Grammarly thinks that I use the word strain too much. It suggests the following alternative words for strain: stress, pressure, action, and music (!). Also Grammarly is suggesting I use power instead of energy. Grammarly needs a lesson in physics.

Huajian Gao giving another engaging and insightful talk at the the Emerging Topics in Mechanics workshop, celebrating his 60th birthday. He is a masterful writer, presenter, and scientist. Happy 60th Birthday Huajian. I’m luckily to have been your student.
Congratulations to Zheliang Wang on the successful defense of his dissertation "The Toughness and Residual Stresses of Polymers Produced by Fused Filament Fabrication". The last thing I get to teach him is how to open a champagne bottle. Zheliang will join
@nanshulu
as a postdoc.
Huajian Gao, a legend in mechanics, honoring/roasting his best friend, former office mate, a fellow Musketeer, and also legend, Yonggang Huang. Little known fact: Huajian is an excellent comedian.
New Nguyen Lab photo. We are a good-looking bunch! My group is unusually large this semester as some students are finishing up, and new students are joining.

Proud to announce our NSF 2021 DMREF Award: Materials Architected by Adaptive Processing. Excited to continue to work with our collaborators at NIST and Georgetown and with new collaborators at UMass Lowell and AFRL.
What causes the rate-dependent, dissipative behavior of liquid crystal elastomers (LCEs)?
@SGovindjee
, our students, and I developed a nonlinear viscoelastic micropolar theory for monodomain nematic LCEs to test out 2 mechanisms:
Kaushik Battacharya giving the Physics Colloquium lecture at Princeton on Liquid Crystal Elastomer. Can you tell what is one of my current favorite research area?
No science today. I am going home after a fantastic trip. 3 talks at 3 conferences in 3 countries. It was wonderful to be back in Europe and trip went absolutely smoothly. I even got to spend a beautiful sunny day in London yesterday. Happy Easter! Happy Spring! Be back soon.
I’ve been on vacation with family in Iceland and now Stockholm. I usually don’t post personal things on twitter but the natural wonders of Iceland are too beautiful not to share.

on Irregular Metamaterials. Looking forward to the next couple of days of the conference.
This May 2018 memory popped up on my Photos. Classes had just ended and I was dulging in a morning doing my favorite mechanics thing, constitutive modeling. May and January are two times in the year I get to be the hermit scientist. Happy Holiday Break!
Thank you to my nominator (you know who you are!) for your support. Thank you, everyone, for your congratulations! It's an honor to be part of the AIMBE's College of Fellows.

's College of Fellows — among the highest professional distinctions accorded to medical and biomedical engineers.
Happy to share our new Advanced Materials paper on architected LCEs. It's partly a story of how computational modeling can take apart a complex problem, examine the importance of each part & explain how to put them back together to make a better material.
Very excited to introduce the office twitter voice for the Journal of Biomechanical Engineering. Follow

Journal of Biomechanical Engineering is searching for Associate Editors in charge of publicizing papers published in JBME. The Associate Editors will work with the Editors-in-Chief to identify exciting newly accepted manuscripts and to highlight them on social media channels.
Cameron Czerpak did an amazing job giving a talk on in vivo measurement is optic nerve head at SB3C. So great to see your students do great. So great to see your students live at a conference!
First lecture went well! Thanks for all your kind response to my last tweet It’s amazing that after 15 years I am still nervous teaching undergrads. Undergrad classes need more prep and the lectures require a lot more energy. Grad classes are a breeze in comparison.
And that’s a wrap on

Breakfast with Sarah Bentil, assistant professor in ME at Iowa State. Sarah was a former postdoctoral member of the lab. Now, 6 years later, just graduated two of her own students and managing a successful research program in TBI.
We had a lovely farewell dinner for Arina Korneva (center) who will be starting as an Assistant Professor. She will make formal announcement when she starts in September. Very proud of you Arina. We will miss you. Enjoy your new adventure.
The International Union of Theoretical and Applied Mechanics is soliciting proposal for symposia and summer schools for 2024/2025. Pick a topic you're passionate about and a beautiful location to hang out with colleagues and friends.
Congratulations to Tracy on her successful dissertation defense! She delivered a great presentation on "The Effects of Microstructure on the Pressure-Induced Mechanical Response of the Optic Nerve Head." Dr. Yik Tung Tracy Ling will join

Our paper on measuring the pressure-induced strain response of the optic nerve head (ONH) in glaucoma patients was just accepted in Ophthalmology Glaucoma.
Our work on the extreme dissipation of liquid crystal elastomers was featured as a success story in the 2021 ARO year in review. If you're interested, it's on page 58 of the pdf. Download here:

Invigorating hike up to Booth Falls. 2000 ft elevation gain from 9000ft. Rocky climbs, fast moving water crossings. Cameron was glad he didn’t kill his advisor. I was glad to not embarrass myself in front of Cameron.
Really impressive talks this first morning at Euromech Colloquium Current Challenges in Soft Tissues. Thanks
@StphaneAvril1
and Christopher Blase for organizing. Some of my favorites from this morning were from Jay Humphrey, Sandra Loerakker, Grace O’Connel, and Christian Cyron.
More than a conference, it was a reunion and a celebration. Happy birthday, Yonggang. Thank you for all that you do for the mechanics community and your junior colleagues.
Our latest paper online at
@JBMEjournal
shows that The LC of glaucoma eyes has a stiffer pressure-strain response, but larger curvature, larger area, and more curved beams than normal eyes. This suggests that the LC has a stiffer elastic properties.
Congratulations to Yupin Shi (3rd from front on right) on your MSE and new position as design engineer at Hospital for Special Surgery in NYC! Farewell lunch at Water Song Yunan Kitchen.

I finally had a chance to sit down and ask ChatGPT some questions. One question I asked, "A column is 1 m tall and 10 cm in diameter. Is it going to buckle under 100 N of force?" It didn't get the answer right, but it knew that my question was missing a Young's modulus.
Did you know that the ASME Bioengineering Division awards the Richard Skalak Award every year to the best paper published in JBME? Papers are nominated by associate editors and the winner is selected by an independent committee. Belated congratulations to the 2020 winners.

Our latest effort on modeling the thermo responsive behavior of hydrogels for soft robotics has been published! We asked how an asymmetric body design can produce a net forward motion during a cooling/heating cycle.
Our latest work on thermo-responsive hydrogel crawler is published in Science Robotics. We did finite element simulations to explain locomotion from frictional asymmetry induced by morphology.

Women professors tend to get inappropriate comments from students more so than men. A lot worse appears on our teaching evaluations. You are right that it’s good to talk to students, it’s just that it can be more of a minefield for women professors.
Kalyn Younger, started in my lab during COVID, at her first conference explaining her research to a crowd. She’s having a great time. Its wonderful to see.
Will Cortez gave a great talk on an experimental platform for studying the growth and remodeling of collagen tissue constructs. Will is a PhD student of Dan Reich in Physics at JHU and our collaborator on studying the micromechanisms of collagen growth and remodeling.
