Dr. Annie Arnold

Welcome at long last to the longest-standing member of the group... Dr. Annie Arnold! My fun fact: Annie actually joined the group before me in 2014-- I didn't join my own group until 2015. So, we've been waiting for her to write this bio for about 8 years now. She also didn't give me a picture, so please enjoy our very first Sydlik Group picture from June of 2015! (Annie on right if you had any doubt.) So without further ado, here she is:

Name: Anne Arnold

Hometown: Emporium, PA

Education/ Experience/ Awards:

PhD in Chemistry – Carnegie Mellon University

Focus: Designing biomaterials for tissue regeneration and heavy metal chelation therapy

MS in Biology – University of Massachusetts Lowell

BS in Chemistry – Saint Francis University

I’ve worked in the national lab system, including PNNL, where I earned an Outstanding

Performance Award for advancing 3D printing tech. At CMU, I also won a Three Minute Thesis

(3MT) award, showing my ability to break down complex science. My focus is on biomaterials

and carbon-based innovations.

Team Sydlik Member since: 2014 – 2019, 2024 – Present

Research Project: I am currently engaged in research focused on generating

biomacromolecules that effectively chelate heavy metals. This work involves designing and

synthesizing large biological molecules capable of binding and removing heavy metals, with

applications aimed at addressing contamination in biological and environmental systems.

Favorite thing about CMU/ the Sydlik Group: My favorite thing about the Sydlik group is the

supportive environment that drives creativity both inside and outside the lab. It’s a space where

collaboration and encouragement foster innovation, allowing us to push boundaries in research

and continuously grow as scientists and individuals.

Least favorite thing about CMU/ the Sydlik Group: Parking, or lack thereof.

Favorite thing to do in Pittsburgh: There are too many favorites to name just one! Some

highlights include visiting the science museums, exploring food festivals, checking out the Strip

District, and, of course, enjoying the amazing food.

Fun fact: Before heading to college, I apprenticed as a tattoo artist! I am also undefeated at the

Chubby Bunny challenge.

Joseph Dosch

If you didn't know it... undergraduate research is HUGE at Carnegie Mellon. It's where I got my start. Right here in what is now my very own labs-- but at that time they belonged to Dr. Rick McCullough. 

Today's researcher is part of our vibrant undergraduate research culture. Please say hi to Joe!

Name: Joseph Dosch

Hometown: Pittsburgh

Fun fact: Cannot solve a rubik's cube

I am Joe Dosch, a senior Chemistry major at Carnegie Mellon. I have been a part of the Sydlik lab working with Hunter Wood and Stella Trickett since the spring of 2023. My research involves analyzing the adsorbent properties of activated charcoal, synthesizing/characterizing peptide amphiphiles as a biocompatible adsorbent, and obeying Hunter’s demands. If I am not in the lab doing yet another NCA synthesis, I am probably doing homework, at a Steelers game, or playing ultimate frisbee for Carnegie Mellon’s club team.

Max (Chenyun) Deng

All these years later, I'm going to see if I can get the group members to finally introduce themselves on the website... first up is Max! Max joined the group in the fall of 2022 as a Biomedical Engineering MS student. After earning his MS in December he transitioned to a Research Assistant in the group and will be starting as a Chemistry PhD student in the fall. Even though he's been around for a while, we are excited to welcome Max!

Team Sydlik Takes MARM!

When I was a student, I always wondered why professors' websites were out of date. When I became a new professor, I chose to use a Blog for my website so it was easy to update... and yet here we are! Only one update in the last 5 years 😳😂😅 At least you can see from Google Scholar that we've been doing some fun science and from @bunniesofochem (Instagram) that bunnies have a good time with Team Sydlik! (Forget about X... once it stopped being Twitter, it stopped being fun.) Anyways, the truth of this matter is that professors have too much to do and too little time and if we don't update our websites, everyone in our group still gets paid and our courses still get taught. None of our promotion or retention is based on how good our website is... so it slips to the bottom of the priority list. That's not to say that recruiting is not important! I'm chair of our admissions committee so prospective graduate students are a top priority to me. If you have any questions, just reach out and ask! (And if you don't get a response the first time... try again! I get at least 100 emails I have to respond to for essentials every day, so often some slip through the cracks.)

Anyways. I promised my students that if they got ice cream together and sent me a picture, I would in turn update the website. So here goes...

Last week (June 5-8) Team Sydlik visited Penn State University for the ACS Mid-Atlantic Regional Meeting. 5 team members presented including Dr. Juhi Singh (PD), Walker Vickery (PhD 5), Sebastian Guarjardo (PhD 2), Jacob Kadir (UG), and Dr. Annie Arnold (Lab Manager/ Group Leader/ Cat Herder). Enriching science was shared and learned. The real highlight of the trip though, was the trip for group ice cream at the Penn State Creamery!

L to R: Sebastian, Walker, Juhi, Annie, Jacob.
I don't see proof of ice cream, but I trust that it was so good that it disappeared immediately ;)

Archived Welcome Page

 The old welcome page... retired June of 2024 (Yikes! 8 years already after it was created!)

The Sydlik Group is a polymer and material research group in the Chemistry Department at Carnegie Mellon University. We specialize in the design and synthesis of novel polymers and organic materials for use in electronic, mechanical, and biological applications.

The Sydlik Group works in the Mellon Institute (Group picture, April 2016)

And we have all. the. fun. in the lab! (First tissue sample, July 2016)

This one time, we got in a car together and drove all the way to Canada for a conference... #SydlikGroupSelfie (May 2016)

And sometimes I mandate fun: Spring Carnival 2016

Official group colors are lime green and ocean blue. (Prof Sydlik likes bicycles too.)

And there's a bunny. Follow him on Instagram! @ProfBiscuitSydlik
