Thesis available online

Author: Aviral Vatsa
Finally the thesis is available online..click here. It is available via the university library website, hence all the chapters are not available individually. The thesis is under the file name Thesis Vatsa.pdf Whole of thesis? my god! ...don't worry a shortened version in the form of an abstract (in english and Dutch) is also available here... so you see no escape route ;). Good luck

Mechanosensing and Chemical Signaling in Single Osteocytes

Cover of my thesis book. If you find the topics (see papers below) interesting and wish to have a copy of the thesis, which has additional chapters than the papers, do not hesitate to contact me via the 'comments' section of this post. Currently the online version of the book is not available, but it will be accessible soon.

Made it..cover of journal Bone!!

I am thrilled to share that one of the images of my article has been selected for the cover of the journal Bone. This issue (Bone 43:3 sept 2008) has my article 'Osteocyte morphology in fibula and calvaria — Is there a role for mechanosensing?'
The image is a 3-D reconstruction of the osteocytes (bone cells) in the fibula bone. These reconstructions were made by using nanoCT scanning and a couple of other software. (for more details click here)

The Audio (public defense..in English)

In The Netherlands, the PhD defense is conducted in public. It lasts for an hour and starts with the opening by the Rector Magnificus. I had a 10 minute presentation aimed at apprising the audience of my phd work. This presentation is followed by questioning round of nearly 45 minutes. The candidate is questioned by around 10 experts of different fields (related to PhD work)who have been provided with the thesis work well in advance. The candidate has to survive this onslaught before he is saved by the bang of the beadle. After the questioning session the jury is adjourned to come back and announce the decision of the jury. After the decision the degree is handed over to the candidate and the next important step is ...party (see photos too below)
