Chemical Engineer — Sustainability & Supply Chain

Hi, I'm
Sophia.

B.S. Chemical Engineering, Carnegie Mellon University. Currently a Raw Materials Chemist at L'Oréal, with manufacturing experience and a minor in Science, Technology & Society. I came to supply chain through chemistry — and through two years of watching what actually happens between a sustainability strategy and a production floor.

Why supply chain, why now.

I didn't start with supply chain. I started with chemistry — the conviction that if you understand what something is made of and how it transforms, you understand most of what matters about it. Working on a manufacturing plant floor made that concrete: the distance between a company's sustainability goals and what actually happens in production lives in the supply chain. That's where I want to be — not writing the report about it, but in the room where the decisions get made.

I'm actively pursuing supply chain, direct sourcing, project management, and sustainability roles where I can bring technical engineering depth and real manufacturing operations experience.

Writing

Things
I've written.

I've always cared about making complex ideas understandable — not simplified, just translated. These pieces range from published articles to research papers to things I'm still working on. The common thread is trying to make something real feel real to someone who wasn't already convinced.

Science Communication · Energy for the Common Good · 2021

You've Seen This Before: Fusion in Science Fiction

I wrote this at 19 during an internship with Energy for the Common Good, a fusion energy nonprofit. The piece looks at how science fiction has shaped the way the public thinks about fusion — from Iron Man to Interstellar — and argues that cultural familiarity with an idea actually matters for whether people support it in the real world. It was my first real attempt at science communication for a general audience, and it taught me a lot about how to make technical ideas feel relevant to people who aren't scientists.

Finding the Line Between Profit and Patients: The Ethics of Pharmaceutical Detailing

This came out of Carnegie Mellon's Bioethics Program — I was one of 12 students selected — and was developed in collaboration with the Kennedy Institute of Ethics at Georgetown University. The paper looks at pharmaceutical detailing, which is the practice of marketing directly to physicians, and asks where the line sits between legitimate education and commercial influence. It also touches on direct-to-consumer advertising. It was published on the program's webpage and presented at a symposium.

Waste Does Not Exist: A Chemical Argument for Circular Industry

This is something I've believed since I first learned about conservation of mass. Matter doesn't disappear — it transforms. Which means what we call "waste" is really just matter whose next transformation we haven't figured out yet, or haven't bothered to prioritize. I want to write this piece for people who design products and supply chains, not just chemists — making the case that the circular economy isn't idealistic, it's just chemistry applied honestly.

The Trust Gap: Why Consumers Don't Believe Corporate Sustainability

Working in a manufacturing plant gives you a ground-level view of the distance between what gets announced in a sustainability report and what's actually happening on the floor. That gap is real, and consumers feel it even when they can't name it. I want to write about this honestly — what causes the trust gap, what it would actually take to close it, and why "better marketing" isn't the answer.

Redirecting the Machine: Oil Industry Infrastructure and the Circular Economy

I don't think the climate crisis is primarily an invention problem. A lot of what we need already exists — the infrastructure, the engineering expertise, even much of the capital — mostly inside the industries we're trying to move away from. This piece is about what redirection might actually look like, and why it's a more realistic path than waiting for something new to be built from scratch.

Speaking · Not Online

Alumni Panels: College Process & Women in Engineering

I've spoken on two alumni panels — one about navigating the college application process across different personalities and backgrounds, and one specifically for students pursuing engineering. Both were conversations I genuinely enjoyed. There's something useful about being close enough to the beginning of your career that you still remember what the hard parts actually feel like.

Panels — Not Online

Technical Writing

I can write clearly about complex topics without losing the accuracy. Between my ChemE training and my minor in Science, Technology & Society, I've spent a lot of time translating between technical and non-technical audiences. I've also given feedback on peers' and mentees' writing and genuinely enjoy that part of the process.

Science Communication

Getting people to care about something they don't already care about is a communication problem, not an intelligence problem. I'm interested in that challenge — particularly around sustainability and energy, where the gap between what's scientifically understood and what the public feels is still pretty wide.

Want to work together?

If you're working on science communication, sustainability writing, or making technical ideas accessible to a broader audience — I'd love to connect. Always open to a conversation.

Interested in
connecting?

I'm actively looking for opportunities in supply chain, sourcing, project management, and sustainability roles. Happy to chat about any of these projects in more depth too.

Hi, I'm Sophia.

I grew up in New Jersey and went to Carnegie Mellon for Chemical Engineering — partly because I wanted a real challenge, partly because I wanted to get out of my hometown bubble. Both happened, and I'm glad.

ChemE at CMU changes how you think. You stop seeing problems as isolated things and start seeing them as systems — variables, constraints, trade-offs, downstream consequences. That lens has stuck with me well beyond the coursework, and it shows up everywhere: in how I approach supply chain problems, in how I play chess, in how I think about sustainability.

I also minored in Science, Technology & Society — essentially a study of how technology and human society push and pull on each other. Combined with engineering, it gave me a way to ask not just "does this work?" but "what does it do to people?" That turns out to be the more interesting question in most of the work I care about. Right now I'm at L'Oréal as a Raw Materials Chemist, actively working toward supply chain and sourcing roles where I can bring this technical and operational background to decisions that actually shape what gets made and how.

Dance Performed in two Dancer's Symposium showcases at CMU. I need to feel music physically — it's never been an intellectual exercise for me.
Soccer Defensive wing, CMU Women's Club Soccer. Reading the game early and cutting off problems before they develop — that comes naturally.
Chess Self-taught, purely positional player. Built a Python chess engine for fun. I like the slow build — quietly making it impossible for your opponent to find a good move.
Piano Picked it up early and took to it naturally. Structure and feel at the same time, two hands doing different things in service of one thing.
Poker The social psychology is the interesting part — reading what someone is building toward before they show it. The cards are almost incidental.
Speaking Two alumni panels — the college process and Women in Engineering. Took acting classes specifically to get better at storytelling. I think about how things land.

Perspective

Some things
I actually believe.

These aren't conclusions I arrived at through study — most of them I held intuitively before I had the language or science to back them up. I've always thought in connections: a principle from one place tends to show up somewhere else. Chemistry informing how I think about learning. Soccer defending informing how I think about supply chain risk. Chess informing strategy. That's not deliberate — it's just how my brain works. The ideas below are the ones that feel most central, coming from chemistry, observation, and caring about the gap between what companies say they're doing and what's actually happening. I studied ChemE with a minor in Science, Technology & Society — the technical side and the human side, and the friction between them. If any of this resonates, or if you disagree, I'd genuinely love to talk about it.

01

Everything, at its core, is chemistry.

I've believed this since 10th grade chemistry. Biology requires life. Physics requires movement. Chemistry only requires matter — which is everywhere, which is everything. It's the most foundational lens I know, and it's the one I keep coming back to when I'm trying to understand how something actually works underneath all the complexity on the surface.

02

Waste doesn't really exist.

Matter is never destroyed — it transforms. That's basic conservation of mass, and it means what we call "waste" is just matter whose next transformation we haven't figured out yet, or haven't prioritized finding. The circular economy isn't idealistic. It's just chemistry applied honestly to how we design products and supply chains. I think we'd make very different decisions if we started from that premise.

03

Impact has to be felt, not just demonstrated.

Data alone doesn't change how people feel about something. I care about this a lot in the context of sustainability — companies put out impressive numbers, but consumers don't feel that anything is different. That gap isn't a communications problem you can fix with better marketing. It's a gap between what's actually happening and what people experience. Closing it requires honesty first, then communication.

04

We already have most of what we need.

I don't think the climate crisis is waiting on a breakthrough invention. The knowledge exists. A lot of the infrastructure exists. The capital definitely exists — much of it inside the industries causing the problem. What's missing is the will and the mechanism to redirect those resources. That's a political and organizational challenge as much as a technical one. But it's a solvable one, which is why I still find it worth working toward.

05

Thought is a physical thing.

The brain is physical. The brain thinks. So thought is physical — neurons firing, synapses forming, physical bonds being made and strengthened. And I've noticed that I learn best by connecting new things to things I already know, which makes sense: it's easier for your brain to form a new connection at an existing node than to build something entirely from scratch. Learning through connection isn't just a study trick. It's how the underlying chemistry actually works.

"I think we already have most of what we need to make circular economy thinking a reality in every household. The harder problem is getting it pointed in the right direction."

This is where the chemistry worldview and the sustainability work come together for me. It's not about waiting for a breakthrough. It's about redirecting what already exists — and making it feel real and accessible to the people it's supposed to serve.
