitch (controlled by how quickly the vocal folds vibrate), voice resonance (a result of the size and shape of the throat and mouth), articulation (how we produce the consonant and vowel sounds in our speech), and intonation (the melody we produce with our speech)…
A study on grammar and the bilingual brain
We humans have a unique capacity to acquire language, even as adults. However, if you have ever used Duolingo, you might have realized that children are more successful at acquiring languages than adults. This observation is puzzling; since adults are smarter than children, shouldn’t it be the other way around? One set of explanations for this paradox focuses on parsing — that is, applying our knowledge of grammar as sentences unfold incrementally…
Seeing science in a different light
The first time I remember my malfunctioning eyes affecting my life was when I was younger than 5 years old. I was riding in my grandfather’s truck. We had reached a stop light, and my grandfather said we could go when the light turned green. I remember thinking “Green? That light is white.” This problem persisted all through K12 school, when a sea of classmates flashed colored pencils at me and asked, “What color is this?” I tried to explain that the issue isn’t interpreting a singular pencil of stark shade, but that it is distinguishing combinations like reds vs. greens that are close together, or greens vs. browns, or purples vs. pinks. This explanation often fell on deaf ears…
