Joost Vlassak is promoted to Full Professor with Tenure at Harvard

Joost J. Vlassak's pictureWe have just heard the great news that our colleague (iMechanician number 12), Joost Vlassak, has been promoted to Full Professor with Tenure at Harvard.

Joost studies mechanical behavior of materials, using a combination of experimental and theoretical approaches.  He has made seminal contributions to nanoindentation, chemical-mechanical polishing, and thin-film mechanics.

Congratulations, Joost!

Congratulation to your great achievements at Harvard!

I really enjoyed your lectures and our collaborations when I was at Harvard. Look forward to more research news from your group!

A side question, I'm wondering how many different tenure systems currently exist in the institutions in US, and around the world.

Congratulations, Joost!


Joost, this is a wonderful acknowledgment to your years of efforts, dedication, excellence, and great contributions to this field. You are a great scientist as well as a great teacher, and I was very lucky to have the opportunity of doing my PhD with you. I am very grateful to your guidance, advice, and encouragement over these years and I have learned not only knowledge but much more beyond from you. I must say that it's always been an honor and privilege to be your first PhD. Congratulations again!

Recently I am reading one of Vlassak et al.’s paper:

Xi Chen, Yong Xiang, Joost J. Vlassak (2006). Novel technique for
measuring the mechanical properties of porous materials by
nanoindentation. Journal of Material Research 21, 715-724.

There is an error.

For the statement under equation (8), it should be
S_ij = sigma_ij – sigma_m * delta_ij

Please check.

delta_ij was missing in this typo of stress deviator.  Since the correct equation was built in ABAQUS none of the results was affected. In fact we awared this typo after the publication of the paper, but since it's too minor we didn't send in a correction. Thank you for your careful reading and interest in our work, Honglai.

Also congratulations to Joost! I enjoyed working with you on many of the nanoindentation and bulge test problems, and look forward to more fruitful collaborations.

yeah, it is a typed error.

As a reader, so far I cannot find any more serious error in his publications. :)

Joost, all of us young professors aspire to be like you! I hope you did not get into any arguments with your committee after your tenure case review like you did with Professor Sinclair after your qualifying exam!

As a current member of Joost's research group I can vouch for his deserving this honor.  Joost is a great teacher, researcher and advisor.  It has been a pleasure working with him over the past few years, and I am looking forward to finishing my thesis with him.

Congratulations Joost!

Joost, Please accept congratulations from your third Ph.D. to be. When I read acknowledgements in other people's theses, I always imagined myself writing something similar one day. Now here I am. Joost, you are a great advisor. I am very grateful to your guidance over these years. You are also a great scientist. I appreciate and enjoy the numerous discussions we have been through. It is great to be here to see all this happen.

Many congratulations, Joost! I guess everybody sees this coming. I am fortunate to be one of the first Ph.D.'s under your guidance and witnessed the making of an outstanding professorship. It is truly an honor to work with and to learn from you.

Time to go sailing... Cheers!

Congratulations Joost!

I heard from Dr. Jaehyun Kim that you worked so hard and did a great.

Thanks for your contributions in the research.



Congratulations Joost!

I just found this great news. Thanks for your contribution in our fields.
